What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Mont Clare, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Mont Clare, PA, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Complying with this benchmark during a blower door test in Mont Clare, PA helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Mont Clare, PA

Preparation for blower door test in Mont Clare, PA begins with switching off the HVAC system, as well as any bathroom and kitchen 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. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Mont Clare, PA energy code requirements.
