What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Pike Creek, DE, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. 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 Pike Creek, DE, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance.

Preparing for a Blower Door Test in Pike Creek, DE

To ensure accuracy during blower door test in Pike Creek, DE, 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 airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Pike Creek, DE.
