Lennox Reviews

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

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.

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.

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

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.

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.

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.

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 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 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 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 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!

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.

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!

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.

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. :)

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.

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.

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.

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.

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 **

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.

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.
