Verify your HVAC system’s efficiency and meet local requirements with reliable duct leakage test in Bass River township, NJ. Our certified technicians identify and quantify air leaks in duct systems so homeowners and builders can optimize comfort, reduce energy waste, and meet state-level requirements.

Why Duct Leakage Test is Important In Bass River township, NJ

In many jurisdictions, the 2015 IECC, International Energy Conservation Code governs single-family buildings, while the 2018 IECC applies to multi-family buildings. The change will result in several substantial implications for home builders and HVAC contractors engaged in work across the state. A Duct Leakage Test paired with a Blower Door Test is now expected for newly constructed and remodeled homes in accordance with the 2015 code requirements. Did you know that duct systems contribute heavily to 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 critical for both modern and older homes. Continue reading to explore why duct leakage test is important and how you benefit from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Bass River township, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. A specially calibrated duct blaster is then installed onto the opening. The fan lowers the pressure inside the ducts, helping reveal any leakage points.

The duct blaster functions with a precision pressure sensor to analyze airflow and spot leaks in the duct system without affecting your home’s comfort. A duct leakage test — sometimes labeled as a duct blaster test — finds where your ducts are leaking air so you can decide on the best sealing strategy.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Bass River township, NJ take between 30 and 60 minutes, and the improvements they deliver can elevate comfort and efficiency for years ahead.

How to Measure Duct Leakage

Duct leakage is defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number gives you insight into problem areas, helps you plan improvements, and ensures your home meets local energy code requirements in Bass River township, 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, homes with leaky ducts routinely lose 20% to 30% of conditioned air. If outdoor hot or cold air infiltrates your system, your HVAC struggles to maintain temperatures, raising energy costs and lowering comfort.

Overworked equipment also accelerates wear and tear, resulting in more breakdowns and costly repairs. Proper duct sealing helps maintain the long-term health of your HVAC system, extending its lifespan and reducing ongoing maintenance needs.

Duct leaks can also bring dust, mold spores, excess moisture, and other impurities into the duct system. This can irritate allergies, harm the air quality inside, and cause expensive hidden structural damage as time goes on.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires all newly constructed homes to have fully sealed ductwork with modern, energy-saving 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) is used to address openings concealed inside duct systems. 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 sends a fine aerosol sealant through the system, closing small gaps that normal sealing approaches can’t reach.

This method is effective for addressing small to medium leaks. However, larger holes still need manual sealing with mastic and tape. Technicians test the ducts for leakage before and after aerosol sealing to determine the reduction level and verify success.

Common Areas of Duct Leakage

The most typical location for air to escape from ducts is at the joints. Duct systems are built from multiple metal pieces pressed together with tight fittings and metal bands, but these joints are seldom completely airtight.

As your HVAC system warms and cools over the seasons, the ductwork expands and then contracts. Over time, this movement leads to joint loosening, generating gaps and leaks — a clear reason duct leakage test is recommended for new and older homes in Bass River township, NJ.

Many energy auditors locate duct leakage by touching the ductwork and using a small tool to measure the width of separation between joints. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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

To achieve a passing duct leakage result, your system has to measure below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler. For new construction, a passing duct leakage test is mandatory before a home can be granted an occupancy certificate.

If your home in Bass River township, NJ fails its duct leakage test, you are likely facing inflated heating and cooling costs — along with increased strain on your HVAC system. 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 skilled recommendations to resolve leakage problems so you can reach a passing score, decrease energy costs, and improve home performance.

The Duct Leakage Test Steps Explained

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

After the registers are sealed, we connect the duct tester to either the main HVAC unit or its primary return.

The ducts are then depressurized to 25 Pascals. At that point, the nanometer allows us to get an accurate duct leakage measurement.
