Why Duct Leakage Test is Important In Brigantine, NJ

States and municipalities have put in place the 2015 IECC, International Energy Conservation Code for single-family projects and the 2018 International Energy Conservation Code for multi-family projects. The change will bring notable implications for home builders and HVAC contractors working throughout the state. A Duct Leakage Test alongside a Blower Door Test must now be completed in newly constructed or remodeled homes to meet the 2015 regulatory standards. Did you know that ducts are a leading factor in home air leakage across Pennsylvania, New Jersey, and Delaware? Leaked air can raise utility expenses, overburden your HVAC system, and push insulation material and dust through every area of your home. This makes duct leakage test crucial for new and old homes alike. Keep reading to learn why duct leakage test is important and how you can benefit from them.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin a duct leakage test in Brigantine, NJ, your technician will seal off all supply and return registers except for the main return or the air handler. A specially calibrated fan known as a duct blaster is then put in place at the opening. It depressurizes the ductwork so escaping air can be accurately identified.

The duct blaster system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. A duct leakage test — also known as a duct blaster test — pinpoints where air is escaping from your ducts, helping you choose the best sealing methods.

duct leakage test is fast, debris-free, and completely resident-friendly. Most tests in Brigantine, NJ are completed in just 30 to 60 minutes, while the benefits to comfort and efficiency can last long-term.

How to Measure Duct Leakage

Duct leakage is evaluated in cubic feet per minute (CFM) per 100 square feet of conditioned space inside the home. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Brigantine, NJ.

Cost of Excessive Duct Leakage

If your home suffers from costly utility bills, uneven comfort levels, or persistent HVAC repairs, duct leakage may be contributing. According to ENERGY STAR, the typical home loses between 20% and 30% of its conditioned air due to duct leaks. Outside air that’s too hot or too cold entering your system strains your HVAC, resulting in higher energy consumption and less comfort.

Overworked equipment also increases the likelihood of breakdowns and drives up repair costs. Proper duct sealing helps uphold the long-term performance of your HVAC system, stretching its lifespan and decreasing routine maintenance demands.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. This can intensify allergy symptoms, harm indoor air quality, and cause long-term structural damage behind walls or ceilings.

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 located deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) provides a way to seal concealed openings inside the duct system. To set up this method, all vents are sealed off except for a single access point. The HVAC system is isolated, and a machine is fitted to the duct system. It pressurizes the ducts and distributes an ultra-fine aerosol sealant to fill small gaps and holes that manual sealing methods can’t access.

This method is ideal for small to medium leaks. However, any large openings will still need manual sealing with mastic and tape. Technicians run a duct leakage test before and after aerosol sealing to quantify the reduction in leakage and verify the success of the process.

Common Areas of Duct Leakage

The most typical place for ducts to lose air is at the joints. Ductwork consists of different metal sections pressed together with tight fittings and metal bands, yet these joints are not usually airtight.

As your HVAC system heats and cools during seasonal changes, the ductwork expands and then contracts. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Brigantine, NJ, new or older, benefit from duct leakage test.

Many energy auditors detect duct leakage by physically checking the ducts and using a small tool to assess the width of joint gaps. If your duct system lacks sealing with mastic and approved tape, there is a strong chance that leakage is present.

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

To achieve a passing duct leakage result, your system should stay under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it. For new construction, a duct leakage test must be successfully passed before the home can obtain an occupancy certificate.

If your home in Brigantine, NJ fails duct leakage test, you are probably spending unnecessarily on heating and cooling — and placing ongoing stress on your HVAC equipment. Meeting the 3–4 CFM requirement is key not only for staying code-compliant but for maintaining energy efficiency and consistent comfort in your home.

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 applying duct mask tape to seal every duct and register on both 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 a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
