What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Surf City, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Surf City, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Surf City, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this standard in your blower door test in Surf City, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Surf City, NJ

Before conducting blower door test in Surf City, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Surf City, NJ energy efficiency codes.
