Duct Leakage Test in Paterson, NJ

Guarantee your HVAC system runs efficiently and adheres to local requirements with quality duct leakage test in Paterson, NJ. Our certified technicians trace and measure duct leaks, supporting homeowners and builders in enhancing comfort, lowering energy waste, and staying compliant with state codes.

Why Duct Leakage Test is Important In Paterson, NJ

In most states and municipalities, the 2015 IECC, International Energy Conservation Code is required for single-family homes, while the 2018 International Energy Conservation Code is required for multi-family homes. The change will impose meaningful implications on home builders and HVAC contractors working regionally within the state. A Duct Leakage Test as well as the required Blower Door Test must now be performed on new or remodeled homes following the 2015 regulations. Did you know that ducts are among the biggest contributors to air leakage in homes all across Pennsylvania, New Jersey, and Delaware? Leaked air can increase monthly energy costs, stress your HVAC system, and scatter dust and insulation across your living areas. This makes duct leakage test indispensable no matter the age of your home. Continue reading to understand why duct leakage test is important and the benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start a duct leakage test in Paterson, NJ, the technician will close and seal every supply and return register except the main return or air handler. A specially calibrated duct blaster is then installed onto the opening. The fan lowers the pressure inside the ducts, helping reveal any leakage points.

The duct blaster teams up with a precision pressure sensor to measure airflow accurately and locate duct leaks without affecting your home. A duct leakage test — frequently called a duct blaster test — reveals air escape points in your ducts, guiding you toward the best sealing options.

duct leakage test is easy, clean, and unobtrusive for residents in the home. Most tests in Paterson, 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 reported in cubic feet per minute (CFM) per 100 square feet of conditioned home area. Your technician relies on a nanometer to read slight pressure variations that show the amount of air leaking through the duct system. Understanding this number allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Paterson, NJ.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, most households lose 20% to 30% of their heated or cooled air because of duct leaks. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also makes breakdowns more common and repairs more expensive. Proper duct sealing helps ensure the long-term stability of your HVAC system, extending its lifespan and reducing future maintenance work.

Duct leaks can also introduce dust, mold spores, excess humidity, and other contaminants into the duct system. This can escalate allergies, lower the overall air quality indoors, and lead to costly damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to use fully sealed duct systems crafted from up-to-date, efficient materials such as mastic, foil tape, and insulation. But what about leaks that lie far within enclosed wall or ceiling spaces?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. To conduct this method, all vents are blocked except for one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method is effective at treating small to medium leaks. However, big openings may still need to be addressed with manual mastic-and-tape sealing. Technicians use before-and-after duct leakage tests to measure improvement and make sure the aerosol sealing process 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 changes between heating and cooling during the year, the ducts naturally expand and shrink. 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 Paterson, NJ.

Many energy auditors detect leaks by checking the duct surfaces by hand and using a small tool to measure joint gap width. 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, passing the duct leakage test is a necessary step before securing an occupancy certificate.

If your home in Paterson, 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 essential not only for following building code, but for keeping your home comfortable and energy-efficient.

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 by taping off all ducts and registers with duct mask tape on the supply and return sides.

After the registers are sealed, we secure the duct tester to the HVAC unit or to a main return.

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
