Original review: May 20, 2023

Unfortunately, I can not say anything good about the Lennox Heat Pump and Lennox Air Handler, purchased through Costco in 2016. The first system failed after 1 year, the second one "upgraded system failed after 41/2 years. Important internal part-reversing valve-developed a leak, which drained the refrigerant. Our Heat Pump became totaly useless.

Contacted Costco/Lennox got absolutely nowhere with them, to find out who would pay for the repair. Lennox has a 10 year warranty on parts, but to replace the reversing valve would cost around $1,500 in labor. We paid originally $6000.00 and now, still in the warranty period we're stuck with additional, huge expense. So, my advice, stay away from the "Lennox" brand. The reversing valve failure points to a poor assembly, soldering job of the valve tubes and obviously poor quality control. Yet, Lennox/Costco would do absolutely nothing to compensate us for this costly repair still half way in to the Heat Pump's warranty. No preventive maintenance would have prevented this poor quality failure!

We replaced our old Coleman heat pump with this absolute junk from Lennox in 2018. Our Coleman was trouble free for 18 years! The Lennox, at two weeks in, we had every tech from the installer at our place, plus a special visit from some Lennox person himself. Since then, we've had to have it worked on pretty much at every change of season as it does like today - 80 degrees out, it has failed to cool at all. Not like it is an extreme, but to Lennox, if it isn't 50 degrees out, do not expect cooling or heating. I could do better with a block of ice and a fan. It has gotten ludicrous, the number of times the installers have come out. They don't even charge us half the time, they are so embarrassed about all the issues we've had.

After only five years of use, I'm calling Monday to get bids to replace with any other brand, even though we spent a substantial amount of money on this junk, but I'd rather kick it to the curb (or more to my liking, over a cliff in flames) than have to endure the problems any longer. DO NOT BUY LENNOX EVER unless you have some strange crush on your local tech and hope to see him/her every couple of months.

    I'll keep it short, crappy product died in 2 (yes TWO) years lol. Lennox replaced all the crappy parts cause warranty, but I am on the hook for the thousands in labor. Lennox said sorry, not sorry, have fun! All I wanted was something small like a jelly of the month subscription

    We bought a new construction house in 2020. We were given a Lennox HVAC, which started off great, really silent and run great. It is just 2023 and it makes so much noise + the temperature I set doesn’t drop but increases. It is on 24/7 but does not cool. Living in California, I am trying to figure out and call as I assume it should be under warranty, but customer service is really bad, no help everyone is expecting to pay for labor cost. Basically spending $$$$ and this is the result in 2 years, as the company claims that they run great for 10-20 years. I am so disappointed, will never shop this brand ever again.

    Well, looks like Lennox is at it again. They had a class action law suit about this 2007-2015. Began paying out in 2017. We had biannual check up last week. We haven't use air since last fall. We have gas pack unit on the roof. The tech spotted telltale oil dips and checked unit, discovered leaky evaporator coil. He said that they and other Lennox dealers in the area have had more leaky evaporator coils in relatively new units than there should be. He said when parts aren't available before the cooling season has even started and there are fairly long waits as well, that is frequently an indication that there is a problem with certain units that have defective parts.

    The labor and freon will be about $1000 which is a lot to pay when you've already spent more to get a Lennox unit in the first place. I got a Lennox unit in 1999 from the company I use now and was very happy with it. When it gave up the ghost in 2019 I decided to again go with the Lennox. I called Lennox and the lovely ladies I spoke with were very sorry to hear about the failure of the unit. They, of course, said that there is nothing the company do to help me. I think it may be time for another class action law suit. Sounds like they didn't learn their lesson the first time. My suggestion to those of you shopping for a new AC unit. Go ahead, get the cheaper one and put the difference in the bank for any repairs, if needed. No use spending extra to get a so called "more reliable" unit.

    We have a two year old AC unit from Lennox Heating and Cooling. We have been facing issues one after another. Now out evaporator coil is out (had seven leaks) and Lennox is now telling us that the part is out of stock (hilarious) and that they don't have an ETA. Our tenants have been without AC for a week and I'm furious. Lennox is the worst company to deal with, every review I read shows that. Never again! Save your money please, you'll regret it.

    I have a Lennox system about 3 year old. Furnace broke down in extreme cold situation and the installer told us they contacted lennox for a part about 4 weeks ago. The part is still said to be back order..what good is the system when no one can help you when you need them most and your family is suffering. 4 weeks and counting....let's say I lost complete trust in lennox.

    The Lennox HVAC in my attic has developed a coil leak after just over 2 years of living in the home. Andy **, the contractor, installed and maintains the unit. Moreover, they registered my product, which I am not able to register. Only 6 months after the labor warranty has expired, the coil on the unit has developed a leak, requiring them to replace the coil at a cost of $1783.67. I find this to be outrageous. Lennox units have had previous problems with coil leaks. This is a known problem. Why is the company continuing to make products that don't last and cost people money? Andy ** states the part is under warranty, but I have to pay for the labor and Freon. They state that Freon is over 300.00 a pound. This is completely outrageous.

    I installed a Lennox air conditioner a little over a year ago, but the compressor has now failed. Even though this unit is under warranty, and still manufactured, it will take 5-6 weeks to get a replacement. I live in Miami, and the temperature is in the mid to upper 80's. This is very poor product service from Lennox, leaving their customer hot and uncomfortable. Lennox should support the products they sell.
