    HIGH HUMIDITY HIGH EFFICIENCY FURNACE. They know this, yet they do not include a dehumidifier. Caused breathing problems and coughing since unit installed. I had a UV light installed and a separate dehumidifier, 600$ more to spend. Unit was 17,000$. DO BETTER, LENNOX, a lot of bad reviews. CLASS ACTION LAW SUIT for all units replaced to restore your reputation. Lifetime warranty on all parts and units. A dehumidifier with a humidifier attached.

    Ac unit went out after a little over 4 years. The entire unit had metal shavings, Needed a compressor, Needed reversing valve, Condensing coil, and there was Metallic debris throughout outdoor unit. Was still under warranty however, Lennox did not want to give me a new unit. I ended up installing another brand and will not recommend Lennox due to quality of product and warranty or lack there of.

      I bought a new Lennox system in December 2018. I was told it would be more efficient than my old Trane system that was still functioning. Two months later, right in the middle of winter while I'm in the hospital, the unit won't work. It came with a defective part. Finally, after a full day with my condo at 40 F, it was finally working again. Now, six years later, the unit doesn't work again and the technicians are stumped. It is incredibly unreliable and overpriced.

      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.

      I called an AC company to verify the problem and indeed they agreed that it was the blower fan motor. They asked to be paid for four hours of labor at $220.00 per hour or $880.00 to replace the blower fan motor. I said NO because I felt that this was too much for a job that is no more than one hour to replace that motor. I called Lennox and asked them to supply me with the part that was under warranty and they REFUSED to do so. They kept telling me that I have to go through one of their dealers. In other words, they want to force me to go through one of these dealers while they do not cover the labor cost and have no control whatsoever of what these dealers charge, who charge more than brain surgeons at $220.00 an hour. It is insane. I called repeatedly their consumer consultant line but nobody answers that line. I was on hold twice for more than two hours each time. Totally Ridiculous.

      BE WARNED. This company is a sham company because they take your good money and then they have ZERO CUSTOMER SERVICE when you have a problem, and you will have a problem because their equipment breaks down all the time. They sell overpriced equipment while they provide zero customer service and down right lie to consumers. Stay away from Lennox. There are much better AC brands like Trane, Carried, American Standard and so no.

      I have two projects in two different houses right now that I am replacing again ac systems and I have received offers from two local Lennox dealers but I am completely excluding LENNOX at this point due to the discovery of complete lack of consumer service one their part. No more LENNOX for me because in my opinion this is a very bad company that takes the money from uninformed consumers and then turns around and provides ZERO CUSTOMER SERVICE to these consumers. It is rather sad to witness American companies act in this manner and degenerate to the point of non-existent customer service.

      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.

      We felt unheard and unsupported throughout the process, which is the opposite of what you expect when investing in a product that is supposed to be backed by a decade of protection. Clear instructions or even a sense of willingness to help would have gone a long way, but none were provided. This experience has left us questioning the company’s commitment to its customers and the value of its warranty promises. We hope management takes this feedback seriously and improves both their service approach and their clarity regarding warranty coverage.

      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.
