What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Quakertown, PA finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Quakertown, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. 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 depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under PA weather.

Preparing for a Blower Door Test in Quakertown, PA

To ensure accuracy during blower door test in Quakertown, PA, we begin by switching off the HVAC system and all exhaust fans in the home. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Quakertown, PA efficiency codes.
