What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. 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. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Avalon borough, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Avalon borough, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes throughout Avalon borough, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Reaching the target during your blower door test in Avalon borough, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Avalon borough, NJ

We start the process of blower door test in Avalon borough, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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 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. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Avalon borough, NJ efficiency codes.
