The change will result in several substantial implications for home builders and HVAC contractors engaged in work across 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 duct leakage is one of the most common issues affecting homes in Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. This makes duct leakage test beneficial for all homes, new or old.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in West Wildwood, NJ, the technician seals all supply and return registers other than the main return or the air handler. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

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 — widely known as a duct blaster test — pinpoints air leakage in your ducts so you can choose the best sealing methods.

duct leakage test is swift, clean, and carried out with no disturbance to residents. Most tests in West Wildwood, 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 determined in cubic feet per minute (CFM) for every 100 square feet of conditioned interior space. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in West Wildwood, NJ.

Cost of Excessive Duct Leakage

If you observe rising utility costs, temperature swings in different rooms, or regular HVAC breakdowns, duct leakage may be involved. According to ENERGY STAR, an average home’s ductwork loses 20% to 30% of conditioned air through leaks. When outdoor temperatures enter your system, the HVAC must work harder to compensate, resulting in higher energy costs and reduced comfort.

Overworked equipment also contributes to repeated breakdowns and pricey 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 introduce dust, mold spores, excess humidity, and other contaminants into the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires that all new homes feature fully sealed duct systems utilizing updated, energy-efficient materials like mastic, foil tape, and insulation. But what about leaks located deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) is used to address openings concealed inside duct systems. To complete this method, all vents are closed off except for one access opening. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and distributes a fine aerosolized sealant that seals small openings traditional methods cannot reach.

This method excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with 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 likely place for ducts to leak air is through their joints. Ductwork involves multiple metal pieces pressed together with secure fittings and metal bands, yet these connections are rarely perfectly airtight.

As your HVAC system heats and cools throughout the year, the ducts expand and contract. Over time, this movement causes the joints to loosen, opening gaps and leaks — making a duct leakage test beneficial for both new and older homes in West Wildwood, NJ.

Many energy auditors assess duct leakage by touching the ductwork and using a small tool to check the width of gaps where joints connect. 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 must remain below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet if the air handler is missing. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in West Wildwood, NJ does not pass a duct leakage test, you are likely paying more than necessary for heating and cooling — and placing long-term strain on your HVAC equipment. Meeting the 3–4 CFM requirement is key not only for staying code-compliant but for maintaining energy efficiency and consistent comfort in your home.

Your technician will also provide professional insights on resolving leakage issues so you can achieve a passing score, lower your utility costs, and optimize home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with the technician sealing all ducts and registers using duct mask tape across the supply and return sides.

After the registers are sealed, we connect the duct tester either to the HVAC unit itself or a central return.

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