Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in North Wildwood, NJ. Our certified technicians measure and identify ductwork air leaks, assisting homeowners and builders in boosting comfort, limiting energy waste, and maintaining state compliance.

Why Duct Leakage Test is Important In North Wildwood, NJ

Across different states and municipalities, the 2015 IECC, International Energy Conservation Code regulates single-family structures, and the 2018 International Energy Conservation Code is used for multi-family structures. The change will have some significant implications for home builders and HVAC contractors operating in the state. A Duct Leakage Test and a mandatory Blower Door Test are now required for all new construction or remodeled homes under the 2015 regulatory standards. Did you know that duct systems contribute heavily to air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test an important requirement for homes regardless of age. Keep reading to understand why duct leakage test is necessary and how it can help you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin the process of a duct leakage test in North Wildwood, NJ, your technician seals off all supply and return registers apart from the main return or air handler. A specially calibrated fan called a duct blaster is then connected to the opening. This fan depressurizes the duct system, making it easier to pinpoint exactly where air is leaking.

The duct blaster operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. A duct leakage test — sometimes called a duct blaster test — detects air loss in the duct system, allowing you to apply the most suitable sealing solutions.

duct leakage test is quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in North Wildwood, NJ are completed in roughly 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency long-term.

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 measure tiny pressure differences, making it possible to determine how much air the ducts are losing. Understanding this number helps you locate trouble spots, review possible upgrades, and see if your home complies with local energy code requirements in North Wildwood, 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 typical home loses between 20% and 30% of its conditioned air due to duct leaks. If hot or cold air from outdoors enters your system, your HVAC works harder than necessary, causing energy costs to rise and comfort to fall.

Overworked equipment also makes breakdowns more common and repairs more expensive. 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 enable dust, mold spores, elevated moisture, and unwanted contaminants to infiltrate the duct system. This can aggravate allergies, lower indoor air quality, and eventually lead to costly structural damage hidden behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires all newly constructed homes to have fully sealed ductwork with modern, energy-saving materials such as mastic, foil tape, and insulation. But what if those leaks are tucked away behind walls or ceilings?

Aerosol sealing technology (AeroSeal) can identify and seal leaks that lie deep inside ductwork. To perform the process, technicians seal all vents but leave one access point open. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method provides strong results for small and medium leaks. However, significant openings may still require mastic and tape by hand. 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 likely place for ducts to leak air is through their joints. Ductwork involves multiple metal pieces pressed together with secure fittings and metal bands, yet these connections are rarely perfectly airtight.

As your HVAC system transitions between warm and cool air 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 North Wildwood, 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 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 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, an occupancy certificate cannot be issued unless the home passes a duct leakage test.

If your home in North Wildwood, 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 crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

Your technician will also give informed guidance on addressing leakage problems, enabling you to pass the test, reduce energy bills, and enhance your home’s 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 hook the duct tester to the HVAC unit or a main return.

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