What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Weymouth, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Weymouth, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. 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 Weymouth, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Weymouth, NJ

We begin blower door test in Weymouth, NJ by switching off the HVAC system and shutting down all exhaust fans throughout 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 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 from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Weymouth, NJ.
