What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. 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. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Coopersburg, PA helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Coopersburg, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

Preparing for a Blower Door Test in Coopersburg, PA

When preparing for blower door test in Coopersburg, PA, we first switch off the home’s heating, cooling, and exhaust systems. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Coopersburg, PA energy code requirements.
