What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Clinton township, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Clinton township, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. 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.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Preparing for a Blower Door Test in Clinton township, NJ

We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Clinton township, NJ.
