What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Perkiomenville, PA assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Perkiomenville, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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 removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.

What Is A Passing Blower Door Test Score?

In Perkiomenville, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Achieving this goal during your blower door test in Perkiomenville, PA promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Perkiomenville, PA

To prepare for blower door test in Perkiomenville, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Perkiomenville, PA energy code requirements.
