What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Bound Brook, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Bound Brook, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Bound Brook, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Complying with this benchmark during a blower door test in Bound Brook, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Bound Brook, NJ

We begin blower door test in Bound Brook, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Bound Brook, NJ efficiency codes.
