Lennox Evaporator Coil Settlement: What It Covered, Why It Is Closed, and Options for Leaking Coils Now

An evaporator coil is the indoor part of a central air conditioner or heat pump that absorbs heat from the air. The class action, filed in 2013 in federal court in Chicago, alleged that Lennox manufactured and sold defective uncoated copper tube evaporator coils that could leak refrigerant, leaving homeowners to pay for repeated repairs.

Lennox denied all of the claims and agreed to settle to avoid the cost and risk of further litigation. The court preliminarily approved the settlement on July 9, 2015. Judge Sara L. Ellis entered the Final Judgment and Order of Dismissal on December 9, 2015, certifying the settlement class and approving a fee and expense award of $1,250,000 plus $2,500 service awards to each class representative.

Unlike a cash fund, the settlement worked as an expanded warranty and reimbursement program, with benefits handled through independent Lennox dealers and the settlement administrator, Kurtzman Carson Consultants. For other home equipment claims, see our LG refrigerator lawsuit and GE washer and dryer lawsuit pages.

The settlement class was U.S. residents who bought, new, at least one uncoated copper tube evaporator coil from these brands: Lennox, Aire-Flo, Armstrong Air, AirEase, Concord, or Ducane. The coil had to be:

• bought between October 29, 2007 and July 9, 2015 (the class period), separately, inside an air handler, or in a packaged unit;
• covered by an original Lennox warranty;
• bought for personal, family, or household use; and
• installed in a U.S. house, condo, apartment, or other residence.

To get any benefit, the original coil had to need replacement within five years of installation. Buyers of newly built homes with the coils already installed were eligible, but later owners of a home, called subsequent purchasers, were not. Coated copper and aluminum tube coils were not in the class.

Benefits depended on how many times a coil failed:

Benefit	Who got it	Value
Service rebate	First replacement within 5 years	$75 toward future service
Replacement coil warranty	Replacement coil failed	Coated copper or aluminum coil
Labor and refrigerant	Two or more replacements	Up to $550 each

The $75 rebate was not a check: it was a form redeemable for one year for service from an independent dealer listed on the settlement site. If a covered replacement coil also failed, the claimant could get a coated copper or aluminum tube coil plus up to $550 for labor and refrigerant, with that warranty lasting up to five years after the replacement was installed. Reimbursement of up to $550 per eligible replacement required at least two coil replacements; one replacement alone did not qualify for cash.

No public report shows a total paid or an average benefit. Our guide on how settlement benefits are divided explains why warranty-style settlements are hard to value.

Event	Date
Preliminary approval	July 9, 2015
Opt-out and objection deadline	November 11, 2015
Final approval	December 9, 2015
Main claim deadline	February 1, 2016
Late replacement claims	60 days after replacement

The claim deadline was February 1, 2016, or 60 days after the original coil was replaced, whichever was later, as long as the replacement came within five years of installation. Because the class period ended July 9, 2015, that five-year window closed for the last covered coils around 2020, and the replacement coil warranty ran up to five years beyond that. As of September 2026, the settlement website is offline and the program is effectively complete.

If you missed this settlement or your system was installed after July 2015, these steps apply:

1. Check your warranty. Find your model and serial numbers, the installation date, and whether the product was registered, then read the written warranty for what it covers (parts, labor, or both).
2. Get the diagnosis in writing. Ask the technician to note that the evaporator coil leaked, the refrigerant added, and the coil type (copper or aluminum).
3. Keep the failed coil or photos and every invoice, in case a claim or lawsuit develops.
4. Know your warranty rights. The federal Magnuson-Moss Warranty Act and state law can help when a written warranty is not honored; see our Magnuson-Moss explainer.

Separately, a proposed antitrust class action, Berg v. Robert Bosch, LLC, filed in federal court in Michigan in March 2026, names Lennox among seven HVAC makers accused of conspiring to keep equipment prices high. That case is an allegation only and has not been certified or settled.
