What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. 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 Pemberton township, 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?

For blower door test in Pemberton township, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Houses in Pemberton township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving this goal during your blower door test in Pemberton township, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Pemberton township, NJ

Before starting blower door test in Pemberton township, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Pemberton township, NJ building codes.
