What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Hammonton town, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

Residential buildings in Hammonton town, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations.

Preparing for a Blower Door Test in Hammonton town, NJ

To get ready for blower door test in Hammonton town, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces 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. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Hammonton town, NJ energy standards.
