Duct Leakage Test in Camden, NJ

Enhance your HVAC system’s efficiency and satisfy energy regulations through precise duct leakage test in Camden, NJ. Our certified technicians assess and measure air leaks in ducts to help homeowners and builders increase comfort, reduce energy inefficiencies, and ensure state compliance.

Why Duct Leakage Test is Important In Camden, 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 create considerable implications for home builders and HVAC contractors carrying out projects in the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under 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 important for all types of homes, whether new or old. Continue reading to learn why duct leakage test is essential and how you can benefit.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Camden, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. A specially calibrated device known as a duct blaster is then attached to the duct opening. Its purpose is to depressurize the system so that escaping air can be detected.

The duct blaster teams up with a precision pressure sensor to measure airflow accurately and locate duct leaks without affecting your 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 efficient, clean, and performed without bothering residents. Most tests in Camden, NJ are completed in roughly 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is reported in cubic feet per minute (CFM) per 100 square feet of conditioned home area. Your technician uses a nanometer to monitor tiny pressure fluctuations that indicate how much air is leaking through the ducts. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Camden, 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, the typical home loses between 20% and 30% of its conditioned air due to duct leaks. 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 heightens the chance of system failures and expensive repairs. Proper duct sealing helps maintain the long-term health of your HVAC system, extending its lifespan and reducing ongoing maintenance needs.

Duct leaks can also let dust, mold spores, moisture, and other pollutants enter 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 have fully sealed duct systems using modern, energy-efficient materials such as mastic, foil tape, and insulation. But what should you do when leaks are located deep within your walls or ceilings?

Aerosol sealing technology (AeroSeal) can identify and seal leaks that lie deep inside ductwork. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and releases a fine sealant mist that finds and fills small holes that traditional sealing methods cannot access.

This method works very well for small to medium leaks. However, larger openings may still need to be sealed manually with mastic and tape. Technicians conduct a duct leakage test before and after aerosol sealing to measure how much the leakage has been reduced and ensure the treatment is successful.

Common Areas of Duct Leakage

The most common area where ducts leak air is around the joints. Ductwork uses several metal parts pressed together with tight fittings and metal bands, though these points are rarely airtight.

As your HVAC system regulates temperatures through the seasons, the ducts expand when heated and contract when cooled. 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 Camden, NJ.

Many energy auditors detect duct leakage by physically checking the ducts and using a small tool to assess the width of joint gaps. If your duct system isn’t sealed with mastic and approved tape, there’s a good chance that leaks are occurring.

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

To achieve a passing duct leakage result, your system has to be under 4 CFM per 100 square feet when the air handler is in place, or 3 CFM per 100 square feet without it installed. For new construction, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Camden, NJ cannot achieve a passing duct leakage score, you are likely wasting money on heating and cooling — and increasing wear on your HVAC system over time. Meeting the 3–4 CFM requirement is essential not only for code compliance but also for protecting your home’s energy 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 the technician sealing all ducts and registers using duct mask tape across the supply and return sides.

After the registers are sealed, we attach the duct tester to either the unit itself or a main return.

The ducts are then set to a depressurized pressure of 25 Pascals. Once there, we use the nanometer to capture the leakage reading.
