Blower Door Test in Logan township, NJ

How Is A Blower Door Test Conducted?

For blower door test in Logan township, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. 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 expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.
