Lennox Reviews

Lennox systems offers an $1800 rebate on qualifying system which includes heat pump, air handler, and thermostat. The system was installed by their distributor who said my system was eligible for the $1800 rebate. The rebate is a lie and they are dishonest. I am very sorry that I had a Lennox system installed. The company lies.

Very upset. My Lennox a/c and heating unit is one year past warranty and the thermostat went bad. To replace it will cost $100 service fee + $840 + tax thermostat. Almost $1000 for a thermostat??? You can’t use generic thermostats or you lose the efficiency of the system. You must buy a Lennox thermostat. I wish I would have understood all of this prior to going with Lennox. Never again will I make that mistake. I encourage all others to do the same.

I give them a 5 for how well the HVAC operates. My home is very comfortable. I give them 1 star for communication. I have sent the company 2 different emails at 2 different email addresses. No reply from either one. Very poor customer service. They put everything back on the installer. They expect them to handle everything. With their recent agreement with Samsung you would expect more. I can tell you now my next system will not be a Lennox. I will go back to Rheem.

Just had a service person come out to my house for a heater not working, for 10 years the system was flawless, now they are telling me my motherboard has went out and my blower motor may be bad as well. Neither one of these products are due to maintenance and I am really disappointed with the product. I wish I would have known all the problems before installing this product. We had to go through the Hero program as we could not afford this any other way. Now we are going to have a big bill. Not happy

It has been an extremely frustrating experience dealing with the rebate process for my new Lennox system. We had a Lennox air conditioner and furnace installed on June 26, 2025, and I immediately applied for the $250 rebate. However, as of today, I still have not received it. The only point of contact for rebates is the Promotions Consumer Team. When I emailed them, I was told that the rebate MasterCard had been sent in November 2025 — which we never received. They promised to resend it, but it still never arrived. Further emails went unanswered.

Our Lennox Merit series ML14XP1 heat pump unit has been a total disaster. In the 5 years we have owned the unit, we have had to have 3 major repairs to the outside evaporator coil assembly, each time causing the gas to completely escape. The first time, the manifold was incorrectly brazed during manufacture, which the service technician re-brazed. The second and third time it was the copper tubing leaking (proved under a pressure test). This nonsense is unbelievable. The service technician told me the only recourse is to buy another complete heat pump assembly, which will also require a new air handler. This is a warning, based on my experience, DO NOT BUY A LENNOX MERIT SERIES heat pump!

The air handler or some other parts have a serious problem. I would like to inform potential buyers to not purchase one. 2 years in a row when going from using heat to using cool a disgusting smell develops called dirty sock syndrome. At less than a year old. Cost of unit $6000. 6 techs could not find the problem. I gave up and called another company from the ones who sold and installed it. They installed a wave R for $900 and the smell was gone. That was last year. This year it happened again after using the heat.

We bought a Lennox Elite heat pump 2 years ago because our old heater kept freezing up in cold weather. We bought our Lennox through Royal Air in Chico, California. I'm very disappointed in the performance of this unit. When the temperature goes below 40°, the heat pump blows cold air for 20 to 30 minutes before the warm air begins. During that 30 minutes of cold air, it brings down the temperature in our house at least 5°. So now when it gets cold outside, it's like having the air conditioner on. We've had Royal Air technicians come out on several occasions and they tell me that heat pumps take 20 to 30 minutes to blow warm air and that's just the way it is. They tell me they get a lot of customer complaints about it. So am I supposed to just live with this? The air conditioner works great, but the heater is very disappointing.

As a reminder to anyone buying a new home be sure to register your air handler, condenser, heat pump, etc., separately. Don't just register one piece of equipment. You must register each and every piece. If you do not register within 60 days, you will have no 3-year labor and 7-year parts warranty. I would bet that 95% of people do not know this fact and new home builders and/or installers might not tell you. Who likes warranty work? If you were told, consider yourself lucky. This is just my opinion. Do your own research! One last point, Lennox Consumer Affairs said this to me via email, "Unfortunately, we cannot control what information the builder or the installing contractor provides consumers." Wow...that is so wrong.

I'm a heating contractor. A client has a Lennox air handler. 5 years ago I installed a new boiler to feed the air handler. This winter the blower motor on the Lennox stopped working. I spent 2.5 hours on hold with lennox for tech assistance. It was confirmed that I needed a new control board. Any other part for a heating system I can find a local supply house. Called a dozen places to no avail. Called lennox again and was told I could only get the part through them but they wouldn't sell me the part because I don't have an EPA number. Was able to order the part off of Amazon.
