A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Carteret, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Carteret, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Achieving this goal during your blower door test in Carteret, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Carteret, NJ

We start the process of blower door test in Carteret, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points 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 Carteret, NJ energy efficiency codes.
