Guarantee your HVAC system runs efficiently and adheres to local requirements with quality duct leakage test in Bridgewater, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Bridgewater, NJ

Many states and municipalities oversee single-family buildings under the 2015 IECC, International Energy Conservation Code and multi-family buildings under the 2018 International Energy Conservation Code. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test together with a Blower Door Test has become mandatory for any newly constructed or remodeled home under the 2015 code. Did you know that ductwork often causes some of the highest levels of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can lead to rising energy bills, added strain on your HVAC system, and unwanted insulation and dust spreading through your home. This makes duct leakage test valuable for new and existing homes alike. Read on to learn why duct leakage test is important and how it can help you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Bridgewater, NJ, your technician first seals all supply and return registers except the main return or air handler. A duct blaster, which is a specially calibrated fan, is then installed at the opening. The fan depressurizes the ducts, helping identify all points where air may be escaping.

The duct blaster system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. 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 rapid, clean, and performed without inconvenience to residents. Most tests in Bridgewater, NJ are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

How to Measure Duct Leakage

Duct leakage is specified in cubic feet per minute (CFM) for each 100 square feet of conditioned space. Your technician uses a nanometer to sense slight pressure changes, showing precisely how much air is escaping through the ductwork. Understanding this number helps you recognize where issues exist, plan meaningful improvements, and check your home against local energy code requirements in Bridgewater, NJ.

Cost of Excessive Duct Leakage

If elevated utility bills, shifting temperatures, or repeated HVAC issues occur in your home, duct leakage may be the factor behind them. According to ENERGY STAR, the average home loses 20% to 30% of conditioned air through 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 puts extra stress on the system, resulting in breakdowns and increased repair costs. Proper duct sealing helps keep your HVAC system healthy over the long run, prolonging its lifespan and lowering continued maintenance needs.

Duct leaks can also pull in dust, mold spores, moisture, and numerous 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 ensures that new homes are built with duct systems sealed entirely using efficient materials such as mastic, foil tape, and insulation. But what happens when leaks are hidden deep inside walls or ceilings?

Aerosol sealing technology (AeroSeal) helps seal hard-to-find openings within the duct system. To execute this method, all vents are sealed shut except a single access point. The HVAC system is isolated, and a machine is attached to the duct network. It pressurizes the ducts and distributes a fine aerosolized sealant that seals small openings traditional methods cannot reach.

This method handles small to medium leaks very effectively. However, large openings may still require traditional mastic and tape sealing. 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 common location for air leakage in ducts is the joints. Ductwork includes several metal sections pressed together with tight fittings and metal bands, but those connections are almost never airtight.

As your HVAC system adjusts temperatures throughout the year, the ducts go through expansion and contraction. 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 Bridgewater, NJ.

Many energy auditors examine duct leakage by touching the ducts and using a small tool to measure the gap width between joints. If your duct system has not been properly sealed with mastic and approved tape, it’s very likely that leakage exists.

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, passing a duct leakage test is required before a home can receive an occupancy certificate.

If your home in Bridgewater, NJ doesn’t pass its duct leakage evaluation, you’re likely paying more for temperature control — and contributing to long-term HVAC strain. Meeting the 3–4 CFM requirement is necessary not only for meeting code standards but also for ensuring strong energy efficiency and indoor comfort.

Your technician will also offer professional recommendations to tackle leakage issues so you can secure a passing score, reduce utility costs, and strengthen home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with sealing each duct and register using duct mask tape on the supply and return sides.

After the registers are sealed, we mount the duct tester onto the unit or onto a 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.
