What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Glen Rock, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 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.

In Glen Rock, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction.

Preparing for a Blower Door Test in Glen Rock, NJ

To ensure accuracy during blower door test in Glen Rock, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues 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 Glen Rock, NJ energy efficiency codes.
