Blower Door Test in Asbury Park, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Asbury Park, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. 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?
