Guarantee your HVAC system runs efficiently and adheres to local requirements with quality duct leakage test in Bound Brook, NJ. Our certified technicians find and measure ductwork air leaks, allowing homeowners and builders to improve indoor comfort, reduce energy waste, and satisfy state standards.

Why Duct Leakage Test is Important In Bound Brook, NJ

Many states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family properties and the 2018 International Energy Conservation Code for multi-family developments. The change will have some significant implications for home builders and HVAC contractors operating in the state. A Duct Leakage Test and a mandatory Blower Door Test are now required for all new construction or remodeled homes under the 2015 regulatory standards. Did you know that duct systems can be major sources of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can increase your energy costs, overwork your HVAC system, and distribute insulation particles and dust around your home. This makes duct leakage test vital for homes both old and newly built. Keep reading to find out why duct leakage test matters and what benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin the process of a duct leakage test in Bound Brook, NJ, your technician seals off all supply and return registers apart from 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 works in sync with a precision pressure sensor to assess airflow and find duct leaks without disturbing your living space. A duct leakage test — sometimes called a duct blaster test — reveals where your ducts are losing air so you can determine the most effective sealing solutions.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Bound Brook, 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 quantified in cubic feet per minute (CFM) for each 100 square feet of conditioned living space. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number helps you pinpoint leakage points, think through potential improvements, and verify your home’s adherence to local energy code requirements in Bound Brook, 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, homes with leaky ducts routinely lose 20% to 30% of conditioned air. When your system pulls in hot or cold outdoor air, the HVAC unit has to work harder, driving up energy usage and reducing comfort indoors.

Overworked equipment also leads to recurring breakdowns and higher repair expenses. 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 pull dust, mold spores, excess moisture, and various contaminants into 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 requires newly built homes to install fully sealed duct systems using advanced materials like mastic, foil tape, and quality insulation. But what about leaks located deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) gives technicians a way to reach concealed duct leaks without opening walls or ceilings. 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 sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method performs well for small and medium leaks. However, larger openings typically require manual sealing with mastic and tape. Technicians do a duct leakage test before and after aerosol sealing to calculate how much leakage has been reduced and validate the results.

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 shifts between hot and cold cycles all year long, the ductwork expands and contracts. Over time, this movement leads the joints to loosen, resulting in gaps and leaks — making a duct leakage test important for new and older homes in Bound Brook, NJ.

Many energy auditors inspect duct leakage by feeling the ducts and using a small tool to determine how wide the gaps are between joints. If your duct system is missing mastic and approved tape sealing, there’s a significant chance that air leakage is happening.

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

To achieve a passing duct leakage result, your system should stay under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it. For new construction, a duct leakage test must be successfully passed before the home can obtain an occupancy certificate.

If your home in Bound Brook, NJ cannot achieve a passing duct leakage score, you are likely wasting money on heating and cooling — and increasing wear on your HVAC system over time. Meeting the 3–4 CFM requirement is needed not only for passing inspections, but also for improving home comfort and energy efficiency.

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

After the registers are sealed, we set up the duct tester by attaching it to the unit or a main return.

The ducts are then lowered to a depressurized level of 25 Pascals. With the system at that pressure, the nanometer is used to read the duct leakage.
