Duct Leakage Test in Atlantic City, NJ

Make sure your HVAC system performs at its best and satisfies local energy standards with certified duct leakage test in Atlantic City, NJ. Our certified technicians find and measure ductwork air leaks, allowing homeowners and builders to improve indoor comfort, reduce energy waste, and satisfy state standards.

Why Duct Leakage Test is Important In Atlantic City, 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 result in significant implications for home builders and HVAC contractors doing business 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 ducts often contribute significantly to air leakage problems in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. 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 the process of a duct leakage test in Atlantic City, NJ, your technician seals off all supply and return registers apart from the main return or air handler. A duct blaster — a precision-calibrated fan — is then fitted to the duct opening. By depressurizing the system, it makes all air leaks much easier to detect.

The duct blaster operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. A duct leakage test — sometimes identified as a duct blaster test — shows where your ducts lose air, helping you plan the right sealing approach.

duct leakage test is easy, clean, and unobtrusive for residents in the home. Most tests in Atlantic City, NJ take 30 to 60 minutes to complete, and the benefits to comfort and efficiency can endure for years.

How to Measure Duct Leakage

Duct leakage is assessed using cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number allows you to identify concerns, evaluate upgrade opportunities, and determine whether your home fulfills local energy code requirements in Atlantic City, NJ.

Cost of Excessive Duct Leakage

If your home suffers from costly utility bills, uneven comfort levels, or persistent HVAC repairs, duct leakage may be contributing. According to ENERGY STAR, duct leakage causes homeowners to lose 20%–30% of their conditioned air on average. Hot or cold air entering from outside increases the workload on your HVAC system, leading to higher energy bills and a drop in comfort.

Overworked equipment also puts extra stress on the system, resulting in breakdowns and increased repair costs. Proper duct sealing helps uphold the long-term performance of your HVAC system, stretching its lifespan and decreasing routine maintenance demands.

Duct leaks can also bring dust, mold spores, excess moisture, and other impurities 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 specifies that newly constructed homes must use fully sealed duct systems with modern, efficient materials such as mastic, foil tape, and insulation. But what do you do about leaks that sit deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. 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 releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method is effective at treating small to medium leaks. However, big openings may still need to be addressed with manual mastic-and-tape sealing. Technicians conduct a duct leakage test before and after aerosol sealing to measure how much the leakage has been reduced and ensure the treatment is successful.

Common Areas of Duct Leakage

The most common area where ducts leak air is around the joints. Ductwork uses several metal parts pressed together with tight fittings and metal bands, though these points are rarely airtight.

As your HVAC system adjusts temperatures throughout the year, the ducts go through expansion and contraction. 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 Atlantic City, NJ.

Many energy auditors assess duct leakage by touching the ductwork and using a small tool to check the width of gaps where joints connect. If your duct system is unsealed with mastic and approved tape, air leakage is almost certainly occurring.

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, passing a duct leakage test is required before a home can receive an occupancy certificate.

If your home in Atlantic City, NJ fails duct leakage test, you are probably spending unnecessarily on heating and cooling — and placing ongoing stress on your HVAC equipment. Meeting the 3–4 CFM requirement is crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

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 with sealing all ducts and registers using duct mask tape on both 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 pulled down to 25 Pascals of depressurization. With the ducts in this state, we take a leakage reading using the nanometer.
