What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Haddon, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Haddon, 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. 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 the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Construction in Haddon, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. When your blower door test in Haddon, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Haddon, NJ

We begin blower door test in Haddon, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining 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 depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Haddon, NJ.
