Duct Leakage Test in Wood-Ridge, NJ

Make sure your HVAC system performs at its best and satisfies local energy standards with certified duct leakage test in Wood-Ridge, NJ. Our certified technicians measure and identify ductwork air leaks, assisting homeowners and builders in boosting comfort, limiting energy waste, and maintaining state compliance.

Why Duct Leakage Test is Important In Wood-Ridge, NJ

Across the country, states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will set in motion important implications for home builders and HVAC contractors who operate in the state. A Duct Leakage Test paired with a Blower Door Test is now expected for newly constructed and remodeled homes in accordance with the 2015 code requirements. Did you know that ductwork often causes some of the highest levels of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout 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 begin a duct leakage test in Wood-Ridge, NJ, your technician will seal off all supply and return registers except for the main return or the air handler. A specially calibrated duct blaster fan is then connected to the opening. This fan depressurizes the ducts to help locate where air is escaping.

The duct blaster operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. A duct leakage test — sometimes called a duct blaster test — reveals where your ducts are losing air so you can determine the most effective sealing solutions.

duct leakage test is rapid, clean, and performed without inconvenience to residents. Most tests in Wood-Ridge, NJ are done in about 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency for many years.

How to Measure Duct Leakage

Duct leakage is calculated in cubic feet per minute (CFM) for every 100 square feet of conditioned space. Your technician uses a nanometer to measure tiny pressure differences, making it possible to determine how much air the ducts are losing. Understanding this number helps you pinpoint leakage points, think through potential improvements, and verify your home’s adherence to local energy code requirements in Wood-Ridge, 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 with leaky ducts routinely lose 20% to 30% of conditioned air. When outside hot or cold air seeps into your system, your HVAC must compensate, leading to higher energy costs and diminished comfort.

Overworked equipment also triggers more mechanical failures and costly service calls. 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 introduce dust, mold spores, moisture, and additional contaminants into the duct system. This can worsen allergy conditions, affect indoor air quality, and result in costly damage forming behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to use fully sealed duct systems crafted from up-to-date, efficient materials such as mastic, foil tape, and insulation. But what about leaks located deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) is designed to reach and seal hidden gaps throughout the duct system. To begin this method, every vent is sealed except for one access opening. The HVAC unit is isolated, and a machine is installed onto the duct system. It pressurizes the ducts and applies a fine aerosol sealant that fills tiny openings where standard 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 use before-and-after duct leakage tests to measure improvement and make sure the aerosol sealing process was successful.

Common Areas of Duct Leakage

The most common point where ducts leak air is along the joints. Ductwork is made from multiple metal pieces pressed together with tight fittings and metal bands, but these connections are rarely completely airtight.

As your HVAC system regulates temperatures through the seasons, the ducts expand when heated and contract when cooled. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Wood-Ridge, NJ, new or older, benefit from duct leakage test.

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 isn’t sealed with mastic and approved tape, there’s a good chance that leaks are occurring.

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, homes are required to pass a duct leakage test before an occupancy certificate can be issued.

If your home in Wood-Ridge, NJ cannot achieve a passing duct leakage score, you are likely wasting money on heating and cooling — and increasing wear on your HVAC system over time. Meeting the 3–4 CFM requirement is important not only for the inspector, but also for maximizing energy efficiency and comfort in your home.

Your technician will also give expert suggestions on correcting leakage issues, allowing you to pass the test, lower utility expenses, and improve your home’s overall efficiency.

The Duct Leakage Test Steps Explained

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

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

The ducts are then brought down to 25 Pascals of pressure. With the ducts depressurized, the nanometer can be used to read the leakage level.
