What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Wyncote, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under PA conditions.

What Is A Passing Blower Door Test Score?

Houses in Wyncote, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this benchmark in your blower door test in Wyncote, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Wyncote, PA

To prepare a home for blower door test in Wyncote, PA, we shut off the HVAC system and disable all exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. 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’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. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Wyncote, PA.
