A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Center Valley, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

Homes built in Center Valley, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Passing this threshold during your blower door test in Center Valley, PA ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Center Valley, PA

Preparation for blower door test in Center Valley, 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. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. 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 sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Center Valley, PA.
