What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. 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. 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 Gibbsboro borough, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Gibbsboro borough, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Properties in Gibbsboro borough, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally.

Preparing for a Blower Door Test in Gibbsboro borough, NJ

Before starting blower door test in Gibbsboro borough, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Gibbsboro borough, NJ.
