What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Butler, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. 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?

In Butler, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Complying with this benchmark during a blower door test in Butler, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Butler, NJ

Preparation for blower door test in Butler, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. 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 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 Butler, NJ.
