What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. 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 Montvale, 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 Montvale, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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 starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Montvale, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Complying with this benchmark during a blower door test in Montvale, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Montvale, NJ

Preparation for blower door test in Montvale, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Montvale, NJ.
