Ensure your home is sealed properly and energy-efficient with quality blower door test in Saddle River, NJ. Our trained team assists homeowners, builders, and contractors by detecting hidden air leaks, boosting comfort, and meeting NJ energy regulations.

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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Saddle River, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Saddle River, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Homes throughout Saddle River, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. 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 Saddle River, NJ supports energy efficiency and verifies that your home meets local codes.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Saddle River, NJ

To properly prepare for blower door test in Saddle River, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. 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. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Saddle River, NJ.
