Duct Leakage Test in Glen Ridge, NJ

Keep your HVAC system energy-efficient and up to code with accurate duct leakage test in Glen Ridge, NJ. Our certified technicians evaluate and measure air leaks in duct systems, helping homeowners and builders enhance comfort, decrease energy loss, and comply with state rules.

Why Duct Leakage Test is Important In Glen Ridge, NJ

States and municipalities have standardized around the 2015 IECC, International Energy Conservation Code for single-family builds and the 2018 International Energy Conservation Code for multi-family builds. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test along with the required Blower Door Test must now be conducted on any newly built or remodeled home as per the 2015 regulations. Did you know that ducts are a leading factor in home air leakage across Pennsylvania, New Jersey, and Delaware? Leaked air can raise utility expenses, overburden your HVAC system, and push insulation material and dust through every area of your home. This makes duct leakage test essential for both new and older homes. Continue reading to understand why duct leakage test matters and how it can benefit you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To kick off a duct leakage test in Glen Ridge, NJ, your technician will block all supply and return registers while keeping the main return or air handler accessible. A duct blaster fan, carefully calibrated for accuracy, is then attached to the duct opening. It depressurizes the ductwork, allowing leaks to become more noticeable.

The duct blaster uses its precision pressure sensor partner to measure airflow and uncover duct leaks without causing any home disruption. A duct leakage test — also called a duct blaster test — locates the points where duct air escapes, helping you implement the right sealing solution.

duct leakage test is straightforward, clean, and designed to be non-intrusive for residents. Most tests in Glen Ridge, NJ take just 30 to 60 minutes, and the resulting improvements can enhance your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is expressed in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned area. Your technician uses a nanometer to capture subtle pressure changes, allowing accurate measurement of duct air leakage. Understanding this number helps you pinpoint leakage points, think through potential improvements, and verify your home’s adherence to local energy code requirements in Glen Ridge, NJ.

Cost of Excessive Duct Leakage

If you are experiencing high utility bills, uneven temperatures, or frequent HVAC repairs, duct leakage may be the cause. According to ENERGY STAR, many homes lose as much as 20% to 30% of conditioned air through duct leaks. Outside air that’s too hot or too cold entering your system strains your HVAC, resulting in higher energy consumption and less comfort.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also pull dust, mold spores, excess moisture, and various contaminants into the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC ensures that new homes are built with duct systems sealed entirely using efficient materials such as mastic, foil tape, and insulation. But what if those leaks are tucked away behind walls or ceilings?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method is ideal for small to medium leaks. However, any large openings will still need manual sealing with mastic and tape. Technicians use before-and-after duct leakage tests to measure improvement and make sure the aerosol sealing process was successful.

Common Areas of Duct Leakage

The most frequent point of air leakage in ductwork is the joints. Multiple metal parts are pressed together using tight fittings and metal bands, although these junctions are seldom airtight.

As your HVAC system changes between heating and cooling during the year, the ducts naturally expand and shrink. Over time, this movement leads the joints to loosen, resulting in gaps and leaks — making a duct leakage test important for new and older homes in Glen Ridge, NJ.

Many energy auditors detect leaks by checking the duct surfaces by hand and using a small tool to measure joint gap width. If your duct system isn’t sealed with mastic and approved tape, there’s a good chance that leaks are occurring.

What Is an Acceptable Amount of Duct Leakage per Energy Code?

To achieve a passing duct leakage result, your system has to measure below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler. For new construction, homes are required to pass a duct leakage test before an occupancy certificate can be issued.

If your home in Glen Ridge, NJ does not meet the duct leakage requirement, you’re likely paying elevated heating and cooling costs — and overburdening your HVAC system. Meeting the 3–4 CFM requirement is significant not only for meeting local code but also for maintaining optimal comfort and efficiency in your home.

Your technician will also offer specialized recommendations to repair leakage issues so you can meet passing requirements, reduce utility bills, and improve your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with the technician sealing all ducts and registers using duct mask tape across the supply and return sides.

After the registers are sealed, we attach the duct tester to either the unit itself or a main return.

The ducts are then depressurized to 25 Pascals. With the ducts at this pressure, we can use the nanometer to measure the duct leakage.
