What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Oaks, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. 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?

In Oaks, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test.

Preparing for a Blower Door Test in Oaks, PA

Before conducting blower door test in Oaks, PA, we make sure all heating, cooling, and ventilation fans are switched off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Oaks, PA energy code requirements.
