Duct Leakage Test in Beachwood, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Beachwood, NJ. Our certified technicians locate and quantify air leaks in duct systems so homeowners and builders can enhance comfort, lower energy loss, and comply with state regulations.

Why Duct Leakage Test is Important In Beachwood, NJ

States and municipalities have adopted 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 present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test as well as the required Blower Door Test must now be performed on new or remodeled homes following the 2015 regulations. Did you know that duct systems contribute heavily to air leakage in homes throughout 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 necessary for homes of any age. Keep reading to discover why duct leakage test is so important and the advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Beachwood, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. A duct blaster, which is a specially calibrated fan, is then installed at the opening. The fan depressurizes the ducts, helping identify all points where air may be escaping.

The duct blaster, working hand in hand with a precision pressure sensor, measures airflow and identifies leaks in the ductwork without impacting 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 easy, clean, and unobtrusive for residents in the home. Most tests in Beachwood, NJ finish within 30 to 60 minutes, and the benefits to your home’s comfort and efficiency can last for years.

How to Measure Duct Leakage

Duct leakage is rated in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned zone. Your technician uses a nanometer to read small pressure variations, helping determine the volume of air escaping through the ducts. Understanding this number helps you uncover weak points, analyze opportunities for upgrades, and check whether your home follows local energy code requirements in Beachwood, 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, typical duct systems lose 20% to 30% of conditioned air through leaks. Hot or cold outside air entering your system forces your HVAC system to work harder, driving up energy costs and reducing comfort.

Overworked equipment also accelerates wear and tear, resulting in more breakdowns and costly repairs. 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 pull in dust, mold spores, moisture, and numerous contaminants into the duct system. This can worsen allergy conditions, affect indoor air quality, and result in costly damage forming behind walls or ceilings over time.

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 happens when air leaks are concealed deep in the walls or ceilings?

Aerosol sealing technology (AeroSeal) is one way to reach hidden openings inside ductwork. To start this method, all vents are blocked except for one access location. The HVAC system is isolated, and a machine is attached to the ducts. It pressurizes the ducts and releases a fine sealant mist that finds and fills small holes that traditional sealing methods cannot access.

This method is effective for addressing small to medium leaks. However, larger holes still need manual sealing with 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 common location for air leakage in ducts is the joints. Ductwork includes several metal sections pressed together with tight fittings and metal bands, but those connections are almost never airtight.

As your HVAC system heats and cools throughout the year, the ducts expand and contract. Over time, this movement compromises the joints, forming gaps and leaks — which is exactly why duct leakage test is encouraged for new and older homes in Beachwood, NJ.

Many energy auditors look for leaks by feeling the ducts and using a small tool to evaluate how wide the gaps at the joints are. If your duct system has not received sealing with mastic and approved tape, leakage is very probable.

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

To achieve a passing duct leakage result, your system needs to measure under 4 CFM per 100 square feet when the air handler is included, or 3 CFM per 100 square feet when it is not. For new construction, passing a duct leakage test is required before a home can receive an occupancy certificate.

If your home in Beachwood, NJ does not pass its duct leakage inspection, you’re likely paying higher heating and cooling bills — and stressing your HVAC system over time. Meeting the 3–4 CFM requirement is key not only for staying code-compliant but for maintaining energy efficiency and consistent comfort in your home.

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 with all ducts and registers being sealed using 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 placed under 25 Pascals of negative pressure. With the ducts depressurized, we obtain the leakage reading using the nanometer.
