What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Zieglerville, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

Preparing for a Blower Door Test in Zieglerville, PA

To ensure accuracy during blower door test in Zieglerville, PA, we begin by switching off the HVAC system and all exhaust fans in the home. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Zieglerville, PA building codes.
