Blower Door Test in Asbury Park, NJ

How Is A Blower Door Test Conducted?

In preparation for blower door test in Asbury Park, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.
