Duct Leakage Test in Monroe township, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Monroe township, NJ. Our certified technicians identify and quantify air leaks in duct systems so homeowners and builders can optimize comfort, reduce energy waste, and meet state-level requirements.

Why Duct Leakage Test is Important In Monroe township, NJ

Across the country, states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under the 2015 regulations. Did you know that ducts are a leading factor in home air leakage 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 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 conduct a proper duct leakage test in Monroe township, NJ, your technician first seals all supply and return registers except the main return or air handler. A specially calibrated fan called a duct blaster is then connected to the opening. This fan depressurizes the duct system, making it easier to pinpoint exactly where air is leaking.

The duct blaster and its precision pressure sensor work together to measure airflow and detect duct leaks without causing any disruption in your home. A duct leakage test — sometimes referred to as a duct blaster test — uncovers air leaks in your ductwork so you can determine the ideal sealing approach.

duct leakage test is quick, clean, and non-intrusive for residents. Most tests in Monroe township, NJ are completed in roughly 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to capture subtle pressure changes, allowing accurate measurement of duct air leakage. Understanding this number helps you pinpoint leakage points, think through potential improvements, and verify your home’s adherence to local energy code requirements in Monroe township, 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 typical home loses between 20% and 30% of its conditioned air due to duct 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 results in more frequent breakdowns and expensive repair bills. 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 bring dust, mold spores, excess moisture, and other impurities into the duct system. This can negatively influence allergies, weaken indoor air quality, and lead to expensive long-term damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC instructs that new homes incorporate fully sealed duct systems using high-efficiency materials, including mastic, foil tape, and insulation. But what if the leaks are buried far inside your walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and emits a fine aerosol sealant that fills tiny gaps and holes that standard sealing methods can’t access.

This method is great for handling small to medium leaks. However, larger holes often require manual sealing with mastic and tape. Technicians administer a duct leakage test prior to and following aerosol sealing to measure leakage changes and ensure the method was successful.

Common Areas of Duct Leakage

The most frequent source of duct air leakage is the joints. Ductwork uses many metal pieces pressed together with tight fittings and metal bands, but these joining points are rarely airtight.

As your HVAC system adjusts temperatures throughout the year, the ducts go through expansion and contraction. Over time, this movement makes joints shift and loosen, forming gaps and leaks — which is why a duct leakage test is advised for homes old and new in Monroe township, NJ.

Many energy auditors evaluate duct leakage by feeling around the duct system and using a small tool to check the size of joint gaps. If your duct system lacks sealing with mastic and approved tape, there is a strong chance that leakage is present.

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

To achieve a passing duct leakage result, your system needs to measure under 4 CFM per 100 square feet when the air handler is included, or 3 CFM per 100 square feet when it is not. For new construction, the duct leakage test must be passed prior to the home being approved for an occupancy certificate.

If your home in Monroe township, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. 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 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 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 reduced to a depressurized state of 25 Pascals. With them depressurized, the nanometer gives us the duct leakage reading.
