What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Aberdeen, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

Preparing for a Blower Door Test in Aberdeen, NJ

Preparation for blower door test in Aberdeen, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Aberdeen, NJ.
