What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Bensalem, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

Residential buildings in Bensalem, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing.

Preparing for a Blower Door Test in Bensalem, PA

Preparation for blower door test in Bensalem, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Bensalem, PA energy standards.
