Duct Leakage Test in Bogota, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Bogota, NJ. Our certified technicians identify and quantify air leaks in duct systems so homeowners and builders can optimize comfort, reduce energy waste, and meet state-level requirements.

Why Duct Leakage Test is Important In Bogota, NJ

Across the country, states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will introduce meaningful implications for home builders and HVAC contractors active 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 frequently the biggest contributors to home air loss in Pennsylvania, New Jersey, and Delaware? Leaked air can drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test an essential part of maintaining both new and older homes. Keep reading to discover why duct leakage test is important and how it can support your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To commence a duct leakage test in Bogota, NJ, your technician will seal every supply and return register except the primary return or air handler. A specially calibrated duct blaster fan is then secured to the opening. Its job is to depressurize the duct system, allowing air leaks to reveal themselves clearly.

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 — sometimes identified as a duct blaster test — shows where your ducts lose air, helping you plan the right sealing approach.

duct leakage test is prompt, clean, and does not interrupt residents’ activities. Most tests in Bogota, 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 defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number helps you detect issues, explore potential fixes, and determine if your home aligns with local energy code requirements in Bogota, 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 creates more wear, leading to breakdowns and costly fixes. Proper duct sealing helps preserve the long-term efficiency of your HVAC system, boosting its lifespan and cutting down on regular maintenance needs.

Duct leaks can also allow the entry of dust, mold spores, moisture, and a range of contaminants into the duct system. This can intensify allergy symptoms, harm indoor air quality, and cause long-term structural damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC enforces that new homes incorporate fully sealed ducts made with modern, energy-efficient materials including mastic, foil tape, and insulation. But what happens when air leaks are concealed deep in the walls or ceilings?

Aerosol sealing technology (AeroSeal) provides a way to seal concealed openings inside the duct system. To initiate this method, technicians seal every vent except one access point. The HVAC system is isolated, and a machine is connected to the ductwork. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians do a duct leakage test before and after aerosol sealing to calculate how much leakage has been reduced and validate the results.

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 shifts between hot and cold cycles all year long, the ductwork expands and contracts. 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 Bogota, NJ.

Many energy auditors locate duct leakage by touching the ductwork and using a small tool to measure the width of separation between joints. 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 should fall under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is absent. For new construction, a passing duct leakage test is essential before the home can qualify for an occupancy certificate.

If your home in Bogota, 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 fundamental not only for code adherence but for boosting your home’s long-term efficiency and comfort.

Your technician will also give informed guidance on addressing leakage problems, enabling you to pass the test, reduce energy bills, and enhance your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by covering all ducts and registers with duct mask tape on both 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 depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
