Blower Door Test in East Rutherford, NJ

How Is A Blower Door Test Conducted?

To execute blower door test in East Rutherford, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?
