Blower Door Test in Sadsburyville, PA

How Is A Blower Door Test Conducted?

To complete blower door test in Sadsburyville, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.
