What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Bally, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Bally, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in Bally, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations.

Preparing for a Blower Door Test in Bally, PA

We begin blower door test in Bally, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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 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. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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. 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 Bally, PA.
