Why Duct Leakage Test is Important In Vineland 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 lead to several key implications for home builders and HVAC contractors working across the state. A Duct Leakage Test and a required Blower Door Test are now part of the compliance process for new construction and remodeled homes under 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 raise utility expenses, overburden your HVAC system, and push insulation material and dust through every area of your home. This makes duct leakage test vital for homes both old and newly built. Keep reading to find out why duct leakage test matters and what benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in Vineland city, NJ, the technician seals all supply and return registers other than the main return or the air handler. 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, combined with a precision pressure sensor, measures airflow and detects leaks in the duct system without causing any disturbance in your home. A duct leakage test — sometimes called a duct blaster test — detects air loss in the duct system, allowing you to apply the most suitable sealing solutions.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Vineland city, NJ are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

How to Measure Duct Leakage

Duct leakage is recorded in cubic feet per minute (CFM) per 100 square feet of the conditioned portion of the home. Your technician uses a nanometer to measure tiny pressure changes, revealing how much air is escaping through the ducts. Understanding this number allows you to pinpoint problem areas, assess needed improvements, and confirm whether your home satisfies local energy code requirements in Vineland city, NJ.

Cost of Excessive Duct Leakage

If you are experiencing high utility bills, uneven temperatures, or frequent HVAC repairs, duct leakage may be the cause. According to ENERGY STAR, leaking ducts cause the average home to lose 20%–30% of conditioned air. Air from outside—whether hot or cold—entering your system forces your HVAC to work harder, increasing utility bills and reducing indoor comfort.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps improve the long-term health of your HVAC system, boosting longevity and reducing ongoing maintenance requirements.

Duct leaks can also bring dust, mold spores, excess moisture, and other impurities into the duct system. This can worsen allergy reactions, negatively affect indoor air quality, and contribute to costly hidden structural damage over the years.

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 if the leaks are buried far inside your walls or ceilings?

Aerosol sealing technology (AeroSeal) is an effective solution for reaching hidden ductwork leaks. 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 releases a fine sealant mist that finds and fills small holes that traditional sealing methods cannot access.

This method seals small to medium leaks effectively. However, large gaps may still call for 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 usual area for air leakage in ducts is at the joints. Ductwork includes various metal pieces pressed together using tight fittings and metal bands, but these connections are hardly ever airtight.

As your HVAC system transitions between warm and cool air throughout the year, the ducts 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 Vineland city, NJ.

Many energy auditors check duct leakage by feeling around the ducts and using a small tool to test the width of gaps between joints. If your duct system has not been sealed with mastic and approved tape, there is a high chance that leakage is 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, you must pass a duct leakage test before the home can be approved for an occupancy certificate.

If your home in Vineland city, NJ doesn’t achieve a passing duct leakage score, you’re likely overspending on heating and cooling — and putting extended strain on your HVAC unit. Meeting the 3–4 CFM requirement is essential not only for following building code, but for keeping your home comfortable and energy-efficient.

Your technician will also offer professional recommendations to tackle leakage issues so you can secure a passing score, reduce utility costs, and strengthen home performance.

The Duct Leakage Test Steps Explained

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

After the registers are sealed, we set up the duct tester by attaching it to the unit or a main return.

The ducts are then lowered to a depressurized level of 25 Pascals. With the system at that pressure, the nanometer is used to read the duct leakage.
