Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in Pompton Lakes, NJ. Our certified technicians pinpoint and measure ductwork air leaks, helping homeowners and builders boost comfort, cut energy waste, and meet state compliance standards.

Why Duct Leakage Test is Important In Pompton Lakes, NJ

States and municipalities have put in place the 2015 IECC, International Energy Conservation Code for single-family projects and the 2018 International Energy Conservation Code for multi-family projects. The change will have some significant implications for home builders and HVAC contractors operating in the state. A Duct Leakage Test along with a Blower Door Test is now required for any newly constructed or remodeled home as outlined in the 2015 regulations. Did you know that leaking ducts are a widespread cause of air loss in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can spike your energy costs, wear down your HVAC system, and spread dust and insulation throughout various parts of 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 begin a duct leakage test in Pompton Lakes, NJ, your technician will seal off all supply and return registers except for the main return or the air handler. A specially calibrated fan, known as a duct blaster, is then attached to the opening. The purpose of this fan is to depressurize the duct system, creating the ideal conditions to identify where air is escaping.

The duct blaster, combined with a precision pressure sensor, measures airflow and detects leaks in the duct system without causing any disturbance in your home. A duct leakage test — sometimes referred to as a duct blaster test — uncovers air leaks in your ductwork so you can determine the ideal sealing approach.

duct leakage test is fast, debris-free, and completely resident-friendly. Most tests in Pompton Lakes, NJ take 30 to 60 minutes to complete, and the benefits to comfort and efficiency can endure 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 measure tiny pressure differences, making it possible to determine how much air the ducts are losing. Understanding this number gives you insight into problem areas, helps you plan improvements, and ensures your home meets local energy code requirements in Pompton Lakes, 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, a large portion of homes lose between 20% and 30% of conditioned air due to leaky ducts. Hot or cold outside air leaking in makes your HVAC system work more than it should, driving up energy costs and diminishing comfort.

Overworked equipment also makes breakdowns more common and repairs more expensive. Proper duct sealing helps sustain your HVAC system’s long-term condition, increasing its operational lifespan and decreasing maintenance requirements.

Duct leaks can also introduce dust, mold spores, excess humidity, and other 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 requires that all new homes feature fully sealed duct systems utilizing updated, energy-efficient materials like mastic, foil tape, and insulation. But what if some leaks are hidden within the depths of your walls or ceilings?

Aerosol sealing technology (AeroSeal) can access interior duct leaks that are difficult to reach manually. 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 sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method performs well for small and medium leaks. However, larger openings typically require manual sealing with 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 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 heats and cools throughout the year, the ducts expand and contract. Over time, this movement makes joints shift and loosen, forming gaps and leaks — which is why a duct leakage test is advised for homes old and new in Pompton Lakes, 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 measure below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Pompton Lakes, NJ does not meet duct leakage standards, you are likely overpaying for heating and cooling — and adding unnecessary strain to your HVAC equipment. Meeting the 3–4 CFM requirement is required not only for code approval but for keeping your home efficient and comfortable.

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 by taping off all ducts and registers with duct mask tape on the supply and return sides.

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

The ducts are then depressurized to 25 Pascals. At that point, the nanometer allows us to get an accurate duct leakage measurement.
