Duct Leakage Test in Long Beach, NJ

Ensure long-term HVAC performance and code compliance with expert duct leakage test in Long Beach, NJ. Our certified technicians evaluate and measure air leaks in duct systems, helping homeowners and builders enhance comfort, decrease energy loss, and comply with state rules.

Why Duct Leakage Test is Important In Long Beach, 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 forward important implications for home builders and HVAC contractors working in the state. A Duct Leakage Test along with a Blower Door Test is now required for any newly constructed or remodeled home as outlined in 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 boost your energy bills, overload your HVAC system, and send dust and insulation particles throughout your home. This makes duct leakage test vital for homes both old and newly built. Keep reading to find out why duct leakage test matters and what benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Long Beach, 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, aided by a precision pressure sensor, accurately measures airflow and reveals duct leaks without interrupting activities in your home. A duct leakage test — often referred to as a duct blaster test — identifies air loss in your ducts, allowing you to find the most effective ways to seal them.

duct leakage test is easy, clean, and unobtrusive for residents in the home. Most tests in Long Beach, 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 quantified in cubic feet per minute (CFM) for each 100 square feet of conditioned living space. Your technician uses a nanometer to capture subtle pressure changes, allowing accurate measurement of duct air leakage. Understanding this number allows you to pinpoint problem areas, assess needed improvements, and confirm whether your home satisfies local energy code requirements in Long Beach, NJ.

Cost of Excessive Duct Leakage

If you notice high energy costs, hot and cold spots, or ongoing HVAC repairs, duct leakage might be the underlying problem. According to ENERGY STAR, most households lose 20% to 30% of their heated or cooled air because of duct leaks. Outside hot or cold air leaking into your system puts extra strain on your HVAC unit, raising energy bills and decreasing comfort.

Overworked equipment also puts extra stress on the system, resulting in breakdowns and increased repair costs. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also introduce dust, mold spores, moisture, and additional contaminants into the duct system. This can make allergies more severe, reduce the quality of indoor air, and produce costly structural harm behind walls or ceilings as time progresses.

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 about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) allows technicians to seal leaks located inside inaccessible parts of ductwork. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked 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 excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with mastic and tape. Technicians use a duct leakage test before and after aerosol sealing to evaluate how much leakage has been lowered and verify the results.

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 heats and cools during seasonal changes, the ductwork expands and then contracts. Over time, this movement leads the joints to loosen, resulting in gaps and leaks — making a duct leakage test important for new and older homes in Long Beach, NJ.

Many energy auditors investigate duct leakage by running their hands over the ducts and using a small tool to determine the width of joint gaps. 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 measure under 4 CFM per 100 square feet with the air handler in place, or 3 CFM per 100 square feet if the air handler is not installed. For new construction, a duct leakage test must be successfully passed before the home can obtain an occupancy certificate.

If your home in Long Beach, 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 provide skilled recommendations to resolve leakage problems so you can reach a passing score, decrease energy costs, and improve home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by sealing all the ducts and registers with duct mask tape on both the supply and return side.

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.
