What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Bedminster, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Bedminster, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Bedminster, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Complying with this benchmark during a blower door test in Bedminster, NJ helps cut energy expenses and meet local building regulations.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Bedminster, NJ

As part of preparing for blower door test in Bedminster, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Bedminster, NJ energy standards.

Blower Door Test for Contractors in Bedminster, NJ

For contractors conducting blower door test in Bedminster, NJ, well-insulated homes generally require only minimal on-site corrections during the test. With materials such as chalk and spray foam, most small leaks or gaps can be sealed immediately on-site.
