Blower Door Test in Brookhaven, PA

How Is A Blower Door Test Conducted?

During blower door test in Brookhaven, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.
