Lennox no longer manufactures residential generators. Customers who own Lennox generators are instructed to contact the dealers that sold the generators to obtain any available warranty information.
Product guides and brochures are available for downloading on the Lennox website, which offers customers additional information about residential generators. The standard warranty for most generator models includes a five-year warranty for parts and a two-year warranty for labor.
Ten-year extended limited warranties were made available to consumers at the time of purchase. The warranty only applies if the generator was restricted to use in a residential application. Service is provided through the original Lennox dealer.
