What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Upper, 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?

When blower door test in Upper, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer precisely gauges the pressure applied by the fan in relation 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.

Preparing for a Blower Door Test in Upper, NJ

For blower door test in Upper, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. 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. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Upper, NJ.
