What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Gradyville, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Gradyville, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

Construction in Gradyville, PA must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Meeting this benchmark in your blower door test in Gradyville, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

Following the IECC guidelines, PA and many local jurisdictions require blower door test on newly built or renovated residential dwellings. We often work with home builders, contractors, and homeowners requiring blower door test in Gradyville, PA to meet local energy codes and obtain permit approval. A duct leakage test requirement applies if ducts or HVAC units are positioned outside the structure’s thermal envelope. Learn more about energy code compliance.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Gradyville, PA

To ensure accuracy during blower door test in Gradyville, PA, we begin by switching off the HVAC system and all exhaust fans in the home. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Gradyville, PA energy code requirements.
