Blower Door Test in South Toms River borough, NJ

How Is A Blower Door Test Conducted?

Before blower door test in South Toms River borough, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.
