Duct Leakage Test in Lincoln Park, NJ

Confirm your HVAC system’s efficiency and meet local inspection standards with professional duct leakage test in Lincoln Park, NJ. Our certified technicians trace and measure duct leaks, supporting homeowners and builders in enhancing comfort, lowering energy waste, and staying compliant with state codes.

Why Duct Leakage Test is Important In Lincoln Park, NJ

Across many states and municipalities, the 2015 IECC, International Energy Conservation Code applies to single-family homes, while the 2018 International Energy Conservation Code governs multi-family buildings. The change will create considerable implications for home builders and HVAC contractors carrying out projects 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 a significant source of air leakage in residential properties across Pennsylvania, New Jersey, and Delaware? Leaked air can increase your energy costs, overwork your HVAC system, and distribute insulation particles and dust around your home. This makes duct leakage test indispensable no matter the age of your home. Continue reading to understand why duct leakage test is important and the benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start the duct testing process in Lincoln Park, NJ, the technician seals all supply and return registers except for the main return or the air handler. A calibrated duct blaster is then mounted to the opening. By depressurizing the duct system, it creates ideal conditions for detecting air leaks.

The duct blaster operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. A duct leakage test — often known as a duct blaster test — exposes duct air loss, allowing you to apply the most effective sealing techniques.

duct leakage test is quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Lincoln 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 evaluated in cubic feet per minute (CFM) per 100 square feet of conditioned space inside the home. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number enables you to recognize problem areas, consider efficiency improvements, and verify that your home meets local energy code requirements in Lincoln Park, NJ.

Cost of Excessive Duct Leakage

If you’re struggling with expensive utility bills, inconsistent indoor temperatures, or continual HVAC problems, duct leakage might be the culprit. According to ENERGY STAR, most households lose 20% to 30% of their heated or cooled air because of duct leaks. Hot or cold outside air creeping into your system forces the HVAC to work inefficiently, increasing energy spending and reducing comfort.

Overworked equipment also accelerates wear and tear, resulting in more breakdowns and costly repairs. Proper duct sealing helps improve the long-term health of your HVAC system, boosting longevity and reducing ongoing maintenance requirements.

Duct leaks can also allow dust, mold spores, excess moisture, and other contaminants into the duct system. This can make allergies worse, impact indoor air quality, and result in costly structural damage behind walls or ceilings as time passes.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates that new homes include fully sealed duct systems built with energy-efficient materials like mastic, foil tape, and proper insulation. But what if the leaks are buried far inside your walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To start this method, all vents are blocked except for one access location. The HVAC system is isolated, and a machine is attached 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 is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians perform a duct leakage test both before and after aerosol sealing to determine how much leakage has decreased and confirm the treatment worked.

Common Areas of Duct Leakage

The most usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system shifts between hot and cold cycles all year long, the ductwork expands and contracts. Over time, this movement loosens the joints, causing gaps and leaks — which is why both new and older homes in Lincoln Park, NJ should consider a duct leakage test.

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 was never sealed using mastic and approved tape, there is a high probability that air leakage is present.

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, you must pass a duct leakage test before the home can be approved for an occupancy certificate.

If your home in Lincoln Park, 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 crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

Your technician will also offer specialized recommendations to repair leakage issues so you can meet passing requirements, reduce utility bills, and improve your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by closing off every duct and register with duct mask tape across 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 25 Pascals. With this pressure applied, we use the nanometer to measure how much leakage is present.
