Duct Leakage Test in South Toms River borough, NJ

Ensure long-term HVAC performance and code compliance with expert duct leakage test in South Toms River borough, NJ. Our certified technicians detect and measure air leakage in ductwork, supporting homeowners and builders in improving comfort, minimizing wasted energy, and meeting state requirements.

Why Duct Leakage Test is Important In South Toms River borough, 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 present notable implications for home builders and HVAC contractors active throughout the state. 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 ducts often contribute significantly to air leakage problems in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can push your energy bills higher, pressure your HVAC system, and spread dust and insulation inside your house. 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 start a duct leakage test in South Toms River borough, NJ, the technician will close and seal every supply and return register except the main return or air handler. 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 operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. A duct leakage test — often known as a duct blaster test — exposes duct air loss, allowing you to apply the most effective sealing techniques.

duct leakage test is straightforward, clean, and designed to be non-intrusive for residents. Most tests in South Toms River borough, NJ are completed in just 30 to 60 minutes, while the benefits to comfort and efficiency can last long-term.

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 uses a nanometer to evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number lets you identify inefficiencies, weigh improvement options, and confirm your home’s compliance with local energy code requirements in South Toms River borough, NJ.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, a large portion of homes lose between 20% and 30% of conditioned air due to leaky ducts. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also leads to more breakdowns and 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 introduce dust, mold spores, excess humidity, and other 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 specifies that newly constructed homes must use fully sealed duct systems with modern, efficient materials such as mastic, foil tape, and insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. To implement this method, every vent is covered except one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and distributes a fine aerosolized sealant that seals small openings traditional methods cannot reach.

This method excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with mastic and tape. Technicians run a duct leakage test before and after aerosol sealing to quantify the reduction in leakage and verify the success of the process.

Common Areas of Duct Leakage

The most common area where ducts leak air is around the joints. Ductwork uses several metal parts pressed together with tight fittings and metal bands, though these points are rarely airtight.

As your HVAC system moves through annual heating and cooling cycles, the ductwork expands and then contracts. Over time, this movement causes the joints to loosen, opening gaps and leaks — making a duct leakage test beneficial for both new and older homes in South Toms River borough, NJ.

Many energy auditors detect duct leakage by physically checking the ducts and using a small tool to assess the width of joint gaps. 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, an occupancy certificate cannot be issued unless the home passes a duct leakage test.

If your home in South Toms River borough, NJ falls short in a duct leakage test, you are probably paying extra for heating and cooling — and placing lasting pressure on your HVAC equipment. Meeting the 3–4 CFM requirement matters not only for code compliance, but also for protecting your home’s comfort and reducing energy waste.

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 by covering all ducts and registers with duct mask tape on both the supply and return sides.

After the registers are sealed, we position the duct tester on the HVAC unit or on a primary return.

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
