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. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Gradyville, 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?

For blower door test in Gradyville, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Properties in Gradyville, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. By meeting this standard in your blower door test in Gradyville, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.

Preparing for a Blower Door Test in Gradyville, PA

As part of preparing for blower door test in Gradyville, PA, we power down the HVAC system along with kitchen and bathroom exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Gradyville, PA.
