What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Sea Girt, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Sea Girt, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. 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 NJ climate.

Homes throughout Sea Girt, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators.

Preparing for a Blower Door Test in Sea Girt, NJ

To get ready for blower door test in Sea Girt, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Sea Girt, NJ.
