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. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Hamilton township, 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?

During blower door test in Hamilton township, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural 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?

Homes in Hamilton township, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching the target during your blower door test in Hamilton township, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Hamilton township, NJ

When preparing for blower door test in Hamilton 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Hamilton township, NJ.
