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. 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. 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 Wayne, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Wayne, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

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. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Wayne, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Passing this requirement during a blower door test in Wayne, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Wayne, NJ

To get ready for blower door test in Wayne, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Wayne, NJ efficiency standards.
