Why Duct Leakage Test is Important In Bordentown township, NJ

Many states and municipalities oversee single-family buildings under the 2015 IECC, International Energy Conservation Code and multi-family buildings under the 2018 International Energy Conservation Code. The change will set in motion important implications for home builders and HVAC contractors who operate in the state. A Duct Leakage Test and a Blower Door Test are now mandatory for newly built or renovated 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 cause higher energy expenses, burden your HVAC system, and push dust and insulation into different areas of your home. This makes duct leakage test beneficial for all homes, new or old. Keep reading to find out why duct leakage test is essential and how it can improve your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Bordentown township, NJ, your technician first seals all supply and return registers except the main return or 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 system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. A duct leakage test — frequently called a duct blaster test — reveals air escape points in your ducts, guiding you toward the best sealing options.

duct leakage test is swift, clean, and carried out with no disturbance to residents. Most tests in Bordentown township, NJ finish in 30 to 60 minutes, and the upgrades continue benefiting your home’s comfort and efficiency long after.

How to Measure Duct Leakage

Duct leakage is measured in cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a nanometer to evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number helps you uncover weak points, analyze opportunities for upgrades, and check whether your home follows local energy code requirements in Bordentown township, NJ.

Cost of Excessive Duct Leakage

If you observe rising utility costs, temperature swings in different rooms, or regular HVAC breakdowns, duct leakage may be involved. According to ENERGY STAR, a large portion of homes lose between 20% and 30% of conditioned air due to leaky ducts. Outside hot or cold air leaking into your system puts extra strain on your HVAC unit, raising energy bills and decreasing comfort.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also allow dust, mold spores, excess moisture, and other contaminants into the duct system. This can escalate allergies, lower the overall air quality indoors, and lead to costly damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to have fully sealed duct systems using modern, energy-efficient materials such as mastic, foil tape, and insulation. But what if the leaks you’re dealing with are deep inside the walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To perform this method, all vents are sealed off except for one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and releases a fine sealant mist that finds and fills small holes that traditional sealing methods cannot access.

This method is effective for addressing small to medium leaks. However, larger holes still need manual sealing with mastic and tape. Technicians complete a duct leakage test before and after aerosol sealing to track leakage reduction and confirm the treatment’s success.

Common Areas of Duct Leakage

The most frequent area where ducts lose air is at the joints. Ductwork consists of several metal sections pressed together with tight fittings and metal bands, yet these connections are almost never fully airtight.

As your HVAC system moves through annual heating and cooling cycles, the ductwork expands and then contracts. Over time, this movement causes the joints to loosen, creating gaps and leaks — which is why a duct leakage test is recommended for both new and older homes in Bordentown township, 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 was not sealed with mastic and approved tape, there’s a high likelihood that air is leaking.

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

To achieve a passing duct leakage result, your system must come in under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is removed. For new construction, homes are required to pass a duct leakage test before an occupancy certificate can be issued.

If your home in Bordentown township, NJ does not meet the duct leakage requirement, you’re likely paying elevated heating and cooling costs — and overburdening your HVAC system. 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 provide expert recommendations on how to address leakage issues so you can achieve a passing score, lower your utility bills, and improve your home’s overall performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by covering all ducts and registers with duct mask tape on both the supply and return sides.

After the registers are sealed, we attach our duct tester to the system’s unit or to the main return.

The ducts are then depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
