Duct Leakage Test in Aberdeen, NJ

Make sure your HVAC system performs at its best and satisfies local energy standards with certified duct leakage test in Aberdeen, 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 Aberdeen, NJ

Many states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family properties and the 2018 International Energy Conservation Code for multi-family developments. The change will result in significant implications for home builders and HVAC contractors doing business 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 ducts are one of the primary sources of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can lead to rising energy bills, added strain on your HVAC system, and unwanted insulation and dust spreading through your home. This makes duct leakage test necessary for homes of any age. Keep reading to discover why duct leakage test is so important and the advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To get started with a duct leakage test in Aberdeen, NJ, the technician will block every supply and return register except the main return or air handler. A specially calibrated duct blaster is then installed onto the opening. The fan lowers the pressure inside the ducts, helping reveal any leakage points.

The duct blaster functions with a precision pressure sensor to analyze airflow and spot leaks in the duct system without affecting your home’s comfort. 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 swift, clean, and carried out with no disturbance to residents. Most tests in Aberdeen, NJ take only 30 to 60 minutes, yet the comfort and efficiency gains can last for years.

How to Measure Duct Leakage

Duct leakage is tracked in cubic feet per minute (CFM) per 100 square feet of conditioned living area. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Aberdeen, NJ.

Cost of Excessive Duct Leakage

If high utility expenses, irregular temperatures, or repeated HVAC troubles sound familiar, duct leakage might be the root cause. According to ENERGY STAR, an average home’s ductwork loses 20% to 30% of conditioned air through leaks. If outdoor hot or cold air infiltrates your system, your HVAC struggles to maintain temperatures, raising energy costs and lowering comfort.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. 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 permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. This can make allergies worse, impact indoor air quality, and result in costly structural damage behind walls or ceilings as time passes.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC sets a requirement that all new homes feature ducts sealed completely with modern materials like mastic, foil tape, and insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) gives technicians a way to reach concealed duct leaks without opening walls or ceilings. To implement this method, every vent is covered except one access point. The HVAC system is isolated, and a machine is connected to 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 extremely effective for sealing small to medium leaks. However, big gaps may still need manual sealing using mastic and tape. Technicians perform pre- and post-aerosol sealing duct leakage tests to measure the improvement and confirm treatment effectiveness.

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 transitions between warm and cool air throughout the year, the ducts expand and contract. Over time, this movement leads the joints to loosen, resulting in gaps and leaks — making a duct leakage test important for new and older homes in Aberdeen, NJ.

Many energy auditors evaluate duct leakage by feeling around the duct system and using a small tool to check the size of joint gaps. 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 must measure under 4 CFM per 100 square feet with the air handler in place, or 3 CFM per 100 square feet if the air handler is not installed. For new construction, passing the duct leakage test is a necessary step before securing an occupancy certificate.

If your home in Aberdeen, NJ does not pass a duct leakage test, you are likely paying more than necessary for heating and cooling — and placing long-term strain on your HVAC equipment. Meeting the 3–4 CFM requirement is required not only for code approval but for keeping your home efficient and comfortable.

Your technician will also share expert solutions for tackling leakage problems so you can pass the test, cut down utility expenses, and improve overall comfort and efficiency.

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 hook the duct tester to the HVAC unit or a main return.

The ducts are then brought down to 25 Pascals of pressure. With the ducts depressurized, the nanometer can be used to read the leakage level.
