What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Washington township, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Washington township, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Washington township, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards.

Preparing for a Blower Door Test in Washington township, NJ

When preparing for blower door test in Washington township, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Washington township, NJ energy code requirements.
