    Ask us about energy-saving blower door tests and duct leakage tests for compliance with Washington State’s required Air Leakage Testing (R402.4.1.2). Lifetime Heating and Air Conditioning provides timely air leakage and duct leakage inspections for new and existing homes.

    Additionally, we offer home weatherization services including air sealing, duct sealing, bath fans, and attic storage platforms. We work with Western Washington builders and homeowners from Olympia to Bellingham (including Tacoma, Seattle, Bellevue, Kirkland, Everett and surrounding areas).


    Don’t miss your closing date due to a failed blower door test! We offer pre-test consultation to help you address and identify the areas that can lead to test failure. Correcting these items before sheet rock can help to avoid costly repairs once the house is in the finished stage and ready for final inspection.

    Duct Testing

    In addition to blower door tests, we offer high-quality inspections for ductwork for homes with forced air or air conditioning. For duct tests, our technicians seal off and depressurize the ventilation system. Then with specialized equipment, they determine how much air pressure is escaping. These duct leakage tests ensure that your system is properly sealed and energy efficient.

    Prices range from $250 to $500 depending on size of the house. We will review your blueprints, measure the house for accurate square footage and volume and provide a complete test certificate including R Values, fuel source and efficiency rating for Heating, Cooling and Domestic Hot Water and of course the Building Air Leakage test results. We will post the required 2012 WSEC Residential Energy Compliance Certificate on or near the electrical panel as required by code.
