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. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Woodbridge, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Woodbridge, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

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. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Woodbridge, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Passing this threshold during your blower door test in Woodbridge, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Woodbridge, NJ

To get ready for blower door test in Woodbridge, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom 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 the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Woodbridge, NJ energy code requirements.
