Duct Leakage Test in Kinnelon, NJ

Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in Kinnelon, NJ. Our certified technicians pinpoint and measure ductwork air leaks, helping homeowners and builders boost comfort, cut energy waste, and meet state compliance standards.

Why Duct Leakage Test is Important In Kinnelon, NJ

States and municipalities are using the 2015 IECC, International Energy Conservation Code for single-family construction and the 2018 International Energy Conservation Code for multi-family construction. The change will present notable implications for home builders and HVAC contractors active throughout 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 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 essential for both new and older homes. Continue reading to understand why duct leakage test matters and how it can benefit you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To prepare for a duct leakage test in Kinnelon, NJ, the technician seals every supply and return register, leaving only the main return or air handler unsealed. A duct blaster fan, carefully calibrated for accuracy, is then attached to the duct opening. It depressurizes the ductwork, allowing leaks to become more noticeable.

The duct blaster system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. A duct leakage test — often described as a duct blaster test — identifies leaking areas in your ducts so you can determine the most efficient sealing fix.

duct leakage test is fast, clean, and comfortable for residents throughout the process. Most tests in Kinnelon, NJ are wrapped up in 30 to 60 minutes, with improvements that continue to boost comfort and efficiency for years.

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 relies on a nanometer to read slight pressure variations that show the amount of air leaking through the duct system. Understanding this number helps you pinpoint leakage points, think through potential improvements, and verify your home’s adherence to local energy code requirements in Kinnelon, NJ.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also produces more frequent issues that require costly repairs. Proper duct sealing helps sustain your HVAC system’s long-term condition, increasing its operational lifespan and decreasing maintenance requirements.

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter the duct system. This can amplify allergy problems, impact air quality indoors, and slowly create costly structural 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 happens when leaks are trapped deep inside wall or ceiling cavities?

Aerosol sealing technology (AeroSeal) enables effective sealing of leaks hidden inside ducts. To use this method, technicians seal all vents except one access point. The HVAC system is isolated, and a machine is hooked up to the duct system. It pressurizes the ducts and sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method is extremely effective for sealing small to medium leaks. However, big gaps may still need manual sealing using mastic and tape. Technicians run leakage tests both before and after aerosol sealing to gauge how much air loss decreased and confirm proper results.

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 heats and cools 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 Kinnelon, 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 should stay under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it. For new construction, a duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Kinnelon, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. Meeting the 3–4 CFM requirement is necessary not only for meeting code standards but also for ensuring strong energy efficiency and indoor comfort.

Your technician will also give informed guidance on addressing leakage problems, enabling you to pass the test, reduce energy bills, and enhance your home’s 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 attach our duct tester to the system’s unit or to the 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.
