What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Feasterville Trevose, PA is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

Preparing for a Blower Door Test in Feasterville Trevose, PA

A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Feasterville Trevose, PA.
