Blower Door Test in Little Ferry, NJ

How Is A Blower Door Test Conducted?

To conduct blower door test in Little Ferry, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.
