Why Duct Leakage Test is Important In Essex Fells, NJ

States and municipalities now follow the 2015 IECC, International Energy Conservation Code for single-family residences, as well as the 2018 International Energy Conservation Code for multi-family structures. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test together with a Blower Door Test must now be performed in all newly built or remodeled homes to comply with the 2015 regulations. Did you know that ductwork often causes some of the highest levels of air leakage in homes throughout 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 highly important for homes of any age. Read on to learn why duct leakage test matters and the benefits you can gain.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Essex Fells, NJ, your technician seals all supply and return registers, leaving only the main return or air handler open. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

The duct blaster works together with a precision pressure sensor to measure airflow and pinpoint leaks in the ductwork 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 straightforward, clean, and designed to be non-intrusive for residents. Most tests in Essex Fells, NJ are completed within 30 to 60 minutes, and the improvements can benefit your home’s comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is monitored in cubic feet per minute (CFM) per 100 square feet of the conditioned sections of the home. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number enables you to recognize problem areas, consider efficiency improvements, and verify that your home meets local energy code requirements in Essex Fells, 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, the average household loses 20%–30% of conditioned air because of leaking ducts. If hot or cold air from outdoors enters your system, your HVAC works harder than necessary, causing energy costs to rise and comfort to fall.

Overworked equipment also causes additional breakdowns and increases repair costs. Proper duct sealing helps promote the long-term integrity of your HVAC system, extending its lifespan and limiting continued maintenance needs.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne 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 ensures that new homes are built with duct systems sealed entirely using efficient materials such as mastic, foil tape, and insulation. But what if the leaks are buried far inside your walls or ceilings?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. To apply this method, every vent is sealed aside from one access point. The HVAC system is isolated, and a machine is connected to the ducts. It pressurizes the ducts and sends a fine aerosol sealant through the system, closing small gaps that normal sealing approaches can’t reach.

This method handles small to medium leaks very effectively. However, large openings may still require traditional mastic and tape sealing. Technicians conduct duct leakage test before and after aerosol sealing to see how much the leakage dropped and ensure the treatment worked properly.

Common Areas of Duct Leakage

The most common area where ducts leak air is around the joints. Ductwork uses several metal parts pressed together with tight fittings and metal bands, though these points are rarely airtight.

As your HVAC system transitions between warm and cool air throughout the year, the ducts expand and contract. Over time, this movement causes joints to lose their seal, creating gaps and leaks — making a duct leakage test valuable for any home in Essex Fells, NJ, whether new or old.

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 lacks sealing with mastic and approved tape, there is a strong chance that leakage is present.

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, builders must ensure the home passes a duct leakage test before an occupancy certificate is granted.

If your home in Essex Fells, 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 important not only for the inspector, but also for maximizing energy efficiency and comfort in your home.

Your technician will also provide expert strategies to address leakage concerns, helping you achieve a passing score, bring down utility bills, and boost home 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 attach our duct tester to the system’s unit or to the main return.

The ducts are then depressurized to a level of 25 Pascals. Once depressurized, the nanometer provides an accurate duct leakage reading.
