Blower Door Testing

Blower Door Testing measures a home's air tightness by using a powerful fan installed in an exterior door. The fan presses air in or out, creating a pressure difference that reveals how much air leaks through gaps, cracks, or openings. By monitoring the pressure and airflow, technicians determine the home's overall airtightness and identify areas needing sealing. This test helps improve energy efficiency, comfort, and indoor air quality by reducing unnecessary heat loss or gain. It’s a standard method for assessing building envelope performance, ensuring a well-sealed, energy-efficient home.
