Duct Leakage Test in Haddon Heights, NJ

Ensure proper HVAC performance and code compliance by scheduling professional duct leakage test in Haddon Heights, NJ. Our certified technicians measure and identify ductwork air leaks, assisting homeowners and builders in boosting comfort, limiting energy waste, and maintaining state compliance.

Why Duct Leakage Test is Important In Haddon Heights, NJ

Across the country, states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will create considerable implications for home builders and HVAC contractors carrying out projects in the state. A Duct Leakage Test along with the required Blower Door Test must now be conducted on any newly built or remodeled home as per the 2015 regulations. Did you know that duct leakage is one of the top reasons for air loss in homes in 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 an essential part of maintaining both new and older homes. Keep reading to discover why duct leakage test is important and how it can support your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start a duct leakage test in Haddon Heights, NJ, the technician will close and seal every supply and return register except the main return or 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 uses its precision pressure sensor partner to measure airflow and uncover duct leaks without causing any home disruption. 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 Haddon Heights, NJ are done in about 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency for many years.

How to Measure Duct Leakage

Duct leakage is rated in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned zone. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number helps you spot leakage issues, evaluate corrective measures, and determine if your home is meeting local energy code requirements in Haddon Heights, NJ.

Cost of Excessive Duct Leakage

If you’re experiencing spikes in utility bills, uncomfortable temperature variations, or ongoing HVAC repair needs, duct leakage may be to blame. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. When outdoor temperatures enter your system, the HVAC must work harder to compensate, resulting in higher energy costs and reduced comfort.

Overworked equipment also causes additional breakdowns and increases repair costs. Proper duct sealing helps ensure the long-term stability of your HVAC system, extending its lifespan and reducing future maintenance work.

Duct leaks can also allow the entry of dust, mold spores, moisture, and a range of contaminants into the duct system. This can trigger more severe allergies, diminish indoor air quality, and create expensive structural problems behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires newly built homes to install fully sealed duct systems using advanced materials like mastic, foil tape, and quality insulation. But what if leaks are concealed deep inside the structure of your walls or ceilings?

Aerosol sealing technology (AeroSeal) is an effective solution for reaching hidden ductwork leaks. 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 releases a fine sealant mist that finds and fills small holes that traditional sealing methods cannot access.

This method is ideal for small to medium leaks. However, any large openings will still need manual sealing with mastic and tape. Technicians carry out a duct leakage test before and after aerosol sealing to assess how much leakage has improved and ensure the treatment was effective.

Common Areas of Duct Leakage

The most common place for ducts to leak air is through the joints. Ductwork is made of multiple metal pieces pressed together using tight fittings and metal bands, but these connections are rarely airtight.

As your HVAC system warms and cools over the seasons, the ductwork expands and then contracts. 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 Haddon Heights, NJ.

Many energy auditors check for leaks by feeling along the ductwork and using a small tool to gauge the size of gaps between joints. If your duct system has not received sealing with mastic and approved tape, leakage is very probable.

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

To achieve a passing duct leakage result, your system must remain below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet if the air handler is missing. For new construction, obtaining an occupancy certificate requires passing a duct leakage test first.

If your home in Haddon Heights, 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 necessary not only for meeting code standards but also for ensuring strong energy efficiency and indoor comfort.

Your technician will also offer expert guidance on fixing leakage problems so you can earn a passing score, reduce utility costs, and enhance your home’s overall performance.

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 reduced to a depressurized state of 25 Pascals. With them depressurized, the nanometer gives us the duct leakage reading.
