Duct Leakage Test in Edgewater Park, NJ

Keep your HVAC system energy-efficient and up to code with accurate duct leakage test in Edgewater Park, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Edgewater Park, NJ

Numerous states and municipalities rely on the 2015 IECC, International Energy Conservation Code for single-family properties and apply the 2018 International Energy Conservation Code to multi-family properties. The change will carry significant implications for home builders and HVAC contractors serving communities in the state. A Duct Leakage Test together with a Blower Door Test has become mandatory for any newly constructed or remodeled home under the 2015 code. Did you know that ducts often contribute significantly to air leakage problems in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can lead to rising energy bills, added strain on your HVAC system, and unwanted insulation and dust spreading through your home. This makes duct leakage test a crucial step for maintaining comfort in new and old homes alike. Continue reading to learn why duct leakage test is valuable and how it benefits you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To get started with a duct leakage test in Edgewater Park, NJ, the technician will block every supply and return register except the main return or air handler. 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 system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. A duct leakage test — often referred to as a duct blaster test — identifies air loss in your ducts, allowing you to find the most effective ways to seal them.

duct leakage test is quick, clean, and non-intrusive for residents. Most tests in Edgewater Park, NJ require only 30 to 60 minutes, yet the upgrades can improve your home’s comfort and efficiency well into the future.

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 identify pressure differences, which provide a clear picture of how much air is leaking from the ductwork. Understanding this number helps you uncover weak points, analyze opportunities for upgrades, and check whether your home follows local energy code requirements in Edgewater Park, NJ.

Cost of Excessive Duct Leakage

If high utility expenses, irregular temperatures, or repeated HVAC troubles sound familiar, duct leakage might be the root cause. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. If outdoor hot or cold air infiltrates your system, your HVAC struggles to maintain temperatures, raising energy costs and lowering comfort.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter the duct system. This can make allergies worse, impact indoor air quality, and result in costly structural damage behind walls or ceilings as time passes.

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 about leaks located deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) makes it possible to seal leaks found deep within the ductwork. To execute this method, all vents are sealed shut except a single access point. The HVAC system is isolated, and a machine is attached to the duct network. It pressurizes the ducts and releases a delicate aerosol sealant that settles into small gaps and holes traditional techniques can’t access.

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians conduct a duct leakage test before and after aerosol sealing to measure how much the leakage has been reduced and ensure the treatment is successful.

Common Areas of Duct Leakage

The most typical place where ducts leak air is at their joints. Ductwork is built from multiple metal sections pressed tightly with fittings and metal bands, yet these joints are rarely airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly expand and contract. Over time, this movement allows the joints to loosen, producing gaps and leaks — which is why a duct leakage test is suggested for homes of all ages in Edgewater Park, 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 wasn’t properly sealed using mastic and approved tape, air leakage is very likely occurring.

What Is an Acceptable Amount of Duct Leakage per Energy Code?

To achieve a passing duct leakage result, your system must measure under 4 CFM per 100 square feet with the air handler in place, or 3 CFM per 100 square feet if the air handler is not installed. For new construction, no home can receive an occupancy certificate without first passing a duct leakage test.

If your home in Edgewater Park, NJ falls short in a duct leakage test, you are probably paying extra for heating and cooling — and placing lasting pressure on your HVAC equipment. 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 recommend effective ways to fix leakage issues so you can earn a passing score, save on utilities, and improve home 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 position the duct tester on the HVAC unit or on a primary return.

The ducts are then depressurized until they reach 25 Pascals. With them depressurized, the nanometer measures the amount of leakage.
