What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Oaklyn, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Oaklyn, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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 indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

Properties in Oaklyn, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally.

Preparing for a Blower Door Test in Oaklyn, NJ

We begin blower door test in Oaklyn, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Oaklyn, NJ.
