What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Neptune, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Neptune, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel 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 removes air, outside air naturally flows inside through leaks, joints, and other gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Neptune, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Passing this threshold during your blower door test in Neptune, NJ ensures both energy savings and full compliance with local regulations.

Why Do I Need A Blower Door Test?

Following the IECC guidelines, NJ and many local jurisdictions require blower door test on newly built or renovated residential dwellings. Our team regularly helps home builders, contractors, and homeowners seeking blower door test in Neptune, NJ to satisfy energy code standards and close final inspections.

Preparing for a Blower Door Test in Neptune, NJ

To get ready for blower door test in Neptune, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Neptune, NJ.
