What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Rising Sun-Lebanon, DE assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Rising Sun-Lebanon, DE, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in DE weather.

What Is A Passing Blower Door Test Score?

In Rising Sun-Lebanon, DE, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this benchmark in your blower door test in Rising Sun-Lebanon, DE reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Rising Sun-Lebanon, DE

To ensure accuracy during blower door test in Rising Sun-Lebanon, DE, we begin by switching off the HVAC system and all exhaust fans in the home. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. 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 Rising Sun-Lebanon, DE.
