Keep your HVAC system running at peak efficiency and in full compliance with local codes through expert duct leakage test in Parsip Pany-Troy Hills, NJ. Our certified technicians trace and measure duct leaks, supporting homeowners and builders in enhancing comfort, lowering energy waste, and staying compliant with state codes.

Why Duct Leakage Test is Important In Parsip Pany-Troy Hills, NJ

States and municipalities are using the 2015 IECC, International Energy Conservation Code for single-family construction and the 2018 International Energy Conservation Code for multi-family construction. The change will create several important implications for home builders and HVAC contractors operating within the state. A Duct Leakage Test plus a Blower Door Test are now compulsory in newly constructed or renovated homes according to the 2015 regulations. Did you know that ducts are frequently the biggest contributors to home air loss in Pennsylvania, New Jersey, and Delaware? Leaked air can boost your energy bills, overload your HVAC system, and send dust and insulation particles throughout your home. This makes duct leakage test indispensable no matter the age of your home. Continue reading to understand why duct leakage test is important and the benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Parsip Pany-Troy Hills, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. A specially calibrated fan known as a duct blaster is then put in place at the opening. It depressurizes the ductwork so escaping air can be accurately identified.

The duct blaster operates alongside a precision pressure sensor to track airflow and identify duct leaks without disrupting your home. 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 fast, tidy, and causes no disruption for residents. Most tests in Parsip Pany-Troy Hills, NJ take around 30 to 60 minutes, but the efficiency and comfort improvements can last for many years.

How to Measure Duct Leakage

Duct leakage is expressed in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned area. Your technician uses a nanometer to pick up minor pressure shifts that indicate the level of air leakage within the ducts. Understanding this number lets you identify inefficiencies, weigh improvement options, and confirm your home’s compliance with local energy code requirements in Parsip Pany-Troy Hills, NJ.

Cost of Excessive Duct Leakage

If elevated utility bills, shifting temperatures, or repeated HVAC issues occur in your home, duct leakage may be the factor behind them. According to ENERGY STAR, the average duct system loses between 20% and 30% of its conditioned air due to leaks. When hot or cold outside air enters your system, your HVAC has to work harder, increasing energy costs and lowering overall comfort.

Overworked equipment also increases the likelihood of breakdowns and drives up repair costs. Proper duct sealing helps support the long-term durability of your HVAC system, lengthening its lifespan and minimizing ongoing maintenance demands.

Duct leaks can also let in dust, mold spores, added moisture, and other harmful contaminants. This can escalate allergies, lower the overall air quality indoors, and lead to costly damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC instructs that new homes incorporate fully sealed duct systems using high-efficiency materials, including mastic, foil tape, and insulation. But what happens when leaks are hidden deep inside walls or ceilings?

Aerosol sealing technology (AeroSeal) helps seal hard-to-find openings within the duct system. 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 releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods 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 use a duct leakage test before and after aerosol sealing to evaluate how much leakage has been lowered and verify the results.

Common Areas of Duct Leakage

The most common spot where air escapes in duct systems is the joints. Ductwork features several metal pieces pressed together using tight fittings and metal bands, though these areas are seldom airtight.

As your HVAC system adjusts temperatures throughout the year, the ducts go through expansion and contraction. 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 Parsip Pany-Troy Hills, NJ.

Many energy auditors look for duct leakage by running their hands along the ducts and using a small tool to measure the width of gaps at the 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, obtaining an occupancy certificate requires passing a duct leakage test first.

If your home in Parsip Pany-Troy Hills, 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 crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

Your technician will also provide expert insights into correcting leakage issues so you can meet passing standards, lower your utility expenses, and improve overall home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by securing duct mask tape over every duct and register on 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 exactly 25 Pascals. Once this is achieved, the nanometer is used to read the duct leakage.
