What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. 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 Morton, PA helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Morton, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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 Morton, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Reaching the target during your blower door test in Morton, PA guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Morton, PA

Getting ready for blower door test in Morton, PA involves turning off all heating, cooling, and exhaust ventilation systems. 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. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Morton, PA energy code requirements.
