Blower Door Test in Barnegat, NJ

Make sure your home meets airtightness and efficiency goals with certified blower door test in Barnegat, NJ. Our certified professionals work with homeowners, builders, and contractors to uncover hidden air leaks and guarantee compliance with NJ energy codes.

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. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Barnegat, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Barnegat, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Barnegat, 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. When your blower door test in Barnegat, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Why Do I Need A Blower Door Test?

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Barnegat, NJ

Before conducting blower door test in Barnegat, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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 all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Barnegat, NJ.
