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. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. 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 Eagleville, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Eagleville, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

Properties in Eagleville, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing.

Preparing for a Blower Door Test in Eagleville, PA

Preparation for blower door test in Eagleville, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Eagleville, PA energy standards.
