What Is A Blower Door Test?

An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in East Greenwich township, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in East Greenwich township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. 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.

Preparing for a Blower Door Test in East Greenwich township, NJ

Before starting blower door test in East Greenwich township, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in East Greenwich township, NJ.
