What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Hazlet, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Hazlet, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Meeting this level during your blower door test in Hazlet, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Hazlet, NJ

To prepare for blower door test in Hazlet, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Hazlet, NJ.
