What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Barto, PA helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Barto, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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 Barto, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this goal during your blower door test in Barto, PA promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Barto, PA

To prepare a home for blower door test in Barto, 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Barto, PA efficiency standards.
