Lennox Reviews

Lennox HVAC units have a long history of premature evaporator coil failures. In a 2015 class action lawsuit, Lennox had to provide compensation to some customers regarding coils. But of course Lennox denied the claims and accusations in the suit, as the corporate attorneys almost always advise companies to do. Did they correct the coils problems after that? I can testify that a Lennox LRP16 unit manufactured in 2023 had coils that failed after only 2 summers. And though the coils are warranted for 5-10 years, customers pay all labor & refrigerant charges for the repair ($2,570 for us). In our case, the coils replacement part was not being manufactured anymore so the entire unit had to be replaced by a LRP15 unit.

Perhaps they know that the design/manufacturing changes needed to fix the coils problem haven’t been made because their HVAC warranty now stipulates that you must use arbitration (an arbitrator of their choice of course) to try resolving issues rather than joining a class action suit. Lennox appears to be playing defense instead of aggressively pursuing the improvement of product quality & reliability. Are they still manufacturing & selling LRP16? Lennox won’t answer that. If so, are they informing customers about the history of premature coil failures on that unit & that the coils replacement part for that unit is no longer being manufactured/available? Yeah right.

If the coils fail on our new LRP15 unit just installed will that part be available? Are the coils on this unit essentially the same as the defective ones used for the LRP16? If different, how so (other than different refrigerant, which btw may help lengthen the life of the coils)? Lennox won’t answer those questions either. Which tells me this: they know the honest answers, if said out loud or put in writing, will further tarnish their poor reputation. For us, it’s likely just a matter of time before I’ll be dealing with another labor & refrigerant bill for replacement coils. Lennox responded on May 28, 2026 by apologizing for my frustration and sent basic warranty information, etc. which emphasizes their favorite part of the warranty… only the parts are covered, not labor or refrigerant.

I appreciate an apology but it is an empty one unless accompanied by a change in behavior or action. Their company values, per their website, include “We are always honest, ethical, and safe.”  I do not think it is ethical to knowingly sell units that clearly have durability flaws in the coils & for which the replacement part is not available. In fact, per the FTC, failing to disclose important information that could affect a consumer's decision falls under the category of deceptive business practices. I believe Lennox should be appropriately investigated for this.

It’s Monday night and since last Thursday, my temperature inside my house has been 85 to 88 degrees. I have a one-year-old and an 83-year-old mother in the house suffering through this. Have contacted Tempo who installed the unit and does our maintenance 4 times so far, to check on the status of the repair and have heard absolutely nothing. People out there, be careful if you are considering Lennox or Tempo in the future. Amen

Everything worked quite well until the late fall of 2025. We had had the system for almost two years. When the temperatures fell into the lower 40’s, the Lennox system quit heating and would just blow cold air. I called Bellows and they sent out a technician. After explaining my problem one of the first things he said was, “Look how you’re dressed.” I was in shorts and a T shirt. This was before he even checked the unit (he later denied saying this upon his third visit). I told him my old thermostat registered at 55 degrees and he told me those old things didn’t work. I told him again, the unit just blew cold air when the temperature got into the lower 40’s. He checked the unit said everything was working correctly and left.

When the temperature again got into the lower 40’s, the unit still did not work. I called again and the same tech came out and said he couldn’t find anything wrong. I suggested maybe I wasn’t using the remote correctly and he agreed and left. I made sure I was using the remote correctly and the unit still did not heat our home and blew cold air. I called a third time and Bellows sent the same tech. By this time something else had gone wrong with the unit and it no longer worked at all. He checked it and did not seem to know how to get into it to look. He beat it up a bit taking a panel off. When he was finished, he blamed the problem on a power surge and said I needed to call their electrician. By this time I was done with Bellows Plumbing.

I called Lennox and an overseas service representative said I need to call Costco and gave me a number. When I called the number another overseas rep told me if I gave her my bank account number, I had won a $300 gift card. So I had been given a scam number. I found the correct number and the Lennox/Costco rep talked in circles and took no interest in the scam number. So, I have a $10,000 Lennox mini split unit in my backyard that I have not bothered to fix as of May 14th, 2026. Why throw good money after bad?
