Duct Leakage Test in Little Egg Harbor township, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Little Egg Harbor township, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Little Egg Harbor township, NJ

States and municipalities are using the 2015 IECC, International Energy Conservation Code for single-family construction and the 2018 International Energy Conservation Code for multi-family construction. The change will carry significant implications for home builders and HVAC contractors serving communities in the state. A Duct Leakage Test and a mandatory Blower Door Test are now required for all new construction or remodeled homes under the 2015 regulatory standards. Did you know that ducts are one of the primary sources of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can lead to rising energy bills, added strain on your HVAC system, and unwanted insulation and dust spreading through your home. This makes duct leakage test necessary for homes of any age. Keep reading to discover why duct leakage test is so important and the advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To commence a duct leakage test in Little Egg Harbor township, NJ, your technician will seal every supply and return register except the primary return or air handler. A duct blaster — a precision-calibrated fan — is then fitted to the duct opening. By depressurizing the system, it makes all air leaks much easier to detect.

The duct blaster pairs with a precision pressure sensor to measure airflow and identify leak locations in the ducts without disrupting your home. A duct leakage test — sometimes known as a duct blaster test — shows exactly where your ducts are leaking air so you can apply the right sealing fixes.

duct leakage test is swift, clean, and carried out with no disturbance to residents. Most tests in Little Egg Harbor township, NJ take only 30 to 60 minutes, yet the comfort and efficiency gains can last for years.

How to Measure Duct Leakage

Duct leakage is evaluated in cubic feet per minute (CFM) per 100 square feet of conditioned space inside the home. 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 spot leakage issues, evaluate corrective measures, and determine if your home is meeting local energy code requirements in Little Egg Harbor township, NJ.

Cost of Excessive Duct Leakage

If you’re facing higher energy bills, uneven heating or cooling, or recurring HVAC repairs, duct leakage could be to blame. According to ENERGY STAR, duct leakage causes homeowners to lose 20%–30% of their conditioned air on average. Air entering from outside—whether warm or cold—makes your HVAC operate harder, causing energy costs to climb and comfort to decrease.

Overworked equipment also causes components to fail more often, leading to costly repairs. Proper duct sealing helps ensure the long-term stability of your HVAC system, extending its lifespan and reducing future maintenance work.

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter the duct system. This can escalate allergies, lower the overall air quality indoors, and lead to costly damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates that new homes include fully sealed duct systems built with energy-efficient materials like mastic, foil tape, and proper insulation. But what if leaks are concealed deep inside the structure of your walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To set up this method, all vents are sealed off except for a single access point. The HVAC system is isolated, and a machine is fitted to the duct system. It pressurizes the ducts and releases a fine sealant mist that finds and fills small holes that traditional sealing methods cannot access.

This method is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians complete before-and-after duct leakage tests to measure leakage reduction and ensure the aerosol sealing was effective.

Common Areas of Duct Leakage

The most usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system delivers heat and cooling across different seasons, the ducts constantly expand and contract. Over time, this movement gradually loosens the joints, creating leaks and gaps — highlighting the importance of duct leakage test in both new and older homes in Little Egg Harbor township, NJ.

Many energy auditors check for leaks by feeling along the ductwork and using a small tool to gauge the size of gaps between joints. If your duct system has not been properly sealed with mastic and approved tape, it’s very likely that leakage exists.

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

To achieve a passing duct leakage result, your system has to be under 4 CFM per 100 square feet when the air handler is in place, or 3 CFM per 100 square feet without it installed. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Little Egg Harbor township, NJ fails a duct leakage test, you are probably spending more than you should on heating and cooling — while also putting long-term stress on your HVAC system. Meeting the 3–4 CFM requirement is key not only for staying code-compliant but for maintaining energy efficiency and consistent comfort 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 sealing each duct and register using duct mask tape on the supply and return sides.

After the registers are sealed, we mount the duct tester onto the unit or onto a main return.

The ducts are then depressurized to exactly 25 Pascals. Once this is achieved, the nanometer is used to read the duct leakage.
