Duct Leakage Test in Brick, NJ

Make sure your HVAC system performs at its best and satisfies local energy standards with certified duct leakage test in Brick, 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 Brick, NJ

Across many states and municipalities, the 2015 IECC, International Energy Conservation Code applies to single-family homes, while the 2018 International Energy Conservation Code governs multi-family buildings. The change will produce important implications for home builders and HVAC contractors functioning within the state. A Duct Leakage Test plus the required Blower Door Test are now necessary for newly built or remodeled homes in line with the 2015 regulations. 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 an important requirement for homes regardless of age. Keep reading to understand why duct leakage test is necessary and how it can help you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate testing, your technician will seal all supply and return registers except for the main return or air handler during a duct leakage test in Brick, NJ. 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 pairs with a precision pressure sensor to measure airflow and identify leak locations in the ducts without disrupting your home. A duct leakage test — often described as a duct blaster test — identifies leaking areas in your ducts so you can determine the most efficient sealing fix.

duct leakage test is quick, clean, and non-intrusive for residents. Most tests in Brick, NJ take just 30 to 60 minutes, and the resulting improvements can enhance your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is monitored in cubic feet per minute (CFM) per 100 square feet of the conditioned sections of 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 gives you insight into problem areas, helps you plan improvements, and ensures your home meets local energy code requirements in Brick, NJ.

Cost of Excessive Duct Leakage

If you are experiencing high utility bills, uneven temperatures, or frequent HVAC repairs, duct leakage may be the cause. According to ENERGY STAR, the average duct system loses between 20% and 30% of its conditioned air due to leaks. Hot or cold outside air entering your system forces your HVAC system to work harder, driving up energy costs and reducing comfort.

Overworked equipment also causes components to fail more often, leading to costly repairs. Proper duct sealing helps uphold the long-term performance of your HVAC system, stretching its lifespan and decreasing routine maintenance demands.

Duct leaks can also cause dust, mold spores, and excess moisture — along with other contaminants — to infiltrate the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration behind walls or ceilings.

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 about leaks that lie far within enclosed wall or ceiling spaces?

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

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians conduct duct leakage test before and after aerosol sealing to see how much the leakage dropped and ensure the treatment worked properly.

Common Areas of Duct Leakage

The most typical place for ducts to lose air is at the joints. Ductwork consists of different metal sections pressed together with tight fittings and metal bands, yet these joints are not usually 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, creating gaps and leaks — which is why a duct leakage test is recommended for both new and older homes in Brick, 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 is unsealed with mastic and approved tape, air leakage is almost certainly occurring.

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

To achieve a passing duct leakage result, your system must measure under 4 CFM per 100 square feet with the air handler in place, or 3 CFM per 100 square feet if the air handler is not installed. For new construction, a passing duct leakage test is essential before the home can qualify for an occupancy certificate.

If your home in Brick, NJ does not meet duct leakage standards, you are likely overpaying for heating and cooling — and adding unnecessary strain to your HVAC equipment. Meeting the 3–4 CFM requirement is crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

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 technicians sealing all ducts and registers using duct mask tape on the supply and return sides.

After the registers are sealed, we connect the duct tester either to the HVAC unit itself or a central return.

The ducts are then placed under 25 Pascals of negative pressure. With the ducts depressurized, we obtain the leakage reading using the nanometer.
