What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. 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 Edgemont, 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 execute blower door test in Edgemont, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

Homes built in Edgemont, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. When your blower door test in Edgemont, PA meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Edgemont, PA

To properly prepare for blower door test in Edgemont, PA, the HVAC system and all bathroom and kitchen fans are turned off. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Edgemont, PA.
