What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Nutley, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Nutley, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Houses in Nutley, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Complying with this benchmark during a blower door test in Nutley, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Nutley, NJ

To ensure accuracy during blower door test in Nutley, 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. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. 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 Nutley, NJ.
