What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Robbinsville, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Robbinsville, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. 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 Robbinsville, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Achieving this standard in your blower door test in Robbinsville, NJ lowers utility bills and guarantees adherence to local code requirements.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Robbinsville, NJ

For blower door test in Robbinsville, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Robbinsville, NJ.
