Why Duct Leakage Test is Important In South Bound Brook, NJ

In many jurisdictions, the 2015 IECC, International Energy Conservation Code governs single-family buildings, while the 2018 IECC applies to multi-family buildings. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test alongside a Blower Door Test must now be completed in newly constructed or remodeled homes to meet the 2015 regulatory standards. Did you know that ducts are among the biggest contributors to air leakage in homes all across Pennsylvania, New Jersey, and Delaware? Leaked air can result in higher utility costs, extra load on your HVAC system, and dust and insulation traveling throughout your home. This makes duct leakage test necessary for homeowners with either older or newly built homes. Read ahead to see why duct leakage test is important and what you gain from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in South Bound Brook, NJ, the technician seals all supply and return registers other than the main return or the air handler. A specially calibrated duct blaster fan is then connected to the opening. This fan depressurizes the ducts to help locate where air is escaping.

The duct blaster uses a precision pressure sensor to monitor airflow and pinpoint leaks throughout the ductwork without interrupting your home environment. A duct leakage test — sometimes called a duct blaster test — reveals where your ducts are losing air so you can determine the most effective sealing solutions.

duct leakage test is swift, clean, and carried out with no disturbance to residents. Most tests in South Bound Brook, NJ finish in 30 to 60 minutes, and the upgrades continue benefiting your home’s comfort and efficiency long after.

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 relies on a nanometer to read slight pressure variations that show the amount of air leaking through the duct system. Understanding this number helps you recognize where issues exist, plan meaningful improvements, and check your home against local energy code requirements in South Bound Brook, NJ.

Cost of Excessive Duct Leakage

If high utility expenses, irregular temperatures, or repeated HVAC troubles sound familiar, duct leakage might be the root cause. According to ENERGY STAR, leaking ducts cause the average home to lose 20%–30% of conditioned air. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also causes components to fail more often, leading to costly repairs. Proper duct sealing helps keep your HVAC system healthy over the long run, prolonging its lifespan and lowering continued maintenance needs.

Duct leaks can also pull dust, mold spores, excess moisture, and various contaminants into the duct system. This can worsen allergies, reduce indoor air quality, and even cause expensive structural damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires newly built homes to install fully sealed duct systems using advanced materials like mastic, foil tape, and quality insulation. But what if the leaks are buried far inside your walls or ceilings?

Aerosol sealing technology (AeroSeal) is used to address openings concealed inside duct systems. 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 pushes a fine aerosol sealant through them, sealing small holes that ordinary sealing methods can’t reach.

This method excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with mastic and tape. Technicians use a duct leakage test before and after aerosol sealing to evaluate how much leakage has been lowered and verify the results.

Common Areas of Duct Leakage

The most frequent source of duct air leakage is the joints. Ductwork uses many metal pieces pressed together with tight fittings and metal bands, but these joining points are rarely airtight.

As your HVAC system changes between heating and cooling during the year, the ducts naturally expand and shrink. Over time, this movement results in loose joints that create gaps and leaks — making a duct leakage test necessary for new and older homes in South Bound Brook, NJ.

Many energy auditors verify duct leakage by feeling around the ducts and using a small tool to assess the opening size at the joints. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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

To achieve a passing duct leakage result, your system should stay under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it. For new construction, an occupancy certificate cannot be issued unless the home passes a duct leakage test.

If your home in South Bound Brook, NJ fails duct leakage test, you are probably spending unnecessarily on heating and cooling — and placing ongoing stress on your HVAC equipment. Meeting the 3–4 CFM requirement is indispensable not only for compliance purposes but for ensuring strong comfort and energy savings.

Your technician will also provide expert recommendations on how to address leakage issues so you can achieve a passing score, lower your utility bills, and improve your home’s overall 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 until they reach 25 Pascals. With them depressurized, the nanometer measures the amount of leakage.
