What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Royersford, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Royersford, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Royersford, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities.

Preparing for a Blower Door Test in Royersford, PA

To properly prepare for blower door test in Royersford, PA, the HVAC system and all bathroom and kitchen fans are turned off. 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 ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Royersford, PA efficiency codes.
