What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Egg Harbor, 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?

To carry out blower door test in Egg Harbor, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Homes in Egg Harbor, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Meeting this benchmark in your blower door test in Egg Harbor, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Egg Harbor, NJ

Before starting blower door test in Egg Harbor, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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 the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Egg Harbor, NJ energy efficiency codes.
