Puget Sound Energy is offering electric customers who live in manufactured homes and use electric forced-air as their primary heat source the chance to seal up leaky ductwork and receive other energy efficiency upgrades for free.

The service offered to PSE customers in Carnation, Issaquah, Fall City and surrounding areas has up to a $500 value per customer and could reduce their energy bills by approximately 30 percent.

A large number of older manufactured homes likely have leaky heating and cooling systems that have to work overtime which results in higher energy bills. The program helps customers who live in manufactured-homes install energy-efficient measures to increase their comfort and manage their energy bills.

A certified specialist will seal the ductwork, as well as provide free on-site installation of Energy Star-qualified compact fluorescent light bulbs in high-use areas such as kitchens, living rooms and bedrooms. Customers also receive air filter replacements and an energy-efficient showerhead.

To qualify, those living in manufactured homes must be PSE electric customers and use electric forced-air as the primary heat source. Eligible homeowners cannot have taken advantage of previous manufactured home energy-efficiency upgrade service.

UCONS representatives will be going door-to-door with flyers to discuss the service with PSE customers. PSE customers can also request the service by calling UCONS at 1-800-828-8440.
