What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Port Republic city, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Port Republic city, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in Port Republic city, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Meeting this benchmark in your blower door test in Port Republic city, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Port Republic city, NJ

Before starting blower door test in Port Republic city, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Port Republic city, NJ.
