What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Brooksi, DE identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Brooksi, DE, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the DE climate.

Homes in Brooksi, DE are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version 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 Brooksi, DE

Preparation for blower door test in Brooksi, DE begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Brooksi, DE energy standards.
