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. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Hillside, 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?

When conducting blower door test in Hillside, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Hillside, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Reaching the target during your blower door test in Hillside, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Hillside, NJ

To get ready for blower door test in Hillside, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements 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 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 bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Hillside, NJ energy efficiency codes.
