Blower Door Test in Fanwood, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Fanwood, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?
