What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Bayville, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. 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?

In Bayville, 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 Bayville, NJ

Before conducting blower door test in Bayville, NJ, we make sure all heating, cooling, and ventilation fans are switched off. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces 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 depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Bayville, NJ.
