What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Mullica 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 sturdy fabric panel are installed in one central exterior door to prepare for testing. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site.
