What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. 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 Wood-Ridge, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Wood-Ridge, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

Homes built in Wood-Ridge, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance.

Preparing for a Blower Door Test in Wood-Ridge, NJ

Before conducting blower door test in Wood-Ridge, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to 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. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Wood-Ridge, NJ energy efficiency codes.
