What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Northvale, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Northvale, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Northvale, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Northvale, 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 Northvale, NJ

As part of preparing for blower door test in Northvale, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. 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. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Northvale, NJ energy efficiency codes.
