Duct Leakage Test in Ringwood, NJ

Make sure your HVAC system is performing efficiently and meeting local standards with thorough duct leakage test in Ringwood, NJ. Our certified technicians locate and quantify air leaks in duct systems so homeowners and builders can enhance comfort, lower energy loss, and comply with state regulations.

Why Duct Leakage Test is Important In Ringwood, NJ

States and municipalities are using the 2015 IECC, International Energy Conservation Code for single-family construction and the 2018 International Energy Conservation Code for multi-family construction. The change will impose meaningful implications on home builders and HVAC contractors working regionally within 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 among the biggest contributors to air leakage in homes all across Pennsylvania, New Jersey, and Delaware? Leaked air can elevate your energy bills, make your HVAC system work harder, and distribute insulation fibers and dust 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 Ringwood, NJ, your technician first seals all supply and return registers except the main return or air handler. A calibrated duct blaster fan is then mounted to the opening. This fan creates negative pressure inside the ducts, making air leakage locations easier to find.

The duct blaster joins forces with a precision pressure sensor to monitor airflow and pinpoint leak points in the ducts without disturbing your home. A duct leakage test — sometimes identified as a duct blaster test — shows where your ducts lose air, helping you plan the right sealing approach.

duct leakage test is simple, clean, and minimally invasive for residents. Most tests in Ringwood, NJ finish within 30 to 60 minutes, and the benefits to your home’s comfort and efficiency can last for years.

How to Measure Duct Leakage

Duct leakage is calculated in cubic feet per minute (CFM) for every 100 square feet of conditioned space. Your technician uses a nanometer to detect small pressure differences, which indicate how much air is leaking through the ducts. Understanding this number helps you spot leakage issues, evaluate corrective measures, and determine if your home is meeting local energy code requirements in Ringwood, 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, the average duct system loses between 20% and 30% of its conditioned air due to leaks. Hot or cold outside air creeping into your system forces the HVAC to work inefficiently, increasing energy spending and reducing comfort.

Overworked equipment also leads to recurring breakdowns and higher repair expenses. Proper duct sealing helps protect and extend the long-term lifespan of your HVAC system, minimizing the need for repeated maintenance.

Duct leaks can also allow the entry of dust, mold spores, moisture, and a range of contaminants into the duct system. This can heighten allergy issues, compromise indoor air quality, and slowly cause expensive structural damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC calls for new homes to include duct systems that are completely sealed using efficient materials such as mastic, foil tape, and insulation. But what happens when air leaks are concealed deep in the walls or ceilings?

Aerosol sealing technology (AeroSeal) helps target hard-to-reach openings deep within ducts. To apply this method, every vent is sealed aside from one access point. The HVAC system is isolated, and a machine is connected to the ducts. It pressurizes the ducts and distributes an ultra-fine aerosol sealant to fill small gaps and holes that manual sealing methods can’t access.

This method is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians perform pre- and post-aerosol sealing duct leakage tests to measure the improvement and confirm treatment effectiveness.

Common Areas of Duct Leakage

The most usual area for air leakage in ducts is at the joints. Ductwork includes various metal pieces pressed together using tight fittings and metal bands, but these connections are hardly ever airtight.

As your HVAC system moves through annual heating and cooling cycles, the ductwork expands and then contracts. 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 Ringwood, 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 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 should fall under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is absent. For new construction, you must pass a duct leakage test before the home can be approved for an occupancy certificate.

If your home in Ringwood, NJ cannot pass a duct leakage test, you are likely wasting money on heating and cooling — and causing long-term wear on your HVAC system. Meeting the 3–4 CFM requirement is important not only for the inspector, but also for maximizing energy efficiency and comfort in your home.

Your technician will also share expert recommendations for fixing leakage problems, helping you achieve a passing score, save on utilities, and improve home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by securing duct mask tape over every duct and register on the supply and return sides.

After the registers are sealed, we position the duct tester on the HVAC unit or on a primary return.

The ducts are then depressurized until they reach 25 Pascals. With them depressurized, the nanometer measures the amount of leakage.
