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 Bayville, 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 generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test and a required Blower Door Test are now part of the compliance process for new construction and remodeled homes under the 2015 regulations. Did you know that duct systems can be major sources of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can increase your energy costs, overwork your HVAC system, and distribute insulation particles and dust around your home. This makes duct leakage test an essential part of maintaining both new and older homes. Keep reading to discover why duct leakage test is important and how it can support your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Bayville, NJ, your technician first seals all supply and return registers except the main return or air handler. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

The duct blaster and its precision pressure sensor work together to measure airflow and detect duct leaks without causing any disruption 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 efficient, mess-free, and completely non-intrusive for residents. Most tests in Bayville, NJ finish in 30 to 60 minutes, and the upgrades continue benefiting your home’s comfort and efficiency long after.

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 register small pressure differences, which help calculate how much air is leaking from the ducts. Understanding this number helps you identify problem areas, evaluate potential improvements, and determine whether your home meets local energy code requirements in Bayville, NJ.

Cost of Excessive Duct Leakage

If you’re encountering increased energy bills, temperature inconsistencies, or constant HVAC repairs, duct leakage could be the source. According to ENERGY STAR, most households lose 20% to 30% of their heated or cooled air because of duct leaks. Hot or cold outside air leaking in makes your HVAC system work more than it should, driving up energy costs and diminishing comfort.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps sustain your HVAC system’s long-term condition, increasing its operational lifespan and decreasing 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 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 do you do about leaks that sit deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) provides a way to seal concealed openings inside the duct system. To implement this method, every vent is covered except one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and pushes a fine aerosol sealant through them, sealing small holes that ordinary sealing methods can’t reach.

This method performs well for small and medium leaks. However, larger openings typically require manual sealing with mastic and tape. Technicians conduct a duct leakage test before and after aerosol sealing to measure how much the leakage has been reduced and ensure the treatment is successful.

Common Areas of Duct Leakage

The most usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly expand and contract. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Bayville, NJ, new or older, benefit from duct leakage test.

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 is missing mastic and approved tape sealing, there’s a significant chance that air leakage is happening.

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

To achieve a passing duct leakage result, your system has to be under 4 CFM per 100 square feet when the air handler is in place, or 3 CFM per 100 square feet without it installed. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Bayville, NJ does not meet duct leakage standards, you are likely overpaying for heating and cooling — and adding unnecessary strain to your HVAC equipment. 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 professional advice on resolving leakage issues to help you achieve a passing score, cut down utility bills, and boost your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with all the ducts and registers sealed tightly using duct mask tape on both sides—supply and return.

After the registers are sealed, we attach the duct tester directly to the unit or to one primary return.

The ducts are then depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
