What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Hazlet, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Hazlet, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. 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.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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 Hazlet, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Meeting this requirement during your blower door test in Hazlet, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Hazlet, NJ

As part of preparing for blower door test in Hazlet, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. 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, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Hazlet, NJ building codes.
