Blower Door Test in Burlington township, NJ

How Is A Blower Door Test Conducted?

While performing blower door test in Burlington township, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.
