What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Franklin township (Gloucester), NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

Preparing for a Blower Door Test in Franklin township (Gloucester), NJ

To ensure accuracy during blower door test in Franklin township (Gloucester), NJ, we begin by switching off the HVAC system and all exhaust fans in the home. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Franklin township (Gloucester), NJ efficiency codes.
