What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing 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 East Brunswick, 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?

During blower door test in East Brunswick, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

Preparing for a Blower Door Test in East Brunswick, NJ

To ensure accuracy during blower door test in East Brunswick, NJ, 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. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets East Brunswick, NJ efficiency codes.
