What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Pennsauken township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Preparing for a Blower Door Test in Pennsauken township, NJ

To properly prepare for blower door test in Pennsauken township, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Pennsauken township, NJ.
