What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Oradell borough, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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 the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Houses in Oradell borough, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. 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 Oradell borough, NJ

To ensure accuracy during blower door test in Oradell borough, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Oradell borough, NJ energy standards.
