What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Brielle, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Brielle, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

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. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Brielle, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test.

Preparing for a Blower Door Test in Brielle, NJ

Before conducting blower door test in Brielle, NJ, we make sure all heating, cooling, and ventilation fans are switched off. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Brielle, NJ energy efficiency codes.
