What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Penns Park, PA identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Penns Park, PA, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes in Penns Park, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Reaching the target during your blower door test in Penns Park, PA guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Penns Park, PA

Before starting blower door test in Penns Park, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Penns Park, PA.
