Blower Door Test in Hamilton township (Atlantic), NJ

How Is A Blower Door Test Conducted?

When conducting blower door test in Hamilton township (Atlantic), NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. 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. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.
