Verify your HVAC system’s efficiency and meet local requirements with reliable duct leakage test in Brigantine city, NJ. Our certified technicians detect and measure air leakage in ductwork, supporting homeowners and builders in improving comfort, minimizing wasted energy, and meeting state requirements.

Why Duct Leakage Test is Important In Brigantine city, NJ

States and municipalities have standardized around the 2015 IECC, International Energy Conservation Code for single-family builds and the 2018 International Energy Conservation Code for multi-family builds. The change will bring forward important implications for home builders and HVAC contractors working in 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 are among the biggest contributors to air leakage in homes all across Pennsylvania, New Jersey, and Delaware? Leaked air can elevate your energy bills, make your HVAC system work harder, and distribute insulation fibers and dust through your home. This makes duct leakage test a crucial step for maintaining comfort in new and old homes alike. Continue reading to learn why duct leakage test is valuable and how it benefits you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To commence a duct leakage test in Brigantine city, NJ, your technician will seal every supply and return register except the primary return or air handler. A calibrated duct blaster fan is then mounted to the opening. This fan creates negative pressure inside the ducts, making air leakage locations easier to find.

The duct blaster, combined with a precision pressure sensor, measures airflow and detects leaks in the duct system without causing any disturbance 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 straightforward, clean, and designed to be non-intrusive for residents. Most tests in Brigantine city, 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 tracked in cubic feet per minute (CFM) per 100 square feet of conditioned living area. Your technician uses a nanometer to capture subtle pressure changes, allowing accurate measurement of duct air leakage. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Brigantine city, 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, the majority of homes lose 20% to 30% of conditioned air through duct leaks. Hot or cold outside air entering your system forces your HVAC system to work harder, driving up energy costs and reducing comfort.

Overworked equipment also produces more frequent issues that require costly repairs. Proper duct sealing helps promote the long-term integrity of your HVAC system, extending its lifespan and limiting continued maintenance needs.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. This can worsen allergies, reduce indoor air quality, and even cause expensive structural damage behind walls or ceilings over time.

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 should you do when leaks are located deep within your walls or ceilings?

Aerosol sealing technology (AeroSeal) can access interior duct leaks that are difficult to reach manually. To initiate this method, technicians seal every vent except one access point. The HVAC system is isolated, and a machine is connected to the ductwork. It pressurizes the ducts and injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method works very well for small to medium leaks. However, larger openings may still need to 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 frequent area where ducts lose air is at the joints. Ductwork consists of several metal sections pressed together with tight fittings and metal bands, yet these connections are almost never fully airtight.

As your HVAC system delivers heat and cooling across different seasons, the ducts constantly expand and contract. 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 Brigantine city, NJ.

Many energy auditors assess duct leakage by touching the ductwork and using a small tool to check the width of gaps where joints connect. If your duct system lacks proper sealing with mastic and approved tape, there is a high chance that leakage is taking place.

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

To achieve a passing duct leakage result, your system needs to be under 4 CFM per 100 square feet when the air handler is installed, or 3 CFM per 100 square feet when it isn’t. For new construction, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Brigantine city, NJ doesn’t pass a duct leakage test, chances are you’re paying more for heating and cooling — and adding long-term stress to your HVAC equipment. Meeting the 3–4 CFM requirement is fundamental not only for code adherence but for boosting your home’s long-term efficiency and comfort.

Your technician will also share expert recommendations for fixing leakage problems, helping you achieve a passing score, save on utilities, and improve home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with duct mask tape being placed on all ducts and registers on both the supply and return sides.

After the registers are sealed we attached the duct tester to either the unit itself or a main return.

The ducts are then depressurized to 25 Pascals. With the ducts at this pressure, we can use the nanometer to measure the duct leakage.
