Duct Leakage Test in Ocean township, NJ

Maintain top HVAC efficiency and stay aligned with local energy codes using trusted duct leakage test in Ocean township, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Ocean township, 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 bring notable implications for home builders and HVAC contractors working throughout the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under the 2015 regulations. Did you know that ducts often contribute significantly to air leakage problems in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can cause your energy bills to rise, strain your HVAC system, and move dust and insulation around your living spaces. This makes duct leakage test necessary for homeowners with either older or newly built homes. Read ahead to see why duct leakage test is important and what you gain from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in Ocean township, NJ, the technician seals all supply and return registers other than the main return or the air handler. A specially calibrated duct blaster fan is then secured to the opening. Its job is to depressurize the duct system, allowing air leaks to reveal themselves clearly.

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 labeled as a duct blaster test — finds where your ducts are leaking air so you can decide on the best sealing strategy.

duct leakage test is prompt, clean, and does not interrupt residents’ activities. Most tests in Ocean township, NJ are completed within 30 to 60 minutes, and the improvements can benefit your home’s comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is specified in cubic feet per minute (CFM) for each 100 square feet of conditioned space. 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 identify concerns, evaluate upgrade opportunities, and determine whether your home fulfills local energy code requirements in Ocean township, NJ.

Cost of Excessive Duct Leakage

If you’re facing higher energy bills, uneven heating or cooling, or recurring HVAC repairs, duct leakage could be to blame. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also puts extra stress on the system, resulting in breakdowns and increased repair costs. Proper duct sealing helps preserve the long-term efficiency of your HVAC system, boosting its lifespan and cutting down on regular maintenance needs.

Duct leaks can also allow dust, mold spores, excess moisture, and other contaminants into the duct system. This can negatively influence allergies, weaken indoor air quality, and lead to expensive long-term damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates fully sealed duct systems in new homes, made from energy-efficient materials like mastic, foil tape, and proper insulation. But what about leaks that occur deep behind walls or ceilings out of sight?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. 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 sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians perform a duct leakage test both before and after aerosol sealing to determine how much leakage has decreased and confirm the treatment worked.

Common Areas of Duct Leakage

The most typical location for air to escape from ducts is at the joints. Duct systems are built from multiple metal pieces pressed together with tight fittings and metal bands, but these joints are seldom completely airtight.

As your HVAC system heats and cools during seasonal changes, the ductwork expands and then contracts. Over time, this movement weakens the joints, creating gaps and leaks — a key reason duct leakage test is recommended for new and older homes in Ocean township, NJ.

Many energy auditors locate duct leakage by touching the ductwork and using a small tool to measure the width of separation between joints. 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 read under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler. For new construction, passing a duct leakage test is required before a home can receive an occupancy certificate.

If your home in Ocean township, NJ does not pass a duct leakage test, you are likely paying more than necessary for heating and cooling — and placing long-term strain on your HVAC equipment. Meeting the 3–4 CFM requirement is critical not just for code compliance, but also for defending your home’s comfort and energy performance.

Your technician will also offer professional recommendations to tackle leakage issues so you can secure a passing score, reduce utility costs, and strengthen 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 attach our duct tester to the system’s unit or to the main return.

The ducts are then depressurized to 25 Pascals. At that point, the nanometer allows us to get an accurate duct leakage measurement.
