What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Perkasie, 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?

While performing blower door test in Perkasie, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

In Perkasie, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. 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 requirement during your blower door test in Perkasie, PA helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Perkasie, PA

Before starting blower door test in Perkasie, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Perkasie, PA.
