What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Ship Bottom, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Ship Bottom, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Meeting this requirement during your blower door test in Ship Bottom, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Ship Bottom, NJ

To prepare for blower door test in Ship Bottom, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen 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 everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Ship Bottom, NJ building codes.
