Lennox Reviews

My AC broke last year. Luckily, my home owner's warranty sent a contractor and installed a brand new air-conditioner unit. They installed the Lennox air-conditioner. This year, the AC broke again. The inspector said that it's the compressor and it was a factory defect. Luckily, it is still under the manufacturer warranty. He said he has to send the picture of the compressor and get a new one from the manufacturer so he can install it. It has been three weeks of over 90 degree, 100% humidity, mid July in Mississippi. I have been following up with the contractor every week. Every time I call them, they say they are waiting for the part to be shipped from the Lennox manufacturer and that they will let me know when the manufacturer ships it.

Model M/N 14PHX-036-230-21. 4 year old house with multiple repairs, some repeat failures like - blower motor 2X with one covered under 2 year warranty, blown start up capacitor 2X, recharge system 2X with a suspected leak in the evaporator - at least $500 - $600 to recharge. Now I need to throw more money to get a leak test and if the evaporator is defective, high labor charges to replace it - another industry scam. Every visit outside the warranty requires a trip fee at $75 - $109 per visit - total maybe 5 visits.

I bought a 14ACXS042 Lennox merit AC and it is not cooling. Technician stated I needed to replace it. Lennox states that it has a 10 year warranty if you register the unit. Registered mine right away when I bought it 5 years ago but I was told that I must have not registered it within the 60 day period because it only showed 5 year warranty. Yet they were not able to tell me when it was registered because according to them the system doesn’t given the date registered. Really convenient for Lennox. I was also told that even if I did have warranty it only covers parts and if it needs replacement they will not do anything about it. I do not recommend Lennox. Save your money and a headache.

Extremely poor “Customer Support” or should I say absolutely NO support at all. Purchased a 12K BTU Mini-split system in 2017. It only worked for 2 ½ years before it failed. According to their warranty policy, I’m forced to call a Lennox “Authorized Dealer” who attempted to fix it while building up a labor cost of $1500 CDN, but the unit was never repaired. The “Main Board” was replaced twice, the compressor was replaced and the indoor control unit was also replaced. Nothing worked.

Horrible experience dealing with Lennox. I have a 6-year-old system installed in our new construction home. I wished now I had the information of the history of coil failure they have had for many years including settling a class action suit on same in 2015. Unconscionable that after all this time this is still an issue with Lennox. They tell me my outside part of unit is covered under the 10 year warranty but attic unit is not? Whole system installed at same time why is one covered and other not? Now they tell me that my unit in attic which has the failing coil unit is listed under another homeowner, what the hell? Never buy any Lennox customer service sucks on hold for hours no resolution. Next step small claims court since they are based in Dallas perhaps that may work??

My new home was installed with a Lennox Air Handler System that is now inoperable due to the evaporator coil going bad. The coil is defective due to the copper parts corroding. This product also has a recall that has existed since they put it on the market. When I contacted customer service, they basically told me to join the class action lawsuit which I attempted. However, that lawsuit (which was settled) does not apply to my specific product. Now I am faced with having to purchase a new system with no help from the manufacturer who intentionally sold and benefited from their cheap products. Consumers need more protection from shark companies like this. I will continue to spread the word that this company is not for consumers in hopes to save the next person from spending a fortune to correct their clear negligence.

Worst company to deal with. They will not stand behind their warranty by any means. They don’t even have parts to fix their units. When asked what they were going to do since they didn’t have the parts to my unit that is still under warranty I was told to buy a new one and that they were by no means going to give me a discount towards one since they can’t stand behind their warranty. While reading online I found that they’ve had a class-action lawsuit against them for knowingly sending out units with subpar parts. STAY FAR AWAY FROM THIS BRAND!

Our $20,000 HVAC unit has required more than a dozen service calls in the first 3 years amounting to almost $2,000 in repairs. Dealing with the corporate office is a nightmare resulting in no resolutions. You will find yourself stuck between the dealer and corporation with neither able to come to a resolution unless you are willing to foot the bill. Would NEVER consider buying a Lennox product again!

I purchased a very expensive HVAC system about 3 1/2 years ago, it was a Lennox product. About 4 weeks ago, the system malfunctioned. I contacted the service dealer who installed the product and had been maintaining it for service. I was told that the coolant leaked out because there was a faulty soldering joint. I contacted Lennox and was connected to someone in customer service who robotically continued to tell me that it wasn't covered under the warranty as it wasn't a part. I attempted to explain numerous times that it was a manufacturing defect in the soldering job. I asked to speak to a manager and was only able to leave a message.

Poor customer service that don’t keep warranty information updated thereby making it impossible to apply for warranty through its dealers even though it’s valid. My system was installed in a brand new house in 2105 but we were the first buyers in 2017. Warranty is effective but Lennox won't proactively fix the warranty end date in their system even though I provided builder paperwork. As a result dealer can’t validate warranty through their system and won’t schedule the repair. Lennox won’t allow me to call on behalf of the dealer. The dealer refuses to make a second call. I am stuck in a Catch 22 and while Lennox says it’s ‘understands’, it won’t allow me to get the under warranty parts unless the dealer calls since customer is not allowed to order the parts! I will not buy a LENNOX product for the ridiculous reasons I got from them … They are dishonest.

My unit is 10 years old as is my house and now evaporator coil leaks. Need to be replaced for the second time. Lennox won't work under warranty - it expired not to say that the new evaporator was only 8 years old - installed under recall in 2014 or late 2013. Original installing dealer do not work with Lennox any more. It will cost me a much and I will not go with Lennox. Wish I know that before I purchased my brand new home from reputable builder with Lennox a/c product. Stay away from Lennox product. Product is bad and practical warranty even worst.

If you buy a Lennox product, don't rely on the warranty or the customer service. 2+ hrs on hold over the phone and all of my emails were completely ignored. I wasn't able to reach anyone for the past 6-7 weeks.

Just over 5 years and my top of the line Lennox icomfort thermostat has died. The 1.5F capacitor inside has leaked all over the electronics inside. This has happened just outside the warranty period. This thermostat was multiple times the price as a google nest or other wifi thermostat, so I would expect it to last a lot longer. I have contacted Lennox and they will not replace it or give me a discount on a new unit. I believe the thermostat was $700, and when I purchased it, I bout a gas furnace, heat pump, and electronic air filter all at the same time. with installation from one of their distributors. For a failure like this it has most likely affected many users, and should be recalled in my opinion. It looks like the capacitor has been leaking for quite a while.

ML195 95% Furnace failed after 8 years and 34 days. Repair was not an option given the amount of deterioration and rust. During the life of this product several parts have failed and were replaced. I contacted Lennox consumer affairs regarding any available warranty and of course none available. In my opinion this unit should not have failed in such a short period of time.

I've been an HVAC technician since 1991. Lennox equipment seems to be constructed ok but good luck to you should you have an issue with residential equipment. I have screen shots that I would be happy to share of being on hold with Lennox support trying to deal with a customer's warranty issues for over 2hrs without getting to even talk to a representative. My customer continues to deal with a gas valve issue on a new furnace in -30 degree celsius weather. Time on hold with tech support on this issue alone is now up to 3.5hrs so far without resolve. We don't get paid to sit on hold - can't spend much more time trying to help this customer and they really shouldn't have to be paying for any of this repair.

I moved into my home in 2013. The home was built in 2004. The original AC unit was with the home when we purchased it, and we didn't need to replace it until 2018. We decided to go with the Lennox unit because we were able to get financing through Costco. We thought we were purchasing a long-lasting unit for our home. The joke was on us.

Sat on hold for Lennox Warranty Department for over an hour & 40 minutes yesterday to try and talk to someone about my 4 year AC unit that blew a hole in my Evaporator Coil. No replacement parts available, no AC for 3 weeks now and nobody answering the phones #LennoxLetMeDown

I bought the top of the range Lennox high efficiency furnace at the recommendation of my furnace company, assuming reliability at the price I paid. Instead I got a lemon. Despite being the most expensive one, the secondary heat exchanger literally burst with corrosion after only 4 yrs. I had it serviced every year. Meant to last 15-20 years. It literally spews out acid and carbon monoxide over the system and onto the floor. They are not accountable for their quality and do not give an explanation. Lennox will never replace the furnace but want the whole thing stripped down, and don’t care about collateral damage. I will not be looking at Lennox again.

REASONS TO NEVER BUY ANYTHING FROM LENNOX OR CRISAFULLI BROTHERS. Below is a four page timeline of warranty issues, cover ups, "training opportunities," communication issues and poor customer service on the part of Lennox and their local sales reps. Based on my experience with them, their lack of follow through, lack of an appropriate response to our situation, their inability to say "We're sorry" or "How we can make this right," I will never buy from either of them again or recommend them. On their website, they "guarantee outstanding customer service," their actual practice of dealing with customers couldn't be farther from the truth.

I had this heat pump and air handler installed on 10/13/21. Previously I had a Trane unit which lasted 18 years with hardly any issues. I decided to give Lennox a try because of the name recognition and good reviews. Wow, I am really disappointed with this unit as it did not work from the day it was installed. After the installer left the air did not stop at our intended target of 77 degrees and it was under 70 degrees when we woke up in the morning. I tried shutting down the unit but it wouldn't turn off. Tried putting on the heat but that didn't work. Another technician came out on Saturday and said the wiring was not installed properly and tried correcting the error. Well, at the end he said it was the board that was damaged and they needed to order the new part. A new unit should not be allowed to come out of production with these type of damages. A new board, REALLY? I should have gone with Trane and regret my decision at this time.

Our $10000 $ Lennox HVAC was installed 07/31/18. The AC failed after 2.5 years of TUCSON summer. The heat - cool pump, meaning the main part failed and BROKE. Before This Unit, I had a unit which worked for 35 years without any maintenance. We are not happy Lennox owners. I want my money back. It worked for two years and now the house got up to 85 degrees during late afternoon heat. called Lennox company for tech specialist -- was told that box coil, cooling pump, have to be replaced (leaking) -- They code me for 1850$ as a labor cost. I am still not done with my monthly payments and the unit broke already and they want 1850$ to repair it.

We purchased our Lennox Mini Splits five years ago. Our city offered a nice rebate program as did the chain warehouse we purchased it from. Win Win, or so we thought! We have four headers for our tri-level home. We were told that the one Lennox heat pump could handle up to four units running at the same time. Do they really? NO. We have found that we can only run two header units at the same time. With four units on, efficiency diminishes to the point of uselessness. However, the worst is this: Lennox makes a very unreliable mini split system. We have now had two repairs within five years.

Bought a new Lennox system from a reputable local company who installed it as well as 3 icomfort thermostats. The app stopped working and would crush upon opening leading to the smart feature being lost. Tried to call lennox which leads to nowhere as you get disconnected after an average of 45 min wait... Avoid this company!!!

Purchased CX-25 / SL280V /CH-35/ C-30 with Filtration System & Air Purifier June 2019 up to now the unit has worked well -- 2 weeks ago temp inside house got up to 76 degrees during late afternoon heat (mid July) -- called my original installer for tech specialist -- was told that box coil may have to be replaced (leaking) -- added 3# of Freon in unit -- cool for about 4 days before temp started climbing again -- got up to 82 degrees inside house -- called different service company --was told coil indeed needed to be replace -- 2 years in service -- Lennox certified retailer called around -- no coils available in Houston & surrounding area.

We purchased a Lennox in 2015 to replace one of our units. Let me say, if you are considering lennox, don't. Repair person has been here 4 times in 1 months. The spider wires keep leaking freon. It works for a week broke another. Lennox customer service is horrible. 2 hour hold, they pass the responsibility. This company only wants your money. Not a satisfied customer. They do not stand behind their products. Once you purchase you are on your own. Buyer beware. There should be a class action suit against them.

Purchased new house with Lennox heat pump: 4 Feb 20. First failure of tev valve: 16 Jun 20-required 3 visits and almost one week of downtime in very hot weather. Tev valve replaced and installed: 25 Jun 20. Estimated actual system operational time: 70 - 90 days. Second failure of tev valve: 10 Jun 21. Valve replacement: 16 Jun 21

We had Lennox HVAC systems installed in late 2015 (downstairs) and 2016 (upstairs). They have both required new coils and yearly Freon. Random issues resulting in no summer AC in our Arkansas home occur several times each season. Both icomfort thermostats have been replaced. Parts, thus far, have been under warranty, though labor and Freon have cost us over $1500 a year. So far this summer, both units have been charged, we’ve had a leak test, a fan motor has gone out, and today the blower motor has gone out. As soon as the warranty ends, we’ll have no choice but to replace. Absolute garbage that cost over $30,000, and thousands each year just to keep it running - which it doesn’t for weeks at a time while we wait for parts. I guess HE means you save on utility bills because it just doesn’t work during the hottest parts of the year.

Had a Lennox furnace for 30 yrs. Good service from it. Air conditioner went bad, replaced it with a Lennox. At same time dealer gave me a discount to replace 30 year old furnace (that was working fine). Furnace being 30 years old I agreed to new one. Have had dealer back every year for three years because coolant keeps leaking. Put dye in line to locate leak. Will be back in three weeks to check for it. Repairman stated might have to replace coil in furnace, at my expense. Started research on Lennox air conditioners and WOW do they have a problem with them. My son built a new home three years ago and has a Trane furnace and AC. NO PROBLEMS WITH THEM. As their ad states something like "Nothing beats a Trane", I should have listened to them. Very upset over my problem with Lennox. Oh, did I mention they used to be made in Columbus Ohio, USA but now made, well you know where!!!

Indoor coil 2 years old of course under warranty, leaking internally. Me as a contractor after opening an account with Lennox, then a lot more time to create a warranty claim#, call after call... However 5 days later no one contacted me back as I was told to wait, meanwhile customer No A/C home. Lennox customer support very, very poorly handling the case, 1 time a lady hang up on me. Immediately I called back (30 min later) other person answers explaining me why lennox can not send you an warranty part for replacement. Still No solution for a replacement, Lennox is pure scam! I called back my customer with no a/c home that we have no solution but to look for other brand Air Conditioning... Don't be a victim. I would NEVER, ever, ever buy a lennox product.

Lennox moderated reviews on their own website. I encourage you to attempt to post a review before even buying a product. They will state any reviews talking about customer service or defective equipment will be removed!! Because of how the Google algorithm works the rating for Lennox provided by google is based on their own moderated reviews and entirely unreliable. I thought I was getting a product rated 4/5 stars only to find out that isn't true.

A/C purchased in 2014, worked great for two years then problems started to pop up on parts and warranty coverage. Parts were covered but not the labor which is ridiculously high. 2016 Blower motor had to be replaced. 2020 Thermostat failed plus the TXV unit (whatever that is) failed. 2021 blower motor failed again on Friday afternoon and parts were not available until Monday afternoon because supply house was closed and repair company does not carry spares. It was a hot weekend. The Tech man stated that the blower motors all fail within 2 - 3 years and are only covered under the original warranty. After that the cost will increase by at least $1,000. Total replacement cost over 7 years for warranty parts was $1,975. No response from Lennox. I will never use another Lennox product or recommend it to anyone else plus will stop using the Installation company that sold the poor quality product to me.

We bought a new build in December 2017 and last summer 2020 our A/C went out! All the Freon leaked out because of a faulty coil. We got that fixed under warranty, however the Freon is not covered which cost over $600! Then comes 2021 A/C goes out again. Needed a new Compressor and Freon because it leaked out and had acid in it! Again Freon not covered $700! Just fixed on Monday and now two days later it stops cooling again! Freon leaked out. Another coil is bad. Tried calling Lennox to get some money back for Freon. Was on hold for over an hour to be told, "We don’t cover Freon as part of our warranty." Well, your faulty products made me have to refill the Freon so it should be a covered part. I’m beyond upset and if I ever buy a new system it will NOT be a Lennox! I promise you that!

Updated on 06/25/2021: Had ac company a second time, it quit twice last night. I have a disabled person at home. Their customer no service if you can get a hold of them. I have never had worse ac in my life. They like to take your money, but do not back up their product. It is all about money.

I recently had issues with my Lennox central A/C unit, it was a simple capacitor that needed to be replaced. I visited my local Lennox authorized dealer for the part and I was told they do not sell to home owners and I needed to call a professional to replace a simple capacitor. I ordered the part online through a second party, but I will never buy a Lennox product nor will I ever recommend a manufacturer that does not sell original parts to customers that own their products!!!

525 sq foot unit. 2 compressors blown in 4.5 yrs, last one on was on fire. Lennox knows the purchaser is a legally disabled stage 4 cancer patient. Lennox refuses to recall product even though they 100% know on every level how dangerous their product is and has countless customers with the same frightening product of theirs. Unit(s) were professionally serviced by the dealer. Lennox claims "we're not under any obligation" and then threatens to block me on social media along with sending their lawyers after bullying a 57 yr old grey haired female caregiver for telling her story. Is this who you want to do business with?

My spouse and I purchased new home construction hoping to avoid costly repairs for at least 10 yrs. I suppose we were naive. Two years after moving in, the A/C stopped cooling on the main level. The repair technician discovered the refrigerant level low and traced the leak to the indoor cools. Although the model unit (ML180UH) is under warranty, labor cost to repair comes at about $1700, which is a little more than the cost of the warranted parts. Quality control appears to be a concept no longer practiced by Lennox, assuming at one time they did.

We purchased a top of the line Lennox HVAC system in Nov. of 2013 for $14,804, believing you have to pay more for reliability. Since then, we've had 12 service calls. The system we replaced had been in service for 26 years (Carrier) and the only reason we replaced it was because it was a bit noisy and didn't have the air purifier & humidifier on it but it never failed. If I'd read reviews first, I would not have bought a Lennox system. Now all I can do is warn others.

Since having my Lennox unit installed, it has been unable to keep up with the heat. I keep the thermostat at 77 as it will reach 84 inside the house. I have had the coil replaced within the first 6 months. I also have it serviced each year. My ac guy said it’s a horrible unit and suggest I give it up and purchase a new one.

My Lennox service man has just informed me that the parts cost to replace my Lennox heat pump fan and circuit board is $1700.00. This is a ridiculously high price which I believe is unfair. I am very disappointed that Lennox would charge such an unfair price for these two items.

I never write reviews! And I rarely read them b/c I always feel they tend to fall into two categories: a reviewer writes an overly positive in exchange for some kickback, or a reviewer writes a spitefully negative one. So which is this one? A therapeutic one ... my last effort in dealing with this problem(s). I bought these units (2) on the recommendation of the installer eight years ago. In the course of the 8 years I have to replace the evaporate on both units, and the fan and motor on one unit. The evaporated issue was part of a class-action lawsuit that I found out about too late, Lennox was not willing to help me out issue ... Bad timing, but no good faith effort on Lennox part. The installer felt bad and only charged me for the parts, so the extra cost me was another $2k.

I purchased what was described a a 'Top-Of The Line" Lennox furnace with variable motor blower and a 4-ton high-efficiency A/C system in April, 2014. January 2021 - had to have a new Motherboard installed into the furnace. Cost me $200 in labor. April 2021 - had to have an entire brand new indoor coil installed on the A/C system - the 7 year-old coil had sprang a freon leak. Cost me $725 in labor. $725+ $200 = $925 in labor to repair a system that is only 7 years old. Do the math. That is $132 per year in maintenance costs for this piece of crap. I have written to their "Consumer Affairs" Department and sent them all of the repair receipts. Not a peep from them. Crickets. Lennox is a cheap brand. Poor engineering. Poor quality control. And NO Customer Service/Feedback from their Corporate H.Q. I highly suggest that you do NOT buy a Lennox product. Go with either a TRANE or a CARRIER, but do NOT go with a Lennox product.

Coil on the outside condenser unit leaked and was useless. One month later, coil on the inside unit leaked. Both problems were attributed to weak brakes which, over time, became weaker until broken. To me, Lennox used to be a no-brainer #1 choice. Not after this. Now we have to spend 5k for a new A/C unit.

If you live in Canada buy CARRIER as they have hundreds of companies that sell their products as well as have available parts. They also stand behind their product. Lennox in the city of Calgary has apparently two companies that have parts in stock. My furnace quit working on a Friday evening and I called a service man who did not have the part but said he could go to the Lennox part store on Sat. Here it is April and the parts store is no longer open on weekends for companies to pick up parts and no emergency phone # available until the next business day.

We purchased a Signature Series Lennox Heating and AC system about 3 years ago and the system is still under the Lennox 5 year warranty. The Lennox website offers a "Complete peace of mind" warranty experience. Recently we had an AC coil failure and we leaned that things like coolant and labor are not covered and we received a bill for $2K for the repair Completely misleading and we have "no peace of mind" with a company that left us this vulnerable...

The previous owners bought a Lennox unit (9LPR14HP30P-2A/1618C01790) is not even 3 years ago, I bought this place November 2019 and this unit tripped my breaker, I was told by a professional Tec (ACE) compressor went but it is under warranty but quoted me $2k. My heat worked so I waited until March of 2020 to have it fixed. Now it is March 2020 and my Tech (I use Watts 863-422-2295 for my other property so kept with them) has replaced part after part and the air condition is still not working as they have now installed 3 compressors (with the suggestion of Lennox Tech support) and something is causing it to blow. They have been on the phone with Lennox Tech Support many times now and we have replaced everything they told them to replace. This unit is a LEMON and needs to be replaced, way too much time and parts have been spent on this unit. For all documentation contact Watts, they will have what you need.

I've had my Lennox for a little over two years. From the start the outside unit had been terribly noisy when running. There are times it gets louder and sounds as if a helicopter is overhead. It is right by my bedroom and I can't sleep with it going. I leave it off and I get really cold because the noise is so loud. I have had the installing company out on several occasions and have had them listen to the noise(I record it). They have installed a new shroud twice (the most recent in December) saying that is what is causing the noise and it still is not fixed.

Had installers come out and check tripping breaker. Found compressor had failed. Quoted $2897.00 just in labor to change part (under warranty). Found A person to change part for $500.00. Lennox will NOT honor the warranty the part and replace it. “The warranty part exchange can ONLY be done by a qualified HVAC technician.” What? How come, I as the legal owner have NO control of the equipment I OWN. What does it matter if I return and exchange the part? What does it matter to Lennox what I actually do with the new part? Surely it’s up to me how I use my warranty part? I understand there will be NO warranty on new part if a “non accredited HVAC tech." does the job.

I have had the Lennox compressor replaced twice and all 3 units have the most horribly loud start up sound. It bangs and rattles terribly for about 20 seconds until it calms down and runs. I have had lived in several house in my lifetime and never have I had an AC compressor make such an awful loud sound when starting up. I have complained to the installation company and was told this is normal but the sales brochure brags at how quiet this unit is. Yes, it's quiet after the nerve rattling start up sound. The start up sound is truly scary and startling. The unit cools nicely.

Our $15,000 Lennox HVAC was installed 07/31/18. The AC failed the following Texas summer. The heater failed 01/09/21 and can't be repaired until after our freezing temperatures and upcoming snow storm. We are not happy Lennox owners.

Purchased a new home in mid 2016 with a Lennox elite air handler. Had to have refrigerant added twice and a leaking/defective coil replaced within the first two years (parts covered, not labor or freon). Now the replacement coil is leaking. Getting rid of the whole system, would never buy a Lennox system ever again. They settled a class action lawsuit for this exact thing in early 2016, doesn't look like they did anything to remedy the issue though.

Specifically, on December 05, 2015, I went to Home Depot to purchase a new Lennox Air Conditions/Heat System, with an SEER of 21. This was essentially the top of the lone model in which I invested approximately $11,000.00 for the purchase and installation of a completely new Lennox system in my house. Included with this investment, was a Lennox “iComfort Wi-Fi Universal 7-day Programmable Modulating/Multistage heat/cool/auto w/ humidity Internet accessible.” Model: 103445-04, Serial Number: WS15J03170. Long story short, the aforementioned Lennox IComfort Thermostat has become inoperable within the past two (2) weeks, thus, I have no heat. This is problematic, as me and my wife are both disabled, and in our sixties.

I have had nothing but trouble with my unit and have gotten no satisfaction from the company. I know of at least 3 class action lawsuits against Lennox for the defective evaporator coil that seems fail in under 5 years. The home I purchased in FL was 4 years old, and when I first had the AC serviced 3 months later (4 years and 3 months old), Freon had to be added (twice now) and both the capacitor and contactor had to be replaced. I reached out to Lennox 3 times before they returned any of my communications... only to tell me it's not their problem and they have no intention of helping me fix it. To replace the unit is going to cost me about $10,000 and to replace the evaporator is $4000. I added my name to the active lawsuit I found online (**) and hoping I can get some resolve.

Buyer beware my new unit keeps breaking down, with no customer services follow up. My unit was broken down for over 2 weeks. I called customer care with no return phone calls or follow ups. My switch went out and my Lennox thermostat.

Had unit serviced twice a year as recommended. Air handler tx valve broke, 1 year after warranty expired. This unit only lasted 6 years (5 yr warranty, due to nontransferable warranty. I bought the house 5 years ago). They advertise 10 year warranty, need to read the small print. My a/c co (who is one of their dealers) says they're junk. Beware, you don't want to be replacing it so quickly. Very expensive.

We bought a Lennox central air conditioner system (model number XC14S036-230A09) in August 2016 from a contractor in Montreal, Quebec. In both June and September 2019 the unit stopped working. According to the contractor, the refrigerant had escaped because there was a leak in the system. He refilled the system with refrigerant and, as it was late in the year, he told us to contact him in April 2020, to do a nitrogen split test on the compressor. This was done and we're told there was a leak in a location that could not be repaired. A new compressor was supplied and fitted under warranty in May, and we were told the unit was working properly.

In 8/2018 I replaced my two 18 yr old 3.5 ton Carrier HVAC units with two new Lennox "Elite" HVAC units in my condo in Florida. Now 2 years later 9/2020 I am having to replace the motors on the fan units. I never had a single issue with my Carrier units in the 18yrs they were in service....not one. Let me emphasize this, BOTH OF MY NEW LENNOX "ELITE" UNITS FAILED AT THE SAME TIME! Two years into service and my new Lennox "Elite" units need to have the fan motors replaced.

I purchased an AC through Costco in 2018. The company that Costco used as provider was Romaniuk Heating & Air Conditioning. The AC unit was the EL 16 XC1, the system only lasted 2 seasons and needed a new coil. I was advised that the Lennox system used ADP for the coil system which failed. I am disappointed with the Lennox brand as they do not appear to use good quality parts. Although the part was under warranty, it cost just under $800.00 for repairs.

Our local Costco store has contracted a local heating/oil company to quote and install these systems. We were building a brand new home and wanted to go with a Lennox system but the company first said they wouldn't be able to give us a quote us and after calling back the receptionist was shocked to hear that so she arranged for the technician to call me back. He asked me a couple questions and then emailed me a quote. It was $13,154.00 plus tax for the equipment and $21,162.00 plus tax for installation. The total price was $39,463 so I am betting Lennox isn't selling very many of their systems here in New Brunswick, Canada. I am not sure why that company bid on that contract because they definitely wouldn't be getting any business on these systems.

Do not buy anything Lennox complete junk and Lennox knows it and they could care less! Class action lawsuit and still several customers are without help! We are complete replacing our unit after replacing one coil last August of course one week past the warranty, cost to replace over 2k and now this August the compressor. Not paying to replace another piece of junk! It’s all junk! Again. DO NOT BUY LENNOX.

Purchased the XP16 through an authorized vendor (Climate Control/Services Experts), and I was desperate to get a decent unit, so I went with it, but it’s been so disappointing. We’ve installed new windows, checked the ductwork, and put on a new roof, and I thought “hey, I’ll notice a difference soon.” Nah. Also, the smart thermostat always goes out, and the unit just doesn’t cool. It’s always borderline hot. It’s sad. My son has a Goodman in his 1200 square foot townhouse, and it puts out—ice cold anytime. I was foolish to think that because it’s a name brand, the Lennox would be great, but what a piece of junk. At least it’s quiet (I guess because it’s not cooling haha).

The A/C units in my (5 year new) home were both manufactured with defective coils. Both units have been problematic and expensive to fix every summer. I registered these units with their warranty program and they are supposed to be covered with a 10 year extended warranty. They now refuse to replace that part even though it is a well known problem that was addressed with a class action lawsuit. In summary, Lennox sold me two new units with defective coils, they refuse to cover them under the warranty, and now I am stuck with the bill. Lennox air conditioners are the worst! Do not buy these units or a home that has this brand of A/C units!

New air conditioning system in our new home has stop working twice this year on 20 months since install in our new house. Having to pay $850. The 1st time and two months later $950. Warranty is useless! Only pays for parts. Parts shouldn't have to be repaired in a new system.

Built new house and put in Lennox HVAC system. Blower went out in 6 months. Furnace would shut down and not work. Replaced sensor? Outside A/C coil leaking. Part replaced under warranty but had to pay labor and freon, $550. Then the condensing fan went out. Part covered under warranty put not labor, $300. Now the A/C outside coil is leaking again and system is out of warranty. Junk plain and simple. Have had other HVAC systems last over 20 years. Lennox can't go 2 years without having issues!

I’ve lived in my home for 5 years and I have a Lennox heat and air unit. Four days before the warranty was set to run out my lines froze up so I called a HVAC company to check it out. They said it was low on Freon. They filled it up and four days later it was froze again. So I called them back out to do a dye test and after finding the leak I called Lennox to see about getting the part replaced under warranty. They said it wasn’t covered due to calling about the leak one week too late Even though I proved with documents that the leak had started while it was still under warranty. Buy from a company that will back their products. This company will not.

We built a custom home 4 years ago and had what we thought was one of the best AC systems installed, which was Lennox. We figured by installing this quality name brand we wouldn't have any problems for at least 10 years or more. Unfortunately, that was not the case. In just the last year, less than 4-years in service, we have had to replace the fan on the compressor and add about 12 lbs of Freon since the system was low and no leak could be detected at the time. A couple of months later our AC stopped cooling again and had to pay another service fee and this time they found the leak in the evaporator coil. The system is still under warranty, but you still have to pay labor and Freon which in this case was over $1,500 in total. I will never recommend a Lennox to anyone I know.

I had a major problem with my Lennox A/C. Problem was caused by missing part! Lennox won't honor their warranty. When you call them I waited for 85 minutes. Part was not placed on unit when produced. The repair charges were for labor. But it was caused by missing part. Since was not replaced Lennox won't pay on an invoice charge they created.

I bought a three systems for my home. My previous system was a 13 Seer Tempstar systems. Prior system no problem. Serviced it myself. It last 15 years. Installed by the home builder. Installed in 1999. My new supposedly high premium Lennox systems were installed by Brett A/C in Naples FL and have been a true nightmare. In the last 18 months, I have replaced 2 coils, 3 evaporator motors and counting. The charges so far have been around $4,000 and also counting just for the labor. There was a class action lawsuit for systems dating back to 2007 thru July 2015, but only paid for first five years despite 10 year parts warranty. I was clearly sold a lemon and was not informed by Lennox or the installer about the problems dating back 7 years before my purchase.

We had our house built from scratch and we moved in November 2015. In my neighborhood most got a Lennox installed. 4 and a half years later 3 of my neighbors' units vapor coils failed and then our compressor went bad on our Lennox 14ACX Air Conditioner. Glad it happen before the warranty of the parts expired which will be this November but nevertheless we had to pay a huge amount of the labor and freon. We had at our last house a 23-year-old Carrier unit in which out of those 23 years we had it for 12 years living in that house. You would think these things would give you many years especially when they are new. We make sure in the future not to ever get this brand.

I replaced a 21 year old Carrier unit when I was having the roof replaced. Thought it was a good time to replace the unit with a more efficient unit as it was getting old. What a mistake. The first issue started in about 2 weeks. The unit was very loud and would shake so bad it would rattle the dishes in out cupboards. It took several service calls before they traced it to a bad fan. Fan was replaced under warranty but only lasted a year before it went bad. Replaced again and lasted 1 week. The insulation inside the unit fell down and blocked the airflow. The next item was the capacitor. Now the coil has a leak and they want $1,200 in labor (only the part is covered under warranty) and refrigerant. Looking to buy a new unit, but is sure won't be a Lennox.

My Lennox system, which is just over a year old, has been a huge disappointment and has been very problematic. My first complaint was with the condenser, (the outside unit). I live in a condo complex and this condenser is the noisiest one in the community. The people at Lennox take no responsibility other than giving you a case number when you call to complain. The local dealer is responsible for all issues. The dealer seemed unable to do much of anything to lessen the noise. If the motor starts up as you walk past it, your heart literally skips a beat from the huge banging sound it makes turning on. Once it is operating, it sounds like a massive food processor. Horribly noisy and very embarrassing to have this thing banging and clanging in my community. I paid for the system and clearly had no recourse.

Had a HVAC system malfunction and called the Lennox company headquarters located in Texas and they sent me to my local Lennox provider. I called my local dealer and I knew before hand what was wrong with my HVAC system and I mentioned it when I called. My local Lennox dealer wanted to send a guy here and they were going to charge $100 and there were many more fees that was adding to be over $300 even with warranty. All I needed was a new circuit board that I found in Amazon for $145. I ended up doing it all myself and saved over $200. To sum it all up, Lennox warranty SUCKS!.

We have had a number of Lennox heating systems and have had very good reliability and operation. As long as you get a qualified company to install properly you would be happy. We have had the higher end products.

My Lennox, variable speed two stage gas furnace, is one year old, 04/04/2019, and I am very satisfied to date. Frankly, no complaints. It came with the iComfort touch screen programmable thermostat which is easy to operate. The furnace satisfies the heating needs of a 2100 sq. ft. home. I would recommend the product.

Replaced my old Lennox HVAC with a newer unit. I must say that I'm impressed with the quality and build of the Lennox units. They look modern and function cleanly. I've seen a dramatic change in my utility bills since replacing my old unit.

We had a Lennox 5 ton Air/Heat unit installed in September of 2017, to replace our 22 year old Carrier unit, and our monthly electric bills have been outrageous ever since, as they are $30 to $40 a month more each month. The company that installed it was very difficult to get back here to check it out, and when they did, they said it was working perfectly. I will not buy Lennox again.

Our ac unit makes a loud banging noise upon shutting down. House does not seem as cool as it should be at 70 degrees. Overall I think Lennox could make a better product, we live in a new construction home and have only been in residence 20 months

Our old heat pump worked fine but the agent that came to our home said that even though the heat pump worked okay there were no more parts being manufactured for it. Also, the freon it used was also being phased out. So, we put out the big bucks and bought a top of the line Lennox. Not only was it super efficient in keeping the temp where I set it but our monthly bill dropped. We were total electric and our bill was $140 a month on a budget.

The ac unit has given no trouble and is now 3 years old. I did have a problem after two years with the installing company as I was forced to have a contract for maintenance as part of the financing. After 2 years they upped the price and lowered what was covered. I contacted Lennox and they were very helpful. Problem solved and the installing company agreed to honor the original contract. I do realize that Lennox has to have someone sell their product. The wall thermostat works very well, easy to use. Cools the house with no problems through our unbearable hot summers and also keeps me warm in our slightly chilly winters. After 3 years the unit still looks very nice, just like it did when it first arrived.

Replaced a13 year old AC Lennox system with new one. Old one kept house cool at 74 degrees versus this new one which feels comfortable at 80 degrees on a 90 degree day. Added a humidifier which was installed for free compared to pricing received from other competitors. Excellent quality and reliability.

They are the best in their field. When it comes to keeping cool. They are the guys to go. Product is installed with care. Maintenance is amazing. Never left hanging. If you need cool air they are the guys to call.

Good systems but not without minor repairs. The systems cools on the hottest days. Scroll compressor is fairly cost effective for use in the rust belt. We are happy that the major components held up well for almost 19 years of use. Heating furnace only minor repairs. This is what we use at least six months out of the year.

I bought my home a few months ago, my heating and cooling system have been in since the home was built in 1995, I have had no problems with it. I did have it serviced when summer hit. I have central heat and air. I love my system.

I bought a top end Lennox system for my house in 2007... Loved that heat pump/gas forced air with air sterilizer... Really hated to sell that house. I had a 90% eff. gas furnace and a 19 heat pump. Best system ever.... Just be careful who you hire to install it. Guarantees are by the installer and not the manufacturer.

I have my 90% Lennox since 2006 and I no problems. It is reliable, no noise, no oils, etc. It as installed Pulte. However my analysis indicated that are equal to SQ D. TRANE, Bryant, etc. Been an Architect I know the difference.

I have had this unit for 4-5 years. I have had no issues with it so far, but then I wouldn't expect to. I do like the feature that reminds me that I need to change the filters and to have a regular service on the thermostat panel. The panel is like a mini computer since it is wi-fi connected. I don't have a problem with it.

I had some heating and cooling issues a little more after a year of purchasing it. The parts were covered but the labor wasn't so I still had to plunk down several hundred dollars to get it fixed. The air conditioning needed a new coil (very expensive) and the heating issue was when a component collects dust, the unit doesn't turn off. The system truly needs maintenance once a year. (I didn't have to do that with my previous unit.)

We've enjoyed the quiet and efficient Lennox system. Be sure you use a company that understands airflow and ducts. Our installing Lennox dealer did all the airflow and load calculations to determine size. Now each room is quiet and comfortable!

My grandfather was an electrical contractor for many years. When I asked him about a recommendation for HVAC equipment, he told me that Lennox is the only company that he has worked with that only allows honest contractors to install and maintain. He was right!

I purchased a new central air system in 2017 - a Lennox system and it has been fantastic. I used to install 5 window AC's each spring to try & cool the house - this worked, but there were hot & cool spots. With the new system - all rooms are consistent and I can get the whole house cooled quickly and efficiently. My house is a ranch and all the equipment was built into my attic. It is a Variable Speed - icomfort Control - 3 Tons - two-stage cooling with a SEER of up to 20.0. The thermostat is a Humidity/Dehumidifiy Touchscreen Control.

Nothing but problems since Purchased in late summer 2016 for $4500 CDN. Never worked properly from day 1. Had to have it serviced shortly after installation and add freon, and then every summer at an expensive cost. Faulty coils causing leaks. Part is under warranty but we had to pay an additional $1300 for installation and freon. Very disappointed in Lennox, they don't stand behind their products. This issue had a class action that settled in early 2016. Last time I will buy the Lennox brand.

Our original heat pump was whining, not heating properly nor cooling so had to replace. Chose a Lennox and very satisfied with the results purchased through Costco, installed by a reputable installer. Also purchased an additional yearly check so this way will have no problem if warranty ever needed, runs very quietly. Our neighbor complained before about the noise and now with the new Lennox, he says he cannot hear it at all nor can we as our bedroom is same side. Very pleased with also looks to be well built with added strength in the framing so nothing gets bent.

I replaced my HVAC system this year. I replaced my Lennox Gas Furnace and Trane Central Air Conditioner unit which were about 20 years old and were trouble free. The new Lennox units are unbelievably quiet and seem to be more energy efficient than my older units.

From the service call of my old unit, to the final installation of my new unit they were so willing to answer every question I had. They made the process look so easy. They dressed nice and we're very professional. They were on time and done early with the installation. Very very professional.

I've been dealing with Service Experts Heating & Air Conditioning for several years now. My Lennox system is very good quality equipment. It's very reliable and very quiet, smooth running. The service maintenance program is good also. I have a schedule appointment for every 4-6 months (May or June). The Lennox Air Conditioning system is a part of my heating system which makes it a great combination. The Lennox outdoor unit and indoor coil has a 10yr parts, 10yr compressor, 1 yr ULPP, and 1yr free maint. Which I purchased a annual maintenance plan that covers the service calls. I had this system since 2016. And it's the best investment I ever made. :)

Our Lennox was new about 5 years ago. Because we live in TX the dealer installs a heavy duty capacitor to help it kick on. Within a year this capacitor had to be replaced. We have the AC and Heating under a contract. In March of this year we did have some freon replaced. Despite the capacitor it has been running great.

Purchased Lennox Air Conditioner, Furnace and Humidifier through Peel Heating and Air Conditioning. The system is very quiet, efficient and cools/heats the house consistently without blasts of heat or cold. Recommend the product.

The durability of my unit has been the best. I have no issues with my heating/cooling system at all. When I needed to install a programmable thermostat the system was very easy to assist me in doing so. I'm comfortable all year long.

I had Lennox install a new air conditioner as the old one was not working. The salesperson was knowledgeable, explained my different options, and why the new models are so much more environmentally sound and energy efficient. I wanted to do further research, and get other cost options. When I did get other bids, no one else explained the technical aspects, and seemed to be talking a lot about environmental energy issues, but without much substance. After about a month, I went with the Lennox. What I was told seemed to be true. My house is evenly cool, and my bill every month is half of what it was the previous summers.

Last year, the HVAC system that came with the purchase of my home, went kaput! After trying to put a band-aid on it each time it broke down, my repairman suggested my Lennox HVAC Gaspack because it's efficient and easy to maintain and will last for at least 10 years and that was good enough for me because I trusted his judgment.

I have had my Lennox AC and heating system for about 30 years and haven’t had a problem at all. I converted from oil heat to natural gas and added a/c at that time when I bought my home in 1991 and have had no problems with my Lennox systems.

My AC blew today and I am having a Lennox unit installed next week. Of course, wouldn’t you know it’s hotter than blazes and humid for the next 5 days. I had a Lennox unit installed two years ago in a previous home. Never had a problem with it so that is why I chose Lennox again. I just wish new units weren’t so expensive. Pamela **

Strong, good quality and workmanship. I expect to have alot of cold summers for many years. It cools the house at an even level-no hot spots. Unit is extremely quiet. I am very happy with this product, it wasn't the cheapest but maintains well.

Upgraded my Lennox when building new home 6 years ago to the highest efficiency unit available at the time. Wanted a unit that could also be connected to solar panels in the future and could handle dual zones, and smart thermostat. The unit has worked extremely well heating and cooling total 3900 sq ft. The original Lennox smart thermostat failed at almost 5 years and was covered under warranty although I paid to upgrade to a newer model with additional features. I’m satisfied with this system and it is extremely quiet both inside and outside components. My electric bill shows this was the right choice.

LENNOX system is quiet highly efficient and gets the heating and cooling job done - the install went as planned in one morning and the system was up and running - the new thermostat provides additional options for setting time of day use and separately fan speed and timing.

Beware of buying a Lennox system. The coils are bad and they had a class action on this issue a few years ago. Unfortunately, the coil issue continues and while Lennox will pay for the part if it is under warranty, they will not pay for the labor or the Freon. Our unit is only three years old and we have to pay $600 for the coil to be replaced and the Freon. I wish I would have researched this company more before I chose their system. I won’t make that mistake again. Buyer beware!!

I purchased a new 98% efficient heating and cooling system. The "A" Coil after 2.5 years had leaked the freon out. My unit froze up with ICE. This was a manufacturing defect with the coil. They had to replace the coil. Since they did not make the same size coil- they had to build a new enclosure for the new coil. Cost to me was $700. I filed a complaint with BBB and Lennox. They had a lawsuit where they settled from 2007-2015. ** I did not quailfy. They are still making defective coils. This could happen again. They have no warranty on their coils for the labor to replace- just the coil. Stay Away, Other manufactures (Amana) offers lifetime warranty.

If I could give zero stars I would. In the last 3 years, we have 3 different Lennox air conditioner units that have broke down on us. We previously lived in Houston and our new build home had 2 units where the evaporator coils went out on both and they were only 3 years old. At the time there was a class action lawsuit against Lennox over the evaporator coils, so we submitted claims to try and get some of our money reimbursed but we have. It seen a dime. Now we live in Missouri in another new build home and our Lennox unit that’s only 2 years old has quit working. This time it’s the fan, compressor, and defrost panel that has broken and needs replaced. Never again will we spend money with Lennox...it’s complete junk. We will go with a brand that actually lasts and has a better warranty.

I purchased 2 Lennox units for my new construction home in 2014. I have had multiple service calls to replace parts since, and coils failed on 2 ton unit recently. Lennox will not warranty even though just past 5 year window and admitted if I signed up within 60 days of purchase, would warranty for 10 years. No support for subpar quality products. I will never purchase lennox products again.

We purchased our home in mid 2014 and have 3 Lennox units. We were told we had a 10 year warranty but not told we had to send in information to secure the warranty beyond 5 years. We have had 2 of the evaporators replaced under warranty and now have a compressor that has gone out. The evaporators had cooper wiring that failed due to corrosive fluid running through it. We are a few months outside the 5 years and the compressor is not under warranty. We have had so many problems with Lennox, we are choosing to replace the outside unit for a more reliable unit. My husband is not well and the last thing we need is the frustration of keeping AC running. I would not recommend anyone purchase Lennox products.

Purchased Drees built home end of 2014 with dual zones. 2017 evaporator coils fail because Lennox doesn't care about anyone other than themselves. Both are replaced at a cost of $1200 so now Tempo Air makes out for replacing the GARBAGE they charged me to install. Now one of the replaced ones has yet again FAILED this week, so out with another $1200 and the winner is TEMPO air. No wonder TEMPO AIR keeps installing their units so they can bank on replacing them all such a SCAM. Shame on both of them.

I purchased my new home in 2014. In 2016 the Lennox evaporator coil required replacing; the cost was covered under warranty. Now 4 years later the (new) evaporator coil requires replacing. Parts are covered under warranty, but it is costing me $1,250 to replace the coil. I understand the initial evaporator coil was faulty, but the new one should last longer than 4 years. I'm disappointed to say the least. My preference was to replace the coil with one from Trane, but the cost would have been over $3,000 which I just can't afford.

I had a Lennox A/C installed two years ago. The unit has already broken! And here I am, spending hundreds of dollars to have a TXV replaced, and god knows if this is going to solve the problem. Compare to my other unit, a Westinghouse/Nordyne. It has been working perfectly for 12 years. No issues. That is quality!

After 14 years I decided to replace my old A/C unit. It was not broken and I never had a problem. I was being cautious since I live in South Florida. I decided to purchase a top of line Lennox. Now the problems begin. One expensive problem after another. Original installer/repair company does not honor the warranty. Over charge for every little thing. New repair company now and yet still one expensive problem after another. Very unhappy with Lennox and would never, ever purchase a Lennox product again. EVER! Email ** and I will tell you more.

Purchased their high end Elite Series XP-20 heat pump. The unit is only used during the winter in Florida, so it's not used very much. Last week the a/c would not come on. I called the installer and was told the Compressor, the heart of the unit, was burnt up and would cost over $2K to repair? The unit was only 4 years old and cost over $10K! The unit it replaced was over 20 yrs old and still functioning. Lennox covered the parts, but would not pay any of the labor costs. So, to get it up and running, it would cost another $2K on top of the $10K already spent.

New Lennar home built 5/2016 in central Florida. Del-Air Heating and Air Conditioning did the AC install. Less than 12 months after closing on our new home, the evaporator coil was bad in the Air Handler model CBX27UH-042-230-6-04. Lennar took care of the first replacement coil because we were inside of our 12 month home warranty (October 2017).

Bought Lennox furnace 12/2013. Two years in it went out. Internal water leak blew out a module. Connections were never caulked/sealed. Technician said since they moved production to Mexico, quality has gone downhill. They regularly forget to seal joints, etc. Repair costs $200. November 2019 furnace went down again. Apparently there is something wrong with the heat exchanger. Took two calls to jerry-rig the furnace to work while waiting for a new heat exchanger. Some insulation baffling had fallen, and they think it may have been sucked into the heat exchanger. Two service calls $300. There is no way a heat exchanger goes out after 5 years unless the quality is crappy. Now they want $900 to $1000 to install the new heat exchanger. I've been arguing with Lennox since December. No way I'm paying more money for an obviously poor quality, sub standard product. Communicating with Lennox is like talking to a brick wall.

My husband and I built a custom home in 2016 in Mississippi. The builder, not us, chose to install 2 Lennox heat pumps- a 3 ton unit to service our downstairs of 2400 sq ft and a 1.5 ton to service the upstairs of 675 sq ft. We rarely use the upstairs and have not experienced any problems with that unit other than it is very loud when it switches off and on. The downstairs unit has had to be recharged with Freon every year. After raising these issues with our builder, he wiped his hands of it and said we had to take it up with Lennox. The coils were replaced in September 2019 under the parts only warranty and we had to pay the $650 labor cost.

I replaced a 20-year old heat pump with a Lennox unit less than 4 years ago. 15 months after installation, it required a new thermostatic expansion valve. Labor alone for this replacement was close to $1500. Lennox refused to reimburse me for any of this cost despite the fact that the unit was a little over a year old. Now, a little over 2 years after replacement of the thermostatic expansion valve, the unit is broken again. This is ridiculous for a 4 year old unit. Oh, and we occupy this home only about 20% of the year. So, the Lennox unit is very lightly used but still cannot hold up.

We have been having two Lennox units since 2017. They have been repaired numerous times already, like 8 or more... last time we had to pay $1,500.00 and now they are both broken again. I called customer service to complain and filed a formal complaint in July 2019. It’s now January 2020, NOBODY has contacted me about the situation. I don’t think it’s normal that two brand new units break continuously and the company does absolutely nothing to fix the problem.... This company is very unprofessional and their products are unreliable. Do not buy anything from them. It might turn out to be a ongoing expense.

Bought new in 2011. Have had the refrigerant leak out for a multitude of reasons in addition to failed coils. I'm on my 3rd coil now and the 3rd one only lasted 2 months! I'm near the end of my warranty period, but at my wits end and getting ready to pull the trigger on a better brand. It's not worth limping this unit any longer at a cost of over $1300 in labor to replace the coil when I now only get a couple of months from the replacement, and have to wait a month for the warranty coil to arrive due to being on backorder. Terrible company, terrible product, terrible quality control. Lesson learned, hope anyone reading these reviews before purchasing their junk learn from our mistakes.

Had Lennox heat pump installed 2/2018 in vacation home. Used about 4 months a year. After about 8 actual months of use the fan motor failed. Yes it was under warranty but cost me $400 in labor. Of course Lennox have me their scripted answer about how they have suppliers to blame but I told them I didn't purchase this product from their suppliers. I purchased it from Lennox. It has their name and reputation attached. Never again. Learned my lesson. They use parts purchased by every company that produced these products so don't spend the money for the Lennox name.

My thermostat panel stated that it was unable to connect with the system and thus the heat got turned off. I contacted their service phone number as stated on the panel. They were ZERO help and stated I had to call the installer. Then why do they have the phone number on the panel if they are not going to provide any assistance? And of course this is at night so the installer is not available and no one will be home during the day for the next 3 days as we have to work.

Leaking coil 3 months post purchase. Likely selling same defective coils they were sued over. Read multiple internet reviews and lawsuit before you purchase any Lennox product. Check which HVAC system your builder is installing. Worse part about Lennox is their customer service; rude and dismissive. Remember - Why would they care; you have already bought their system. People have to put time and effort into reviewing a company; so they must be pretty dissatisfied with a product. Do not ignore the warnings from Lennox customers.

In 2015 we opted to purchase the top of the line Lennox HVAC XC25 premium line model. The dealer however was terrible, sizing the unit incorrectly. Fortunately we discovered it before they actually installed the equipment. When Lennox Industries Corporate got involved as we had to take the dealer to the State HVAC licensing board, where we won!, Yet lost at the same time. Lennox simply lackluster in their help, wanted us to sign a waiver of litigation against the dealer in order to offer any assistance. We did not do it. We kept the system and installed it 2 years later in a second section of our home after buying a complete new system made by Trane from another dealer.

I purchased a Lennox furnace and AC unit for my home in October 2014. During this time and unknown to me, Lennox had a lot of problems with leaking coils and finally had a class action suit brought against them. I ran my AC in 2015 and 2016. Then it was completely out of freon. I had it filled and it ran for 2 more summers, then was completely empty again. The cost of filling and looking for the leak was expensive both times. After reading about all of the complaints and dealing with the incredibly rude Lennox warranty department I have decided to junk this 5 year old AC unit and buy a good product from another company.

Words cannot express the amount of disappointment I've experienced with my Lennox air conditoner. In the span of 5 years, I've had to replace it 2 times. I replaced it in 2015 & 2019. I've spent too much money to have so many issues. The time frame in which the air conditioner has malfunction is unacceptable. When I chose Lennox, I never thought I would have so many complications and experience such lack of customer service. I had so many options when chosing an air conditioner and made the wrong choice. I will never recommend Lennox. I know I would only be setting them up for failure.

Purchased home in 2009, the Lennox was brand new. Started having A/C problems after just less than 5 years. Warranty covered new compressor, we had to pay labor plus new Freon, I discovered then that Lennox had shipped this unit in 2009 with Freon 22 which was being taxed extremely high to cause people to cease using. Had to go back with the same type so the cost for a compressor replacement still under warranty was out the roof. We then had to replace the entire system inside and outside. $7200.+. First summer we have had about six (6) evaporator coil freeze-ups. Now we are getting some cooler weather the problems have shifted from cooling to heating. Outside unit freezing up. Solid block of ice. Service man on the way over Tenth (10) service call in nine months. No company can stay in business manufacturing this type of equipment. Not sure they will be around for five years longer to warranty the unit I have already purchased.

Purchased October 14, 2016. This was the brand Costco sponsors for HVAC. I trust Costco. Within 6 months the coil leaked and needed replacing. The fan motor was defective on the outside unit (XC20-048). Now the air blower is defective (11-15-2019). I spent $9000 on this 4 ton AC and I am so disappointed. I wish I had never bought anything from Lennox. I have over $1200 in repair costs so far. I will never buy Lennox again. Service has been horrible. Parts not in stock and I wait 2-5 days to get parts. I live in Palm Beach County in Florida. Having my home as hot as outside is no fun. I can not recommend the Lennox brand. Even the service technicians say this is more defective than other brands.

I purchased a brand new townhouse from Pulte Homes in December, 2013 at the Crown community in Gaithersburg, MD. That was just over five years ago, and it came with a brand new Lennox heating and cooling system. I was recently notified by my tenant that the A/C unit is no longer working. It turns out that the condensing unit outside was leaking freon. But wait, that's not all. The system has an evaporator coil inside the house that was also leaking freon. Please forgive me if I am not getting the terminology exactly right; I am a consumer and not a service technician. All I know for sure is that that not one, but two pricey Lennox products had failed in just over five years!

This is by far the worst tech support ever. When our techs are in the field needing support, they cannot be on hold for over an hour to get answers. They call the office and give me the information and then I have to sit on hold for another hour. Lennox should hire more people to do the job if they want to keep customers. They are not the only game in town. We will try to steer our customers away from this company simply because of the poor tech support we have experienced every time we call in. As of this writing, I have been on hold for 45 minutes and our service tech was on hold prior to calling me for 1 hour and 10 minutes and gave up.

The fan motors have all gone out and I've had to put substitutes on to replace them because the factory doesn't seem to ever respond or have them in stock. I replaced an air coil last August, under warranty, except for the $500.00 labor. It went out again this year at the end of August. The factory does not respond to requests on their web site or phone calls. DO NOT BUY THIS PRODUCT!

We opted to purchase a Lennox AC from Costco in Redding, CA. Integrity Heating and Air is the only authorized dealer/installer in the area. The air conditioning unit is fine. However, we are still coping with adjustments to the air flow as the service team makes appointments then does not show up or call. Despite multiple requests and civility, this company does not respect appointment commitments. They left the wooden forms for the concrete pad and did not remove them; three of the four legs of the unit only make contact with the pad; air does not blow well into the bedrooms, etc. Lesson learned - like buying automobiles, I've also learned not to underestimate the value (or lack thereof) of the company's service providers.

I had 2 units installed almost 11 years ago. Install was done in November 2008. While the units cost was high they had a good rating. Now I am changing my mind! Not on the unit but on Lennox. The condensing coil was replace 1 year 3 weeks ago. The unit was still under the 10 year warranty by a couple of month. Cost was only labor. The coil started to leak again last week 1 year 3 weeks after it was replaced. I contacted the dealer and he said it should not have done this but I would have to reach out to Consumer Affairs at Lennox.

My Lennox signature series have system has had continual problems. The air conditioning failed and cost me $2,000 to repair it. It is only three years old. Now the heating system is not working poorly. I set the temperature where I want it, say 72 degrees. It heats up the house to 72 degrees. Then it turns on the air conditioner and cools the house down to to say 65 degrees. There is cold air coming out of the vents. Then it heats the house back up to 72 degrees. Then it cools the house off again. This cycle goes on and on. It is wasting energy and money to run this supposedly high efficiency system. I would not buy Lennox products if I was you. I dont recommend them to anyone.

Lennox STILL selling the faulty coils that THEY KNOW fail (see the Lennox Coil lawsuit settled 2015). Please read this lawsuit before you buy any HVAC. I wish I had been informed. Bought 2 units. AC Coil (CH33) leaked after first summer of use. $ 2,600 out of my pocket for labor diagnosing and resolving the leaking coil. Customer Service is non-existent. Any self respecting HVAC company would not sell Lennox. Companies that do sell Lennox do so because they know the coils will fail over and over and, therefore, they make a lot of money from you in service calls (only Lennox Dealers can buy the parts; so you cannot use your reputable, independent HVAC agent who probably would have told you not to buy Lennox in the first place).

I've been installing hvac systems for 24 years. Never in my experience have I seen so many problems with the evaporator coils or thermostats. Failure after failure. Many within a year of the installation. It's hard telling the customer that they have to spend even more money to make the system work that they already spent money on or that they are still trying to pay off. On top of that I have to tell them I'm putting the same faulty part that has failed in the first place. Lennox has made no effort in changing the bi metal coil with a aluminum type. It is damaging to the consumer and the companies that install them. Lennox was so misleading in telling us we were selling a great product. What a piece of junk.

July 2016 I purchased a new home with two new Lennox Elite HVAC units. July 2019, evaporator coil in the upstairs unit fails. $780.00 for labor to replace. September 2019, evaporator coil in the downstairs unit fails. $730.00 for labor to replace. If you have a Lennox unit, get a home warranty with a low deductible. Based on what I've read, the problem continues. If this is happening to you, be sure to file a complaint against Lennox with your local Attorney General's office. Can't hurt to get the paper trail going with local government agencies. Lennox knows exactly what is going on and is not going to voluntarily admit any wrongdoing. The proof is the replacement frequency being supplied in court regarding the units in questions. They can't deny documented failure after failure in 2 or 3 years of service. So be sure to provide documentation to your local Attorney General. It will help lay the groundwork for another class action suit.

This review is specific to product support not the products themselves. To keep it short, I needed to know if I could install a UV purifier above the condenser in the plenum. Lennox told me they would not answer my question and that I should contact my HVAC dealer. I did that and the dealer was only able to obtain a document that did Not directly answer my question. Not a way to get repeat business from me.

Kowalski Htg&Clg was the installer. I would recommend him to anyone. He takes great pride in his work and does not hesitate to answer any question you might have. Even more noteworthy he will make any modification if possible. Top-notch installer and does excellent service!!!

I wish I could give zero stars, Lennox does not deserve even one star! Our builder installed Lennox units in our home, as many new home builders are doing here in Central Florida. Seriously, I think Lennox offered these bunk units at a discount and all the builders and installers are gobbling them up, with the promise of future problems resulting in warranty calls and service calls keeping everyone’s business thriving. We purchased our new home in April 2016, after the class action settlement.

I purchased a new Lennox XP20 heat pump and CBA38MV air handler system in August 2018 and for the first month the whole system was shutting down multiple times a day with an over current compressor error code 433. I would have to reset my breaker 4 times a day. After 6 or 7 techs and 4 weeks of troubleshooting they finally determined the control board on the heat pump was faulty and proceeded to replace it.

We purchased a Lennox system about 3 years ago not knowing that there's a class action suit against them. Our system has a faulty evaporator coil unit that leaks. But it's been a real pain to get Lennox to do the right thing. They've been extremely evasive, irresponsible, and frustrating to deal with. Their product is obviously inferior and unreliable. They cut corners to boost their profit margin by reducing the wall thickness of the copper tubing. And this contributed to the premature failure of the system. As long as I live I would never allow myself and everyone in my family to spend money on Lennox ever again.

I purchased 3 Lennox AC System in 2014! Having my first problem six months later with a bad AC Compressor, followed by 3 variable rate blowers, followed by 2 AC Condensers, followed by 3 AC Evaporator! Today my tech rechecked my units to find out I have 2 more bad evaporators as they are leaking again after they were replaced a year ago! Lennox is terrible so save your money and buy a cheaper unit that will last you double the Lennox without hassles of constantly being without AC in state of Florida!!!

Well folks, by now you realize Lennox has a few issues. The main one being that the evaporator coil is made out of paper mache. I don’t know if I spelled that right. But who thought that wouldn’t make a good coil? We just put one in that the board was DOA out the factory. It’s been kind of a race to the bottom, oh by the way the whole coil problem was caused by the global warming hoax, new enviro-friendly refrigerant has pressure of 400+, compared to 200 in the old. Same coil is supposed to handle twice the pressure? Sure. Kicker is that the switch was totally unnecessary.

I wish I would have read these reviews before we bought in 2010. We opted to replace a 30-year old Sears unit because it slowly leaked freon. Had a reputable local installer replace the furnace and AC units. 2 years later I received a card that evaporator coils had a recall. I called the installer who said I would have to go through Lennox if we had a problem - there was no problem at that time. Not long the unit need to be recharged. It had needed recharging every other year since. I missed the class action suit as I didn't know about it. I am now having my AC refilled as frequently as my 30-year old Sears unit. My daughter's new home came with Lennox equipment as well. Luckily they got theirs replaced under warranty when it started leaking - but neither of us would ever buy one again.

I needed a new central A/C unit for my house. I found a local "Lennox Authorized Dealer" on the Lennox website. The local company came to my house, provided an estimate. After sending the deposit they never returned. It turns out the "Authorized Lennox Dealer" was a scammer who has done this before. Lennox does no background check on their dealers, they just promote them on the Lennox website allowing them to scam customers. Avoid and finds a company that takes responsibility for who they promote and call an authorized dealer.

Long story short. I purchased my LENNAR NEXT GENERATION HOME IN JULY 2016. I have two units units on my home (double trouble). It is now August 2019. Counting the two evaporator coils and the two replacements for each unit so far I on on my 6th coil. They corrode in 12 months' time. What more needs to be proven. Enough is enough. I think we all need to contact a big news outlet and let everyone know about LENNOX INTERNATIONAL AND THEIR PARTNERS who pass this expensive trash onto consumers. The best is all these companies knew this was garbage and when you purchase your home you don't even have a choice.

DON'T BUY LENNOX AC UNIT. IT SUCKS. I have had issues ever since I bought it around 8 years ago from Costco. I bought the warranty that covers labor and parts... But the aggravation isn't worth it. Here I am sitting on my sofa with a glass of wine waiting on the technician to show up again... 5X's in one month. I also have a Goodman AC for 8 years with 0 problems. Buy a GOODMAN!! I hate you Lennox!

I purchased in February of 2012. Immediately called the company over problems with it not working correctly. It’s cost me over $30,000.00 now. I’ve gone without heat at times and as of today (August 7th, 2019) the unit has totally stopped. The thermostat is blacked out- not functional and it’s the 3rd one! I have called the company every year about it not working correctly. Countless Techs have been out here. It’s a shame and VERY INHUMAN!

I purchased a Lennox AC unit in May 2013. System is still under warranty and has experienced both evaporator & condenser coil failures. It is week 2 (Aug 2019) in Florida with heat indexes over 100 and high humidity and still waiting for a replacement part. Labor costs to replace these coils is over $2000. After researching this issue, I have discovered this an ongoing issue and still is occurring in 2019. This issue has not been corrected. Also, I just discovered a 2016 class action lawsuit for units installed from 2007 to 2015. I did not receive notification of this suit but it appears it doesn't really matter since the replacement parts are still the original faulty coils. I wish I had purchased a Trane!

As I was instructed by the rep from my ac company after installation I went and filled out the rebate info on Lennox website and was sent a product registration. Fast forward a few weeks, I called to check status and they said the info was never submitted, and the program was over so there was nothing they could do! I will spread the word to anyone who will listen! And will never buy another Lennox product as long as I live! This company will do anything they can to get out of paying a rebate and it’s not right. I was quoted other systems that had better reviews and I chose this product as the ac company has never directed me wrong and has done their due diligence in trying to rectify this problem! Lennox even tried to pass the buck and say it was the ac company that did not file their stuff as all rebates go through Lennox.

I wanted to give the Lennox Industries Inc. a "0" star review. As of 07/30/2019, my AC unit started blowing warm air AGAIN! I had this AC serviced early this month–07/11/2019 to be exact—and the service technician had used a sealant to plug up as many leaks of Freon as he could. To replenish the Freon had costed $99.00 a pound (I needed 4 pounds), and he warned me that the unit could start leaking again at any time. Well, as of 07/30/2019 (a little over two weeks later) I had to call the service technician once more because the unit was blowing out warm air AGAIN! The compressor this time. The technician all but told me that the unit is on its last leg and may conk out at any time, and when it does, it won’t be fixable with the current COPPER evaporator coil and compressor.

I purchased a Lennox A/C system (Dave Lennox Signature Sys. model# SL18XC1) on 4/22/16. On 11/21/17 the Air Mover Blower failed and was replaced by the installer at no cost. On 7/17/19 the Evaporator Coil failed and it cost me $703.00 in labor to replace it. This is extremely disappointing. Evidently the part's quality is not there for this unit. Our previous experience with two other A/C brands was very different. Disappointed Owner in Corpus Christi, Tx.

Known Evaporator Coil Issue! We bought our Lennox Elite System in 06/2016 and the coil had to be replaced 07/2019! At a cost of $1,155.00 for 2.5 hours of labor!! F.H. Furr (in partnership with Costco) charged us $13,600.00 for the system and to install it. They knew about the Class Action Lawsuit and never said a word. Costco should not even be partnered with Lennox knowing the issues that they are having! Plus Costco has never informed their member of the Class Action Suit!! I'll never buy Lennox again and will tell everyone to do the same!!!

Purchased a new Lennox furnace and heat pump in 2013. In 2014 we had to replace the evaporator coil...$989.00 for labor. Now in July 2019 we need to replace the coil again. Lennox will not assist with labor costs. We have had multiple problems with this product. Losing coolant, replacing parts, etc. My advice is stay away from Lennox. We thought we were buying a quality system that would need little beyond routine maintenance. We were wrong. Lennox products are the equivalent of a Ford product... Fix Or Repair Daily.

Now I read this is a known problem with a class action law suit. Don't buy Lennox. I bought the system from Costco so hopefully someone will help us. The part is covered but the labor is $1000. Again don't buy lennox.

Bought this as top of the line 12 years ago. I have since replaced the compressor 4 times and the last one 3 years ago. I now have a system failure and the technician tells me it the compressor! Big Surprise!!! Since I purchased this I have never had peace of mind. The first few compressors were covered under warranty Not the labor or Freon. I was charged for that. The district Sales Manager for Lennox. (Their employee) told me their units only last 10 years that's why they have a 10 year warranty. I have decided not to spend one more dime on this lemon and today contracted with a competitor to rip that POS out and toss it in the street.

Expensive filters which until recently, I could only buy through a HVAC contractor. Wall unit controller is inaccurate and touch screen feature thinks my finger is somewhere it wasn’t. Overall performance last 11 yrs is average but nothing more. 2800sf home initial HVAC cost $25k installed w/ maint plan (doesn’t include filters).

Research Thomas vs Lennox Industries Inc. Lawsuit before you consider purchasing! Evaporatorcoillawsuit.com. Unfortunately I bought a Lennox AC unit from an affiliate Costco business partner in 2016. I trusted Costco because of their reputation. I spoke to a Costco representative and they actually knew about this lawsuit but continue to allow their affiliate business partner company to sell at their locations!

I closed my home in 2013 here in Atlanta. Now I had issue with evaporated coil. The dealer came fixed but Lennox did not cover the part and I had to pay from pocket for the part expense. I am yet to try for the lawsuit money. But overall very bad experience and we have this all over our community.

I bought their top of the line unit just over 5 years ago, their faulty condensers that they got sued over leaked and cost me $1500 to add refrigerant to repair, probably will leak again, but can't replace it unless they discover the leak....SCAMMED by Lennox. They knowingly sold defective equipment at a VERY expensive price and don't stand behind it at all. HVAC service never mentioned the lawsuit or to expect failures.

I originally purchased a brand new state-of-the-art Lennox AC 4 Ton, ECB40 Series Units, Dave Lennox Signature Collection XP25 System, Dave Lennox Signature Collection CBX32MV Units, on June 14, 2013. In the first year since purchased, I had over 24 logs service calls, which require being home for a minimum of a four hour window if not longer, and almost all of the parts were replaced if not multiple times. It got to the point where I brought in legal counsel, and was able to have the national Lennox account manager from Texas, Tim **, and the local Lennox Representative, Robert **, meet with Jimmy, the service tech from Rinaldi’s Air Conditioning (company who did the install and myriad of service calls) with me and my legal counsel at my house on July 25, 2014.

Evaporator Coil Failure in a 50 unit Town Home Community. The Evaporator Coils in our 50 units are failing on a regular basis; some have failed twice and they are approx 5 years old. Mine will be 4 years old and I have to replace it. The installing company is almost camped out in our Community replacing these bad coils. From what I read there was a Class Action Lawsuit for this very problem with Lennox and they settled. Bad deal for those of us that have Lennox.

Just the facts: Purchased a Lenox AC System in April 2016 for $6995.00. This month, June 2019, 38 months after install, system stops cooling. Local repairman came out and added Freon, which was a warning sign of another larger issue. 48 hours later the system stopped cooling again. After two additional service calls they opened the air handler and the evaporator coils were heavily oxidized/corroded. Due to this it was leaking Freon from those coils.

We bought a new Lennox a/c and furnace in August 2016. The system worked very well for two-plus years. In May 2019 the a/c stopped cooling. After two service calls the problem was found to be refrigerant leaking due to a faulty evaporator coil. Never expected such a major product problem in less than three years on a brand new system. We have been told the warranty will cover the replacement part (coil), but NOT the labor or supplies (refrigerant) to get the system back up and running right. The Lennox rep at the Customer Care call center confirmed Lennox will not cover labor or supplies. Cost to us will be about $1000. I also learned about the prior coil lawsuit and settlement involving Lennox.

Purchased a Lennox 14 HPX heat pump 5 years ago and it never worked properly and every accredited repairman that came took money and left without repairing it. Now I have a person that could fix it but I need parts and Lennox will not sell any parts without going through one of their incompetent repairman. Buying a Lennox is the worst decision I ever made.

I purchased this iComfort thermostat with Lennox signature series HVAC from a main dealer in Nashville 4 years ago. The thermostat is very complicated to program. Every time the power goes off, I have manually enter wifi password and reconnect it to wifi. After getting tired of doing this for so many times, I called the dealer and they charged me $99 as visit fee. I was told that it is problem with this kind of thermostat that Lennox unable to do anything for it.

If you’re looking at installing a Lennox unit in your home, I would advise you to run away. There are far better alternatives (Trane, Carrier, etc) with companies that stand behind their products. A quick Google search will reveal a great number of people who have been “privileged” enough to experience the very short lifetime of a Lennox product. In fact, some people have replaced the evaporator coil two, three, four times, in only a 5 year period. Some people are “lucky” enough to get just 5 years out of their evaporator coil. Unfortunately, these people are out of luck as some coils seem to hobble to barely achieve a 5 year lifespan (which is less than half the life expectancy of other units in the industry). I am certain that the coils did not magically degrade to this condition over the last couple of months in which the unit was out of warranty.

My two year old Lennox central A/C system suffered an EVAPORATOR COIL failure. NO air conditioning and the heat is coming! While the part is covered under warranty, THE LABOR is NOT. The labor estimate is $1500. I have been waiting OVER 1 month for my dealer, WK Mechanical, to receive the part from Lennox. The dealer says they DO NOT have an estimate from Lennox for when the part will be received. Then the dealer has to schedule the installation. There is no end in sight. FYI: there was a class-action lawsuit filed against, and settled by, Lennox about failing EVAPORATOR COILS. Maybe it is time for another class-action lawsuit since Lennox learned nothing from the first one!

My home was 2 years old on 4/19. Prior to reaching the standard 2 year warranty on the AC unit, I made sure it was checked for a leaking coil as a large portion of our 500 home community has had their coil fail, usually 2 weeks after warranty expires. The part is covered by Lennox but the labor is not and has cost people anywhere from $600-$1500 in repairs. It has happened so much that people have found a cheaper labor cost which is why the $600 is even on this review.

My mom has had central a/c and heat pumps for many years and she just purchased a new one through a local Lennox dealer 16 months ago and she's had nothing but problems with it. First the installer did not set it up properly, the exhaust tube for the furnace was facing the sensor on the outside of the house and it was starting up the furnace all the time. The heat pump is suppose to working up till 40 degress outside and then the furnace kicks in afterwards, this was not so for her unit, the furnace was working all the time. For the first years of owning this unit her electrical bills doubled, so we requested a Lennox dealer to come to the house and inspect what's going on, they found many problems.

I wish I had read these posts BEFORE purchasing my a/c unit. Purchased Feb 14, 2019. A/C not cooling. Called contractor to check. Coil needed replacing. I'm so worried about this unit. Lennox may have been a bad choice.

I bought a house from Lennar homes last year 2018. Now it's been only 1 year 2 months and my AC is broken. I called the builder and company which installed it. Both of them said they can't help me as it 2 months from warranty. Though the Lennox pays for the part to detect the leak, fix it and to fill the freons the installation company gave me a quote of more than $1000 which is not fair being a customer and it's not my mistake. I would give a negative review for this companies who build such a crap and who is buying and installing it.

Only had unit 5 years and was told today my evaporated coil need replacing costing $2300 + tax. And was told we have to pay even though this Lennox fault. Unexpected cost. Never thought this would happen to brand new home and unit.

We purchased our Lennox package heat pump unit in Oct. 2017. In Dec., the compressor blew up bad enough that they replaced the entire unit under warranty. Now, May 2019, a valve has failed and it's going to cost me $1500 for labor and refrigerant which is not covered. The unit looks well made, but it runs loud and I'm not at all happy about the quality and reliability.

I purchased a Lennox heat pump system in late 2017. The AC quit working a few weeks ago and the second technician who came out said the evaporator coil needed replaced. I had to add 10 pounds of freon for almost $400 and the company wants over $800 in labor to replace it. The evaporator coil is under warranty, but not the labor. I started researching and discovered a class action lawsuit against Lennox for defective evaporator coils on systems sold between 2007 to 2015. Well, it appears this company still has not fixed this issue and is knowingly selling defective equipment. And the companies pushing these systems for sale are probably aware of this.

I have five HVAC systems between my home and business. Three of them are Lennox systems. The two Lennox systems I have at home were installed in 2014 and 2016. These two systems had evaporator coil leaks detected and repaired in April 2019 at a cost of $2000 for labor. Both evaporator coils were under the Lennox parts warranty but the labor warranty had expired after one year. The 2014 coil was included in a class action law suit which required Lennox to cover some of the labor costs. The 2016 coil was not included in the law suit but had the same problem as those coils included in the law suit.

Bought a top of the line HVAC unit in 2017 and have had nothing but problems since installed. I dealt with A1 United (installer). They have been out 8 times in a year and a half. But when I finally said I think I have lemon units they said, "No. Doesn't qualify. Can't help you." Still paying on this unit. Will never buy Lennox again. Junk!!!!!

My unit in seven yrs has needed a new pump, three evaporator coils and now a new compressor. Spent a lot of money on this TOP OF THE LINE unit which does not seem to produce cleaner air and breaks at least yearly. I would never buy LENNOX again. They have done nothing to help us.

Updated on 09/16/2019: We purchased a Lennox because of their strong name and reputation in the industry. I have no idea what happened to that company, but the AC unit I was sold sucks. Within the first 2 years, we were having to shut it down continuously because the outside was icing over. Then the coil goes in April-June. It was under warranty but the labor was not. Now it is September and the thing is freezing up on us again. These units are JUNK. Find another company or enjoy nothing but headaches for the time you own this thing.

Needing to stay cool in the brutal Houston heat, I Spent $7000 less than 2 yrs ago to buy a whole new Lennox system after the original Lennox of 8 years went out. This time the compressor is gone in this one! I won’t have to buy the parts because it’s only been almost 2 years but the labor costs just as much. What a rip off. You’d think after just paying 7k you wouldn’t have any problems with the unit for many years to come. Also when we bought the home new with a Lennox air conditioner we were never told by the builder to register online for the extended warranty. It would have been nice to know that was an option seeing that the first unit went out after just 7 years! This will be my last Lennox. Spending more doesn’t always mean getting more I learned.

I bought 2 high end Lennox Elite units. The coils went out in one unit after four years. They covered the part, but I paid $1,100 in labor. But what I found out next was shocking. This equipment qualifies for a 10 year extended warranty which I thought I had. But Lennox says I don’t because I didn’t register online within 60 days of purchase. Who knew? They tell you this when it’s too late. I’ll never buy Lennox again.

Installed two new units in 2014. 2018- Replaced evaporator coil and blower fan. 2019- Replaced evaporator coil in the 2nd unit. Total cost with warranty - $2,200. This will be my last Lennox unit ever.

In 2016 installed Lennox heat pump. Information was that unit in made in USA. Come to find out it is not totally a US made product. After reading several reviews it seems that the motors and condenser coils have problems. You would think that Lennox would fix the problems once and for all. From what I have read it has not. Part covered under warranty bur labor is not. Told by company that installed my unit that it is because of surges that the unit is taking. I now have to have a surge protector installed to keep this from happening again even though I have a whole house surge protector installed by FPL. I had a Carrier unit for 16 years and did not have this type of problem.

In 2015 we had our heater and air conditioner replaced with a Lennox units. In the first year we did not have an issue. However, from that point on we have been having problems. But first let me tell you about the installer who has been remarkable and has had our back. Now to the issues. First it was the sensors giving us error codes. The installer came out a couple times and cleaned and replaced the sensors and the errors went away for a while. The error codes kept coming up and after a while the system locked up.

I purchased a Heat Pump & Air Handler from Lennox (CBX32MV and XP 15) in 2007. Problems began immediately after installation and never stopped. Things that went wrong? Ambient temperature sensor (twice), condenser pump motor, dual capacitor, defrost board, “stuck” reversing valve, bad circuit board in heat pump, sequencer, bad contactor, and more adjustment issues. Many of these incidents meant lost work time in order to meet repairmen, and massive electric bills when heat pump was not functioning and system was in “emergency heat” mode.

I purchased two Lennox signature HVAC 5.5 years ago. In this timeframe I have had to replace 2 coils under the Thomas vs. Lennox lawsuit. Thankfully, I filed as a consumer. Their crap warranty covered replacing coils albeit $1500 in labor came from me. Of late, living in S. Florida heat is hardly used. When I turned on heat on one unit it didn’t work. Another piece of crap. It cost me $900 to replace the hardly used heating element. No Warranty! Do not purchase a Lennox product unless you like paying for repairs on a 5 1/2 year old units. Lennox sucks.

Please never buy this air. It cost me a lot of money and Costco advertise them, that is how I ended/up buying this junk.

Lennox AC coils failed for second time. Replaced original coils at 16 months from new install and again 14 months later. Unacceptable! Replacement coils have the same on going issue. Class Action lawsuit did not apply to me as we were beyond the date range despite the replacement coils still are a failure. Lennox remains only AC company who continue to use the failing coils.

I have a 4 year old Lennox Elite Oil Furnace that is junk. It was poorly installed (fuel oil running out onto the floor from the outside filter forming a large pool on the floor 2 days after installation) and has repeatedly leaked fuel oil inside the furnace. Fuel oil drips from under the assembly. I have had the authorized dealer/service firm (McKean in Washington, Pa) in here multiple time to fix it, and it just continues to leak. In November of 2016, I spent a 3 week period largely without heat. I gave up every vacation day, personal day and sick day for that entire year to be off work so McKean could come in here nearly every day.

Bought a Lennox furnace & A/C unit in August of 2015 only to have the furnace stop working three times to date. Each time there was an issue with the flame sensor. Last time it stopped working was two days ago in 17 degree weather. I called the firm who sold us this product only to be berated for not spending $90 twice a year for maintenance. Apparently it's our fault for not using their service for maintenance. We have changed the filter constantly, cleaned the flame sensor once and replaced the sensor twice thereafter. I have a friend who bought a Lennox who had the same issue. DO NOT BUY A LENNOX!!! It will only be at your great expense. I am now in the process of looking to replace what was a very expensive, now worthless furnace.

Purchased this unit (most expensive high efficiency they sell) January 2015. Within a month we began getting error code 292 about every 6-8 weeks. This error is presumably reports failed blower motor, but, the blower motor is actually OK, so it is a design glitch of some sort. This error turns off the system requiring a power off and on to reset it. This has now gone on for the last 3.5 years, and the dealer has replaced the motor, several different sensors and probes, and a logic board. None of this has fixed the problem. I finally went to Lennox customer service. They wrote me and asked for all the records for verification, I sent these. However, they then passed it to their local technical rep. He emailed me once with a phone number, but when you call that number you get an "out of service" message. He also has not responded to three subsequent emails.

I bought 4 ton. A/C Lennox through Costco for $4480, 4 years later the blower motor broke. The part is within the warranty. My installer cannot get a replacement because only Lennox dealer has a monopoly and charges an arm and a leg to replace the piece. A friend of mine installed a 4 ton. RHEEM with an A/C repairman for less than $2000. Check with your A/C repairman if you can get parts for your A/C brand that you plan to install.

I brought my furnace 12/12/14 and have had the repairman out here several times. The furnace turns on but the burners don't ignite. It's either sensors not working or so something clogged. I replace my filter every two months so I try to do whatever I can to keep it working but when you buy a lemon there's nothing you can do.

SLP98 furnace and XC17 Air with S30 iComfort - Installed both equipment in 2011. Upgraded iComfort last year. Never ever had any issue. Extreme winter like -35C and hot summer like +35c. Both equipment works smoothly (heating and cooling) 5000sft house.

We moved into a brand new townhouse less than two years ago. It's now had to have the evaporator coil replaced and the condenser coil is bad. Lennox used to have a good reputation. Don't buy Lennox. Worst system ever.

We built a new home in 2016 and purchased our HVAC Air Handler heat pump and AC through Lennox. First year we had 4 parts replaced. - All labor and parts paid. Now we are into our second year and our coil is leaking and exchange valve as well. Parts covered under warranty but the labor into the thousands of dollars. Our installer no longer sells Lennox due to all the problems with the product. Beware... Do not buy from this company. Now two years into a new home build we are looking at replacing our entire first floor units. And we expect the second floor units will not be far behind.

My 8 year old blower motor went out Sunday Nov 18th. The entire system was sized by my installer and approved by St. Louis County Public works based on heat gain cals. We ordered it Monday 10 am 11-19 and finally got it today 11/26 at 11 am. It was made by Emerson Electric in Mexico. Proprietary by Lennox allows them no only not stock it any "parts plus " service centers because it took 5 UPS shipping days to arrive. Now the good part- a 1 hp 2 speed motor that would normally cost $150-250 was $800 excluding labor to install. If anyone tries to sell you a Lennox... RUN!! BTW 2 calls to Leslie ** at their home office went unanswered during us having 4 days of sub freezing weather. As a matter of fact he blocked my cell # per AT&T after the 2nd message. Messages I left him to call me to help locate a motor quickly.

We have a 10 year old Lennox Furnace which has been very reliable. It is well maintained with annual maintenance plan paid to Direct Energy who installed the furnace in August 2008. Recently we had two rare power outages. In Both cases the furnace did not restart automatically when power was restore. The last power failure resulted while we were away for 3 Days. When we arrived home the temp in the house was 11c. Similar thing happened about a year or two ago. We got it working again by turning the power breaker off, and back on, and the furnace restarted, but this does not seem right.

We purchased a Lennox HVAC system after doing lots of research in 2014. We thought we were being smart by purchasing a high end HVAC unit from Lennox. Since then, we have had a leak in the coil which required replacement and now have a carbon monoxide leak in the heat exchanger, which needs to be replaced. Same story as the other reviewers below. Parts covered by warranty but expensive labor costs which were not covered. We will not purchase a Lennox ever again.
