Duct Leakage Test in Clayton, NJ

Ensure long-term HVAC performance and code compliance with expert duct leakage test in Clayton, 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 Clayton, NJ

In most states and municipalities, the 2015 IECC, International Energy Conservation Code is required for single-family homes, while the 2018 International Energy Conservation Code is required for multi-family homes. The change will result in significant implications for home builders and HVAC contractors doing business in the state. A Duct Leakage Test paired with a Blower Door Test is now expected for newly constructed and remodeled homes in accordance with the 2015 code requirements. 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 push your energy bills higher, pressure your HVAC system, and spread dust and insulation inside your house. This makes duct leakage test a key step for new and older homes alike. Read ahead to see why duct leakage test is needed and what advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To kick off a duct leakage test in Clayton, NJ, your technician will block all supply and return registers while keeping the main return or air handler accessible. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

The duct blaster joins forces with a precision pressure sensor to monitor airflow and pinpoint leak points in the ducts without disturbing your home. A duct leakage test — also known as a duct blaster test — pinpoints where air is escaping from your ducts, helping you choose the best sealing methods.

duct leakage test is straightforward, clean, and designed to be non-intrusive for residents. Most tests in Clayton, NJ take between 30 and 60 minutes, and the improvements they deliver can elevate comfort and efficiency for years ahead.

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 uses a nanometer to monitor tiny pressure fluctuations that indicate how much air is leaking through the ducts. Understanding this number helps you detect issues, explore potential fixes, and determine if your home aligns with local energy code requirements in Clayton, NJ.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, most households lose 20% to 30% of their heated or cooled air because of duct leaks. Outside air that’s too hot or too cold entering your system strains your HVAC, resulting in higher energy consumption and less comfort.

Overworked equipment also results in more frequent breakdowns and expensive repair bills. Proper duct sealing helps safeguard the long-term reliability of your HVAC system, extending its lifespan and reducing how often maintenance is needed.

Duct leaks can also allow the entry of dust, mold spores, moisture, and a range of contaminants into the duct system. This can increase allergy discomfort, degrade indoor air quality, and eventually cause expensive structural issues behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC states that new homes must have duct systems sealed completely with energy-efficient products 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) helps seal hard-to-find openings within the duct system. To conduct this method, all vents are blocked except for one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method is ideal for small to medium leaks. However, any large openings will still need manual sealing with 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 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 cycles through heating and cooling each year, the ducts naturally expand and contract. Over time, this movement weakens joint connections, producing gaps and leaks — making duct leakage test essential for both new and older homes in Clayton, 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 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, passing the duct leakage test is a necessary step before securing an occupancy certificate.

If your home in Clayton, NJ doesn’t pass its duct leakage evaluation, you’re likely paying more for temperature control — and contributing to long-term HVAC strain. Meeting the 3–4 CFM requirement is important not just for compliance, but for safeguarding your home’s comfort and long-term energy efficiency.

Your technician will also share expert recommendations for fixing leakage problems, helping you achieve a passing score, save on utilities, and improve 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 attach the duct tester directly to the unit or to one primary return.

The ducts are then lowered to a depressurized level of 25 Pascals. With the system at that pressure, the nanometer is used to read the duct leakage.
