Lennox is one of the most unresponsive companies I’ve ever dealt with. I used their online “contact us” form twice in April 2026 asking basic questions about their HVAC packaged units. I also tried repeatedly by phone to get to the “right” person for answers. Finally spoke with a very polite rep but she couldn’t/wouldn’t answer my main questions. In May 2026, after completing a review of our new Lennox LRP15 HVAC (per their solicitation) I finally got a response. See later in this review. 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. UPDATE October 5, 2026: The evaporator coils on our new unit lasted 5 months & now, predictably, need replacing. And the part is not available!

We're trying to get a a 3-year-old system repaired. We cannot get parts. It wasn't covered under warranty because we bought the house with a brand-new system in it that was only a few months old. Unfortunately, Lennox doesn't have any kind of transferable warranty, so we're stuck paying thousands of dollars to get the unit fixed. The technicians are having trouble getting the parts. It's no fun having no heat in Arizona for a month in the summer.

My Lennox EL195 furnace, serviced every year by the pros who installed it, now requires replacement after only 13 years. The secondary heat exchanger and combustion air blower both are corroded and leak. My last Lennox lasted 27 years. This one is an expensive piece of crap. Never a Lennox again.

Lennox has gone back on their word, and now they are refusing to honor their warranty on a registered brand new AC system the came with a Lennar home. Lennox has managed to defraud an 80+ women who is wheelchair bound, doesn't have use of a leg and arm, who's had multiple strokes. Her AC has been broken for 3 months. Avoid buying ANY home with a Lennox AC system. There is also a class action because Lennox know the AC system was defective from day one. @Lennar #Lennar @lennoxair @carrier #Carrier @trane #Trane #airconditioner #HVAC #AirConditioning #Cooling #HVACRepair #HVACService #HVACTech #HVACTechnician #ScamAlert #BuyerBeware #ConsumerProtection #FraudAlert #CompanyScam #BadBusiness #ConsumerRights #KnowYourRights #HVACScam #ACScam 25m

No help from customer service whatsoever with the comfort app.. I will never buy a lennox product again.

They are a COMPLETE FRAUD. They DON'T honor warranties on their AC systems. They also have defective evaporator coils and compressors. They've known about these issues for a decade. Don't buy a new home with defective AC systems, you'll pay for it later like we did. Other people are reporting the exact same issue. Been fighting customer support for more than 3 months.

We bought a Lennex air unit about 5 yrs ago and have had nothing but trouble for past 3 summers. We should not be having issues this early after a purchase for what says is a top tier unit. Once again it seems to quit working during our hottest months. Please explain that?.. we are on limited income and cannot afford to keep fixing every summer because it quits. I do not recommend this unit to anyone and do your research before purchasing. Save yourself time and money. They are not worth what they cost.

Entire blower motor failed 5 years and 3 months after warranty. Huge expense to replace and since I wasn't the original owner there is no extended warranty. 3 months after the 5 year warranty???? Seems a little bit like crap.
