Blower Door Test in Somers Point, NJ

How Is A Blower Door Test Conducted?

During blower door test in Somers Point, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. 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.
