Blower Door Test in Pennsville, NJ

Protect your energy investment and verify airtightness with advanced blower door test in Pennsville, NJ. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with NJ building energy standards.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Pennsville, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Pennsville, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout 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.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Homes built in Pennsville, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Passing this requirement during a blower door test in Pennsville, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Pennsville, NJ

We begin blower door test in Pennsville, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Pennsville, NJ.

Blower Door Test for Contractors in Pennsville, NJ

For contractors arranging blower door test in Pennsville, NJ, most homes with professional insulation can handle small air leakage issues during the test itself.
