What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Rutherford, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Rutherford, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Rutherford, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Meeting this requirement during your blower door test in Rutherford, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Rutherford, NJ

To prepare a home for blower door test in Rutherford, NJ, we shut off the HVAC system and disable all 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 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Rutherford, NJ building codes.
