What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. 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 Gloucester, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Gloucester, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Homes built in Gloucester, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this benchmark in your blower door test in Gloucester, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Gloucester, NJ

Getting ready for blower door test in Gloucester, 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 the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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 completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Gloucester, NJ efficiency standards.
