310 Lennox Consumer Reviews and Complaints

Original review: Jan. 17, 2018

I bought an expensive outside unit for a new home. The unit had a rebate as part of the purchase. Rebates normally come in the form of a check which can be deposited. In Lennox case it is provided on a debit card that is only good for 6 months. The card states that it is active but there is an expiration that is not noticeable. If you don't use it on time the funds disappear and the website that I used to verify says it cannot be reissued. I saw another complaint about the 2.95 cash fee but this is more significant. In this case Lennox can reclaim rebate money that it owes a customer. Be wary and use it fast if you get one. This is a great business scheme for a business to take money that it owes back and add to their bottom line. I do wonder how many others are affected. I plan on adding this complaint to as many sites as possible to ensure that the public knows about this issue!

Had difficulty connecting my Lennox iComfort WiFi thermostat to WiFi. Melissa from technical support informed me that Comcast updated their firmware in Oct 2017. She took me through step by step on the thermostat and on the Comcast Gateway settings, and was very pleasant and knowledgeable. The thermostat now connects to the WiFi. The only downside is that I will burn fewer calories not running back and forth to the thermostat.

HVAC product quality is the worst I have seen. This company uses Indian R&D center and their product design is poorest in the industry. The AC makes loud noise, the heater igniter goes bad every year!

Have an 8 year old Lennox Heat Pump. Stopped working. Called repair service, who ordered part online with rush shipping. When it did not arrive when supposed to, repairman called. Part was not in stock in that warehouse. Was told that no one does anything about it until someone calls. Repairman then called and was told that it would take two days to enter it into the system, then it would take two days to ship (wouldn't do it next day air). Didn't seem to care that we haven't had a furnace in November for a week, and now it's going to be almost two weeks.

New home built by Schumacher Homes, 2017. Installed new Lennox unit before we ever moved in. The first day of installation, the furnace was running and would not shut off, it was hotter in the house than it was outside in July. We turned the power off to the unit. We moved into our new home at the end of July and two days later the AC unit quit. Two service calls later and new parts and it was working fine until last week when the emergency heat kicked on and would not shut off, the temperature outside was 62 degrees, the emergency heat should never have turned on. The thermostat was set to 66 degrees and the temperature inside the house was 73 degrees and climbing. We had to shut off the breakers once again.

We are not complaining about the company who installed the unit, they are wonderful about getting our system running properly. We are warning anyone thinking about installing and Lennox to reconsider. I want a new system installed, because the one that I have now is 3 months old and I have had 5 service calls already, parts replaced, thermostat replaced and lots of aggravation. We now refer to it as our "Lennox Lemon". Very dissatisfied customer.

Lennox issued me $350 rebate in the form of a prepaid Visa card. It is intended for use to purchase products from retailers. That means I lose out on bonus points from the American Express card that I would normally use, thus it costs me money to get my rebate. I can use the card to withdraw cash from Visa ATM's, but Visa charges a $2.95 fee for each transaction, in addition to the ATM fee. No matter how I use the prepaid card, it costs me money! Robbery used to be against the law.

Original review: Oct. 29, 2017

We moved into a new home in December of 2014. The home had a Lennox Air Handler installed for AC/Heat. We began having problems within 6 months! In June of 2015 had to have a new controller. In July of 2015 had to have a new control panel. In July of 2016 had to replace evaporator coil and $600 of leaked Freon (only coil covered under warranty not the thousands of labor or Freon). In August of 2016 another Freon leak. In October of 2017 another hole in the evaporator coil and leak of all Freon, had to have a new coil and new Freon. Again only the coil itself under warranty, still had to pay $2500 in labor and Freon.

Lennox is unresponsive to our attempts to contact them. We have been trying to talk to them since the first incident and no one will reply!!! Lennox is a bunch of crooks and they do not honor their work. We have almost paid for our air conditioning system twice and we have only lived in our home for almost 3 years. Their BBB rating is a complete joke. How can you have an A+ rating when 80% of your comments are negative!

Original review: Oct. 27, 2017

I have had to replace my air handler coil 3 times in the last 4.5 years. I am very disappointed, angry, and financially out for the cost for the last coil replacement. My service tech showed me the coil which was rusty, had the seals disconnected and falling away from the coils, and had a part that controls the refrigerant flow stuck at 50% flow. I called Lennox to seek help in making their Heat Pump new in 2013 work properly. Finally a Customer Affairs representative (Maria **) called me and asked to talk through my situation. I returned the call a few hours later but no answer. For 5 weeks I have called and left messages, sent emails, called the main line and was transferred to the representative's number, and even asked if anybody else would help me... All in vain. No return calls, no follow up, no emails, no nothing.

I believe Lennox provides quality HVAC products but they have no customer satisfaction focus of any kind. I will never purchase or advise any of my friends, business associates, or family to even consider Lennox. What does it take to help a valued customer address and resolve a product issue? Evidently that is way too much effort for Lennox Customer affairs...

Smith's Heating and Air in Charleston, SC installed the Lennox HVAC system in my new home. For 10 months I've been trying to get them to do something about the noise of the heat pump. They have come to the house, but have done nothing. I contacted the manufacturer (Lennox) 3 times and they have not responded to my complaint. This is a warrantied unit. I filed a complaint with the state's consumer protection agency and Smith's has not responded to them. Lennox was suppose to come to the house about a month ago, but canceled the appt. Smith's contacted me a week ago and wanted to set up another date, but I will be out of the country. Smith's has not gotten back to me to try to schedule another date. This unit has a 10/15 year warranty, but what good does a warranty do if both the manufacturer and dealer ignore you.

Purchased a Lennox AC unit for the house 06-2015. In 10-2016 had to have 3 lbs. refrigerant added. In 07-2017 the unit quit cooling. Service company called. Found 2 leaks in the coil. Had to replace coil. Unit has always been very loud. Will never buy Lennox products again. Very unsatisfactory.

Outdoor unit was making noise and was told there was a leak. Coil may or may not need replacing. Looking at $900 to $1600 worth of repairs for a 2 year old unit. This is absolutely absurd. How is Lennox allowed to even sell such sub-standard units? Apparently there is a class action lawsuit against them. I hope they go bankrupt paying back everyone who purchased their products in good faith only to have them fail so quickly. What a lemon!!!

Original review: Oct. 5, 2017

The unit that is in my home is now 16 months old. (3 ton Heat Pump) The main component of operation for cooling and heating the compressor began leaking all of the refrigerant out due to a crack in the head of the compressor at the suction outlet side. The part is under warranty. However, Lennox is and will not assist in covering the cost of the labor and refrigerant cost. You would think that since it a failure due to a manufacturer defect as my repair technician advised that they would as a one time gesture cover this expense. However, they say that "parts fail and that is why we cover the parts only." I thought that Lennox took care of their customers better than that, but come to find out no. They keep telling me, "you should buy a maintenance agreement with your service company." After the 4900.00 expense of the install who can afford the extra money out of pocket.

So, with that being said, if a consumer is reading this review, I would recommend that you purchase another brand because Lennox does not care enough about their name or their customers to step up and take care of issues like this when it is clearly a manufacturer's defect in the design of their compressor. I have attached the model and serial of the unit as proof...

Original review: Sept. 22, 2017

I am the second homeowner of this 5 Ton heat pump system. The system was nestled in 2011 and the installer failed to install a drip rail to contain the water inside the air handler. The design for my particular air handler (model CBX27UH-060-230-6-03 ) used a drain pan that did not cover the length of the internal coil and the drip rail was added only to this model to catch the excess water and direct it to the short drain pan. The unit had a maintenance program for over 3 years from One Hour heating and cooling and never revealed the problem.

I have included picture of the internal workings of the air handler. Since I was the second homeowner Lennox would not warranty any of this damage. The company that installed the unit is no longer in business so I can't go after them for any help. The company who I paid for the maintenance program refuses to take any responsibility. So I am removing the Lennox system and replacing it with a new system even though it is only 6 yrs old because I can't get any assistance with my issues from anyone.

On a two-year-old unit after a power outage it would not start and it has a defective fan motor. Lennox is not standing behind their warranty. Wanted to charge us $800 to install a generic fan because they claim their company has no parts anywhere in United States.

Purchased a new AC from Costco/Parker and sons in Scottsdale AZ on July of 2012 for $6500.00. The unit suddenly failed on August17, 2017 with large leak of 410 refrigerant from outside cooling fins and from piping. According to contractor this problem is common with Lennox units in Phoenix AZ area. QA/QC of unit is poor especially in cooling fins on outside unit. Poor construction of metal on fins allows leaks and unit failure. The part is under warranty BUT labor to install new part is $1688.00. I am very disappointed with quality of this AC unit.

We bought a new Lennox Ac/gas heat unit Model 13GEP3007. In less than 2 years, coil developed freon leak. Service tech quoted me $1000 for labor alone which we were responsible for and stated that a new coil part is under warranty. With the recommendations that Lennox was a superior built product, we really were upset that such a new unit was already needing expensive repairs. Tech told us that the Lennox coils were of poor quality and that there were a lot of complaints regarding this repair. He told us of a class action lawsuit against Lennox for this defect.

1 week after the builders warranty was up had to replace air handler motor which cost me $449 for labor and then again 9 months later a circuit board shorted out on heat pump which cost me an additional $479 of pocket. Called Lennox customer service and got no satisfaction. Would never even purchase a Lennox product again.

Original review: July 21, 2017

I bought this newly-built house on Dec 27, 2013, installed with two brand new Lennox whole AC/Heating Units, one for upstairs and one for downstairs. The unit for upstairs stopped working this past Sunday, 7/16/2017. Completely unexpectedly, and without any warning at all, there was no air conditioning in the upper floor of our house, and this is in the middle of summer, so it is highly inconvenient and uncomfortable for us. We could not get someone to come out to take a look at the AC unit until the next day, and we discovered that there was a copious amount of refrigerant leaking from the condenser coil of the broken unit. Due to the complexity and length of the condenser coil, we were unable to pin down the leak, and it still requires further work. The house was brand new, and the units were also completely new, so that means this unit has broken in less than 4 years.

This is absolutely unacceptable, and as a customer of Lennox, a supposedly high-quality company, I am very disappointed. I expect better, and additionally, I was promised better. For comparison, in our old house, which was built a much longer time ago, the AC/heating system was from a small company and worked perfectly for 11 years. An old unit working for 11 years versus a new unit only working less than 4 years is ridiculous. There is a statement in your website: A life with Lennox comfort systems is as close to perfect as it can get. However, we are experiencing 85F-90F in our home at upstairs because Lennox AC unit stops working due to defect of condenser coil. I can only conclude that Lennox is inadequate and making false promises about the quality of its machinery.

We were told an estimated labor fee to replace the deficient condenser coil would be around $1,200.00. Again, this is a shocking amount to pay for such a new unit. Our warranty covers labor for only the 1st year, and parts for only 5 years. The original home builder, Pulte Company, chose the Kaiser Company as a dealer and installer. Due to the contract, I also didn't have any choice in choosing the installation company for the Lennox AC/heating system, and furthermore, I was not given the possibility of purchasing any other kind of warranty. I called Lennox customer service department and explained our situation, ask for extended warranty program, they refuse us to join now.

They don't have any confidence about their products, plus terrible customer service. They play the trick between home builder and dealer, sell large amount of defect/under quality products to home builder and dealer, the homebuilder didn't give homeowner any information about extended warranty information (10 year cover labor and parts). Later on homeowner will pay large amount money for the repairment of Lennox defect products. Lennox should close their manufacturing!! I saw many customer complaints AC unit broken in less than 3-4 year, I couldn't believe such horrible company still exist in USA!!!

The Lennox a/c system in our home is 2 years old. We had to recently replace the TXV valve and was also told we need a new compressor. Both of these parts have a 5 year warranty. Nowhere were told that the new compressor will only have a 1 year warranty because it is a replacement. Because it is a new compressor IMO it should have a 5 year warranty. The same problem occurred with a family member's Lennox system that is only 5 years old. I thought Lennox was a top of the line a/c system. I do not feel that way anymore and will never recommend to anyone else.

We had a Lennox air conditioner installed several years ago. Immediately, we noticed that it would take an hour or more for the temperature in our house to drop one degree. We own a split-level, so it has nothing to do with the size of our home. We had several people come out to inspect the unit and we're told there was nothing wrong with it. This continues to be a problem. We went out of town for 2 nights and turned the air to 79. We have now been home for 3 hours and it still hasn't dropped the temp AT ALL!!! I would not recommend this brand to anyone.

Chris of Herriman, UT Verified Reviewer
Original review: July 15, 2017

I have nothing but a good experience with my Lennox equipment. I had another company install some equipment before my Lennox equipment was installed and had nothing but issues with it. It eventually died 5 years later, and that contractor consistently told me there was nothing wrong with it. Wrong size equipment, wrong size line set, and improper air flow at the coil. Moral of the story is that the low quality equipment installed properly will outlast quality equipment installed improperly.

HVAC is one of those things where most are dependent on contractors being honest with the customer and most contractors are not. When I was having issues with my previous equipment, it was around a $100 a pop to have someone come out and look at it and give me a different story on what the problem was. I eventually had to do my own research and learn what is right and wrong when it comes to equipment installation. I ended up using a company that was being used to install equipment in a neighborhood where the homes are fairy tale. They were great. My knowledge has saved family members thousands (literally), including my own mom. I don't have a license to install, but I do know what is right and what is wrong.

A contractor that short changes the customer and installs the equipment wrong is the problem. There are a lot of variables when it comes to having the equipment work properly. Using a line set of proper size, having the right amount of cold air returns, where the cold air returns are placed, having proper airflow at the air handler/furnace, along with sizing the coil and condenser properly. All of these specs are based off of living at sea level and most of us don't. So it needs to be adjusted accordingly. Homes where the top level, (not a rambler) gets hot is due to not having proper cold air returns installed. Most contractors skimp on this during initial construction due to it being work to get returns to the top of the house, and don't put any or not enough in.

Unfortunately using a contractor that doesn't install the equipment properly is the problem, not the equipment. After having my equipment replaced at a cost of $11,300 dollars, I have had it in for 10 years with zero issues. The homeowner when paying someone to do the job shouldn't be expected to know what is right and wrong, but unfortunately that seems to be the way the world operates anymore. I have heard horror stories from people where companies have intentionally sold people new equipment when there was nothing serious with what they had. I only trust my original installer, and still hover when having a maintenance done. Be cautious when having your refrigerant checked too, because each time you do you're losing a little. It shouldn't be losing any over time.

People that are having issues with losing refrigerant it is due to a leak somewhere in the line. The line should have been tested for leaks before charging. That contractor that you trust may be your problem. It isn't the equipment. And I will say it again, low quality equipment installed properly will outlast quality equipment installed improperly.

We closed on our NEW Pulte home on Oct 11, 2011. On Aug 8, 2016 we had our first a/c issue with Lennox. The upstairs unit was not cooling sufficiently. Tech came out and recharged the unit adding 2 lbs of refrigerant. $209 service charge. On May 19, 2017 same issue with a test for a leak. $430 service charge. Go away on vacay for a couple of weeks, come back, same issue. Another call. This time no service charge. Couple of days later discovered a leak in the evaporator coil. Cost to replace $2,422.64. Really?

I call Lennox. Five year warranty. "You are out of warranty. Sorry, bye." This all started on 8/8/16, within the 5 year warranty. Is there a little man in the evap coil saying, 'hey look at me, I am leaking here!' It takes time to sort things out. Let alone the A/C season ends sometime in Sep and begins again around May. So for the five years and nine months the unit is installed it gets used maybe six months out of the year. So in essence my system is two and a half years old, not five.

Here is the kicker to all of this. The paperwork and warranty card are tucked away next to the unit. I didn't know the units needed to be registered. I have two units. Where is the second set of paperwork? I don't know... not anywhere to be found. I call Lennox. They tell me to go to **. The deadline is 2/1/16 or 60 days AFTER your original coil is replaced. Great. Is there anyone to talk to at this website? No. Do I have some questions? Yes. Is there an email address to address my questions? Yes. Will I get an answer? Well, it has been a couple of days so far and nothing. I am not holding my breath.

Why doesn't the builder leave behind a folder for the new homeowner that is nuclear orange in color. The folder should say, "Things you must take care of immediately!" In that packet is a checklist with all of the warranty cards that need to be registered. This way with all of the chaos of moving in you know you have to take care of something important. NOW!

So now I go after my builder. After all Pulte states "Over 65 years of experience go into the building of every Pulte home, and our construction standards are set high to meet expectations. When we build your new home, we follow a process that meets high standards of quality and attention to detail." Um... nope. They should say "Over 65 years of experience go into the building of every Pulte home and we have learned over the years that we can squeeze our suppliers extremely hard to meet Wall Street's quarterly profit expectations. You can count on getting mechanicals for your home that look good and will last just long enough to be out of warranty. By then we are out of the picture." So what did the builder say? Same thing. You are out of warranty.

Final thoughts. This is a great country. But unfortunately we are racing to the bottom. No one wins there. I would rather have a bullet proof HVAC system (25 year warranty) installed in my house. Yes, it will cost them more, but they can pass that cost on to me. How am I going to know how much they paid for the system? In doing so their name becomes synonymous with quality. Now... I will never do this again. REMEMBER WHEN WE BUILT THINGS THAT LASTED? Damn shame... P.S. My wife told me she didn't want to buy a mass produced house. "They will cut corners everywhere they can." I should have listened to her. I owe her that statement for the grief this overall experience is causing her.

I made the mistake of having two Lennox systems in my house. Last year, the coil in one had to be replaced. This year both units went out in the same week. One of the units (basement) had a leak in the outside unit. Had to pay $225 to get Freon since it was a weekend. While the part was under warranty, labor was not. So to replace this item was $595 in labor or $525 to repair. I really wanted to do the $595 so Lennox would feel the pain but the installer said I would probably get another lemon that had to be repaired the next year. He said it was probably manufactured on a Monday or a Friday, which had the highest failure rate.

The other unit (main house) had the coil go out. While the 'part' is under warranty, installation is $1,000 total. Had to pay $325 to find the leak. This coil was just replace last year too. I cannot keep replacing these annually. I found an installer who said NOT to buy the copper coil, only allow installation of the aluminum. They are supposed to be out this month. My installer says no. I'll be over $2,000 in repairs before this is over and probably have to do it again next year. Currently, I have now been on hold for over an hour (65 mins) waiting on a representative to find out if aluminum coils are available anytime soon.

I had this Lennox 13ACX unit just for 19 months, and it was freeze up in July. I call the installer, they came and got operating pressures at 350/160 (Liquid/Suction) at 81 degree day. The technician told me the low side pressure is high, then he changed his mind after talked to his boss, and said the system is normal. I then download the hvac manual. On the manual, the pressures for my model are 304 / 134 at 80 degree, and 354 / 142 at 90 degree. I was trying to call Lennox to get the normal work pressure range and no one seems understand. It was a unbelievable experience. Hope someone from the manufacture could contact me.

After 3 years of use I had to replace the coil in the Lennox A/C unit. I paid the labor for the installation. Exactly 2 years later, 2017, I had to replace the replacement because of a leaking coil. This time, I had to again pay the labor for replacing the coil. The second time, the coil was replaced with an aluminum coil.

Do I have any recourse against this company?

We had a Lennox system installed in our house. 31 days later it's blowing hot air. We had the guys come out check it out and what a surprise the exchanger they just installed 31 days ago was bad and needed replaced. I called the people and they said my 30 day warranty was expired. As you can guess, I was extremely mad. They eventually came out and replaced it free of charge. The tech actually said that Lennox was now getting their parts from Mexico and were junk.

Fast forward 3 years and our AC is acting up again. The tech said it had no freon and there was a leak. Go figure, only 3 years after replacing the exchanger, the whole copper line running out to the outside, and the outside unit... It's broke again. Lennox is crap. Never buy Lennox unless you want to replace your whole system every 3-5 years.

My husband and I had our house built in October of 2015. Our Lennox air conditioner stopped working in June of 2017. We had to pay hundreds of dollars to have the coolant put back into the unit just for the air conditioner to stop working the very next day. We have a two-year-old son who has a bleeding disorder and requires medicine and a lot of medical equipment to be kept in our house. We cannot allow our house to get very hot. We are fearful that even if we pay another several hundred dollars, the air conditioner is going to stop again the next day. Having this air conditioner in our home has put our son in danger because his extremely expensive medical supplies and medicine cannot get hot. Not to mention, it is not safe for a two-year-old to be in an extremely hot house.

We did our homework, Lennox was the best, right off the start. The first year 2009 had to replace part in heater, summer time had to replace part on air unit. Second summer A.C. had to have part replaced, year 5 A.C. unit had to have new motor!! Year 9 this is right now coils have a leak, not covered under warranty $3000 and next year is year 10 end of warranty altogether. $15; to 19 thousand dollars to replace both units. What a bunch of **. 10 yrs and every year something had to be replaced. I will never buy another LENNOX ANYTHING or recommend them.

My husband and I purchased our Lennox Xc1403623007 air conditioner three years ago. We replaced an old Carrier air conditioner. We spent over six- thousand dollars for it. We have already experienced a leak and the protocol is for the air conditioner service people is to inject with a sealant die and then add for Freon. That cost us eight hundred dollars. I'm aware that there is a class action law suit against Lennox for faulty coils. You don't get anything back unless they change your coil out and you still have to pay for labor and Freon. What a JOKE. They only offer seventy-five dollars for a service fee and five hundred for labor if the coil is actually replaced. So, now we wait to see if the sealant works and if it doesn't it will cost us labor and freon. That will be another eight hundred to one thousand dollars. I WILL NEVER BUY A LENNOX AGAIN.

I live in Houston, TX. We have a new house in which a brand-new Lennox AC system was installed in 2011. After a repeated failure of the evaporator coil, I decided to take this issue further and write to the general public in hope that enough complaints would make a difference. In July of 2014, we had the evaporator coil burst and leak. We paid $1400 for this issue to be resolved. Just a short amount of time passed and here we go again with the same issue. Just this Sunday, the AC stopped working yet again due to the exact same issue. The evaporator coil has a quarter of an inch hole in it and the refrigerant leaked fully! We are slammed with another round of huge costs.

I called Lennox customer service and they said the part is under warranty and they will provide another coil. However, they are not responsible for the refrigerator, labor and etc costs. I tried to explain that it is not the customer's fault that a manufacturer's part failed and brought an array of costs (and not once, but twice!). I am not only talking about monetary costs, but also huge discomfort since we have no AC for the second time around in Houston and it is 97 F inside, but also transactions costs, our cost of time spent and finally huge environmental cost since leaking refrigerant is highly potent greenhouse gas!

And needless to say, I am furious. A young person trying to make a living will not settle on paying $1,400 each time this happens. A quality AC unit is expected to last at minimum 10 years. And because of Lennox' faulty equipment, it keeps on failing every 2-3 years! There is class-action lawsuits everywhere, bad reviews, but the company does nothing to mediate this problem.

These are dangerous for the environment and for people who may inadvertently wind up with mercury in their food or water supply. Lennox participates in a program run by the Thermostat Recycling Corporation, which is a nonprofit organization that facilitates the collection and disposal of mercury around the United States.
