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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. 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 Absecon, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Absecon, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

In Absecon, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency.

Preparing for a Blower Door Test in Absecon, NJ

To get ready for blower door test in Absecon, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Absecon, NJ energy standards.
