What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Bally, PA finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Bally, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in PA.

What Is A Passing Blower Door Test Score?

Properties in Bally, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Reaching this target in your blower door test in Bally, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Bally, PA

To get ready for blower door test in Bally, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. 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 Bally, PA energy code requirements.
