What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Hammonton town, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Hammonton town, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

Preparing for a Blower Door Test in Hammonton town, NJ

Before conducting blower door test in Hammonton town, NJ, we make sure all heating, cooling, and ventilation fans are switched off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. 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 Hammonton town, NJ.
