Why Duct Leakage Test is Important In Eagleswood township, NJ

States and municipalities have standardized around the 2015 IECC, International Energy Conservation Code for single-family builds and the 2018 International Energy Conservation Code for multi-family builds. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under the 2015 regulations. Did you know that ducts are a significant source of air leakage in residential properties across Pennsylvania, New Jersey, and Delaware? Leaked air can increase monthly energy costs, stress your HVAC system, and scatter dust and insulation across your living areas. 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 begin a duct leakage test in Eagleswood township, NJ, your technician will seal off 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 joins forces with a precision pressure sensor to monitor airflow and pinpoint leak points in the ducts without disturbing your home. A duct leakage test — sometimes known as a duct blaster test — shows exactly where your ducts are leaking air so you can apply the right sealing fixes.

duct leakage test is straightforward, clean, and designed to be non-intrusive for residents. Most tests in Eagleswood township, NJ take 30 to 60 minutes to complete, and the benefits to comfort and efficiency can endure for years.

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 measure tiny pressure changes, revealing how much air is escaping through the ducts. Understanding this number helps you spot leakage issues, evaluate corrective measures, and determine if your home is meeting local energy code requirements in Eagleswood township, NJ.

Cost of Excessive Duct Leakage

If you’re seeing higher energy bills, irregular heating or cooling, or frequent HVAC malfunctions, duct leakage may be at fault. According to ENERGY STAR, most homes lose 20% to 30% of their conditioned air through leaking ductwork. 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 heightens the chance of system failures and expensive repairs. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also allow the entry of dust, mold spores, moisture, and a range of contaminants into the duct system. This can negatively influence allergies, weaken indoor air quality, and lead to expensive long-term 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 do you do about leaks that sit deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) gives technicians a way to reach concealed duct leaks without opening walls or ceilings. 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 releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method seals small to medium leaks effectively. However, large gaps may still call for manual sealing using mastic and tape. Technicians use a duct leakage test before and after aerosol sealing to evaluate how much leakage has been lowered and verify the results.

Common Areas of Duct Leakage

The most usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system moves through annual heating and cooling cycles, the ductwork expands and then contracts. 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 Eagleswood township, NJ.

Many energy auditors check duct leakage by feeling around the ducts and using a small tool to test the width of gaps between joints. If your duct system wasn’t sealed using mastic and approved tape, there is a strong chance that air leaks are occurring.

What Is an Acceptable Amount of Duct Leakage per Energy Code?

To achieve a passing duct leakage result, your system must come in under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is removed. For new construction, a passing duct leakage test is a required step before final occupancy certification can be awarded.

If your home in Eagleswood township, NJ does not pass its duct leakage inspection, you’re likely paying higher heating and cooling bills — and stressing your HVAC system over time. Meeting the 3–4 CFM requirement is needed not only for passing inspections, but also for improving home comfort and energy efficiency.

Your technician will also offer professional recommendations to tackle leakage issues so you can secure a passing score, reduce utility costs, and strengthen home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with all ducts and registers being sealed using duct mask tape on the supply and return sides.

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

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
