What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Bloomfield, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Bloomfield, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Properties in Bloomfield, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Reaching this target in your blower door test in Bloomfield, NJ helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Bloomfield, NJ

To prepare a home for blower door test in Bloomfield, NJ, we shut off the HVAC system and disable all exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Bloomfield, NJ efficiency standards.
