Blower Door Test in Hammonton, NJ

How Is A Blower Door Test Conducted?

For blower door test in Hammonton, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.
