Why Duct Leakage Test is Important In Point Pleasant, PA

Various states and municipalities have adopted the 2015 IECC, International Energy Conservation Code for single-family houses, along with the 2018 International Energy Conservation Code for multi-family units. 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 improperly sealed ducts account for a major portion of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can spike your energy costs, wear down your HVAC system, and spread dust and insulation throughout various parts of your home. This makes duct leakage test essential for both new and older homes. Continue reading to understand why duct leakage test matters and how it can benefit you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin the process of a duct leakage test in Point Pleasant, PA, your technician seals off all supply and return registers apart from the main return or air handler. A specially calibrated device known as a duct blaster is then attached to the duct opening. Its purpose is to depressurize the system so that escaping air can be detected.

The duct blaster works together with a precision pressure sensor to measure airflow and pinpoint leaks in the ductwork without disturbing your home. A duct leakage test — commonly called a duct blaster test — detects areas where your ducts lose air, helping you select the most efficient sealing solutions.

duct leakage test is straightforward, clean, and designed to be non-intrusive for residents. Most tests in Point Pleasant, PA are wrapped up in 30 to 60 minutes, with improvements that continue to boost comfort and efficiency for years.

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 read small pressure variations, helping determine the volume of air escaping through the ducts. Understanding this number lets you identify inefficiencies, weigh improvement options, and confirm your home’s compliance with local energy code requirements in Point Pleasant, PA.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, most households lose 20% to 30% of their heated or cooled air because of duct leaks. 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 contributes to repeated breakdowns and pricey repairs. Proper duct sealing helps preserve the long-term efficiency of your HVAC system, boosting its lifespan and cutting down on regular maintenance needs.

Duct leaks can also cause dust, mold spores, and excess moisture — along with other contaminants — to infiltrate the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC ensures that new homes are built with duct systems sealed entirely using efficient materials such as mastic, foil tape, and insulation. But what happens when air leaks are concealed deep in the walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To carry out this method, every vent is sealed except a single access point. The HVAC system is separated, and a machine is attached to the duct system. It pressurizes the ducts and injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method is extremely effective for sealing small to medium leaks. However, big gaps may still need manual sealing using mastic and tape. Technicians conduct duct leakage test before and after aerosol sealing to see how much the leakage dropped and ensure the treatment worked properly.

Common Areas of Duct Leakage

The most common place for ducts to leak air is through the joints. Ductwork is made of multiple metal pieces pressed together using tight fittings and metal bands, but these connections are rarely airtight.

As your HVAC system heats and cools throughout the year, the ducts expand and contract. Over time, this movement causes joints to lose their seal, creating gaps and leaks — making a duct leakage test valuable for any home in Point Pleasant, PA, whether new or old.

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 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 has to be under 4 CFM per 100 square feet when the air handler is in place, or 3 CFM per 100 square feet without it installed. For new construction, passing the duct leakage test is a necessary step before securing an occupancy certificate.

If your home in Point Pleasant, PA does not pass its duct leakage inspection, you’re likely paying higher heating and cooling bills — and stressing your HVAC system over time. Meeting the 3–4 CFM requirement is significant not only for meeting local code but also for maintaining optimal comfort and efficiency in your home.

Your technician will also provide expert insights into correcting leakage issues so you can meet passing standards, lower your utility expenses, and improve overall 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 connect the duct tester to the unit or to a main return.

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
