Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Crum Lynne, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

Preparing for a Blower Door Test in Crum Lynne, PA

Before starting blower door test in Crum Lynne, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Crum Lynne, PA.
