Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Raritan borough, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

Homes in Raritan borough, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally.

Preparing for a Blower Door Test in Raritan borough, NJ

Before starting blower door test in Raritan borough, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Raritan borough, NJ building codes.
