Duct Leakage Test in Gibbsboro borough, NJ

Make sure your HVAC system is performing efficiently and meeting local standards with thorough duct leakage test in Gibbsboro borough, NJ. Our certified technicians inspect and measure air leakage in ductwork, enabling homeowners and builders to boost comfort, prevent energy waste, and adhere to state guidelines.

Why Duct Leakage Test is Important In Gibbsboro borough, 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 set in motion important implications for home builders and HVAC contractors who operate in the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under the 2015 regulations. 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 spike your energy costs, wear down your HVAC system, and spread dust and insulation throughout various parts of your home. This makes duct leakage test indispensable no matter the age of your home. Continue reading to understand why duct leakage test is important and the benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Gibbsboro borough, NJ, your technician first seals all supply and return registers except the main return or air handler. A calibrated duct blaster is then mounted to the opening. By depressurizing the duct system, it creates ideal conditions for detecting air leaks.

The duct blaster works together with a precision pressure sensor to measure airflow and pinpoint leaks in the ductwork without disturbing 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 fast, clean, and comfortable for residents throughout the process. Most tests in Gibbsboro borough, NJ are wrapped up in 30 to 60 minutes, with improvements that continue to boost comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to monitor tiny pressure fluctuations that indicate how much air is leaking through the ducts. Understanding this number allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Gibbsboro borough, 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, most households lose 20% to 30% of their heated or cooled air because of duct leaks. Air from outside—whether hot or cold—entering your system forces your HVAC to work harder, increasing utility bills and reducing indoor comfort.

Overworked equipment also causes additional breakdowns and increases repair costs. Proper duct sealing helps enhance the long-term resilience of your HVAC system, lengthening its lifespan and cutting overall maintenance needs.

Duct leaks can also let dust, mold spores, moisture, and other pollutants enter the duct system. This can heighten allergy issues, compromise indoor air quality, and slowly cause expensive structural damage 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 about leaks that occur deep behind walls or ceilings out of sight?

Aerosol sealing technology (AeroSeal) can access interior duct leaks that are difficult to reach manually. To use this method, technicians seal all vents except one access point. The HVAC system is isolated, and a machine is hooked up to the duct system. It pressurizes the ducts and emits a fine aerosol sealant that fills tiny gaps and holes that standard sealing methods can’t access.

This method is extremely effective for sealing small to medium leaks. However, big gaps may still need manual sealing using mastic and tape. Technicians test the ducts for leakage before and after aerosol sealing to determine the reduction level and verify success.

Common Areas of Duct Leakage

The most common spot where air escapes in duct systems is the joints. Ductwork features several metal pieces pressed together using tight fittings and metal bands, though these areas are seldom airtight.

As your HVAC system shifts between hot and cold cycles all year long, the ductwork expands and contracts. 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 Gibbsboro borough, 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 sealed with mastic and approved tape, there is a high chance that leakage is occurring.

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

To achieve a passing duct leakage result, your system needs to be under 4 CFM per 100 square feet when the air handler is installed, or 3 CFM per 100 square feet when it isn’t. For new construction, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Gibbsboro borough, NJ doesn’t pass its duct leakage evaluation, you’re likely paying more for temperature control — and contributing to long-term HVAC strain. Meeting the 3–4 CFM requirement is required not only for code approval but for keeping your home efficient and comfortable.

Your technician will also give expert suggestions on correcting leakage issues, allowing you to pass the test, lower utility expenses, and improve your home’s overall efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins by sealing all the ducts and registers with duct mask tape on both the supply and return side.

After the registers are sealed, we attach our duct tester to the system’s unit or to the main return.

The ducts are then depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
