What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. 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 result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Blooming Glen, PA helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Blooming Glen, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

Houses in Blooming Glen, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Preparing for a Blower Door Test in Blooming Glen, PA

To prepare a home for blower door test in Blooming Glen, PA, we shut off the HVAC system and disable all exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering 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 Blooming Glen, PA energy code requirements.
