What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Chadds Ford, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Chadds Ford, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in Chadds Ford, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. By meeting this standard in your blower door test in Chadds Ford, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Chadds Ford, PA

To ensure accuracy during blower door test in Chadds Ford, PA, we begin by switching off the HVAC system and all exhaust fans in the home. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Chadds Ford, PA.
