Blower Door Test in Island Heights borough, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Island Heights borough, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Island Heights borough, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. When your blower door test in Island Heights borough, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.
