Blower Door Test in Somerdale, NJ

How Is A Blower Door Test Conducted?

During blower door test in Somerdale, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.
