What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Mount Holly, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Mount Holly, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test.

Preparing for a Blower Door Test in Mount Holly, NJ

To get ready for blower door test in Mount Holly, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area 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 the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Mount Holly, NJ energy code requirements.
