Blower Door Test in Neptune, NJ

How Is A Blower Door Test Conducted?

For blower door test in Neptune, 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. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.
