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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Avalon borough, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

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 door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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.

What Is A Passing Blower Door Test Score?

In Avalon borough, 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 areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Passing this threshold during your blower door test in Avalon borough, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Avalon borough, NJ

For blower door test in Avalon borough, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Avalon borough, NJ.
