Why Duct Leakage Test is Important In Chatham borough, NJ

In many jurisdictions, the 2015 IECC, International Energy Conservation Code governs single-family buildings, while the 2018 IECC applies to multi-family buildings. The change will lead to several key implications for home builders and HVAC contractors working across the state. A Duct Leakage Test and a required Blower Door Test are now part of the compliance process for new construction and remodeled homes under the 2015 regulations. Did you know that ducts are one of the primary sources of air leakage in homes throughout 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 highly important for homes of any age. Read on to learn why duct leakage test matters and the benefits you can gain.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To kick off a duct leakage test in Chatham borough, NJ, your technician will block all supply and return registers while keeping the main return or air handler accessible. A duct blaster fan, carefully calibrated for accuracy, is then attached to the duct opening. It depressurizes the ductwork, allowing leaks to become more noticeable.

The duct blaster collaborates with a precision pressure sensor to evaluate airflow and locate leaks throughout the ductwork without disturbing your household. 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 fast, clean, and comfortable for residents throughout the process. Most tests in Chatham borough, NJ 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 defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to read small pressure variations, helping determine the volume of air escaping through the ducts. Understanding this number gives you insight into problem areas, helps you plan improvements, and ensures your home meets local energy code requirements in Chatham borough, 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, most households lose 20% to 30% of their heated or cooled air because of 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 heightens the chance of system failures and expensive repairs. Proper duct sealing helps protect the long-term performance of your HVAC system, increasing its lifespan and lowering future maintenance requirements.

Duct leaks can also pull in dust, mold spores, moisture, and numerous contaminants into the duct system. This can increase allergy discomfort, degrade indoor air quality, and eventually cause expensive structural issues behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC specifies that newly constructed homes must use fully sealed duct systems with modern, efficient materials such as mastic, foil tape, and insulation. But what if those leaks are tucked away behind walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To start this method, all vents are blocked except for one access location. The HVAC system is isolated, and a machine is attached to the ducts. It pressurizes the ducts and releases a delicate aerosol sealant that settles into small gaps and holes traditional techniques can’t access.

This method works efficiently for small to medium leaks. However, larger gaps usually require manual sealing using 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 frequent point of air leakage in ductwork is the joints. Multiple metal parts are pressed together using tight fittings and metal bands, although these junctions are seldom airtight.

As your HVAC system shifts between hot and cold cycles all year long, the ductwork expands and contracts. Over time, this movement allows the joints to loosen, producing gaps and leaks — which is why a duct leakage test is suggested for homes of all ages in Chatham borough, NJ.

Many energy auditors check for leaks by feeling along the ductwork and using a small tool to gauge the size of gaps between joints. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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

To achieve a passing duct leakage result, your system should measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler installed. For new construction, a passing duct leakage test is mandatory before a home can be granted an occupancy certificate.

If your home in Chatham borough, NJ cannot pass a duct leakage test, you are likely wasting money on heating and cooling — and causing long-term wear on your HVAC system. Meeting the 3–4 CFM requirement is vital not only for satisfying code rules but also for preserving your home’s comfort and energy performance.

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 with sealing each duct and register using duct mask tape on the supply and return sides.

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

The ducts are then set to a depressurized pressure of 25 Pascals. Once there, we use the nanometer to capture the leakage reading.
