Make sure your home meets airtightness and efficiency goals with certified blower door test in Ridgefield, NJ. Our professional technicians help homeowners, builders, and contractors identify air leaks, improve home comfort, and satisfy NJ energy code regulations.

What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Ridgefield, 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 conducting blower door test in Ridgefield, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Ridgefield, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving compliance in your blower door test in Ridgefield, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Ridgefield, NJ

To get ready for blower door test in Ridgefield, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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 the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Ridgefield, NJ efficiency standards.
