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. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Saint Peters, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Saint Peters, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this requirement during your blower door test in Saint Peters, PA helps reduce energy costs while keeping your home compliant with local building codes.

Homeowners who choose blower door test in Saint Peters, PA can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement.

Preparing for a Blower Door Test in Saint Peters, PA

To prepare a home for blower door test in Saint Peters, PA, we shut off the HVAC system and disable all exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. 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 completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Saint Peters, PA efficiency standards.
