What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Gwynedd Valley, PA detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Gwynedd Valley, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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?

Construction in Gwynedd Valley, 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. Reaching this target in your blower door test in Gwynedd Valley, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Gwynedd Valley, PA

Before starting blower door test in Gwynedd Valley, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Gwynedd Valley, PA energy standards.
