What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Maywood, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Maywood, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Maywood, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Meeting this level during your blower door test in Maywood, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Maywood, NJ

To ensure accuracy during blower door test in Maywood, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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 highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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 leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Maywood, NJ.
