Energy Audits, Insulation & Testing in Southern Maine & the Seacoast NH
Efficient Home Services, LLC is based in Berwick, Maine. We provide home energy audits, insulation and air sealing, and blower door and duct leakage testing for homeowners and builders, including energy code air leakage testing for new construction. We serve York County, Maine, including Berwick, Kittery, York, Wells and Sanford, and the New Hampshire seacoast, including Portsmouth, Dover and Rochester.
Blower Door Testing
Every home energy audit we do starts with a blower door test. A calibrated fan in an exterior doorway depressurizes the house so we can measure how leaky it is and find where the drafts are coming from. Builders use the same test to show a new home meets the energy code air leakage requirement. Learn more about blower door and duct leakage testing, or see what's included in a home energy audit.
