Duct Leakage Test in Secaucus, NJ

Make sure your HVAC system performs at its best and satisfies local energy standards with certified duct leakage test in Secaucus, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Secaucus, NJ

Numerous states and municipalities rely on the 2015 IECC, International Energy Conservation Code for single-family properties and apply the 2018 International Energy Conservation Code to multi-family properties. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test as well as a Blower Door Test in newly constructed or remodeled homes is now required in accordance with the 2015 regulations. Did you know that ductwork often causes some of the highest levels of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can cause your energy bills to rise, strain your HVAC system, and move dust and insulation around your living spaces. 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 the duct testing process in Secaucus, NJ, the technician seals all supply and return registers except for the main return or the air handler. A calibrated duct blaster fan is then mounted to the opening. This fan creates negative pressure inside the ducts, making air leakage locations easier to find.

The duct blaster works together with a precision pressure sensor to measure airflow and pinpoint leaks in the ductwork without disturbing your home. A duct leakage test — frequently called a duct blaster test — reveals air escape points in your ducts, guiding you toward the best sealing options.

duct leakage test is fast, clean, and comfortable for residents throughout the process. Most tests in Secaucus, 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 detect minimal pressure variations, revealing the amount of air leakage occurring in the duct system. Understanding this number helps you identify problem areas, evaluate potential improvements, and determine whether your home meets local energy code requirements in Secaucus, NJ.

Cost of Excessive Duct Leakage

If your home has elevated utility bills, temperature imbalances, or frequent HVAC service calls, duct leakage may be responsible. According to ENERGY STAR, typical duct systems lose 20% to 30% of conditioned air through leaks. If outdoor hot or cold air infiltrates your system, your HVAC struggles to maintain temperatures, raising energy costs and lowering comfort.

Overworked equipment also triggers more mechanical failures and costly service calls. Proper duct sealing helps protect and extend the long-term lifespan of your HVAC system, minimizing the need for repeated maintenance.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. This can increase allergy discomfort, degrade indoor air quality, and eventually cause expensive structural issues behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC calls for new homes to include duct systems that are completely sealed using efficient materials such as mastic, foil tape, and insulation. But what about leaks that lie far within enclosed wall or ceiling spaces?

Aerosol sealing technology (AeroSeal) can identify and seal leaks that lie deep inside ductwork. 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 distributes an ultra-fine aerosol sealant to fill small gaps and holes that manual sealing methods can’t access.

This method works efficiently for small to medium leaks. However, larger gaps usually require 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 frequent point of air leakage in ductwork is the joints. Multiple metal parts are pressed together using tight fittings and metal bands, although these junctions are seldom airtight.

As your HVAC system delivers heat and cooling across different seasons, the ducts constantly expand and contract. Over time, this movement leads the joints to loosen, resulting in gaps and leaks — making a duct leakage test important for new and older homes in Secaucus, NJ.

Many energy auditors identify duct leakage by moving their hands along the ducts and using a small tool to check the width of joint openings. If your duct system is missing mastic and approved tape sealing, there’s a significant chance that air leakage is happening.

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 the duct leakage test is a necessary step before securing an occupancy certificate.

If your home in Secaucus, 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 significant not only for meeting local code but also for maintaining optimal comfort and efficiency in your home.

Your technician will also recommend effective ways to fix leakage issues so you can earn a passing score, save on utilities, and improve home 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 set up the duct tester by attaching it to the unit or a main return.

The ducts are then depressurized to exactly 25 Pascals. Once this is achieved, the nanometer is used to read the duct leakage.
