What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Collingswood, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

In Collingswood, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency.

Preparing for a Blower Door Test in Collingswood, NJ

For blower door test in Collingswood, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Collingswood, NJ energy standards.
