Why Duct Leakage Test is Important In Perth Amboy, 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 create considerable implications for home builders and HVAC contractors carrying out projects in the state. 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 ducts are responsible for a large share of air leakage issues in homes in Pennsylvania, New Jersey, and Delaware? Leaked air can cause your energy bills to rise, strain your HVAC system, and move dust and insulation around your living spaces. This makes duct leakage test important for all types of homes, whether new or old. Continue reading to learn why duct leakage test is essential and how you can benefit.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To prepare for a duct leakage test in Perth Amboy, NJ, the technician seals every supply and return register, leaving only the main return or air handler unsealed. 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 operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. 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 simple, clean, and minimally invasive for residents. Most tests in Perth Amboy, 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 register small pressure differences, which help calculate how much air is leaking from the ducts. Understanding this number enables you to recognize problem areas, consider efficiency improvements, and verify that your home meets local energy code requirements in Perth Amboy, NJ.

Cost of Excessive Duct Leakage

If you’re experiencing spikes in utility bills, uncomfortable temperature variations, or ongoing HVAC repair needs, duct leakage may be to blame. According to ENERGY STAR, homes with leaky ducts routinely lose 20% to 30% of conditioned air. When outside hot or cold air seeps into your system, your HVAC must compensate, leading to higher energy costs and diminished comfort.

Overworked equipment also leads to recurring breakdowns and higher repair expenses. Proper duct sealing helps maintain the long-term health of your HVAC system, extending its lifespan and reducing ongoing maintenance needs.

Duct leaks can also let in dust, mold spores, added moisture, and other harmful contaminants. This can make allergies more severe, reduce the quality of indoor air, and produce costly structural harm behind walls or ceilings as time progresses.

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

Aerosol sealing technology (AeroSeal) is used to address openings concealed inside duct systems. 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 releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method seals small to medium leaks effectively. However, large gaps may still call for manual sealing using mastic and tape. Technicians use a duct leakage test before and after aerosol sealing to evaluate how much leakage has been lowered and verify the results.

Common Areas of Duct Leakage

The most common place for ducts to leak air is through the joints. Ductwork is made of multiple metal pieces pressed together using tight fittings and metal bands, but these connections are rarely airtight.

As your HVAC system adjusts temperatures throughout the year, the ducts go through expansion and contraction. Over time, this movement compromises the joints, forming gaps and leaks — which is exactly why duct leakage test is encouraged for new and older homes in Perth Amboy, NJ.

Many energy auditors locate duct leakage by touching the ductwork and using a small tool to measure the width of separation between joints. If your duct system does not include sealing with mastic and approved tape, leakage is highly likely.

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

To achieve a passing duct leakage result, your system must come in under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is removed. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Perth Amboy, NJ doesn’t receive a passing duct leakage result, you are likely overpaying for heating and cooling — and putting significant long-term strain on your HVAC setup. Meeting the 3–4 CFM requirement is important not just for compliance, but for safeguarding your home’s comfort and long-term energy efficiency.

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 covering all ducts and registers with duct mask tape on both the supply and return sides.

After the registers are sealed, we install the duct tester on the unit or on 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.
