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. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. 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 Woodbury, 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?

To execute blower door test in Woodbury, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 Woodbury, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards.

Preparing for a Blower Door Test in Woodbury, NJ

To ensure accuracy during blower door test in Woodbury, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. 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 ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Woodbury, NJ energy code requirements.
