What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Lopatcong, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural 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 Lopatcong, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this requirement during a blower door test in Lopatcong, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Lopatcong, NJ

Preparation for blower door test in Lopatcong, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Lopatcong, NJ energy code requirements.
