What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. 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 often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Bridgeville, DE 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?

When blower door test in Bridgeville, DE is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the DE climate.

What Is A Passing Blower Door Test Score?

In Bridgeville, DE, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally.

Preparing for a Blower Door Test in Bridgeville, DE

To ensure accuracy during blower door test in Bridgeville, DE, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Bridgeville, DE.
