What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Eagleswood township, NJ, your technician first seals all supply and return registers except the main return or air handler. A duct blaster fan, carefully calibrated for accuracy, is then attached to the duct opening. It depressurizes the ductwork, allowing leaks to become more noticeable.

The duct blaster system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at 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 quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Eagleswood township, NJ take just 30 to 60 minutes, and the resulting improvements can enhance your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to detect small pressure differences, which indicate how much air is leaking through the ducts. Understanding this number enables you to recognize problem areas, consider efficiency improvements, and verify that your home meets 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, the majority of homes lose 20% to 30% of conditioned air through duct leaks. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also heightens the chance of system failures and expensive repairs. Proper duct sealing helps uphold the long-term performance of your HVAC system, stretching its lifespan and decreasing routine maintenance demands.

Duct leaks can also pull dust, mold spores, excess moisture, and various 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 enforces that new homes incorporate fully sealed ducts made with modern, energy-efficient materials including mastic, foil tape, and insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) helps target hard-to-reach openings deep within ducts. To begin this method, every vent is sealed except for one access opening. The HVAC unit is isolated, and a machine is installed onto the duct system. It pressurizes the ducts and sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method is great for handling small to medium leaks. However, larger holes often require manual sealing with mastic and tape. Technicians run a duct leakage test before and after aerosol sealing to quantify the reduction in leakage and verify the success of the process.

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 operates in both heating and cooling modes year-round, the ducts continuously 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 Eagleswood township, 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 hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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 duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

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 matters not only for code compliance, but also for protecting your home’s comfort and reducing energy waste.

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 by closing off every duct and register with duct mask tape across 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 a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
