What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Tavistock, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Tavistock, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Tavistock, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. When your blower door test in Tavistock, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Tavistock, NJ

To prepare for blower door test in Tavistock, 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. 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 depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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 sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Tavistock, NJ.
