    Are you paying to heat your home or your crawl space? If your ducts are leaky, you might be doing both. Our duct sealing program can help you find and fix leaky ducts.  If your ducts are leaky, sealing them will cut energy waste, improve air quality, and lower your energy bills, and you can earn a PUD rebate for the project.

    Eligible Customers

    • All PUD customers with forced air electric furnaces or heat pump systems are eligible. 
    • Your home may be a site-built dwelling or a manufactured home.
    • Duct sealing projects that are completed by a  Performance Tested Comfort Systems (PTCS) Certified Residential Air Distribution Systems Technician will qualify for this rebate.

    Duct sealing performed by a PTCS certified technician will help lower your home heating and cooling costs and improve your indoor air quality.About Duct Sealing

    Your air ducts are one of the most important systems in your home, and if the ducts are poorly sealed they are likely to leak. In homes with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical home, however, about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes and poorly connected ducts.
