How Is A Blower Door Test Conducted?

Before blower door test in Seaside Heights borough, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.
