Why Duct Leakage Test is Important In Clayton borough, 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 several important implications for home builders and HVAC contractors operating within the state. A Duct Leakage Test in addition to a Blower Door Test is now required for new construction and remodeled homes under the 2015 rules. Did you know that duct systems can be major sources of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. This makes duct leakage test highly important for homes of any age. Read on to learn why duct leakage test matters and the benefits you can gain.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To perform a duct leakage test in Clayton borough, NJ, the technician begins by sealing every supply and return register except for the primary return or air handler unit. 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, aided by a precision pressure sensor, accurately measures airflow and reveals duct leaks without interrupting activities in your home. A duct leakage test — often known as a duct blaster test — exposes duct air loss, allowing you to apply the most effective sealing techniques.

duct leakage test is easy, clean, and unobtrusive for residents in the home. Most tests in Clayton borough, NJ are wrapped up in 30 to 60 minutes, with improvements that continue to boost comfort and efficiency for years.

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 monitor tiny pressure fluctuations that indicate how much air is leaking through the ducts. Understanding this number helps you identify problem areas, evaluate potential improvements, and determine whether your home meets local energy code requirements in Clayton borough, NJ.

Cost of Excessive Duct Leakage

If you’re struggling with expensive utility bills, inconsistent indoor temperatures, or continual HVAC problems, duct leakage might be the culprit. According to ENERGY STAR, the average household loses 20%–30% of conditioned air because of leaking ducts. Air from outside—whether hot or cold—entering your system forces your HVAC to work harder, increasing utility bills and reducing indoor comfort.

Overworked equipment also produces more frequent issues that require costly repairs. 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 permit dust, mold spores, extra moisture, and other airborne 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 requires that all new homes feature fully sealed duct systems utilizing updated, energy-efficient materials like mastic, foil tape, and insulation. But what happens when leaks are hidden deep inside walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To perform the technique, all vents are sealed except a single access opening. The HVAC system is isolated, and a machine is hooked into the duct system. It pressurizes the ducts and sprays a fine mist of sealant that fills tiny leaks and holes beyond the reach of conventional sealing.

This method is very effective for minor to moderate leaks. However, substantial openings may still need traditional sealing with mastic and tape. 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 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 heats and cools throughout the year, the ducts expand and contract. Over time, this movement causes the joints to loosen, opening gaps and leaks — making a duct leakage test beneficial for both new and older homes in Clayton borough, NJ.

Many energy auditors identify duct leakage by moving their hands along the ducts and using a small tool to check the width of joint openings. If your duct system isn’t sealed with mastic and approved tape, there’s a good chance that leaks are occurring.

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

To achieve a passing duct leakage result, your system needs to register under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it attached. For new construction, no home can receive an occupancy certificate without first passing a duct leakage test.

If your home in Clayton borough, NJ doesn’t achieve a passing duct leakage score, you’re likely overspending on heating and cooling — and putting extended strain on your HVAC unit. 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 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 all ducts and registers being sealed using duct mask tape on the supply and return sides.

After the registers are sealed we attached the duct tester to either the unit itself or a main return.

The ducts are then placed under 25 Pascals of negative pressure. With the ducts depressurized, we obtain the leakage reading using the nanometer.
