Lennox Reviews

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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