Make sure your HVAC system is performing efficiently and meeting local standards with thorough duct leakage test in Estell Manor, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Estell Manor, 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 several important implications for home builders and HVAC contractors operating within the state. A Duct Leakage Test in addition to a Blower Door Test is now required for new construction and remodeled homes under the 2015 rules. Did you know that ducts are a significant source of air leakage in residential properties 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 important for all types of homes, whether new or old. Continue reading to learn why duct leakage test is essential and how you can benefit.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To set up a duct leakage test in Estell Manor, NJ, the technician begins by sealing all supply and return registers, leaving only the air handler or main return open. A specially calibrated fan called a duct blaster is then connected to the opening. This fan depressurizes the duct system, making it easier to pinpoint exactly where air is leaking.

The duct blaster and its precision pressure sensor work together to measure airflow and detect duct leaks without causing any disruption in your home. A duct leakage test — often described as a duct blaster test — identifies leaking areas in your ducts so you can determine the most efficient sealing fix.

duct leakage test is efficient, mess-free, and completely non-intrusive for residents. Most tests in Estell Manor, 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 tracked in cubic feet per minute (CFM) per 100 square feet of conditioned living area. Your technician uses a nanometer to evaluate small pressure shifts that signal 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 Estell Manor, NJ.

Cost of Excessive Duct Leakage

If you’re dealing with rising utility bills, inconsistent room temperatures, or repeated HVAC issues, duct leakage could be the reason. According to ENERGY STAR, an average home’s ductwork loses 20% to 30% of conditioned air through leaks. When outdoor temperatures enter your system, the HVAC must work harder to compensate, resulting in higher energy costs and reduced comfort.

Overworked equipment also puts extra stress on the system, resulting in breakdowns and increased repair costs. Proper duct sealing helps strengthen the long-term function of your HVAC system, improving its lifespan and reducing ongoing maintenance costs.

Duct leaks can also let in dust, mold spores, added moisture, and other harmful contaminants. This can negatively influence allergies, weaken indoor air quality, and lead to expensive long-term damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires newly built homes to install fully sealed duct systems using advanced materials like mastic, foil tape, and quality insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and distributes a fine aerosolized sealant that seals small openings traditional methods cannot reach.

This method is ideal for small to medium leaks. However, any large openings will still need manual sealing with 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 usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system operates in both heating and cooling modes year-round, the ducts continuously expand and contract. 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 Estell Manor, NJ.

Many energy auditors look for duct leakage by running their hands along the ducts and using a small tool to measure the width of gaps at the joints. If your duct system does not include sealing with mastic and approved tape, leakage is highly likely.

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

To achieve a passing duct leakage result, your system must remain below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet if the air handler is missing. For new construction, a passing duct leakage test is essential before the home can qualify for an occupancy certificate.

If your home in Estell Manor, NJ fails its duct leakage test, you are likely facing inflated heating and cooling costs — along with increased strain on your HVAC system. 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 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 technicians sealing all ducts and registers using duct mask tape on the supply and return sides.

After the registers are sealed, we install the duct tester on the unit or on a main return.

The ducts are then depressurized to 25 Pascals. With this pressure applied, we use the nanometer to measure how much leakage is present.
