Confirm your HVAC system’s efficiency and meet local inspection standards with professional duct leakage test in Pine Beach, NJ. 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 Pine Beach, NJ

States and municipalities are using the 2015 IECC, International Energy Conservation Code for single-family construction and the 2018 International Energy Conservation Code for multi-family construction. The change will have some significant implications for home builders and HVAC contractors operating in the state. A Duct Leakage Test alongside a Blower Door Test must now be completed in newly constructed or remodeled homes to meet the 2015 regulatory standards. 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 result in higher utility costs, extra load on your HVAC system, and dust and insulation traveling throughout your home. This makes duct leakage test necessary for homeowners with either older or newly built homes. Read ahead to see why duct leakage test is important and what you gain from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin a duct leakage test in Pine Beach, NJ, your technician will seal off all supply and return registers except for the main return or the air handler. A calibrated duct blaster is then secured to the opening. Its function is to depressurize the duct system, creating conditions that highlight any escaping air.

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 — sometimes labeled as a duct blaster test — finds where your ducts are leaking air so you can decide on the best sealing strategy.

duct leakage test is rapid, clean, and performed without inconvenience to residents. Most tests in Pine Beach, NJ are completed in just 30 to 60 minutes, while the benefits to comfort and efficiency can last long-term.

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 measure tiny pressure changes, revealing how much air is escaping 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 Pine Beach, 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 average household loses 20%–30% of conditioned air because of leaking ducts. 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 causes components to fail more often, leading to costly repairs. Proper duct sealing helps preserve the long-term efficiency of your HVAC system, boosting its lifespan and cutting down on regular maintenance needs.

Duct leaks can also draw in dust, mold spores, unwanted moisture, and other harmful contaminants. This can increase allergy discomfort, degrade indoor air quality, and eventually cause expensive structural issues 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 happens when leaks are hidden deep inside walls or ceilings?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. 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 sprays a fine mist of sealant that fills tiny leaks and holes beyond the reach of conventional sealing.

This method is effective at treating small to medium leaks. However, big openings may still need to be addressed with manual mastic-and-tape sealing. Technicians use before-and-after duct leakage tests to measure improvement and make sure the aerosol sealing process was successful.

Common Areas of Duct Leakage

The most usual area for air leakage in ducts is at the joints. Ductwork includes various metal pieces pressed together using tight fittings and metal bands, but these connections are hardly ever airtight.

As your HVAC system cycles through heating and cooling each year, the ducts naturally expand and contract. Over time, this movement makes the joints loosen, forming gaps and leaks — meaning a duct leakage test is advised for both new and older homes in Pine Beach, NJ.

Many energy auditors examine duct leakage by touching the ducts and using a small tool to measure the gap width between joints. If your duct system has not been sealed with mastic and approved tape, there is a high chance that leakage is occurring.

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

To achieve a passing duct leakage result, your system is required to measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet when it isn’t installed. For new construction, a passing duct leakage test is a required step before final occupancy certification can be awarded.

If your home in Pine Beach, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. Meeting the 3–4 CFM requirement is necessary not only for meeting code standards but also for ensuring strong energy efficiency and indoor comfort.

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 technicians sealing all ducts and registers using duct mask tape on the supply and return sides.

After the registers are sealed, we install the duct tester on the unit or on a main return.

The ducts are then placed under 25 Pascals of negative pressure. With the ducts depressurized, we obtain the leakage reading using the nanometer.
