Blower Door Test in Wood-Ridge, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in Wood-Ridge, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. 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.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?
