SPOKANE, Wash. — Avista Utilities has announced its new Manufactured Home Duct Sealing Program, which enables qualifying customers in Washington to have their home’s ductwork sealed and receive other energy efficiency products at no cost. Avista said the service, a $500 value, can help customers save up to 30 percent on their energy bill. The program is scheduled to run through the end of June 2013.

“Stopping heated or cooled air from escaping your home is an immediate way to reduce energy use and increase your comfort. Ductwork is typically located in a crawl space or attic, so a manufactured home could be leaking air without the resident realizing it. And that drives up energy bills,” said Chris Drake, Avista energy efficiency program manager.

To qualify for the free Manufactured Home Duct Sealing Program, a resident must be an Avista electric or natural gas customer in Washington living in a manufactured home that:

• is heated primarily by a forced air furnace;

• has ductwork outside the heated space (in attic or crawl space);
