A blower door test in Audubon, PA helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Audubon, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

In Audubon, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Meeting this requirement during your blower door test in Audubon, PA helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Audubon, PA

To prepare for blower door test in Audubon, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen 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. 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Audubon, PA.
