Lennox Reviews 

We purchased a new Lennox AC unit through Costco in May 2023 and used a local contractor to install it. Although the unit "works" the model we chose makes an incredibly loud noise every time the compressor shuts off. From day one, we've complained to both the installer and Costco. Both have told us that this is a "known issue" with Lennox and this particular unit. Both the installer and Costco are "waiting on a fix" from Lennox. Sixteen months later Lennox is still dragging its feet on this issue.

FH Furr, Lennox & Costco would not honor their 10 years warranty. I got the very expensive Lennox HVAC via Costco that was installed by FH Furr. The product was a lemon that broke down on the first week of installation & over the course of 6 yrs. When wanting to claim the 10 yrs warranty they said an annual maintenance was required, which was never communicated before. Also, I found online that the product has a coil failure law sue in the past.

had 3 year old lennox air conditioner maintenance on 5/9/24. motor was siezed in less than 3 years. i'm still waiting for my hvac service to received a new motor from another city in my state. my hvac service would charge me $250 to put in a temporary motor until the new lennox motor arrives. this is a charge lennox should be responsible for & absorb. the unit is still under warranty BUT i still have NO air conditioning after having a new unit for less than 3 years. i refuse to pay $250 in the meantime for lennox's failure as a company. i have no firm date as to when i will have a working air conditioning system again.

Incredibily BAD.
Just a simple mistake and they "try to sell" an intervention of their technicians.
NO technical information can be gotten by them in BeNeLux.
I highly recommend to buy somewhere else.
If this is their way of "SERVICE TO CUSTOMERS" one good advice: turn the page.

Our furnace stopped working on a cold day, so I called the HVAC contactor that installed the unit during new construction 18 months ago. The service tech found that a pressure switch wire had disconnected and wrapped around the inducer motor. When asked how that could happen when the unit has never been opened or serviced, I was told that the only explanation was "poor workmanship" at the point of assembly. The wire was reconnected, and I paid the $225 service call. I contacted Lennox several times by email and phone about splitting the cost of repair only to receive the run around and finally a denial based on a warranty technicality argument. I now will pursue small claims court action with the support of the installation contractor. Junk product, fake customer service!

Purchased a home in July, 2023 that is three years old. I’ve had to replace coils already twice now in this home. Lennox will not re-imburse me for refrigerant nor offer to have their unit inspected to fix the root of the problem. To my knowledge the previous owners had to replace coils as well. This should not be happening in a unit three years old. I’m already out thousands of dollars and cannot get anyone to off set the cost of their faulty system.

Lennox. They play games. Simply trying to look up a serial number and you have to jump hoops to even get that far. That immediately raises a lot of red flags. No reason for this. No wonder I see so many bad reviews

As a field tech and a company owner ,I must say lennox has the worst customer service both in person and on the phone . I've had problems with their method for years and I'm sure we are not alone ,today I decided to write :
parts are mostly out of stock and reps are always frustrated for obvious reasons ,
phone calls takes forever to be answered, It's not acceptable to hold homeowners or the techs on the phone for over an hour before answering the calls.
there seem to be only 1 or 2 tech support on the phone which explains the long hold times and when they finally answer with frustration they have no answer for some of the questions especially with the newer units and accessories.
not enough data and info in manuals adds to this mess.

maybe try learning from successful company in client service.
its been 58 min till this very moment that I'm on hold for tech support .

I'm going to switch to Daikin, rather work with normal unit with an excellent client service over a more expensive but disrespectful, disappointing badge
I'm pretty sure my clients will enjoy the real warranty and support and constantly available parts .

My HVAC rep entered my rebate info incorrectly and Lennox rebate customer service although kind over the phone and willing to"expedite" my several requests from me via several phone calls, online forms and having my HVAC rep call his Lennox rep, to correct the info. No one from Lennox has ever called me back as promised within 48 hours in any instance. I am not able to log in to see my rebate status and the address is incorrect. Lennox has managed to provide exceptionally poor customer care in failure to follow through.

Installed new Lennox HVAC in Aug 2016. icomfort wif thermostat (Lennox's own thermostat) screen went blue and no longer works. Call lennox and they told me tough luck as out of warranty after 5 years. Looking online, many people across the country had the same issue. New thermstat is $800 - this is unacceptable.

NEVER BUY A LENNOX. After installing a CX20 system in 2015 we've had to replace the Thermostat, the fan, and now the evaporator coils. Just go to Home Depot and buy window units. Save the headache and the money. The response from Lennox was sympathy. They were very sorry their products keep breaking and I had to pay thousands of dollars in labor costs to replace parts under warranty. Do your research and buy something else. Lennox manufactures subpar products.

I bought a Lennox air conditioner in 2021 and at 2 years the compressor went out. The bad thing about the dealers is that they call Lennox to get approval on a warranty claim and then they have to wait for Lennox to call back the same goes for finding a unit to replace. They don't do this for cars. Waiting for approval on a claim. How absurd. I've had Lennox previously and it worked great for 20 years but I will never buy LLennox again as I think their whole process of building and servicing has changed. Like everything else it is manufactured in China and made cheaply. Service attitudes are terrible and non-responsive. All of the makers are bad and Lennox is supposed to be the best of the worst. Read reviews before you buy and then pick your poison.

We got Lennox Heater and Air Conditioner in less than 2 years. Based on the contract, labor and parts are free of coverage. The coil leaks and all the refrigent gone. The Lennox dealer said they will replace the coil and only covers 3 lbs of refrigent but the coild needs over 7 lbs refrigent in total. I contacted Lennox by email and their customer service rep emailed me back and told me that Lennox only covers the parts, not the refrigent.
My question is, the product has issue and caused the failure. Why Lennox customers have to pay for the cost, even everything is under warranty.
For those who are looking for Heater and/or Air Conditioner product, be careful of Lennox products. Their warranty is kind of no warranty.
If there is zero star, I'll select it.

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.

Spent close to 18k in replacing my entire HVAC system to bring it up to code with CA low nox standards. There were some issues early on but easily solved by the techs. The system is now 2.5 years old and I have had no heat in my home since October. The Lexxox rep in my area will not come out until every part in both furnaces has been replaced by the techs. The last of the parts were replaced last week and it was at that time I was informed by the techs that the Lennox rep was busy and may not be able to make a visit to inspect this situation until after the holidays and he won't specify if by holidays he means Christmas or New Years.

I had my Lennox for eight years , then the evaporator coil stop working . Call tech to check , gladly was under Warrenty however the part is not available nation wide . When you call Lennox customer affairs and waited for hour and half the usual answer is NO ETA , “I am sorry but we don’t know when the part is ready” , or call your tech to provide you some info . Unfortunately , no direct answer to the customer and no alternative option to help . When you ask to replace the unit , the answer is WE are working on your par so when you ask when is ready , the answer is WE don’t know . Calling Lennox is just a waste of time , also when you compliant to a manager ( Manager is always not available) , you get directed to voice message and they never call you . It is the worst service I have EVER encountered . Currently waiting for my part it could take from 3 weeks to 3 month . Explained to them I have medical condition but no understandable response . I have notice they have bad history on coils but NO great handling or reaching to customers for notifications about those issues . Don’t call customer service b/c will get nothing , or they will say call your tech for details . So when you call the tech no info from Lennox to the tech . Huge gab in communications . I will do more research about the law suite on coils to find out if I can do the same after reaching to a lawyer .

It was the worst $3,500 I spent in my life. In simply doesn't work in Hot days ! I had Goodman before, way better quality and yet cheaper!

OH, and the cherry on top, a new thermostat to replace the defective one: $2,000

OK, I've had enough....spent $16K on two units only to have to deal with these thermostat "PATCHES" every 3-6 months. FOR past 7 + yrs.!!!

Why wasn't I offered an option to replace and get the new thermostats???????????????? 5 yr warranty on old thermostats, 10 yr. on new....

Again, 90 degrees in Austin... no AC called Lennox 3 times spoke to 4 nice employees (about to call a fourth time)... 3 calls to local repairmen.

Todays Lennox case # 2211043

To anybody who asks me: "AVOID LENNOX"

Worst HVAC company in the history of the world. They don't stand by their equipment. They replace junk with more junk that breaks again and again. Customer service is atrocious whether by phone or social media.

I have a Lennox air conditioning system with a 5 year warranty and have a leaking evaporator coil that is covered under the 5 year warranty. My a/c service provider and I have spent several weeks trying to get the new warranty evaporator coil. I was originally told by consumer affairs that they had warranty evaporator coils stored in a warehouse for warranty claims, but am now being told it is on backorder and there is no eta after waiting several weeks and having no air conditioning for months. I have spoken to customer affairs multiple times and have made several attempts to get the situation resolved including trying to get ahold of a supervisor or manager with no such luck. I have spent countless hours on hold and feel Lennox customer support is by far some of the worst I have ever encountered. Lennox is not honoring their warranty and is refusing to help resolve the situation. They should not offer a warranty they can not honor.
