Why Duct Leakage Test is Important In Palisades Park, NJ

States and municipalities have adopted 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 in addition to a Blower Door Test is now required for new construction and remodeled homes under the 2015 rules. Did you know that duct leakage is one of the most common issues affecting homes in Pennsylvania, New Jersey, and Delaware? Leaked air can escalate your energy costs, force your HVAC system to work harder, and move insulation and dust throughout your house. This makes duct leakage test necessary for homes of any age. Keep reading to discover why duct leakage test is so important and the advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Palisades Park, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. 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 collaborates with a precision pressure sensor to evaluate airflow and locate leaks throughout the ductwork without disturbing your household. A duct leakage test — sometimes referred to as a duct blaster test — uncovers air leaks in your ductwork so you can determine the ideal sealing approach.

duct leakage test is quick, clean, and non-intrusive for residents. Most tests in Palisades Park, NJ require only 30 to 60 minutes, yet the upgrades can improve your home’s comfort and efficiency well into the future.

How to Measure Duct Leakage

Duct leakage is measured using cubic feet per minute (CFM) per 100 square feet of conditioned floor area. Your technician uses a nanometer to identify pressure differences, which provide a clear picture of how much air is leaking from the ductwork. Understanding this number helps you recognize where issues exist, plan meaningful improvements, and check your home against local energy code requirements in Palisades Park, NJ.

Cost of Excessive Duct Leakage

If you notice high energy costs, hot and cold spots, or ongoing HVAC repairs, duct leakage might be the underlying problem. According to ENERGY STAR, most homes lose 20% to 30% of their conditioned air through leaking ductwork. Hot or cold outside air entering your system forces your HVAC system to work harder, driving up energy costs and reducing comfort.

Overworked equipment also produces more frequent issues that require costly repairs. Proper duct sealing helps improve the long-term health of your HVAC system, boosting longevity and reducing ongoing maintenance requirements.

Duct leaks can also allow dust, mold spores, excess moisture, and other contaminants into the duct system. This can trigger more severe allergies, diminish indoor air quality, and create expensive structural problems behind walls or ceilings over time.

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 if the leaks you’re dealing with are deep inside the walls or ceilings?

Aerosol sealing technology (AeroSeal) makes it possible to seal leaks found deep within the ductwork. To apply this method, every vent is sealed aside from one access point. The HVAC system is isolated, and a machine is connected to the ducts. It pressurizes the ducts and pushes a fine aerosol sealant through them, sealing small holes that ordinary sealing methods can’t reach.

This method is extremely effective for sealing small to medium leaks. However, big gaps may still need manual sealing using 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 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 weakens the joints, creating gaps and leaks — a key reason duct leakage test is recommended for new and older homes in Palisades Park, NJ.

Many energy auditors examine duct leakage by touching the ducts and using a small tool to measure the gap width between joints. If your duct system lacks proper sealing with mastic and approved tape, there is a high chance that leakage is taking place.

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, an occupancy certificate cannot be issued unless the home passes a duct leakage test.

If your home in Palisades Park, NJ doesn’t pass a duct leakage test, chances are you’re paying more for heating and cooling — and adding long-term stress to your HVAC equipment. Meeting the 3–4 CFM requirement is needed not only for passing inspections, but also for improving home comfort and energy efficiency.

Your technician will also provide expert strategies to address leakage concerns, helping you achieve a passing score, bring down utility bills, and boost home efficiency.

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 attached the duct tester to either the unit itself or a main return.

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