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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Morton, PA helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Morton, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.

What Is A Passing Blower Door Test Score?

Properties in Morton, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Reaching the target during your blower door test in Morton, PA guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Morton, PA

To get ready for blower door test in Morton, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Morton, PA.
