What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Manchester township, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Manchester township, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

Preparing for a Blower Door Test in Manchester township, NJ

As part of preparing for blower door test in Manchester township, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Manchester township, NJ.
