Lennox Reviews

I've been a HVAC repairman and installer since 1987 and have been servicing and Installing Lennox products for years. Love the product. Reliable, quality, durable furnaces and air conditioners. You can't go wrong with Lennox units

Within days of our warranty expiration (only 5 yrs from the date of installation), we realized our a.c. unit had failed. Turned out to be a leak in the coil. Of course, Lennox would not honor the warranty even though the a.c. unit was installed over a month after the coil and well within 5 yrs, and the leak had obviously been going on for some time prior to any warranty expiration. So... about $2800 later we have a new coil. The Lennox rep I spoke with on the phone acknowledged the reality that we would never buy another Lennox. He could've cared less about our dissatisfaction. I followed up with an email to the company requesting them to review the situation, to which I never even received the courtesy of a response.

My Lennox a/c has been a lemon since I purchased it about 8 years ago. I have spent almost 3000 dollars putting in parts under warranty. Compressor went after first year. Cools replaced twice. Fan motor replaced twice. And something else. Unit keeps clogging up with slime. I have reported to lennox more than once. Reply... So sorry. Do nothing. I sent copies of all problems and cost receipts. I wouldn't recommend buying a lennox. You can understand why!!! I gave a 1 star because there are no o stars.

We purchased a Lennox in 2019 who would have thought we would needs a new unit in 2025; Leaking Lennox is true to their name. Take a chance on anything beside Lennox and crook of salesmen too. The crook for the Lennox product wanted us the consumer to pay, 5k for a repair, when we could put another 5k and get a new in and out unit product for our house. Then when we tried to get the coil to have it replace by another company, the Lennox warehouse in Mobile kept telling us our unit was never registered but every time we spoked to the salesman who sold the unit to us, he kept saying it was and we need to speak to someone in the back. Now, this sound like some kind undercover, illegal paper work that was not process in the beginning. The found desk person have no record but the person in the back does. Stay away, and follow your instinct when you are dealing with people like that.

We have purchased two Lennox systems in the last 10 years. One for the upstairs (heat pump) and a furnace unit for the main and basement levels. We will NEVER purchase another Lennox unit again. The upstairs unit is being replaced this week with Carrier. Three years ago, the blower motor was replaced under warranty for the upstairs unit. The last AC checkup indicated that the TXV was operating out of range and now refrigerant is leaking from the copper evaporator coil. Total repair cost is estimated at about $5K. There was a class action suit against Lennox back in 2016, a few months before we purchased the upstairs unit. No notification from Lennox or anyone.

The former owner bought this new furnace from Lennox in February 2020. Unfortunately, the owner sold it to me in September 2021 because he had to go to dementia care. The control panel went out in the furnace and because they said I’m the second owner I don’t have coverage for the 10 year warranty! Please go easy on yourself and don’t order any Lennox products. They don’t care about us consumers, evidently they only care about their commercial clientele.

HIGH HUMIDITY HIGH EFFICIENCY FURNACE. They know this, yet they do not include a dehumidifier. Caused breathing problems and coughing since unit installed. I had a UV light installed and a separate dehumidifier, 600$ more to spend. Unit was 17,000$. DO BETTER, LENNOX, a lot of bad reviews. CLASS ACTION LAW SUIT for all units replaced to restore your reputation. Lifetime warranty on all parts and units. A dehumidifier with a humidifier attached.

Ac unit went out after a little over 4 years. The entire unit had metal shavings, Needed a compressor, Needed reversing valve, Condensing coil, and there was Metallic debris throughout outdoor unit. Was still under warranty however, Lennox did not want to give me a new unit. I ended up installing another brand and will not recommend Lennox due to quality of product and warranty or lack there of.

I bought a new Lennox system in December 2018. I was told it would be more efficient than my old Trane system that was still functioning. Two months later, right in the middle of winter while I'm in the hospital, the unit won't work. It came with a defective part. Finally, after a full day with my condo at 40 F, it was finally working again. Now, six years later, the unit doesn't work again and the technicians are stumped. It is incredibly unreliable and overpriced.

This company will NOT disclose what an individual would pay for one of their units. It becomes impossible then to find out what the contractor has marked the unit up thus opening the homeowner up to possible price gouging by the install company. This practice should not be condoned. It should be up to the individual that ends up paying for the unit in the end to be able to calculate what the actual markup is so as not to get ripped off. This is especially important for the elderly, disabled, and anyone else that is not aware of average pricing within the industry. I can understand not selling direct to a homeowner but to not disclose pricing should be criminal in this day an age.

The Lennox unit came with the new build in 2022. On one of warmest days in October my unit stops working. After being on hold for more than an hour, I was forced to call an independent contractor. Once repaired I was informed that the motor stopped working because it was installed in 2019. How can that be in a 2022 new construction? Two options, either the unit was used or the part was used, either way it has not survived the 5 years it was promised. Now I am out of almost $500 and no one at the repair or warranty department will answer my call. My most recent attempt used 2 hours of my time on hold. If you are going to cheat someone at the very least entertain their complaints. In this economy, no one wants to spend unnecessary money. Piss poor.

We will never buy a Lennox A/C unit again. These systems come with only a 5-year warranty, and in our experience, they simply don’t last. We live in a five-year-old new build, and our builder, Darling Homes (Taylor **), installed Lennox units. Last year, the coils failed on the smaller unit and had to be repaired. This year, the same issue occurred with the larger unit—but now the parts are no longer under warranty. I even reached out to the CEO and received no response. Their Consumer Affairs department essentially told us, "too bad, sorry." Now, we’re stuck paying $6,900 out of pocket for a new system on a house that's only five years old. Extremely disappointed in both the product quality and customer service.

Evap coils leaking after just 5 years. Not under warranty by 1 day. This is the builder's equipment by choice. Two other houses in my sub have had the same problems. Coils leaking way before they should. JUNK!!

I have three Lennox Heating and AC systems in three of my homes and I am extremely unhappy with this company. They sell very expensive and substandard equipment that goes bad easily. They sell their equipment through a network of dealers. If you try to get service however through Lennox as a consumer, that service is non-existent. They will not honor their parts warranty directly to consumers and they will insist that you use one of their dealers. I had a few months ago two Lenox S40 thermostats go out when the power to the house was interrupted and reinstated. These thermostats cost well over $1500.00 each!!!! The just now, I have the blower fan motor go out on one of my units.

We purchased this product after being assured it came with a ten-year warranty, provided we kept up with the recommended annual service. Unfortunately, when a problem arose and we reached out for assistance, we were surprised to learn that the coverage was not what had been represented at the time of sale. The response we received from customer service was extremely disappointing. The representative showed little compassion or understanding for our situation, and their tone came across as short, rude, and inconsiderate. Rather than helping us navigate a solution, they simply dismissed our concerns without explaining any next steps or offering meaningful guidance.

I purchased a Lennox Elite system from J&W heating and air 14 months ago. It has constantly been a problem and now the system has failed completely. Lennox is holding J&W in Jacksonville hostage because they do not keep Parts in stock apparently. You realize how hot it gets in Florida to be without HVAC system for a week? This is totally unacceptable. I would never buy another Lennox product again.

Equipment is trash. Paid $13,000 for a complete system with ductwork. Cool Today did a completely disgusting job installing and the unit lasted 6 years. I had a different contractor check the system and said the compressor was dead. Lennox told him they did not have any in stock and that if he found a similar compressor, they would reimburse his purchase. Labor to have this replaced $2500.

I recently contacted Lennox customer support on the warranty on my air conditioner, model number 13ACXN024-230. After a few months of the base 5 year warranty, the compressor failed. It would appear that many folks have experienced similar problems with their units within or just outside the base warranty period as per reviews that I have seen. Apparently, Lennox provides an additional 5 year warranty, however, it has to be registered within 60 days the unit is installed or take ownership of the home if purchased from a builder. Unfortunately, the Builder/installer did not register the unit and I was not made aware of this and therefore couldn’t register the unit myself. It’s rather frustrating and disappointing that Lennox would not make any allowances to consider honouring the 10 year warranty, regardless the unit is registered or not. Frustrating and dissatisfied customer.

Hi. My name is Sam **. I purchased a Lennox central air conditioner 2 years ago. It worked good the first year. Second year it started to smell funny and it was noisy. I called the dealer that I bought it from. Told him it was in September so I said there's no sense coming now, I will call you In May next year and don't forget the first year it's only 4 months old. I used it the next year. Was the same so really I used it for eight months. 5 of those months it worked ok. When I called in May for the contractor to come check it they came, said it was the compressor and it's under warranty. This was a Saturday when they came out. I said so when are you going to replace it. They said it could be one or two days or three weeks. I said what that's not acceptable. They said it comes from lennox so after 4 weeks nothing. I called. The contractor said they were still waiting so I called lennox myself for the first time of at least 20 calls.

Had a brand new Lennox system installed in our new house 2 1/2 years ago by their local dealer. Starting having problems with cooling 1 1/2 years in. Took dealer up till now to actually diagnose the problem. Pump has gone bad and condenser has gone bad. Lennox will not honor the 10 year warranty. Lennox will not supply parts at no cost to repair air conditioning system. Going to cost us over $10,000 to repair a system that is less than 3 years old. Lennox has had class action lawsuits on their equipment. Worst company and air conditioning you can put in your house.

I would stay far away from this brand. I paid 12,000 for an AC unit for it to last not even 9 years. The evaporation coil went and they no longer manufacture it. I had to get a whole new system from another brand. I see the lawsuit that took place as well. They knowingly put out parts that were faulty to begin with. Save yourself and don’t go near this company.

This product failed in less than 1.5 years leaving me with a $1350 bill after spending $8300 on a whole new unit. Lennox already settled a major lawsuit on the same issue in 2015 and continue to sell this problem product.😡

I installed Lennox AC in 2017. My coil starts with CH35-. I am in Texas. I have two AC systems installed from Integrated Mechanical and Electric Service, LLC (IME Serbice). I did not know these AC has defects of coil. The company didn’t tell me anything about this. Now, my coil is totally malfunctioning; I have a certified technician filed a claim since mid-April, 2025; however, I did not coil yet. It has been three months. It is so hot in my house. We have gotten case number but LENNOX keeps telling us no coil available. Do not buy this brand AC since it does not really has warranty. We are so helpless right now because it is scorching in Texas.

I have a 12 year old Lennox high end system that ran me 15K and it died for the 6 or 7th time. I must of gone through every Lennox deal in the area and they all suck. The worst being Engineered Air who way oversold me, and put the wrong Air Handler in. It was way too big and with enough grease and a crowbar, they got it to fit. Over the years, several circuit boards, 6 smart thermostats. Well it died for the last time 3 days ago and no one wants to even look for it. Lennox corporate pretty much blew me off. So we just bought a new system and we went with a different vendor. The hell with you.

I bought a New home with a Lennox AC unit that is only 4 years old. The Compressor went out which is covered under warranty, however the $2,500 in labor is not. I will just purchase a New unit from a better brand and will never recommend Lennox Junk to anyone ever!!!

Based on the recommendations of a HVAC Contractor with whom I had maintenance contract for years, I replaced my HVAC system with Lennox system in December 2022. I turned on the air conditioner beginning of this summer (108 degrees F). It did not work. The Contractor's technician came on maintenance day and charged me $495 saying the refrigerant was leaking. A technician is coming on July 16, 2025, to diagnose the problem. I do not know the expenses I will be incurring. I should have reviewed the equipment online instead of relying on the Contractor. It is unfortunate if a trusted contractor prefers profit over trust. I hope there will be another class action suit against Lenox.

Hello, I purchased a Lennox Heating & Air Conditioning back in 2018 together and in 2023 I found out I have a leak which is not keeping the refrigerant in and therefore I made calls to Company I use and they also referred me to Lennox Customer Service rep. During that time they only indicated about certain warranty & how long it last & what is not covered. However, two weeks ago I turn on my AC. The house never got cool & after the service tech came over to do a routine service & now it's my compressor is gone. Today I'm having to purchase a whole new unit I'm very pissed at this point.

Our air conditioner is about 9 years old and starting to have problems. That's okay, but Lennox doesn't even make a couple of the parts we need. Abandoning customers so soon after buying doesn't seem like good customer service to me, and if we do need to buy a new a/c it won't be a Lennox. Do yourself a favor and be sure to compare with other brands' service and reliability because somebody just has to be better than this!

Lennox does NOT stand behind their product. A local contractor out of Palmetto Florida advised me I needed a replacement so we replaced a 6yr old Lennox with a new Lennox system (air handler, condenser, thermostat). The fan blade was replaced jn a week. The thermostat was next. After a hurricane our air conditioner stopped working & because it was only a year old I called the installer. He said the blower motor seized up “due to a power surge”. We have a whole house surge protector but we needed the house cool. So we paid $1800 for the part to be replaced.

There is no option to select less than 1 star otherwise I would prefer to give less than 1 star. I bought a new AC which had a huge noise. after installation within 1 month, it stopped working. I called the mechanic who installed, he predict there might be some issue with Compressor itself. Hence, he flushed the Gas from the unit and then refill the new one. However, AC is not working at all on the Hot days of the summer. I called Lennox support, they said, we only replace the faulty part but not taking any responsibility of the whole Faulty unit. I had email everywhere in Lennox but no one on this earth available to respond or hear the problem. Support only give you Robotic responses. Even, if someone spend hefty amount (as per Lennox, that's not their responsibility) they have to live with this Lousy and Pathetic product. My case number just for reference: **

The worst!!! Installed 2 and one is so noisy I cannot use the bedroom near to it. Lennox refuse to replace it and say it is normal! So I guess the quiet one is not normal. Buy another brand and stay away. Oh, and don’t bother calling Lennox, you will be on hold for hours. Great customer service.

I had a furnace and an AC unit installed in late 2020. I have had no less than 20 visits to fix my heat. Now I have had a problem with the AC. I need an evap coil. Even though it is under warranty it's not available. Can't even get someone on the phone or a chat. I would never get anything from Lennox again. Unfortunately, I got rid of a Trane which never gave me a problem on 10 years. Just thought that I should do it at the same time. DON'T EVER GET LENNOX.

2 blower motors in 5 years with the first one right after warranty and the second one 2 years later. The energy saved doesn't cover the repair cost several times over. Not worth the repair costs for saved energy savings.

Lennox does not have product quality. They will offer a new part to replace one that should not have to be replaced within 3yrs new. No offer to pay labor to repair. Our ac was new in new build house but was broke before we moved in. So now a second part on a 3 yr old ac. DO NOT BUY Lennox. YOU WILL BE SORRY. They snub customer and do not stand up to quality.

I have a 5 year old unit. Coil went bad - $3500. Repair. The coil was the same serial number as bad coils in class action lawsuit that was settled a few years ago. A company with zero integrity. I contacted corporate office and they just blew me off.

I bought a Lennox unit based on other friends' recommendations. I made a bad choice. I have had more problems with this unit than with any other unit I have ever owned. I called their customer service line numerous times and could never get through. They put me on infinite hold. The company that installed the unit is out of business. Their installation job left something to be desired, however despite numerous repairs and corrections to the installation, the unit still has problems.

Do not go near this joke of a company. We have a top top top of the line system that cost $18000 in 2017 and about $25 000 today for a 2200 sq ft home - That's top end. We are on third coil replacement (costs over $1000 each time to replace) and third thermostat replacement (costs over $1000 each time) in 8 years of ownership of a top of the range system.

Had the Lennox SL280UH Furnace installed two weeks ago (5/30/25) and we've had 6 "Service Urgent Alerts" because the furnace was not working due to a "GF Ignition Circuit Fault." Techs from the install company have responded, got it going again, only to be followed by another circuit fault. They now have an order in for a new circuit board and ignition switch. Very disappointing considering this is brand new.

I bought a new Machine for air conditioning. After 3 weeks it breaks and it is impossible to contact them. They only have an email address, no answer and I already passed 3 weeks. There are 32 degrees outside and I will probably have a technician coming in my house by august if I am lucky. No technician can fix it because if not, I will lose the warranty. This is horrible, I hope no one else buy anything from this company. In my building there is another family that has a Lennox machine and it has the same problem. The machines has very bad quality and no support service available.

Had the unit installed in 2012. Exchange unit started leaking (2017) due to sorry welding. Unit replaced had to pay for labor $1400. Dec 2023 blower motor went out. Paid $2400. June 2024 motor burned.

The unit was poorly installed and seemed to cool less than other units in the building. It was installed in 2019 and nearly 5 years old and it is no longer cooling as well only a 6 F degree drop across. The unit leaks water into the pan which a hole in it and there was water on the floor. There wasn't rust in area near the hole so not understanding how the hole got there except parts were not inspected by the installer.

We purchased the unit listed below after doing due diligence, only to find out that after one year, the unit screen had to be thoroughly cleaned because the A/C did not work. Now, after five years, a major component needs to be replaced, costing $3,000, with the part being covered by the warranty, which is 50% of the cost of the unit, with the installation cost at $1,900. The A/C unit with a condenser costs $4200.

I made a Purchase form Reliant Air and my furnace was short cycling for a month and half. I thought the product was trash from looking at all the bad reviews. I had a Technician come out several times to help with the problem and they finally figured it out, so am updating my review to well done. Thank you.

I’ve had my Lennox 2 ton unit for 7 years. In year 6 the coils blew out, and the refrigerant alone was $350.00 to replace, then another $2,300 for new coils and installation. They lasted 4 months. Blew out again!!!! and this time Lennox picked up the tab, which they should have since they use poorly manufactured cooper coils. 2 years later, same problem. The coils have leaks again, all coolant gone. It’s over 100 degrees here all summer. 106 last Saturday, 5/31. Lennox refuses to fix my unit. Says it’s too bad. Unit is 8 years old, will give a small discount on a new unit instead. Or another copper coil to be installed at $3,750, at my expense. Unacceptable!!!!

Brand new LennoxA/C system in 2020. Five years later the coil goes out. Leak (due to cheap thin copper they use). Fortunately I have 2 months left on my warranty, coil is covered but have to order from Canada (to USA). That's the only one there is. Might get here in 2 weeks. Have to pay 800$ to replace it. Already had to pay emergency repair visit, 90 degrees in SC. Financial stress on top of this economy. Other brands last longer.

I have a top of the line Daves Signature with their ICOMFORT S30 Thermostat. They asked to do a new update and it blew the Thermostat and the Wifi relay to it. I was on hold for 1 hr with them and finally hung up. AC company said they have to order from Lennox. It's 93 here. I can't even get a call back when the parts will be here. The worst and it's their fault.

I purchased an ECM Lennox heater 10 years ago (final install inspection: 4/2). The blower motor failed on 5/11—just 1 month and 9 days after the 10-year warranty expired. When I contacted Lennox customer support, I hoped they’d make an exception given how close it was to the warranty period, as a sign of standing behind their product. Instead, I was told no exceptions are made—period. To escalate the issue, I was transferred to another queue. After waiting 5 minutes, the call disconnected. I called back, waited another 5 minutes, and was disconnected again. No callback, no resolution, just wasted time.

I purchased a new construction home in 2023 and already the coils from the Lennox ac unit have failed and are leaking! It hasn’t even been 2 complete years since I moved in here!! Now to top it off I’m at home with no AC. 85 degrees with kids in the house waiting for Lennox to get the coils from out of state!! I will never recommend anyone to get anything Lennox. They are a horrible company!!!!

Lennox filter sizes are a complete joke! Your employees don’t even know how to look up the proper filter sizes for YOUR filter cabinets! I had to hang up on your counter guy in Marietta for getting a rude attitude for not knowing how to properly find what I needed.. I gave existing filter sizes, and the cabinet model number and ALWAYS NEVER FAILS. Your counter guys are CLUELESS!!!

I do not understand how this company is still on the market. They have coil leakage issues for years and do not fix anything. I have 5 Lennox AC units, in 5 years,I had to replace 4 coils. I will never buy a house with a Lennox unit anymore. Shame on this company. I wish I can be part of a committee and put them to the court. They are literally robbing all their Customers and do not fix any of their major issues.

Subject: Severe Product Defect & Lack of Support from Lennox – CBX25UH Coil Failure. In December 2024, I purchased a home built in 2017. When I first used the air conditioning system in April 2025, I discovered that although the unit was running, it was only blowing hot air. A licensed HVAC technician inspected the system and found a massive coil failure — specifically, a large hole in the coil — making the system inoperable. What’s more concerning is the technician’s observation that the extent of corrosion was far beyond normal wear and tear and consistent with premature and severe deterioration. This strongly suggests a manufacturing defect or substandard materials.

We had 3 lennox ML17XP1 installed and have nothing but issues with both rooftop units and coils within 12 months, we had to have two of the coils completely replace and one rooftop also replaced. Now the installers found a hole in the copper tubing within the rooftop unit. To fix this problem it's going to cost between $2500 and $ 3000. Lennox is saying that it's not under warranty, even though it looks like it a design fault.

Being an elderly person I had to have constant repairs on my old unit which cost too much money. The decision was made to purchase Lennox top of the line Air Conditioner unit in hopes I would not have any issues for at least 10 years. Here it is less than 5 years and already having issues with their top of the line AC unit. The picture showing the leaky coil will cost me 2K to fix. It is a problem that Lennox has not fixed since there have been reports. Homeowners are spending hundreds and thousands of dollars on Lennox air conditioner troubleshooting, plus multiple repairs and replacements of the Lennox coil.

Lennox furnace was having issues, figured it out to be the circuit board. Had it replaced. Just over a year later, circuit board failed again, called Lennox and they wouldn’t help at all, price increased dramatically. Customer service said nothing they can do. Hope this new one doesn’t fail in 13 months and be out of warranty again. Last one may have blown my thermostat, who knows, not happy with Lennox’s unwillingness to help even in the slightest. This is why we dislike large corporations who gouge customers and don’t support them when it’s the right thing to do.

The customer helpline is horrible and did not want to answer any questions. Big mistake purchasing a Lennox heat pump, nothing but issues with it. My wife told me to get a York heat pump as we had one for 20 years with no issue.

Stay away from Lennox,,,cheap crap.... 8 month old furnace and a/c... Nothing but trouble the thermostat they give you...ecobee is also junk.... It changes temp. By itself and the house is always cold.

Purchased a Lennox Wall Mount heat pump on July 23, 2023 from their distributor Habitation AC. December 20, 2024 the unit began malfunctioning. Contacted Lennox and they said to return to the distributor. After several unanswered calls and emails, contacted Lennox again to request a service call. Lennox has still not responded. Now today February 19, 2025 we had to contact a company that came, examined the unit to be informed that the outdoor unit has a freon leak and the interior unit has a defective motor.

On 2/17/25 I contacted Lennox to let them know that the technical information regarding the DELAY JUMPER for the CBK45UHVT air handler is incorrect (I suspect the information is wrong on many models using the variable speed motor). I am an electrical engineer so I was confounded when adjusting the air handler motor delay operation per the instruction manual. In an effort to help Lennox out on what I learned - I provided detailed information and asked to be forwarded to Lennox Engineering so they could address my findings and correct their product literature. The Lennox rep said he would forward the info to his supervisor with no commitment to get back to me. He recommended that I contact consumer affairs so I am writing this review. I am trying to do a good deed and let Lennox Engineering know of the flaws. I am happy to take a call from Lennox engineering to go over my findings.

We are so disappointed in our 2 year old Lennox air handler: Model CBA25UHV-036-230 Fan Coil/3.0 ton/230-1. This is our third Lennox air handler in 10 years. Each unit had to be replaced due to refrigerant leaks in the evaporator coil. The first two air handlers had copper tubing. This current one has aluminum tubing. While the Lennox warrantee does cover parts, labor and refrigerant costs are not covered. Each air handler replacement or repair has cost over $3,600.00 for labor and refrigerant. So these air handlers have cost us over $10,000.00 in repairs (about $1000.00 a year). Plus the added cost of poor energy efficiency.

12 months ago I purchased a Lennox EL18XPV heat pump. It came with a leak in the reversing valve from the company and after wasting technician time and refrigerant, they finally discovered the problem. But the heat and cooling were never all that good, then last week the reversing valve is leaking again! Lennox says I need to hire my own HVAC tech and they will supply the part under warranty but the labor cost is on me. Even though this unit has been broken from the get-go, Lennox refuses to fix it. At this point, I'm ready to junk this unit. I spoke to customer support and they kept repeating the same message. I can not recommend Lennox products and the company. I have spent over $2k on technicians and refrigerant and still have no heat. I live in Maine and it's been in the single digits overnight. Lennox doesn't care.

Bought the top of the line heat pump system Jan 2023. While the A/C part of the system is good, the cost for heating for one month was $1400. The auxiliary heat was on when the outside temp was 55 and I keep my house in the mid 60s. I wish I never bought it. Will never buy another Lennox product again.

I’m very disappointed with the products purchased. They don’t compare in quality to the previous Lennox heat and air systems installed when I built my home 20 years ago. Low quality heat and air as well as being exceptionally noisy. I wish I could return and start over! Highly disappointed. Nearly 30 gran wasted. 1 Star rating on all 3 products. My bills are the highest they have been Since making this purchase. Fix your survey form!

Paid almost 12000.00 for new unit in 2019 and still making monthly payments. Now have to pay for heat strip not working 938.00. No 10 year warranty. Told it was not registered. I am extremely upset about this unit and will never buy another one. Plumber said he will cover cost of part because he tries to do right. I bought the new HVAC cause Lennox had a good reputation. Never again. Don't sell bad products to poor customers. I pray the Lord rights any wrong, deception, dishonesty or hiding the truth from customers. Do what is right!

I stayed in a large Airbnb which had one Mini-Split (not Lennox) and it warmed the whole area perfectly. This is why I decided to go with a Mini-Split for my home, a much smaller area. What a disaster that has been. My home is never warm enough, I have had so many technicians out trying to fix the problems from blowing cold air in the middle of winter to topping up the low levels of refrigerant in the heat pump to resealing the outside lines. This was a very expensive purchase and I rue the day I bought it. The company through Costco I would have expected to be one of the best, but I have no confidence in their technicians. This brand new system presented problems from the beginning.

In our town Lennox has limited distributors so the companies that install can charge what they want. I paid 9,350.00 plus tax for gas furnace/install, found out after the exact same one and install in bigger cities (that compete for business) cost 4,759.00. That's half the price. Companies should be regulated as to not rip people off. If Lennox did have a rebate the estimator should inform the client.

A.The iComfort S30 ultra Smart Thermostat that controls the Lennox heat pump has software that does Not leave the owner full control, to have the option to stop the thermostat to switch to gas mode, even when the settings are set for -15degC and the actual outside is warmer. B. The De-icing of the heat pump required for operation should blow the cold air to outside, instead of inside and freezing or rather cooling the air that just been warmed up. C. I would recommend this product to a friend if Lennox could fix the software to allow the owner to stop the thermostat to switch to gas when the outdoor temperature is above the high balance set point. D. Important to note that the EL18XPV Heat Pump it only operates to -17deg C

The Lennox brand is one of a premium product with a corresponding higher price. My experience with Lennox.. 5 years and 7 months ago I had a new custom home built with the highest end (at the time) "Cadillac" Lennox HVAC installed. The system has a tablet interface in the house that controls myriad zones, connected wirelessly to the furnace in the garage. The thermostat's wireless component just failed. Called Lennox and learned they've completely discontinued this "lemon" line, no replacement parts available, and they insultingly tried to upsell me to their newer wireless system. They clearly sold me a problematic product line that they divested themselves from, and now I'm stuck with an in-op heater in my new house.

I bought a new Lennox HVAC system 2 1/2 years ago, in 2 1/2 years it shouldn't need service at all! I have had to have technicians out 3 times already, at 5 years it will need to be replaced because it will be too costly to maintain! The S30 thermostat failed in the first year and was covered, now at 2 1/2 years the S30 thermostat sending unit failed, the part was under warranty but the technician was $300 because it was a holiday, new years day, Lennox should be responsible, I paid a premium price for a junk HVAC system that needs repairs every 9 months, this is ridiculous! It's garbage and should be covered because of manufacture deficiencies! A new HVAC shouldn't need service in the first 5 years and mine has needed service 3 times in 2 1/2 years!

I purchased a Lennox heat pump in February, 2024. It's now December and I have had to have the repair/installers out at least 8 times. It would work for a few weeks and then break down. Luckily it's still under warranty. The repair company is coming today and if they can't get it fixed permanently, I'm going to demand a refund and install a better system, not a Lennox. I talked to the Lennox rep and he said they would replace it free of charge, but who's to say the new one would be any better? Garbage in my opinion, buy a Mitsubishi that has a good reputation.

Junk. Don’t waste your time and money. Mine went to the junkyard in the sky after only seven years. Started leaking Freon, fixed it twice, happened a third time, wasn’t worth fixing again, I had already paid half the cost of replacing it by this point.

We purchased a Lennox HVAC system from our service provider, Midland Air in Columbia SC ten years ago! It is still under warranty but we’ve had so much trouble with the unit from day one! At least once a year there is some kind of problem! Today, Dec 21, 2024, Midland came out because we had no heat!! It was 33 degrees last night and is supposed to get down to 27 tonight! They said the blower went out and would have to get approval from Lennox and might not get it for 3-4 days! Tomorrow night is going to be 22 degrees! We are Senior citizens and need heat! No offer to get us a hotel or any heater! They left and said “Sorry for the inconvenience”. Not only does Lennox sell crap to their Reps, the Reps won’t back anything without Lennox’s approval! So I will never ever use Midland Air again and I will never ever buy Lennox again either!!!!

I have 2 Lennox Heat Pumps here in Florida. One has operated as expected. The second has had the blower motor replaced and now, after 14 months is out again. Lennox states they the blower motor is back ordered…now over 30 days. Does that mean the motor is faulty to start with or do they have an inventory problem? When seeking help from Lennox, they keep deflecting by telling me the part is warranted but not the labor. I’m okay with that, but provide me with the part, don’t make me wait for more than 30 days. Lennox response is to push their faulty part issues over on their customer and offer no support. I went so far as to write a letter to their President…no response. That speaks volumes about their customer service. Dave Lennox must be rolling over in his grave!

Bought a new house with a Lennox mini split which had been installed in summer 2019. Turned on heat in November to realize the mini split wasn't functioning well - kind of heating but not well. Turns out we have a refrigerant leak at the coil of one of our 3 heads. You will find that this is a known problem with Lennox products. They settled a class action law suit in 2015 for this exact problem but apparently didn't up their game. It cost $2000 to diagnose the problem and $2500 for a new head. Despite being 3-4 months out of warranty, Lennox decided to not do the right thing. The service tech recommended spending $15,000 to replace the whole system with a more reliable brand. Lennox does NOT manufacture its own mini splits.

Lennox is an absolute scam! I have a Lennox furnace that was purchased 5 years ago and the heat exchanger went on it and almost killed my family with the carbon monoxide leaking into the house. They DO NOT STOCK PARTS AND ONLY MANUFACTURE WHEN REQUESTED. We have placed the order of a new heat exchanger which was under warranty October 28th. It’s now December 2nd with nobody having answers on the whereabouts.. My family is still stuck in the winter with no heat and not one person cares.. Please please do yourself a favour and use another company. It’s now minus 10 degrees and we are all in sweaters and jackets to stay warm.. We are lost and have no clue what to do..

Looks like I join a group of Lenox customers that have faulty furnace/air conditioner units. So sad that the Lenox name is no longer reputable. Our unit was purchased in 2019 and two years later the troubles came. First the air conditioner (Merit Series 14ACX) acted up. Three return repair calls later it turns out faulty wiring was the cause. Warranty covered some but $400 dollars for Freon was not. Then this year the shroud had to be replaced. Unfortunately now I am sitting in a cold house on November 29th.. The furnace unit stopped working on Sunday, November 24th. The repair person for the company came out on Monday the 25th and examined the furnace unit and reported that the blower motor was shot. Warranty is still in effect but I am sure I will have more out of pocket expenses. Waiting for a replacement blower motor.

I am very disappointed. A brand new Lennox heat pump system (ML17XP1-036-230A and CBK45UHVT-036-230-0) fails to work on Day One. In particular, the air handler is inoperative. Tomorrow the installer will get the part from Lennox for the repair. I think that Lennox needs to exercise better quality control.

I will never recommend Lennox to anyone. There was a leak in the outside unit which was under warranty that caused a short circuit. That caused over $8000 dollars to the rest of our system. Lennox told us they are not responsible for damage to other equipment due to malfunction of their equipment!! That is a very poor company with quality issues. Avoid at all costs!

I live in Canada and my furnace has been shut off due to a faulty heat exchange unit for over a month! I have been working with a repair company who told me they would have the part yesterday - 2 weeks after they initially began work on my furnace. After waiting all day for the repair to happen I was told this morning that I have to wait till next Wednesday to maybe get the part! I spoke with the Lennox customer care hotline and was told in no uncertain terms that there is no guarantee that parts will be delivered in any given timeframe. His exact words were that they cannot tell me when I will get the part. Despite the fact that it is now November, and I have been living without heat in my house for over a month! Also, this furnace is less than 2 years old and I'm still under warranty. DO NOT BUY LENNOX if you have a choice, the parts will break and you will be stuck without heat and no way to fix the problem.

I just had the most expensive warranty repair bill in my life. Due to a Lennox A frame. Only two years old and my total warranty bill exceeded $1100. Yup that's right for a warranty. Never again will I buy a lennox product. Sure they cover the part but nothing else. I say their warranty is a scam and I ended to warn as many people as I can. I will continue to post my review as often as possible and on every platform as possible. Shame on you Lennox!!!!

Do NOT purchase a Lennox system. They will Not stand behind their product. I have 2 homes and a Lennox top of line system in each. 3 coil replacements and 4 Blower motors failed. Lennox refused to replace Blower motors even after failing under warranty. Made me open several customer service cases and run around. STAY FAR AWAY FROM LENNOX.

We bought our furnace in 2021. Less than 3 years in the blower motor broke. While the part was covered under warranty, over $1,000 of labour was not. My previous furnace lasted for 30+ years before being replaced. Very disappointed in the quality.

Have a 4 year old unit that has broken down 3 times per year. Every time it gets over 80* it breaks and I need to have a tech come out. The tech has been charging me for parts and refusing to go through the warranty. I called the Lennox approved techs in my area and they said that only the original installer can service it or it will void warranty. Huh? I then called Lennox customer support and they told me to pound sand. I asked for a manager and the very rude support lady hung up on me. Needless to say I will be staying away from Lennox forever.

I built a new house in 2020. We moved in November 23, 2020. September of 2024, the blower motor (in the air handler) not sounding good....HVAC tech said don't worry, should be under warranty, you will just pay for labor (kinda stinks I have to pay anything on a 3.8 yr old system). A few days later tech said sorry....no warranty, original installer never registered the unit. Called Lennox, told them I have all the paperwork when the house was built, unit installed. Lennox rep pretty much told me to pound salt....they can't control how the installer handles their business (remember, I have all the papework....nothing "shady" going on). The big question here is why is a 3.8 year old unit BREAKING ALREADY?!?! DO NOT BUY LENNOX!!!!

Bought a new build in December 2017. Coil started leaking in 2023. Now had to replace in 2024. Call Lennox to ask about warranty. They said we didn’t register it within 60 days of purchase in which our builder didn’t tell us about. I asked if there was ANYTHING I could do. They said absolutely not. Now I have to get a new unit after less than 7 years. It WILL NOT be a Lennox unit.

I never would have purchased my AC unit if I had known Lennox's reputation for selling known defective parts to their customers. They had a class action settlement in 2015 - 2016 for the same defective part that I am experiencing on the AC unit I bought in 2021. And they are refusing to pay labor to replace the defective evaporator coil. Horrible company!!! Never again will I buy anything Lennox. I would advise everyone to stay away and spend your money with a company that values its customers.

Do NOT buy Lennox. Installed high end unit in June 2017 for over $9,000. Sept. 2019 air handler coils leaked. Parts covered under warranty but paid $475 in labor. July 2022 air handler coil leaked again. Parts covered under warranty, but local parts distributor lied about availability and refused to provide a coil. District rep got involved and a coil appeared. August 2024 circuit board in condenser went bad. Parts covered under warranty but paid $750 in labor. Sept. 2024 AC stopped working again. Circuit board replaced again. A week later AC stopped working and it was diagnosed as bad condenser coil. Filed warranty claim but coil backordered for 1-2 months. I'm in south FL and it's 90+. Every time I call, or my tech calls tech support, it's over an hour on hold. I've paid over $11,000 in 7 years and have 3 years left on warranty, but will probably have to replace the system. Avoid this company at all cost.

Built a brand new house and I have been in the house under 2 years and it's a nice lovely 90 degrees here and this so called air conditioner already broke. Called the customer service and they could care less. I am not going to go on and on about their product - just know, you need to run and run far and fast away from it. TERRIBLE product and TERRIBLE customer service.

We recently replaced our HVAC units and the company we do business with carry Lennox. We bought 2 brand new high efficiency units. The larger unit started making loud noises after about 9 months. The company we do business with (Cool Air Mechanical) had replaced the unit twice and still making some abnormal noises. We are still trying to get the issue resolved and absolutely do not recommend it.

I built a home and installed a Lennox Elite HVAC central air system and a Lennox Merit 14ACX condenser 5 years and 6 months ago (you can probably see where this is going). The unit abruptly stopped cooling last night - I live in South Texas where we are expecting near 100 degree temps over the next week. An HVAC company that I know and trust diagnosed the problem (and I quote) as a "catastrophic failure" of the system not caused by wear but by faulty parts. (BTW, we have a very well insulated home so we don't abuse the system.) After waiting over an hour to talk to someone in "Consumer Affairs" he only told me what I already knew - the system is 192 days out of warranty, and there is "nothing we can do." I have been quoted by the HVAC company I trust over $8,000 to basically replace the system.

Nothing but trouble since it was installed about a year ago. I have had the company who sold it to me out about 8 times and the latest issue is that they are telling me that the heat exchanger vanes are so fine that they clog up once a month and have to be cleaned out or it overheats because the heat sink on the controller board is small and shuts down and has to be reset by a technician. I paid about 30K for this garbage unit and now I need to pay someone monthly to reset the unit during the summer and winter?... This is a lemon and needs to be replaced with a unit that isn't going to be a constant headache. Where are these cheap garbage units manufactured anyway? China or some Russian-controlled country?...

Bought a home with 2 Lennox furnaces installed 7/8/19. Bought, worked fine and turned off in March of 24. Hit summer here so just put back on yesterday 9/9/24 to find out 1 had an issue and company wanted 1556 to repair. After on hold with Lennox over 1 hr. (No exaggeration) the rep continues to tell me too bad out of the 5 year warranty. Who would have put their heat on in 90 degree weather to see if furnace worked and who would have expected a Lenox furnace to go out in 5 years after hearing their claims of how great they are. After the rep continuously telling me he would not help I asked to talk to his supervisor. Instead he gave me another # to call. After another 1/2 hr I gave up realizing Lennox actually has no customer service and little care of making exceptions. Very dissatisfied and will make sure all those in my sphere will know better than buy a Lennox.

Was on hold for 35 minutes, they then transferred me to technical support and was on hold for another 45 minutes. Ridiculous that Dave or any of his employees can't answer the phone. It's a bad sign when a company has no customer service, sort of leaves me hanging with a device that doesn't work. C'mon Dave!

Lots of people push Lennox as one of the best and most reliable brands on the market. They are all liars. I bought two of Lennox’s top-of-the-line residential units. While they work for a little while, when they go out, Dealers/Installers cannot get the parts to fix them. I have been without air conditioning for three weeks, because of a failed condenser unit cooling fan motor. My installer cannot get a replacement motor. Don’t know when it will arrive. Do your research. Go to Better Business Bureau. Look up Lennox. Don’t make the same mistake I made. Find a Manufacturer who has good support after the sale.

We built our home, and after discussing with the builder and the HVAC contractor, we decided to install 7 air handler/heat pumps and 1 mini split from Lennox. The mini split has been a problem from day one. Every year we have had an issue with it. It again stopped working this year, and leaked all over the wall. The HVAC company came out and showed me that the coil was rotten. How can a coil rot out in three years? Apparently all Lennox mini splits are made in China and they are know to have issues like this.

Our air conditioner was only 3 years old. The blower motor went out and Lennox informed our repair company that the warrantied motor was out of stock. I called Lennox directly and was also told the motor was backordered. It could be up to 4 weeks or more before the part could be produced. I explained we live in Arizona. Our house is at 92 degrees. We can't possibly live here for 4 weeks or more. We are retired and it is ridiculous we have to even pay $700 in labor for a broken motor on A/C unit that is only 3 yrs old. Then for Lennox to not keep a warrantied part in stock is outrageous. I was informed there was nothing they would do for us.

Never ever buy Lennox products. I have 4 Lennox units each has the iComfort thermostat. All of the thermostats have went out. The replacement runs about $1600 parts and labor. You can not use any other smart thermostat. Lennox has made their system uncompilable to force you to use their products. I did have my HVAC technician replace one unit with a Sensi thermostat but I did lose some of the functionality. Meanwhile the house I grew up in still rocking the original thermostat 40 years later. When these units fail I will replace with anything other than lennox.

### Lennox Air Conditioner Review. My experience with Lennox air conditioners has been nothing short of a nightmare. First, my blower fan and circuit board failed, which should have been a simple fix. However, despite these parts being under warranty, they were on backorder, leaving me to endure 100-degree temperatures for a grueling 10 days. This kind of service delay is utterly unacceptable and shows a blatant disregard for customer comfort and safety.

I installed Lennox 3 tone unit less than 5 years ago and the compressor licked for a 2nd time until in warranty. The first time was after only 2 years of use. It took Lennox and the local dealer about 2 months to replace it under the warranty. Less than 2 year now it broke again. It's been already 2 weeks waiting to get it fixed.. Lennox customer affairs service in practically non existing. The general phone information told me to call customer affairs in regular business hour 9 am to 5 pm CST at 972-497-5799. I called and I I’ve been waiting for 1 hour and 30 minutes for a rep to answer. The only thing he was able to do is to say he will follow up with the warranty department. He blamed the dealer for the delays and the dealer is pointing the finger to the manufacturer.

Bought and set up install contract through Costco. Contract is 10 year parts/labour + 12 year on compressor. These specs were the deciding factors. Last year we had to replace the blower motors already on the 2 int units. Lennox dropped us through the cracks and couldn't find a local dealer to help. Lennox didn't even have the capacity to read the signed contract and acknowledge we were still under warranty. Costco.ca on the other hand, stood by their product and found a contractor that would service the equipment. Lennox NO. Costco.ca YES.

I purchased a Lennox 2-ton gas-pack unit on 28 May 2015. It was recommended by a local Service expert company. The unit replaced a 12-year-old 3-ton unit of a different manufacture. Which, replaced a 17-year-old 3-ton unit of the same manufacture. I was told my ductwork was too small for a 3-ton unit at a 1200 sq ft home. The new Lennox unit never kept up in cooling. 91 degrees outside temperature at noon and thermostat set 77, the unit would shut off while still receiving the signal from the thermostat. After any where’s between 10 to 20 minutes, it starts up then cuts back off. House temp climbs up to 89 degrees+ Humidity rises also. Symptoms persist during night time temperatures in the 70's. There's no particular time when it will continue to cycle like that.

Please stay clear. Do not buy. You will only get 2 to 3 years out of it. Read the fine prints on the warranty. When something happens and you call them, they will tell you that it is not covered under the warranty. Coil issue is not covered. A lot of issue is not covered. The older house we got had Trane AC and it lasted 11 years before we had any issue. Please stay clear. We are having to pay $3000 out of our own pocket to pay for one repair.

Lennox thermostats are a complete disaster. I’ve had multiple models and many replacements. They do not stand behind their product. Do not buy a Lennox system. I am switching to Ecobee at my expense and will never buy anything lennox again.

We bought a Lennox heat pump with the thought it was good, quiet, and efficient but none of them are true. We spent almost twice as much as other and it is just installed and Nest tell me it will take 30 minutes to reach 74 degrees…It is loud, and 30 minutes to reach 74 degrees seriously?? We have energy efficient windows and doors so it is not that -still running and has not shut off since it was installed- DO NOT BUY LENNOX.

My Lennox unit was between 5 and 8 years old when it had to be entirely replaced - the leaky evaporator coil was the final blow. My inspection report showed that the unit was five years old, but Lennox claimed it was eight. They would not honor the 10 year warranty because I was not the original homeowner. I had sunk hundreds of dollars per year in that unit because of one problem or another; not cooling, a part had burned out and had to be replaced-(that was scary!-it looked like it had actually burnt in a fire!-and I’m glad it’s gone.

I have a Lennox 20 seer heat pump. The previous homeowner installed the unit 4 years prior to me purchasing this house. I called Lennox, they said the unit has a 10 year warranty, but the warranty is reduced to 5 years if you’re the second home owner. This is total nonsense! Lennox will make up any reason to not warranty their junk products. My unit is now 6 years old and it has a bad condenser motor and leaking evaporator coils. I am spending a little over $3,000 to repair this junk Lennox unit that is supposed to be top tier and only 6 years old.

We built our house in 2016 and the builder was a higher end builder. We sat down with the company that does the HVAC and built what we thought was a great system for our needs. Problems with the Lennox system and coil started the first year. First of all the lawsuit had already been going on! Why would you even put a Lennox or suggest one for our house! I want to Sue the Builder, The HVAC company and Lennox. We have replaced the Coil several times and the UV light we can't even use. They send out different repairmen every time that gives us new information each time. Our Dampers are no use anymore. We just spent $1500 in labor 3 months ago to replace the Coil AGAIN!!!! Because Lennox won't pay for labor anymore. REALLY! 3 weeks later all the coolant leaked out, but nobody can figure out why???

We live in Trenton Ontario Canada. We had a heat pump put in by Quinte Air Supply from our area. Within a month it was leaking, which they did come out and clear the lines. Again we had another leak during the pandemic and really don't remember how many times we called but they wouldn't return our calls. We had to contact Lennox directly and funny they came within I believe it was a day. He was rude, had no concern that my wood floors were destroyed. They talked us into this larger piece of junk and said it would work. One of the techs told us it's not a matter of if but when it will leak... Really. Every single year it leaks even though we have it serviced regularly. My floors, wall, buffet and a bookcase my late father are all damaged. Buyer Beware!!!!

Sadly my experience with Lennox customer service has been a very bad experience!! They do not want to speak with anyone unless they are a dealer!! This is horrible customer service!! We have a furnace, thankfully not their a/c until. Last year after only 6 years the thermostat went, a new one cost us $1500 dollars, being a dual furnace we could not go with another brand. That thermostat is now glitching and blacking out! Also the GF switch keeps giving an error. My technician has been trying to reach them, keeps getting a message about a high call volume and disconnected. No option for a message!! She is also trying to get the GF switch replaced under warranty but again can’t get anyone to answer!! Super frustrating situation. For the above reason I would NEVER recommend this company!!

I purchased a Lennox unit for my new home a year and half ago, last month the control panel “circuit board” went out leaving us without AC in Texas for 3 days. Now a month later the blower motor has gone out, it has been a week since repair tech was out here. I was informed today the part is also on backorder and will take about a month to come in. Really? It’s 96* outside and 86 in my house. I shouldn’t even be having to call a repair tech for a unit that’s only a year and half old. Ridiculous… I don’t recommend nor would I EVER purchase a Lennox AC.

Two parts failures in 18 months on an Elite HVAC heat pump system - First HZ322 circuit board (8 months) and just in May the Shroeder intake valve failed -- which then requiring 5 lbs R410A ($500) recharge NOT covered by warranty. Plus service charge after one year. Never had any problems with my previous TRANE. Poor quality. Do not recommend.

We are sadden to know that the unit we got is constantly breaking down. Thank gosh for the company Norco in Spokane for helping us each any way they can. They have taken a terrific loss in fixing a unit that is a lemon. Hours for fixing the Heat Pump (3) times, the heat pump was vibrated loose from the unit and had to be fixed. (This was caused by manufacture not tightening the bolts and nuts down.) The Thermostat is not working properly and has to be replaced but that is $1,100.00 what a rip off. The company came to our home 3 times to try to fix the thermostat but until we get the money we can use it but has to be programed in each time there is a outage. I hope Norco goes after this company in a lawsuit so they can recoup their losses from each customer who bought this unit.

Have two top of the line Lennox Heat Pumps. Approaching 7 years in age. Fortunately I bought a 5 year complete warranty. During the first 5 years thousands of dollars of repairs were performed. 3 iComfort thermostat replaced, two circuit boards, fan and other service calls. Just paid out over 1,440.00 to replace reversing valve on one unit. Part still under warranty so no cost. 1,400 was for 3 hours labor and 9 lbs of refrigerant. When I replace these units they will not be Lennox’s. They were expensive to purchase and install and have been by far the most to maintain, over the routine maintenance contract that I have paid monthly since they were purchased. I am now a “never Lenox”!

Bought a new Lennox furnace and air conditioning unit. Furnace is 80% efficiency and has been fine. The air conditioning unit had the motor seize within the first 10 uses. It was replaced for free. Tried to use it for the first time this year and it is seized again. They are replacing for free again. 2 years, 2 motor replacements on the air conditioning unit.

Moved into our new custom built home in 2022. We have 2 Lennox units for our HVAC system. Unfortunately, we have had nothing but problems with our Lennox products. One unit had electrical problems causing the unit to “short out”. This was an initial installer problem, however within a couple months of usage, the fan blade had to be replaced as it was warped causing extremely loud audible sounds even impacting our neighbors. Our second unit has been the main issue. We have had continuing issues with the AC experience since inception. The coil started leaking and releasing coolant within 8 months and then it failed again in the 17th month. It is now 2 years since we have had Lennox products and we now have another coil leak, Yes, another leak resulting in our “third” coil leak and need for replacement all in a 2 year period.

The internal coil on my Lennox AC unit was defective and had been the subject of a class action law suit against the company. When I contacted to the Lennox Consumer Affairs Department about the issue, they refused to cover any of the cost of the $3,000 repair, not even the cost of their defective part. I would not recommend Lennox products.

Overpriced junk!!! Lennox makes the worst AC unit out there. I’ve had multiple houses with different AC systems and never had this issue unless they were 20 years old. My house now had 2 Lennox units. Replaced one at 5 1/2 years and now having a replace the other one at 7 years. I was the second owner on this house so they reduced the 10 year warranty down to five so they can cheat you out of the warranty and never paid for nothing. Customer service was terrible and they would not help you with anything. The consumer affairs department was a joke. They do not care about you or the money you’ve wasted on their units.

The Lennox gear installed in my Drees home in 2019 has failed twice. The compressor failed after a year and it cost me outrageous labor but at least they covered the part. In 2023, the evaporator coil failed. Lennox could not provide a replacement part. Their warranty service, customer service, and consumer affairs departments were totally worthless. We spent thousands to buy a compatible replacement part from Carrier via our contractor that is also a Lennox dealer. They said this is a problem they see all the time with Lennox. We hired an attorney and wrote a demand letter for reimbursement after being ignored by Lennox. To date, 8 month later, we have heard absolutely nothing from Lennox. We filed a lawsuit against them today.

Great...when it works. Have had a top of the line Lennox Heat Pump (top of the line in 2015) for 10 years. Unit & Installation cost me just under $8,000 10 years ago. I have spent over $8,000 in service call and labor charges over the past 10 years on the unit. Parts have been covered under the 10 year Lennox Warranty. The original evaporator coil has been replaced twice. I'm on the 3rd iComfort thermostat. I have had yearly service calls for when the unit just stops working (in addition to the annual routine maintenance calls). Too many "communication" errors to mention. The air handler, outside unit and thermostat must communicate correctly in order for the system to work.

I bought my home new in 2020. I have a Lennox unit outside and in my attic. I haven't had NOTHING but problems out this raggedy unit ever since I moved in. EVERY single year I have had a problem. And this year is not different. They drained it. They put coolant in it just last year. The thermostat was set wrong. They left the filter in the upstairs unit until one of the many people I had fix it over the years realized it. The relay sensor went bad. And all of this in 4 years. My warranty hasn't paid for crap.

Last summer my house A/C was not cooling enough as the summer got hotter, with some help from a friend that we concluded it need more coolant, I picked the A/C Handyman from Lennox got my A/C running cool again for a very reasonable price and gave me a lots of valuable lessons on how to maintain my A/C system.

We purchased a Lennox residential mini-split system for our home in 2021. It was professionally installed by an authorized Lennox dealer, who has since left town and no longer supports warranty claims. The unit has been non-functional for over 8 months now, and while we are working with another dealer, willing to help us out with this warranty work, they cannot get support or parts from Lennox either. Less than 3 years into a 5 year warranty and our system is dead, no idea when parts will be made available and no one at Lennox is willing to step up and support the work. DO NOT BUY LENNOX as they cannot stand behind their products, their dealers or their warranties.

Purchased a new AC GAS package combination LRP16GX48-108VP-3 in 03/2021. Heat blows for five minutes shuts off as the mother (circuit) board has an error code. No parts available still in 2024 and is still on back order and no idea when it’s coming in. It’s been two years now. Awful. The circuit board is bad and called Lennox headquarters and of course no help and doesn’t have any idea when the parts will be available nor can answer any questions. Terrible company that makes products that can’t be fixed since they don’t have parts. I would not recommend buying a Lennox brand just based on the time and aggravation of dealing with their faulty products and representatives who are not helpful. Just not worth it.

I purchased a Lennox top of the line 21 SEER 3 ton heat pump 10 years ago. Besides the purchase, I have spent over $6,000 in labor cost to replace the coils, the compressor and various other parts on the machine. This unit is a disgrace!! I would never purchase a Lennox again. While Lennox's warranty pays for the parts for 10 years, labor cost are exorbitant. I'm moving on with a different manufacturer and hoping for the best.

Our furnace stopped working on a cold day, so I called the HVAC contactor that installed the unit during new construction 18 months ago. The service tech found that a pressure switch wire had disconnected and wrapped around the inducer motor. When asked how that could happen when the unit has never been opened or serviced, I was told that the only explanation was "poor workmanship" at the point of assembly. The wire was reconnected, and I paid the $225 service call. I contacted Lennox several times by email and phone about splitting the cost of repair only to receive the run around and finally a denial based on a warranty technicality argument. I now will pursue small claims court action with the support of the installation contractor. Junk product, fake customer service!

This happened despite the thermostat remaining on heat. It became cold so quickly and frequently that I got up from bed to switch to emergency heat w/o heat pump. Twice I had the COSTCO contractor visit since the pump was under the 12 month warranty. Neither time did they diagnose the problem. The first tech found that the new air handler had been incorrectly set for a 5 ton Heat Pump. My Lennox is a 3 ton. Researching online I saw that a faulty reversing valve could misdirect heated or cooled air if stuck.

9 years ago I bought one 5 ton Lennox unit for 9,000 (thousand) on Costco. On this 9 years I spend 9,000 (thousand) more to fix on warranty and now broke and nobody knows to fix the unit and no one Costco and Lennox help me to fixed it.

I purchased a complete Lennox heat pump air conditioner system. When they installed the valve was bad, 1 1/2 later the compressor and two other parts went bad. Because it was over a year old, I had to pay for labor and freon 1,465.00. I contact Lennox about this. I don't feel it's fair that something this new should have to be repaired. They had me scan and send them everything from the maintenance and repairs, only to say, "We can't help you. We only cover parts." DO NOT BUY A LENNOX. THEY ARE JUNK PLUS THEIR CUSTOMER SERVICES IS BAD. They didn't even replace the unit, just the parts that were bad. It would have been cheaper on labor for me if they replaced the whole unit. I was told, "I'm so sorry but we only replace the broken parts."

I think the overall HVAC system of Lennox is solid, we've had good luck with our high end HVAC system for the first 7 years, except for the controller. The controller is not easily replaced it was a 10F81 that went obsolete shortly after we purchased the system. Even changing to the replacement from Lennox required specialized wiring...and no guarantee that they'd do the same thing later. So my Lennox dealer suggested he do rewiring and use a real controller (Ecobee). I'd lose some of the energy efficiency but I would rest assured that obsolescence would not happen again (and the controller and work was less than $500 - 1/3 of the cost to upgrade to another junk Lennox controller). It works great and actually kept my house warmer (albeit maybe not as energy efficient).

We bought a home with a Lennox AC that still had warranty on it. After the extreme heatwave the compressor went out in September. The service technician submitted a request to receive a replacement part as the AC was under warranty. Delivery time was supposedly 6-8 weeks. In November our technician asked for an update and Lennox claimed that he never submitted a request. The technician stood his ground but now it's January and Lennox have still not resolved the issue. Our technician says this is typical of how Lennox treat customers and technicians. And good luck getting hold of customer service. No wonder, they're probably overrun by frustrated customers.

I bought a Lennox G61V high efficiency two-stage furnace in February 2012. I had a service technician inspect it annually as per the warranty. Within one year hoses needed to be replaced as it was leaking. In 2014 gas valve and inducer needed replacement. In 2015 the drain hose was replaced and more leaking. In 2018 the collector box needed replacement - I had to pay for this. Now on November 6 2023, the motor had to be replaced and the warranty stopped in February 2022. I called Lennox and reported these details. They said nothing they can do because no warranty. Very poor quality.

I bought 2 Lennox central air conditioners/heat pumps through Costco in January, 2022. In 18 months, we have needed repairs 3 times. The most recent, in August,2023 is due to a coiling coil leak. The repair person indicated that the coil needed to be replaced. Lennox indicated that the replacement part is out of stock and should be available in 6-8 weeks. It is now December and Lennox will give no update on the status of the part replacement. While the replacement part should be covered by warranty (like the 2 other part replacements that were needed), the recharge of the system will cost $1800. Avoid Lennox. I have never had such poor service.

I bought my Lennox HVAC system in 2019 for $13,000. It has held up as fair as moving air is concerned though it constantly has trouble staying connected to the internet even with a line of site short distance to the Wi-Fi router. This year I replaced the router and now the Lennox system doesn’t even see any networks. There’s no way to reboot the system and the Lennox dealer said they’d be happy to look at it for $130/hour. This was a complete rip off as far as the thermostat is concerned. It really should have worked properly from the start. Choose another company that will stand by their product and fix it when it doesn’t work. They wouldn’t even try to help me out on the phone.

6 months after I got my system installed I lost power. Tech came out and had to replace a hub (major part). 1 month later I had to turn my furnace on. Now I am getting codes, my furnace turns off for an hour or so every 2 hours to cool down. Repair men have been out 6 times in a month. I was getting emails to tell me when the furnace was having an error code but it decided to stop sending these. I called Lennox, was escalated to tier 2 for IT. On hold for over an hour. Dominic spoke with IT and supposedly they would call me when they knew what the problem was. I asked to speak with a manager that was there, (he said there was someone) and was transferred to Maria. And instantly got voicemail. So shockingly 24 hours later and have not heard back from either the IT dept. or Maria. Yet again they are trying to fix my furnace today. I strongly recommend that you stay away from lennox. I'll be paying for this mistake for the next 10 years.

Lennox iComfort thermostat died immediately after warranty expired. From researching on the internet, this has happened to other people and not just with this particular product/model either. Called Lennox and was put on hold for 40 minutes before ultimately hanging up. Very poor customer service and it seems that they have built in obsolescence into their products just past the warranty period.

I got a new Lennox HVAC installed in Aug 2016. The thermostat screen went blue and doesn't work anymore. In looking online, everyone is struggling with this issue just after the 5 year warranty for the iComfort wifi thermostat (Lennox's own thermostat). Lennox told me, "Tough luck as out of warranty" yet everyone had the same issue. The new thermostat is $800!

Purchased a ML195DF Furnace. After 6 years the blower motor would get hot causing it to stop while running. This in turn would cause a minor explosions making loud banging noises. The Furnace turns out has a 5 year warranty for the Merit series. The cost to replace the small motor assembly is about 1300.00 plus 300.00 to 400.00 labor. Not only does it seem to be a safety issue and not stand by it, they charge an enormously inflated price for a small motor. I would not recommend purchasing a Lennox unit based on my experience.

Purchased a Lennox system and thought I was buying a quality system. After 6 years the system nearly caught fire. Wiring harness was routed laying on the charge line during the manufacturing process. Contacted Lennox numerous times and went days and sometimes a week or more with no response or help during August which is extremely hot. They tried to put it back on me numerous times saying I did not provide maintenance receipts. I do all my maintenance which is within my right and I do it every 6 months. This issue is not a maintenance item. You would expect to disassemble an outside AC unit to inspect wiring routing. I don’t ever recall seeing that in automotive repair manuals to disassemble a car to inspect the wiring. I have been in the Aviation and Automotive maintenance business for 30 years. If I could give Lennox ZERO STARS I WOULD.

I had an 11 year old Carrier system that was installed and maintained by a local company called Del-Air. After having two sequential service calls to replace the blower motor, the HVAC company heavily promoted replacing it with a Lennox system. I spent $10K on the new system which was supposed to be ultra efficient. The installation went badly and the system would not pass inspection. After roughly a dozen attempts to repair it and no follow-up from the HVAC company, I finally engaged Lennox itself as I was concerned with the physical damage they had done to my air handler as well as modifications that were counter-indicated by the installation guide. Lennox refuses to stand behind their product or dealer. They won't even provide a tube of touch-up paint to address some of the damage to the air handler that their dealer did, so now my $10K system is left to rot in my humid, Florida garage.

In June of 2021 I paid 7K for a new system. In the last few months the inside coils, outside coils, compressor, and thermostat all required replacement. Warranty covers parts but not labor. Thermostat was out of warranty. In my opinion and experience avoid Lennox branded items as they are not made with quality but at a premium price. The labor for repairs plus a new thermostat was nearly 3K. I wouldn't recommend anyone purchase anything Lennox brand. While a warranty is nice, it shouldn't be necessary especially in a unit so young.

1 1/2 year old Lennox 16 Seer Air Conditioner has a leak in the coil. Lennox wanted our AC company to “repair” it at cost of $1600 and no warranty. AC company said another leak was bound to happen. Lennox would not call us back for over a week (imagine a week in 90 degree + weather). We finally put in another company’s product and are continuing to try to talk to Lennox - 1.5 weeks and counting.

I purchased the XP20 heat pump in October 2016 with the iComfort thermostat. This year, the iComfort thermostat went blank and the app stopped working on my phone. Replacing the thermostat cost $1123. During the replacement, the fan motor failed, it was working just fine until then. That cost another $2237. Neither the thermostat nor the fan motor had any cheaper after market options as Lennox equipment is proprietary. I have put heat pumps, not Lennox, in three other homes with repair costs less than $500. The replacement cost of the thermostat and fan motor is incredibly too high. I would not recommend Lennox.

I bought 3 units only 4 months ago and already having problems. It’s was way to easy for them to stop working then it would work then stop. Don’t waste your money. 5k for one unit is far too much for these problems.

We built a new house in 2017, with it, we opted for efficient everything… Year 2 had to get Freon put it, it was almost out. Year 7 coils out completely, no warranty, no nothing… Parts are terrible to get. Ended up replacing the entire system with another brand.

Bought new Lennox furnace, AC Unit, air Cleaner and humidity control in 2018. Told salesman our current system at that time was a Goodman and it lasted from 1978 until 2018 when we replaced before retirement. We wanted a new reliable system. A week ago I woke up to a 411 error code on thermostat and could not clear it. The unit outside showed code 1 and 4. Called the installer to come out and told them error codes. I was told a $95 labor fee (labor not covered under warranty). Tech got here asked what codes and told us probably a freon leak. Would have to run a dye through system to find where leaking. That test not covered. $600 cost just to test. I was livid.

NEVER BUY A LENNOX. After installing a CX20 system in 2015 we've had to replace the Thermostat, the fan, and now the evaporator coils. Just go to Home Depot and buy window units. Save the headache and the money. The response from Lennox was sympathy. They were very sorry their products keep breaking and I had to pay thousands of dollars in labor costs to replace parts under warranty. Do your research and buy something else. Lennox manufactures subpar products.

Our Lennox AC unit on our new home in Naples Fl was less than 5 years old when the evaporator coil failed on 6/14/23. Our contractor finally received the replacement part 8/18/23. Repair bill was $1800 for labor and refrigerant - even though the part was covered under warranty. If you want to have no AC during a hot, humid summer and a system that doesn't last- buy a Lennox. Every AC contractor I've spoken with says they are the worst and recommend Carrier.

Purchase my home in 2021 which was built in 2015. Previous homeowner had one of the two AC evaporators replaced under the Lennox class action suit. It failed within a year of being replaced. The second unit failed this week due to massive leaks. Both units are less than 8 years old. Was quoted $4k just to recharge the systems in order to find and repair the leaks. No thanks! Done with Lennox! Will never buy one nor recommend them to anybody. $26k later and I have two brand new York inverter heat pumps with 10 years parts and service warranty. Want to get screwed over? Purchase a Lennox.

Six years ago I bought a home in Florida. I was pleased at that time to know it had a new Lennox AC unit. Three years ago the unit failed. My local Lennox dealer came out and had to replace the evaporator coil. They had a big fight at that time to replace that and the blower motor under warranty, Lennox finally gave in and shipped the parts. I was still very unhappy because I still had to pay $1450 for labor to replace warrantied parts. So jump forward three years. Now the three year old blower motor failed again. After two weeks of not having AC in 95 degree weather, Lennox declined to warranty a three year old part, so now I have another huge bill to pay for my piece of junk ac unit from Lennox. Product is one thing, customer service is another and Lennox failed miserably on both issues.

I bought a 20 year old house in 2019 with a patched together AC system so I replaced it with Costco's Lennox product via a local contractor. It cost me roughly $12,000. Up until about 4 weeks ago the system had been running beautifully (had it four years). It suddenly couldn't keep up with the heat. The findings: the coil is leaking. It lost 5lbs + of refrigerant. Guess what? The warranty for parts is 10 years but doesn't cover labor and refrigerant replacement. After spending $3700 to find and refill the refrigerant -- I could have bought a brand new unit -- a Goodman, Trane or any other name brand for much less money.

After I filed a complaint with the BBB, the Local Lennox dealer received the needed parts. And repaired the whole unit. It was down for approximately one month.

Always very helpful with what our company needs and very quickly on searching for products and delivering our orders. I really recommend this branch to all the HVAC needs in the area of Houston Texas.

I have Lennox units. The upstairs unit was replaced in June 2021 and downstairs in April of 2022. In August of 2023 I have racked up over $3,000 in labor costs for repairs on over 12,000 worth of AC units. Lennox is a rip off that sticks it to you when you buy, only to set you up for years of paying them for their terrible parts. I have owned several houses with the cheap brands and have never had trouble like this. My unit at my old house was 21 years old and still worked when I sold the house.

We have 2 combined units with Heat Pump and Cooling. Every year we are having to replace parts and get them repaired. We just got told today that the latest issue was going to cost $900 for a part to repair the AC. I don't know any of my friends or neighbors that have this issue with their HVAC. Last week we had to have the other unit fixed. Some of it was covered by parts warranty but we still had to pay about $700 for stuff that wasn't such as more coolant. How does my Car's A/C go 7 years without any failures while it is flying down rough roads but a unit that doesn't move is constantly breaking down? Don't buy Lennox.

A Lennox 4 ton central HVAC system was installed in my new house in February, 2019. Four years & 4 months later the evaporator coil failed; a leak. The good news is that the coil was still in warranty (5 years). The bad news is that it cost me $2,200 for labor to replace it. And the new coil comes with only a 1 year warranty, so this could happen again & the cost of the new coil would be on me! This is totally unacceptable & needs to be investigated again. I strongly recommend that Lennox central HVAC systems NOT be a choice.

We brought a brand new AC unit June 6th 2023 end to end from Lennox and got it installed. Register the unit with Lennox for 7 years parts and 3 years labor. The AC compressor locked and failed to start within 2 weeks of installation and after a day it started on its own. Then on July 5th it completely shut down. I was desperately trying to get help from Lennox to replace the unit under warranty and lemon laws but they don't even care and has done nothing.

Our new unit was installed ~May 1. Works fine, but despite a written offer of a copy of the warranty, and despite numerous phone requests, I do not have a warranty for this expensive equipment. As an alternative, I turned to their website. There is a multitude of warranties, but the information I have (model number) does not permit me to know which one applies. BAD CUSTOMER SERVICE. WORRISOME.

This is week three and our 3 year old Lennox air conditioner is still not working. The condenser coil blew (again on a relatively new unit). I have spoken to customer service, have a case number and the management has not called me back. I spent three hours on the phone on hold as well. The customer service reps were very respectful and understanding but there was little they could do and upper management has still not responded. It is 103 degrees in Houston. I will never, ever purchase any Lennox product and I will tell anyone, anywhere, anytime, my unfortunate experience with this company.

Updated on 02/18/2024: This is a follow-up to my first review. Mid-January 2024 I noticed that snow had gathered on the fan blades of the outside unit of the heat pump which indicated to me that the unit wasn't operating. I sent an email to Ronk Brothers advising them of this and they sent out a tech. He found that the part that had been installed on 5/11/2023 had not only failed internally but had split a soldered joint and the freon had escaped. Thanks to this my recent electric bill was abnormally high as was the energy usage. I'll have to wait till I get my next electric bill to calculate the grand total of the financial hit I’ve incurred due to this failure. Then I will contact Lennox regarding compensation. Thankfully there was no charge for this repair.

I have 2 Lennox XP25 Heat Pumps. They were suppose to be the top of the line. They fail quite regularly. Each has had a variable fan motor changed, one 2 times. One is leaking some coolant now. They are 5 to 7 years old. I would not recommend the Lennox brand for any heat pump. When these die, I will never replace them with Lennox and I will always tell my horror stories to anyone. Just tonight another failure....who would have thought. Shame on me if I ever purchase one of their units. I would refuse even if it was gifted for free. The repairs are enormous in cost. I am surprised that they are still in business. Maybe they will get bought by a foreign company who can put quality in their product.

Had this dehumidifier installed as it was the choice of the hvac company we were using. We have had it for a little over a year now and it has been broken more than it has worked. We have had to have the hvac company out probably 30 times to fix various parts and reconfigure the setup to try to make it actually work. It actually raises the humidity in our house when it is on. My electric bill is thru the roof due to it running constantly. I wish we had never even had it installed. The small dehumidifier we have that is 10% of the price of this works far superior to this thing. I wrote to Lennox consumer affairs and the responses they sent were rude and dismissive. They told me they only deal with the hvac companies that install them and not the customer that actually pays for the hunk of junk. Do not buy from Lennox. Ever. I learned my lesson and will warn everyone not to make my mistake.

Purchased a Lennox HVAC system in 2012 for the upstairs of my home. Nothing but problems over its life history, some issues were covered under warranty but most were not covered. HVAC specialist replaced the coils after the warranty had expired and now I am being told that the coils are bad again (over $3K to repair), NO WAY! Spent the money to replace the entire system with another brand that uses aluminum coils. I will never buy another Lennox product. I read reviews about Lennox that say they are a top-rated brand, but that rating is for a brand new product and never a review for long-term ownership. Buyer beware!

I had a brand new system install with new built home and I had to call for a service over 7 times within 2 years starting after a week from moving in with fan motor then Freon leaking then power surge issue from outside unit then Freon leaking again. So messy system. Do not pay a penny on it.

I purchased a complete system through Costco in November of 2015. This included a central air conditioner with an air handler in the attic a high efficiency water boiler and a hot water heater. I replaced a Trane air conditioner that had given us no problems for 21 years with the new Lennox AC unit. After 4.2 years of service we had to add 2 lb of refrigerant due to what I was told was a small leak. We went to turn on the AC for the first time this season and got no cooling whatsoever. A technician came out and said we need an entirely new evaporator coil since it was leaking oil and showed signs of corrosion. After doing some research I saw that Lennox had a class action suit against them for this issue.

In 2017 I had a Lennox system installed in my house. I used a company called ACE in Fairfax, VA. The specifics on the a/c system are here: Installed 11/30/2017. LENNOX HEAT PUMP (Out Door Unit) Model 14HPX-030-230-21 Serial # 1917K29252, LENNOX AIR HANDLER Model CBX25UH-030-230-10 Serial 1717L14293, LENNOX ELECTRIC HEAT KIT Model ECB25-12.5CB-P Serial 3017D02647.

Unfortunately, I can not say anything good about the Lennox Heat Pump and Lennox Air Handler, purchased through Costco in 2016. The first system failed after 1 year, the second one "upgraded system failed after 41/2 years. Important internal part-reversing valve-developed a leak, which drained the refrigerant. Our Heat Pump became totaly useless.

We replaced our old Coleman heat pump with this absolute junk from Lennox in 2018. Our Coleman was trouble free for 18 years! The Lennox, at two weeks in, we had every tech from the installer at our place, plus a special visit from some Lennox person himself. Since then, we've had to have it worked on pretty much at every change of season as it does like today - 80 degrees out, it has failed to cool at all. Not like it is an extreme, but to Lennox, if it isn't 50 degrees out, do not expect cooling or heating. I could do better with a block of ice and a fan. It has gotten ludicrous, the number of times the installers have come out. They don't even charge us half the time, they are so embarrassed about all the issues we've had.

Contacted Lennox for about a month by email for the rebates. They never reply back. Waste of time and money. The dealer was no help either. Should of went with another system. Oh well maybe next time lol.

I'll keep it short, crappy product died in 2 (yes TWO) years lol. Lennox replaced all the crappy parts cause warranty, but I am on the hook for the thousands in labor. Lennox said sorry, not sorry, have fun! All I wanted was something small like a jelly of the month subscription

We bought a new construction house in 2020. We were given a Lennox HVAC, which started off great, really silent and run great. It is just 2023 and it makes so much noise + the temperature I set doesn’t drop but increases. It is on 24/7 but does not cool. Living in California, I am trying to figure out and call as I assume it should be under warranty, but customer service is really bad, no help everyone is expecting to pay for labor cost. Basically spending $$$$ and this is the result in 2 years, as the company claims that they run great for 10-20 years. I am so disappointed, will never shop this brand ever again.

Well, looks like Lennox is at it again. They had a class action law suit about this 2007-2015. Began paying out in 2017. We had biannual check up last week. We haven't use air since last fall. We have gas pack unit on the roof. The tech spotted telltale oil dips and checked unit, discovered leaky evaporator coil. He said that they and other Lennox dealers in the area have had more leaky evaporator coils in relatively new units than there should be. He said when parts aren't available before the cooling season has even started and there are fairly long waits as well, that is frequently an indication that there is a problem with certain units that have defective parts.

We have a two year old AC unit from Lennox Heating and Cooling. We have been facing issues one after another. Now out evaporator coil is out (had seven leaks) and Lennox is now telling us that the part is out of stock (hilarious) and that they don't have an ETA. Our tenants have been without AC for a week and I'm furious. Lennox is the worst company to deal with, every review I read shows that. Never again! Save your money please, you'll regret it.

I have a Lennox system about 3 year old. Furnace broke down in extreme cold situation and the installer told us they contacted lennox for a part about 4 weeks ago. The part is still said to be back order..what good is the system when no one can help you when you need them most and your family is suffering. 4 weeks and counting....let's say I lost complete trust in lennox.

The Lennox HVAC in my attic has developed a coil leak after just over 2 years of living in the home. Andy **, the contractor, installed and maintains the unit. Moreover, they registered my product, which I am not able to register. Only 6 months after the labor warranty has expired, the coil on the unit has developed a leak, requiring them to replace the coil at a cost of $1783.67. I find this to be outrageous. Lennox units have had previous problems with coil leaks. This is a known problem. Why is the company continuing to make products that don't last and cost people money? Andy ** states the part is under warranty, but I have to pay for the labor and Freon. They state that Freon is over 300.00 a pound. This is completely outrageous.

I installed a Lennox air conditioner a little over a year ago, but the compressor has now failed. Even though this unit is under warranty, and still manufactured, it will take 5-6 weeks to get a replacement. I live in Miami, and the temperature is in the mid to upper 80's. This is very poor product service from Lennox, leaving their customer hot and uncomfortable. Lennox should support the products they sell.

Was convinced to purchase Lennox air system by Eco-Air. Costly system but when it is working does great job. Unfortunately after having system a little over two year it has shut down four times all due to defective parts and the way it was built. The latest being a burnt out transformer due to wires shorting in panel on air pump. Thus needless to say over $700 in labor costs in this short time. Not right that because of their ill manufacturing the customer takes the burn.

My AC unit and furnace have now blown at only 4 yrs old. They have a great warranty so I wasn't too concerned, but it has now been over a month and my system is still not able to be fixed due to lack of parts available. I called Lennox directly because I didn't trust that my service provider was doing everything possible to get things moving faster and Lennox did nothing to help! Not the Lennox customer service reps fault, she was very friendly and wanted to help, there was just nothing that she could do. This company should be jumping to ensure that my unit is back up and running immediately, overnighting parts as far as I'm concerned, but that couldn't be farther from what I am experiencing. I regret going with a Lennox!

The compressor went out on my Lennox unit after just 5 years. Under their warranty, it is still going to cost more than $3,000.00 to repair. Look elsewhere. Lennox brand sucks. I wish I had purchased a brand that stands behind their product.

New construction home. Lennox Elite Series HVAC system installed. Today I had a Lennox premier service company tell me my compressor is shot and needs to be replaced. I spoke to Jacob in Consumer support and was informed that I should be happy that Lennox is providing me a new compressor. The problem is the installation and new Freon will be over $1000.00. My house is 13 months old. Do not buy Lennox! I never had a problem with my previous homes with HVAC issues in the first 5 years. DO NOT BUY LENNOX!

Less than 2 year old Merit Series ML14XP1 Heat Pump -> 3 x Failures in < 2 years = no heat in winter! Internal wiring of unit rubs against sheet metal causing shorts, each failure in a new location. Service technicians say this is a common failure: Wire is not well protected from factory. Product failure is not covered by warranty or extended warranty resulting in $355 CAD/emergency call labor repair bill, won't replace wire harness. Disappointed w/ lack of responsibility for poor design.

Lennox products are very efficient. But the costs of product and repairs in my opinion make it a bad value. Have unit that just went out of warranty. Replaced blower 2 years ago. Went out again. Cost to replace was 1700. Dollars. They have one year warranty.. Next unit will be a Carrier.

At the end of June 2022 our (5 year old) heat pump failed due to a faulty coil. Our service vendor ordered a replacement coil which was under warranty on the same day. In mid September, the part still had not been delivered and our A/C was still not working. We live in Florida and it’s not okay to live without A/C. I ended up ordering a new system from York to replace the Lennox unit since there was no indication of when the part would be replaced. I had no recourse and no other possible solution. I took Lennox to small claims court and was unsuccessful in recovering any cost associated with the breach of warranty. I will never buy a house with a Lennox system or purchase a Lennox HVAC system.

We bought a new Lennox furnace in February 2021. It was working until this past Saturday. We called the installers and they came out to look at it & determined it was the gas pressure regulator valve that had gone out. Of course the local Lennox parts warehouse didn't have any in stock and when the part arrived, it was the wrong one! Once the correct part was received, the furnace still wouldn't work so the installers called Lennox and were told to replace the motherboard - which of course Lennox did not stock! Been without heat for close to a week now with no relief in sight - for a Lennox furnace that isn't even two years old yet!.

We spent $20K+ on an Air Conditioner condenser and a IComfort Wi-Fi thermostat from Lennox. Seven years later, both the condenser AND thermostat are dead and inoperable. Lennox has an opt-in requirement or else they deny extended warranty claims from years 6-10 - but fortunately we live in California where shady small print like that is prohibited so they have to cover the condenser part.

My Lennox Air Conditioner coil was found to be leaking August 2022 by a local certified HVAC specialist. My system was in use for one year and likely was installed with a known faulty unit. There is history of Lennox providing faulty coils to their customers. It does not appear they are trying to fix this trend. It is leading to customers having to pay untimely labor and repair costs. Additionally, the amount of Freon lost to countless leaking coils has environmental and safety implications. Hopefully EPA is working to hold them accountable in this area. I have lost confidence in the Lennox company at this time.

If I could give these guys negative stars, it would be infinite. I've never waited on hold so long, so many times, and with NO call-backs when requested for a single issue. The reps (when you actually get ahold of them) are dismissive and unhelpful. I cannot in good conscience continue to be a distributor for their products as a result of the lack of ability to stand behind them. I will go out of my way to sell anything else but a Lennox product from here on out, and if the customer still insists, I'll be directing them elsewhere. I will absolutely NEVER do business with this low-rate, unable, useless, tiresome, worthless, infuriating company ever again.

I have a Lennox air conditioner that is 1 1/2 years old and needs a new evaporator coil. The cost will be $3,100 to replace evaporator coil and add refrigerate. I just discovered Lennox settled a lawsuit due to faulty evaporator coils. Had I know this, I would have bought another brand. I am extremely disappointed that I bought an expensive AC and less than two years later I have to replace the evaporator coil. Lennox told me it was uncommon to have faulty evaporator coil. Is there a way I can get added to the lawsuit?

Updated on 01/24/2026: I bought Lennox elite EL296UH070XV36B-02 furnace on Aug29,2012. In Oct 5,2022 the blower is stop working just one month past the end of warranty. There is no any error code on the control board. I did search through internet and did some test and looks like the motor control module has issues. I take the module to parts and try to test it, but I cannot find any technical documentations show the spec. of the 3 pin connector to motor. So there is no way to confirm this part is really bad or not. In the end I spent $456 bought a new module (It is a non-refundable part). Fortunately my bet is in the right side.

Had a whole house install done a year ago and Saturday evening came home to a 85 degree house. Checked the unit outside and the compressor and lines frozen. Called the install company and they couldn't get out until Monday. Not wanting to wait and knowing my way around A/C systems I removed the panel on the handler to have a look at the coil and discovered the glue that holds the insulation on the top panel had failed and the insulation fell on top of the coil. Naturally it caused the coil (with the insulation on it), lines, and compressor to freeze in a solid block of ice. Used a fan to thaw the ice catching as much of the water as possible, replaced the panel and started it back up and it worked.

I’ve had a Lennox unit for 3 years and each year I’ve had issues that have costed me over 900 dollars to Fix each time!! They are the worst, if you call their customer service you can’t get through. You have to use special thermostats that cost 1300 with installation! It’s a rip off! By far the worst company in my books. Save yourself the trouble! I never write reviews but I must warn people how awful this company and its products are.

In April of 2015, I purchased the Newest and Biggest Air Conditioner/Heat Pump Lennox made for residential housing. Highest efficiency and what I thought was the best quality in the USA. The unit always had to have the drain line cleaned out or it would shut off, and then in June 2020, the Coil went out. Part was under warranty, but I still had to pay for labor and for the cost of freon for this repair.

Purchased an AC unit through Costco in 2014. Two years into ownership we had to change a part in the air handler. On 8/15/22, the coil and compressor blew, and Lennox could not provide the parts even though the unit was still under warranty by 2.5 years. Because of that, I had to replace the unit and I could not afford another Lennox. They refuse to compensate me in any way even though they could not fix the unit because of the availability of the parts.

May 2022 is when we had our Lennox system installed. After two 2-3 Months in, our 4k air handler with 24k med Static (4)ducted unit, cannot cool down our home still. Does not blow enough air and or will slow down itself and not cooling down our 700 sqFt.. downstairs: example 100 temp outside 85-90 inside home, cooling temp set at 62 lowest with fan speed set in high.. SP (supply power) set at 4 max.. Have to Run cool all day to try and cool down. Electric bill has increased 4 times normal amount and system takes 10-12 hours to ramp up. By this time we are shutting it down..

My Lennox Air Handler stopped working on April 2022. The air handler was built on 2016. A normal air handler should work around 15 years, but mine worked 6 years, which is just 1 year after the 5-year warranty. It is pretty clear how terrible the product quality is. Originally, I trust Lennox and thought it should be a small problem and still manageable, but my trust became a nightmare. Finally, I paid thousands to replace a new one after several rounds of repairs.

I will never in my life purchase from this horrific company ever again. I've only had this system for ONE YEAR and it stopped working due to a leak. It cost me $1035 to replace with the coolant that leaked out, labor, and this is with finding a stop for the leak! I didn't even have to get new coils which would have been way worse. This company is deplorable, would not reimburse me for this bogus product due to their negligence. I waited on the phone for ONE HOUR to talk to a "customer service consultant" who was rude and disrespectful and didn't help me at all. I would never use this company again.

My unit is 13 months old. As of March 2022 I have paid $1800 to get cool air in 100 degree temperatures in Texas. Since July 21 our unit was out for 11 long days. Getting replacement parts is almost impossible to get within a reasonable time. Our parts were under warranty but to re-install, it was quite costly. I am a retired 74 year old in a fixed income. I replaced this unit June 2019 thinking I was not going to have any concerns for at least 5 to 10 years. DO NOT BUY LENNOX!

My unit is only 15 months old (moved in April 13,2021) and has been having issues cooling since March 2022. The original Installer (house was a new build house) came and worked on it looking for leaks and couldn’t find any in house so they changed the outside coils in June. That didn’t fix the problem. They came back this week August 1 and said it was the TVX controller, BUT there aren’t ANY in the USA and they have no idea when there will be any for at least 2 months minimum. On top of that, the repair company wants to charge me the labor of $1600 to fix it…if it ever comes in because it took them beyond the warranty date to find problem.

I have had a brand new Lennox air conditioner for 1 year and 2 months before the compressor froze and now has to be replaced. I submitted warranty claim June 2022 and it's now August 2022 with no air conditioning in South Carolina. I would not buy Lennox again. Their product is crap and customer service is condescending and obviously inept. No one should have to wait 3 months for warranty replacement. Not to mention the product lasted 1 year and 3 mos. Not a fan. Complained to BBB and Consumer Affairs and still no help! DON'T BUY LENNOX.

In 2016 we installed a Lennox AC Unit for the upstairs and a Packaged Unit for the downstairs. We have a 10-YR Warranty. We have an annual maintenance contract for the HVAC units. In 2020 the coil for the upstairs unit had to be replaced due to leaks. Total cost to diagnosis, deice and then install new coil was $1,700. Now in 2022, the downstairs Package Unit coil must be replaced. Labor to install, plus other expenses will be $1,800. It’s now been 7 weeks and we are told the coils are backordered with no estimated time for delivery. In the meantime, it’s 80+ degrees downstairs. It’s obvious Lennox never fixed the design / manufacturing flaw with their coils from the 2015 class action lawsuit. What are our options?

Last summer (July 2021) our A/C unit stopped blowing cold air. Upon further inspection it was discovered that the evaporator coil was leaking. Due to Covid affecting supply we were without a/c for about 6 weeks because the parts were on back-order. In South Texas on average the temperatures reach almost 100 degrees or more everyday in the summer, and having three children it was absolutely miserable.
