This website contains information regarding a proposed class action settlement that has been preliminarily approved by the Court in Thomas v. Lennox Industries Inc., United States District Court for the Northern District of Illinois, Eastern Division, Case No. 13 CV 7747.


A Settlement has been reached with Lennox Industries Inc. ("Lennox") in a class action lawsuit about whether it manufactured and sold defective evaporator coils. An evaporator coil is a part of an air conditioning system or heat pump system in the cooling mode. Lennox denies all of the claims in the lawsuit, but has agreed to the Settlement to avoid the cost and risk of further litigation.

For more information about the Settlement, please review the Class Notice.


All U.S. residents who, between October 29, 2007 and July 9, 2015, purchased at least one new uncoated copper tube Lennox brand, Aire-Flo brand, Armstrong Air brand, AirEase brand, Concord brand, or Ducane brand evaporator coil, covered by an Original Warranty, for their personal, their family, or their household purposes, that was installed in a house, condominium unit, apartment unit, or other residential dwelling located in the United States.

Original Coils may have been purchased separately, as part of an air handler, or they may have been included as part of a Packaged Unit.

The Settlement Class does not include subsequent purchasers. To be a member of the Settlement Class, a claimant must have purchased at least one new eligible evaporator coil. Purchasers of newly built homes with new evaporator coils already installed are eligible.
