Blower Door Test in Freehold borough, NJ

How Is A Blower Door Test Conducted?

In blower door test in Freehold borough, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. 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.
