What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Lindenwold, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Lindenwold, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Lindenwold, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Meeting this benchmark in your blower door test in Lindenwold, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Lindenwold, NJ

To ensure accuracy during blower door test in Lindenwold, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. 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. 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. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Lindenwold, NJ.
