“HVAC” stands for heating, ventilation and air conditioning and are found in most new homes. HVAC systems may vary depending on their age and brand, but most modern systems are forced-air.
When cooling air, HVAC systems use a refrigerant to cool the indoor air. This air is then cycled back through the home. This process continues until the air in the home reaches the temperature chosen on the thermostat.
Heating air uses a similar process but, unlike air conditioning, relies on gas and a pilot light to create heat instead of using a refrigerant or other chemical. After cool air is heated through the burner system, air is distributed through air ducts until the house warms to the desired temperature.
Regardless of exactly how a home’s HVAC system works, most consumers want their heating and cooling appliance to be of high quality. Whether they need to stay warm in the winter or avoid the summer heat, a quality HVAC system is essential to a homeowner’s comfort. Unfortunately, not all HVAC systems are up to par – leaving some consumers literally out in the cold or stuck in the heat.
Are Lennox HVAC Systems Good Quality?
According to the manufacturer, Lennox HVAC systems have been “engineered to deliver best-in-class comfort and efficiency” and can provide “truly outstanding” results when two or more Lennox products are used together.
Unfortunately, despite these promises, some consumers have reported serious problems with their Lennox HVAC systems. Several consumers have taken to online forums such as the Better Business Bureau to detail their problems with an HVAC system from Lennox.
In September, one complaint detailed a problem with the evaporator coil in an air conditioning system. Unfortunately, the reviewer said that Lennox has failed to get back to them about fixing the problem under warranty.
Another complaint from August said that, since having a roof unit installed five years ago, the homeowner has had a significant service bill each year “without fail.” This year, the homeowner’s system allegedly showed issues with the evaporator coil leaking. Even after spending up to $2,000 each year on repairs, the homeowner was allegedly told they would need to pay nearly $9,000 to fix this year’s evaporator coil problem.
“Every year we are spending 1,000 to 2,000 on repairs and maintenance for this unit,” the complaint revealed. “These are the worst A/C units.”
Unfortunately, problems with a Lennox HVAC system could prove costly – as shown in the complaint above. Repairs can run thousands of dollars with additional money required to resolve damage from leaks or other problems.
Plaintiffs in the Lennox class action lawsuit claimed that these evaporator coils were made with copper tubing – a design flaw which reportedly resulted in corrosion. This corrosion was reportedly caused by a chemical reaction with the coils that lead to microscopic tunnels in the products. As a result, the evaporator coils allegedly leaked refrigerant.
The plaintiffs argued that Lennox should have been aware of this issue and taken steps to fix it, including coating evaporator coils to reduce corrosion and subsequent leakage.
Lennox didn’t admit any wrongdoing but agreed to a class action settlement to resolve the claims against them. The deal benefited individuals who purchased a Lennox brand, Aire-Flo brand, Armstrong Air brand, AirEase brand, Concord brand, or Ducane brand evaporator coil covered by warranty between Oct. 29, 2007 and July 9, 2015.
The settlement provided several forms of relief including a $75 service rebate, replacement of defective coils, and up to $1100 in labor reimbursement for original or replacement coils.
Although this Lennox HVAC class action settlement resolved claims surrounding the company’s evaporator coils, consumers may still be able to take legal action or join a pending class action lawsuit against the company.
Can I File a Lennox Class Action Lawsuit?
If you experienced issues with your Lennox HVAC system, you may be eligible to take legal action against the manufacturer. In some cases, this could mean filing your own lawsuit or class action lawsuit against Lennox. However, you could also be eligible to join an existing case as an additional plaintiff.
Filing a Lennox HVAC class action lawsuit could be your way to secure compensation for property damage and other issues resulting from a product defect. An experienced HVAC attorney can review your case to see if you’re eligible.

If you are a California resident and you purchased a major home appliance within the last year, you may be eligible to claim compensation.
New home that I purchased in 2018 had 2 Lennox units. Within a few years, refrigerant kept leaking. Filling it up each year cost hundreds. In 2023, had to replace the coils in one unit which were still under warranty, but had to pay for labor which came close to $2000. This past month the other unit after leaking continuously, stopped working altogether. Had to replace the whole system for $11000. Never ever getting Lennox again. Surprised that Costco still promotes them.
I replaced a Lennox hvac system with another Lennox in 2014. Last year November 2024, the tech had to put additional coolant in because of a leak. July 16, 2025 the same tech informs me that I have a leak in the coils inside the air handler, which will cost about $3000 to replace. How do I enroll in the Lennox class action lawsuit?
House built in 2016 – Lennox Indoor Coil failure. Original Installer quit handling Lennox. They are trying to get a replacement coil and are being told 2 weeks and Lennox won’t quote a price to then Installer.
Is there another class action lawsuit against Lennnox? My coils failed on a brand new unit within five years of installation. I’d like to join a lawsuit if so.
I purchased a new home in 2018 with 3 new Lennox Ac units and 2023, 1 of the units coil started to leak and needed to be replaced. The coil was covered under warranty but it cost me $900 in labor. Now 8/4/2014, the other 2 units are leaking at the coils. They siad the coils are covered but labor will be over $3000 for 2 unit repairs.
Bought my unit in 2017 just found out the coils need replaced. It is still under warranty but they are saying I have to pay to have it replaced. The cost should be in Lennox because it is there problem the thing needs replaced.
I also purchased a Lenox in 2017 and have had nothing but problems from day ONE! The company even said it’s “Not our fault Lenox sold you a POS.” He didn’t abbreviated either. They have pieced it together like a Lego set. Our other air conditioner went out and when it was replaced I have now found out that Lenox manufacturers their motor. OMG. It too is Banging.

Replacement for Lennox leaky coils should be covered for installation.
Is there another class action lawsuit against Lennnox? My coils failed on a brand new unit within five years of installation. I’d like to join a lawsuit if so.
My could failed too!! What did you end up doing?
I meant to say mine failed too
