What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Eagleswood township, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Eagleswood township, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Homes built in Eagleswood township, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect.

Preparing for a Blower Door Test in Eagleswood township, NJ

We start the process of blower door test in Eagleswood township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. 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. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Eagleswood township, NJ energy standards.
