The lawsuit alleges that Goodman and Amana central air conditioning units sold during this time frame contained defective evaporator coils that improperly and prematurely rupture and leak refrigerant (a.k.a. Freon), which in turn causes the air conditioners to stop functioning properly. It also alleges that Goodman has known about the defective evaporator coils since at least 2008, but that the company has failed to inform consumers about the problem, issue a recall, or take other corrective measures.
