What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Gibbsboro, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Properties in Gibbsboro, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Achieving this goal during your blower door test in Gibbsboro, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

NJ, along with many city governments, enforces the IECC, which requires blower door test for residential projects after construction or renovation.

Preparing for a Blower Door Test in Gibbsboro, NJ

Getting ready for blower door test in Gibbsboro, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Gibbsboro, NJ.

Blower Door Test for Contractors in Gibbsboro, NJ

For contractors arranging blower door test in Gibbsboro, NJ, most homes with professional insulation can handle small air leakage issues during the test itself.
