The change will set in motion important implications for home builders and HVAC contractors who operate in 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 ducts are one of the primary sources of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test beneficial for all homes, new or old. Keep reading to find out why duct leakage test is essential and how it can improve your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start a duct leakage test in Beach Haven borough, NJ, the technician will close and seal every supply and return register except the main return or air handler. A duct blaster — a specially calibrated fan — is then connected to the opening. It depressurizes the duct system to expose areas 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 — 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 quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Beach Haven borough, NJ finish within 30 to 60 minutes, and the benefits to your home’s comfort and efficiency can last for years.

How to Measure Duct Leakage

Duct leakage is expressed in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned area. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Beach Haven borough, NJ.

Cost of Excessive Duct Leakage

If you’re experiencing spikes in utility bills, uncomfortable temperature variations, or ongoing HVAC repair needs, duct leakage may be to blame. According to ENERGY STAR, duct leakage causes homeowners to lose 20%–30% of their conditioned air on average. When your system pulls in hot or cold outdoor air, the HVAC unit has to work harder, driving up energy usage and reducing comfort indoors.

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

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter the duct system. This can intensify allergy symptoms, harm indoor air quality, and cause long-term structural damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC specifies that newly constructed homes must use fully sealed duct systems with modern, efficient materials such as mastic, foil tape, and insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) can identify and seal leaks that lie deep inside ductwork. To implement this method, every vent is covered except 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 performs well for small and medium leaks. However, larger openings typically require 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 common place for ducts to leak air is through the joints. Ductwork is made of multiple metal pieces pressed together using tight fittings and metal bands, but these connections are rarely airtight.

As your HVAC system heats and cools during seasonal changes, the ductwork expands and then contracts. Over time, this movement makes joints shift and loosen, forming gaps and leaks — which is why a duct leakage test is advised for homes old and new in Beach Haven borough, NJ.

Many energy auditors investigate duct leakage by running their hands over the ducts and using a small tool to determine the width of joint gaps. If your duct system has not been properly sealed with mastic and approved tape, it’s very likely that leakage exists.

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, passing a duct leakage test is required before a home can receive an occupancy certificate.

If your home in Beach Haven borough, NJ does not meet the duct leakage requirement, you’re likely paying elevated heating and cooling costs — and overburdening your HVAC system. Meeting the 3–4 CFM requirement is required not only for code approval but for keeping your home efficient and comfortable.

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 securing duct mask tape over every duct and register on the supply and return sides.

After the registers are sealed, we fasten the duct tester to the unit or to a main return.

The ducts are then reduced to a depressurized state of 25 Pascals. With them depressurized, the nanometer gives us the duct leakage reading.
