Why Duct Leakage Test is Important In Asbury Park, NJ

In most states and municipalities, the 2015 IECC, International Energy Conservation Code is required for single-family homes, while the 2018 International Energy Conservation Code is required for multi-family homes. The change will create considerable implications for home builders and HVAC contractors carrying out projects in the state. A Duct Leakage Test as well as a Blower Door Test in newly constructed or remodeled homes is now required in accordance with the 2015 regulations. Did you know that leaking ducts are a widespread cause of air loss in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can cause your energy bills to rise, strain your HVAC system, and move dust and insulation around your living spaces. This makes duct leakage test a key step for new and older homes alike. Read ahead to see why duct leakage test is needed and what advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin performing a duct leakage test in Asbury Park, NJ, your technician closes off all supply and return registers except the main return or air handler system. 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 joins forces with a precision pressure sensor to monitor airflow and pinpoint leak points in the ducts without disturbing your home. A duct leakage test — also called a duct blaster test — locates the points where duct air escapes, helping you implement the right sealing solution.

duct leakage test is prompt, clean, and does not interrupt residents’ activities. Most tests in Asbury Park, 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 rated in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned zone. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from 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 Asbury Park, NJ.

Cost of Excessive Duct Leakage

If you’re encountering increased energy bills, temperature inconsistencies, or constant HVAC repairs, duct leakage could be the source. According to ENERGY STAR, the average home loses 20% to 30% of conditioned air through 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 accelerates wear and tear, resulting in more breakdowns and costly repairs. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. 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 enforces that new homes incorporate fully sealed ducts made with modern, energy-efficient materials including mastic, foil tape, and insulation. But what do you do about leaks that sit deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To set up this method, all vents are sealed off except for a single access point. The HVAC system is isolated, and a machine is fitted to the duct system. It pressurizes the ducts and applies a fine aerosol sealant that fills tiny openings where standard sealing cannot reach.

This method is great for handling small to medium leaks. However, larger holes often require manual sealing with 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 during seasonal changes, the ductwork expands and then contracts. Over time, this movement makes joints shift and loosen, forming gaps and leaks — which is why a duct leakage test is advised for homes old and new in Asbury Park, NJ.

Many energy auditors look for leaks by feeling the ducts and using a small tool to evaluate how wide the gaps at the joints are. If your duct system lacks sealing with mastic and approved tape, there is a strong chance that leakage is present.

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

To achieve a passing duct leakage result, your system needs to measure under 4 CFM per 100 square feet when the air handler is included, or 3 CFM per 100 square feet when it is not. For new construction, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Asbury Park, NJ doesn’t receive a passing duct leakage result, you are likely overpaying for heating and cooling — and putting significant long-term strain on your HVAC setup. 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 share expert recommendations for fixing leakage problems, helping you achieve a passing score, save on utilities, and improve 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 mount the duct tester onto the unit or onto a main return.

The ducts are then pulled down to 25 Pascals of depressurization. With the ducts in this state, we take a leakage reading using the nanometer.
