What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Haddon Heights, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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 the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively.
