Guarantee your HVAC system runs efficiently and adheres to local requirements with quality duct leakage test in Egg Harbor city, NJ. Our certified technicians identify and quantify air leaks in duct systems so homeowners and builders can optimize comfort, reduce energy waste, and meet state-level requirements.

Why Duct Leakage Test is Important In Egg Harbor city, NJ

States and municipalities now follow the 2015 IECC, International Energy Conservation Code for single-family residences, as well as the 2018 International Energy Conservation Code for multi-family structures. The change will create considerable implications for home builders and HVAC contractors carrying out projects in 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 responsible for a large share of air leakage issues in homes in 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 begin a duct leakage test in Egg Harbor city, NJ, your technician will seal off all supply and return registers except for the main return or the air handler. A calibrated duct blaster is then mounted to the opening. By depressurizing the duct system, it creates ideal conditions for detecting air leaks.

The duct blaster uses a precision pressure sensor to monitor airflow and pinpoint leaks throughout the ductwork without interrupting your home environment. A duct leakage test — often known as a duct blaster test — exposes duct air loss, allowing you to apply the most effective sealing techniques.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Egg Harbor city, NJ finish in 30 to 60 minutes, and the upgrades continue benefiting your home’s comfort and efficiency long after.

How to Measure Duct Leakage

Duct leakage is reported in cubic feet per minute (CFM) per 100 square feet of conditioned home area. 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 Egg Harbor city, 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, homes with leaky ducts routinely lose 20% to 30% of conditioned air. When hot or cold outside air enters your system, your HVAC has to work harder, increasing energy costs and lowering overall comfort.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. Proper duct sealing helps maintain the long-term health of your HVAC system, extending its lifespan and reducing ongoing maintenance needs.

Duct leaks can also draw in dust, mold spores, unwanted moisture, and other harmful contaminants. This can make allergies worse, impact indoor air quality, and result in costly structural damage behind walls or ceilings as time passes.

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 happens when leaks are trapped deep inside wall or ceiling cavities?

Aerosol sealing technology (AeroSeal) is designed to reach and seal hidden gaps throughout the duct system. To execute this method, all vents are sealed shut except a single access point. The HVAC system is isolated, and a machine is attached to the duct network. It pressurizes the ducts and sprays a fine mist of sealant that fills tiny leaks and holes beyond the reach of conventional sealing.

This method excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with mastic and tape. Technicians carry out leakage testing prior to and after aerosol sealing to observe the reduction and ensure treatment success.

Common Areas of Duct Leakage

The most usual area for air leakage in ducts is at the joints. Ductwork includes various metal pieces pressed together using tight fittings and metal bands, but these connections are hardly ever airtight.

As your HVAC system warms and cools over the seasons, the ductwork expands and then contracts. Over time, this movement gradually loosens the joints, creating leaks and gaps — highlighting the importance of duct leakage test in both new and older homes in Egg Harbor city, NJ.

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 was never sealed using mastic and approved tape, there is a high probability that air leakage is present.

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, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Egg Harbor city, NJ doesn’t pass its duct leakage evaluation, you’re likely paying more for temperature control — and contributing to long-term HVAC strain. Meeting the 3–4 CFM requirement is required not only for code approval but for keeping your home efficient and comfortable.

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 sealing all the ducts and registers with duct mask tape on both the supply and return side.

After the registers are sealed, we secure the duct tester to the HVAC unit or to a main return.

The ducts are then placed under 25 Pascals of negative pressure. With the ducts depressurized, we obtain the leakage reading using the nanometer.
