Our most efficient air conditioning and heat pump units offer Lifetime Limited Warranty* protection for the compressor to the original, registered*, single-family, homeowner of a properly matched system. Additionally, our most efficient furnace units offer a Lifetime Limited Warranty* protection on the heat exchanger to the original, registered*, single-family homeowner of a properly matched system.
