What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in North Arlington, 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?

To perform blower door test in North Arlington, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Residential buildings in North Arlington, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Passing this threshold during your blower door test in North Arlington, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in North Arlington, NJ

Getting ready for blower door test in North Arlington, NJ involves turning off all heating, cooling, and exhaust ventilation systems. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside 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. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. 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 North Arlington, NJ.
