What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Ridley Park, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

Preparing for a Blower Door Test in Ridley Park, PA

Before conducting blower door test in Ridley Park, PA, we make sure all heating, cooling, and ventilation fans are switched off. 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 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and 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. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Ridley Park, PA energy code requirements.
