Duct Leakage Test in Maurice River, NJ

Make sure your HVAC system is performing efficiently and meeting local standards with thorough duct leakage test in Maurice River, NJ. Our certified technicians locate and assess air leaks in ductwork to help homeowners and builders improve comfort, reduce energy consumption, and comply with state regulations.

Why Duct Leakage Test is Important In Maurice River, NJ

States and municipalities have put in place the 2015 IECC, International Energy Conservation Code for single-family projects and the 2018 International Energy Conservation Code for multi-family projects. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test as well as the required Blower Door Test must now be performed on new or remodeled homes following the 2015 regulations. Did you know that duct systems contribute heavily to air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test critical for both modern and older homes. Continue reading to explore why duct leakage test is important and how you benefit from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin performing a duct leakage test in Maurice River, NJ, your technician closes off all supply and return registers except the main return or air handler system. 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 uses a precision pressure sensor to monitor airflow and pinpoint leaks throughout the ductwork without interrupting your home environment. 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 efficient, clean, and performed without bothering residents. Most tests in Maurice River, NJ require only 30 to 60 minutes, yet the upgrades can improve your home’s comfort and efficiency well into the future.

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 capture subtle pressure changes, allowing accurate measurement of duct air leakage. Understanding this number helps you identify problem areas, evaluate potential improvements, and determine whether your home meets local energy code requirements in Maurice River, NJ.

Cost of Excessive Duct Leakage

If you’re dealing with rising utility bills, inconsistent room temperatures, or repeated HVAC issues, duct leakage could be the reason. According to ENERGY STAR, typical duct systems lose 20% to 30% of conditioned air through leaks. If hot or cold air from outdoors enters your system, your HVAC works harder than necessary, causing energy costs to rise and comfort to fall.

Overworked equipment also creates more wear, leading to breakdowns and costly fixes. 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 cause dust, mold spores, and excess moisture — along with other contaminants — to infiltrate the duct system. This can intensify allergy symptoms, harm indoor air quality, and cause long-term structural damage behind walls or ceilings.

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 leaks are concealed deep inside the structure of your walls or ceilings?

Aerosol sealing technology (AeroSeal) helps seal hard-to-find openings within the duct system. To complete this method, all vents are closed off except for one access opening. 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 works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians administer a duct leakage test prior to and following aerosol sealing to measure leakage changes and ensure the method was successful.

Common Areas of Duct Leakage

The most common leakage area in duct systems is the joints. Ductwork involves numerous metal parts pressed together with tight fittings and metal bands, but these connections are almost never fully airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly expand and contract. Over time, this movement compromises the joints, forming gaps and leaks — which is exactly why duct leakage test is encouraged for new and older homes in Maurice River, NJ.

Many energy auditors evaluate duct leakage by feeling around the duct system and using a small tool to check the size of joint gaps. If your duct system was never sealed using mastic and approved tape, there is a high probability that air leakage is present.

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

To achieve a passing duct leakage result, your system should fall under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is absent. For new construction, a duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Maurice River, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. Meeting the 3–4 CFM requirement is fundamental not only for code adherence but for boosting your home’s long-term efficiency and comfort.

Your technician will also offer expert guidance on fixing leakage problems so you can earn a passing score, reduce utility costs, and enhance 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 our duct tester to the system’s unit or to the main return.

The ducts are then depressurized to 25 Pascals. With this pressure applied, we use the nanometer to measure how much leakage is present.
