Blower Door Test in Little Egg Harbor township, NJ

How Is A Blower Door Test Conducted?

While performing blower door test in Little Egg Harbor township, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.
