What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Willow Grove, PA helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Willow Grove, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

Preparing for a Blower Door Test in Willow Grove, PA

Preparation for blower door test in Willow Grove, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Willow Grove, PA building codes.
