Duct Leakage Test in Glassboro borough, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Glassboro borough, NJ. Our certified technicians test and measure ductwork air leaks, helping homeowners and builders improve overall comfort, reduce wasted energy, and comply with state mandates.

Why Duct Leakage Test is Important In Glassboro borough, NJ

Across different states and municipalities, the 2015 IECC, International Energy Conservation Code regulates single-family structures, and the 2018 International Energy Conservation Code is used for multi-family structures. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test together with a Blower Door Test must now be performed in all newly built or remodeled homes to comply with 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 cause higher energy expenses, burden your HVAC system, and push dust and insulation into different areas of your home. This makes duct leakage test valuable for new and existing homes alike. Read on to learn why duct leakage test is important and how it can help you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To prepare for a duct leakage test in Glassboro borough, NJ, the technician seals every supply and return register, leaving only the main return or air handler unsealed. 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 collaborates with a precision pressure sensor to evaluate airflow and locate leaks throughout the ductwork without disturbing your household. A duct leakage test — sometimes referred to as a duct blaster test — uncovers air leaks in your ductwork so you can determine the ideal sealing approach.

duct leakage test is efficient, mess-free, and completely non-intrusive for residents. Most tests in Glassboro borough, NJ are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

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 relies on a nanometer to read slight pressure variations that show the amount of air leaking through the duct system. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Glassboro borough, NJ.

Cost of Excessive Duct Leakage

If you’re encountering increased energy bills, temperature inconsistencies, or constant HVAC repairs, duct leakage could be the source. According to ENERGY STAR, the majority of homes lose 20% to 30% of conditioned air through duct leaks. 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 leads to more breakdowns and costly repairs. Proper duct sealing helps protect and extend the long-term lifespan of your HVAC system, minimizing the need for repeated maintenance.

Duct leaks can also introduce dust, mold spores, excess humidity, and other contaminants into the duct system. This can make allergies more severe, reduce the quality of indoor air, and produce costly structural harm behind walls or ceilings as time progresses.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to use fully sealed duct systems crafted from up-to-date, efficient materials such as mastic, foil tape, and insulation. But what happens when leaks are trapped deep inside wall or ceiling cavities?

Aerosol sealing technology (AeroSeal) makes it possible to seal leaks found deep within the 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 distributes an ultra-fine aerosol sealant to fill small gaps and holes that manual sealing methods can’t access.

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 test the ducts for leakage before and after aerosol sealing to determine the reduction level and verify success.

Common Areas of Duct Leakage

The most frequent area where ducts lose air is at the joints. Ductwork consists of several metal sections pressed together with tight fittings and metal bands, yet these connections are almost never fully airtight.

As your HVAC system delivers heat and cooling across different seasons, the ducts constantly expand and contract. Over time, this movement causes the joints to loosen, creating gaps and leaks — which is why a duct leakage test is recommended for both new and older homes in Glassboro borough, 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 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 measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler installed. For new construction, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Glassboro borough, 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 fundamental not only for code adherence but for boosting your home’s long-term efficiency and comfort.

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 sealing each duct and register using duct mask tape on the supply and return sides.

After the registers are sealed, we position the duct tester on the HVAC unit or on a primary return.

The ducts are then depressurized to exactly 25 Pascals. Once this is achieved, the nanometer is used to read the duct leakage.
