Duct Leakage Test in Ramsey, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Ramsey, 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 Ramsey, NJ

Across many states and municipalities, the 2015 IECC, International Energy Conservation Code applies to single-family homes, while the 2018 International Energy Conservation Code governs multi-family buildings. The change will have some significant implications for home builders and HVAC contractors operating 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 a significant source of air leakage in residential properties across Pennsylvania, New Jersey, and Delaware? Leaked air can push your energy bills higher, pressure your HVAC system, and spread dust and insulation inside your house. 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 start conducting a duct leakage test in Ramsey, NJ, the technician seals all supply and return registers other than the main return or the air handler. A calibrated duct blaster is then mounted to the opening. By depressurizing the duct system, it creates ideal conditions for detecting air leaks.

The duct blaster uses a precision pressure sensor to monitor airflow and pinpoint leaks throughout the ductwork without interrupting your home environment. 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 quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Ramsey, 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 quantified in cubic feet per minute (CFM) for each 100 square feet of conditioned living space. Your technician uses a nanometer to read small pressure variations, helping determine the volume of air escaping through the ducts. Understanding this number helps you locate trouble spots, review possible upgrades, and see if your home complies with local energy code requirements in Ramsey, NJ.

Cost of Excessive Duct Leakage

If you’re facing higher energy bills, uneven heating or cooling, or recurring HVAC repairs, duct leakage could be to blame. According to ENERGY STAR, many homes lose as much as 20% to 30% of conditioned air through duct leaks. When outside hot or cold air seeps into your system, your HVAC must compensate, leading to higher energy costs and diminished comfort.

Overworked equipment also causes components to fail more often, leading to costly 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 enable dust, mold spores, elevated moisture, and unwanted contaminants to infiltrate 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 ensures that new homes are built with duct systems sealed entirely using 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) helps target hard-to-reach openings deep within ducts. To carry out this method, every vent is sealed except a single access point. The HVAC system is separated, and a machine is attached to the duct system. It pressurizes the ducts and injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method provides strong results for small and medium leaks. However, significant openings may still require mastic and tape by hand. Technicians perform a duct leakage test both before and after aerosol sealing to determine how much leakage has decreased and confirm the treatment worked.

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 transitions between warm and cool air throughout the year, the ducts expand and contract. Over time, this movement leads to joint loosening, generating gaps and leaks — a clear reason duct leakage test is recommended for new and older homes in Ramsey, 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 been properly sealed with mastic and approved tape, it’s very likely that leakage exists.

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, homes are required to pass a duct leakage test before an occupancy certificate can be issued.

If your home in Ramsey, NJ fails a duct leakage test, you are probably spending more than you should on heating and cooling — while also putting long-term stress on your HVAC system. Meeting the 3–4 CFM requirement is essential not only for following building code, but for keeping your home comfortable and energy-efficient.

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 duct mask tape being placed on all ducts and registers on both the supply and return sides.

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

The ducts are then depressurized to a level of 25 Pascals. Once depressurized, the nanometer provides an accurate duct leakage reading.
