What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Pocopson, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the PA climate.

Preparing for a Blower Door Test in Pocopson, PA

To prepare for blower door test in Pocopson, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to 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 completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Pocopson, PA efficiency standards.
