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 Plumsted, NJ

In many jurisdictions, the 2015 IECC, International Energy Conservation Code governs single-family buildings, while the 2018 IECC applies to multi-family buildings. The change will set in motion important implications for home builders and HVAC contractors who operate in the state. A Duct Leakage Test in addition to a Blower Door Test is now required for new construction and remodeled homes under the 2015 rules. Did you know that improperly sealed ducts account for a major portion of air leakage in homes across 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 crucial for new and old homes alike. Keep reading to learn why duct leakage test is important and how you can benefit from them.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Plumsted, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. A duct blaster — a precision-calibrated fan — is then fitted to the duct opening. By depressurizing the system, it makes all air leaks much easier to detect.

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 — sometimes called a duct blaster test — reveals where your ducts are losing air so you can determine the most effective sealing solutions.

duct leakage test is quick, clean, and non-intrusive for residents. Most tests in Plumsted, 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 recorded in cubic feet per minute (CFM) per 100 square feet of the conditioned portion of the home. Your technician uses a nanometer to sense slight pressure changes, showing precisely how much air is escaping through the ductwork. Understanding this number helps you recognize where issues exist, plan meaningful improvements, and check your home against local energy code requirements in Plumsted, 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, the average home loses 20% to 30% of conditioned air through leaky ducts. Air from outside—whether hot or cold—entering your system forces your HVAC to work harder, increasing utility bills and reducing indoor comfort.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. Proper duct sealing helps enhance the long-term resilience of your HVAC system, lengthening its lifespan and cutting overall maintenance needs.

Duct leaks can also introduce dust, mold spores, excess humidity, 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 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 are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) allows technicians to seal leaks located inside inaccessible parts of ductwork. To apply this method, every vent is sealed aside from one access point. The HVAC system is isolated, and a machine is connected to the ducts. It pressurizes the ducts and injects fine aerosol particles that seal tiny gaps and holes that typical sealing techniques miss.

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 typical place where ducts leak air is at their joints. Ductwork is built from multiple metal sections pressed tightly with fittings and metal bands, yet these joints are rarely airtight.

As your HVAC system runs through seasonal heating and cooling, the ducts experience ongoing expansion and contraction. Over time, this movement leads to joint loosening, generating gaps and leaks — a clear reason duct leakage test is recommended for new and older homes in Plumsted, NJ.

Many energy auditors look for duct leakage by running their hands along the ducts and using a small tool to measure the width of gaps at the joints. 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 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, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Plumsted, NJ fails its duct leakage test, you are likely facing inflated heating and cooling costs — along with increased strain on your HVAC system. Meeting the 3–4 CFM requirement is important not only for the inspector, but also for maximizing energy efficiency and comfort in your home.

Your technician will also give expert suggestions on correcting leakage issues, allowing you to pass the test, lower utility expenses, and improve your home’s overall efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins with sealing all ducts and registers using duct mask tape on both 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 25 Pascals. At that point, the nanometer allows us to get an accurate duct leakage measurement.
