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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Plainsboro, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Plainsboro, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Plainsboro, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions.

Preparing for a Blower Door Test in Plainsboro, NJ

Before conducting blower door test in Plainsboro, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Plainsboro, NJ efficiency codes.
