Why Duct Leakage Test is Important In Bayonne, NJ

Many states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family properties and the 2018 International Energy Conservation Code for multi-family developments. The change will carry significant implications for home builders and HVAC contractors serving communities in the state. A Duct Leakage Test plus a Blower Door Test are now compulsory in newly constructed or renovated homes according to the 2015 regulations. Did you know that ductwork is a major cause of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can spike your energy costs, wear down your HVAC system, and spread dust and insulation throughout various parts of your home. 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 start conducting a duct leakage test in Bayonne, NJ, the technician seals all supply and return registers other than the main return or the air handler. A duct blaster — a precision-calibrated fan — is then fitted to the duct opening. By depressurizing the system, it makes all air leaks much easier to detect.

The duct blaster, working hand in hand with a precision pressure sensor, measures airflow and identifies leaks in the ductwork without impacting your home. A duct leakage test — sometimes known as a duct blaster test — shows exactly where your ducts are leaking air so you can apply the right sealing fixes.

duct leakage test is swift, clean, and carried out with no disturbance to residents. Most tests in Bayonne, NJ require only 30 to 60 minutes, yet the upgrades can improve your home’s comfort and efficiency well into the future.

How to Measure Duct Leakage

Duct leakage is tracked in cubic feet per minute (CFM) per 100 square feet of conditioned living area. Your technician uses a nanometer to measure tiny pressure differences, making it possible to determine how much air the ducts are losing. Understanding this number helps you detect issues, explore potential fixes, and determine if your home aligns with local energy code requirements in Bayonne, NJ.

Cost of Excessive Duct Leakage

If you’re dealing with rising utility bills, inconsistent room temperatures, or repeated HVAC issues, duct leakage could be the reason. According to ENERGY STAR, the majority of homes lose 20% to 30% of conditioned air through duct leaks. If outdoor hot or cold air infiltrates your system, your HVAC struggles to maintain temperatures, raising energy costs and lowering comfort.

Overworked equipment also increases the likelihood of breakdowns and drives up repair costs. Proper duct sealing helps protect the long-term performance of your HVAC system, increasing its lifespan and lowering future maintenance requirements.

Duct leaks can also bring dust, mold spores, excess moisture, and other impurities into the duct system. This can trigger more severe allergies, diminish indoor air quality, and create expensive structural problems behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC sets a requirement that all new homes feature ducts sealed completely with modern materials like mastic, foil tape, and insulation. But what if the leaks you’re dealing with are deep inside the walls or ceilings?

Aerosol sealing technology (AeroSeal) is designed to reach and seal hidden gaps throughout the duct system. 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 applies a fine aerosol sealant that fills tiny openings where standard sealing cannot reach.

This method is ideal for small to medium leaks. However, any large openings will still need manual sealing with mastic and tape. Technicians conduct duct leakage test before and after aerosol sealing to see how much the leakage dropped and ensure the treatment worked properly.

Common Areas of Duct Leakage

The most typical place where ducts leak air is at their joints. Ductwork is built from multiple metal sections pressed tightly with fittings and metal bands, yet these joints are rarely airtight.

As your HVAC system operates in varying temperatures across the year, the ducts undergo expansion and contraction. Over time, this movement leads to joint loosening, generating gaps and leaks — a clear reason duct leakage test is recommended for new and older homes in Bayonne, NJ.

Many energy auditors look for leaks by feeling the ducts and using a small tool to evaluate how wide the gaps at the joints are. If your duct system hasn’t been finished with mastic and approved tape, leaks are highly likely.

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

To achieve a passing duct leakage result, your system should stay under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it. For new construction, a duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Bayonne, NJ fails a duct leakage test, you are probably spending more than you should on heating and cooling — while also putting long-term stress on your HVAC system. Meeting the 3–4 CFM requirement is essential not only for code compliance but also for protecting your home’s energy efficiency and comfort.

Your technician will also share expert solutions for tackling leakage problems so you can pass the test, cut down utility expenses, and improve overall comfort and efficiency.

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 connect the duct tester either to the HVAC unit itself or a central return.

The ducts are then depressurized to a level of 25 Pascals. Once depressurized, the nanometer provides an accurate duct leakage reading.
