What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Millstone township, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Millstone township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching the target during your blower door test in Millstone township, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Millstone township, NJ

To get ready for blower door test in Millstone township, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside 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. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Millstone township, NJ.
