What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Devon, PA identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Devon, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home 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 Devon, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this requirement during your blower door test in Devon, PA helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Devon, PA

To prepare a home for blower door test in Devon, PA, we shut off the HVAC system and disable all exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Devon, PA energy efficiency codes.
