All Coleman gas furnaces come with a limited warranty on all parts as of 2015, but the specific terms of the warranty vary from model to model. The Coleman Echelon CP9C and CPLC gas furnaces feature a 10-year limited parts warranty and a lifetime limited warranty on the heat exchanger.
In order for the customer to qualify for the full warranty, it is necessary to register the product online within 90 days of installation. If the customer fails to register the product within the specific period, the 10-year parts warranty reverts to five years, while the lifetime heat exchanger warranty reverts to 20 years. Many of the other models of Coleman gas furnaces, such as the LX Series and the TG9S Comforter, feature the same 10-year limited parts warranty, but only a 20-year limited warranty on the heat exchanger.
Although most of these warranties only cover the cost of parts and not labor, Coleman also offers its Performance Promise Plan in certain situations, such as when buying a matching Echelon heat pump or air conditioner along with an Echelon furnace. The Performance Promise Plan covers the cost of both parts and labor on any necessary repairs for a period of 10 years.
