What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Worcester, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

Preparing for a Blower Door Test in Worcester, PA

As part of preparing for blower door test in Worcester, PA, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Worcester, PA.
