What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Barnegat township, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Barnegat township, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. 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?

In Barnegat township, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.

Preparing for a Blower Door Test in Barnegat township, NJ

Preparation for blower door test in Barnegat township, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Barnegat township, NJ.
