Duct Leakage Test in Toms River, NJ

Protect system efficiency and meet local building codes by choosing certified duct leakage test in Toms River, NJ. Our certified technicians locate and quantify air leaks in duct systems so homeowners and builders can enhance comfort, lower energy loss, and comply with state regulations.

Why Duct Leakage Test is Important In Toms 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 impose meaningful implications on home builders and HVAC contractors working regionally 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 frequently the biggest contributors to home air loss in 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 crucial for new and old homes alike. Keep reading to learn why duct leakage test is important and how you can benefit from them.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To commence a duct leakage test in Toms River, NJ, your technician will seal every supply and return register except the primary return or air handler. A specially calibrated fan, known as a duct blaster, is then attached to the opening. The purpose of this fan is to depressurize the duct system, creating the ideal conditions to identify where air is escaping.

The duct blaster uses its precision pressure sensor partner to measure airflow and uncover duct leaks without causing any home disruption. A duct leakage test — widely known as a duct blaster test — pinpoints air leakage in your ducts so you can choose the best sealing methods.

duct leakage test is fast, debris-free, and completely resident-friendly. Most tests in Toms River, NJ are done within 30 to 60 minutes, with improvements that strengthen comfort and efficiency for years to come.

How to Measure Duct Leakage

Duct leakage is measured in cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a nanometer to detect small pressure differences, which indicate how much air is leaking 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 Toms 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, many homes lose as much as 20% to 30% of conditioned air through duct leaks. Hot or cold air entering from outside increases the workload on your HVAC system, leading to higher energy bills and a drop in comfort.

Overworked equipment also leads to more breakdowns and costly repairs. Proper duct sealing helps support the long-term durability of your HVAC system, lengthening its lifespan and minimizing ongoing maintenance demands.

Duct leaks can also allow dust, mold spores, excess moisture, and other contaminants into the duct system. This can make allergies worse, impact indoor air quality, and result in costly structural damage behind walls or ceilings as time passes.

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 do you do about leaks that sit deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) gives technicians a way to reach concealed duct leaks without opening walls or ceilings. 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 applies a fine aerosol sealant that fills tiny openings where standard sealing cannot reach.

This method provides strong results for small and medium leaks. However, significant openings may still require mastic and tape by hand. Technicians carry out a duct leakage test before and after aerosol sealing to assess how much leakage has improved and ensure the treatment was effective.

Common Areas of Duct Leakage

The most typical location for air to escape from ducts is at the joints. Duct systems are built from multiple metal pieces pressed together with tight fittings and metal bands, but these joints are seldom completely airtight.

As your HVAC system heats and cools throughout the year, the ducts 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 Toms River, NJ.

Many energy auditors investigate duct leakage by running their hands over the ducts and using a small tool to determine the width of joint gaps. If your duct system wasn’t sealed using mastic and approved tape, there is a strong chance that air 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 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, a duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Toms River, NJ does not meet the duct leakage requirement, you’re likely paying elevated heating and cooling costs — and overburdening your HVAC system. 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 applying duct mask tape to seal every duct and register on both the supply and return sides.

After the registers are sealed, we fasten the duct tester to the unit or to a 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.
