Why Duct Leakage Test is Important In Mount Arlington, 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 present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test and a required Blower Door Test are now part of the compliance process for new construction and remodeled homes under the 2015 regulations. Did you know that ductwork is a major cause of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. This makes duct leakage test critical for both modern and older homes. Continue reading to explore why duct leakage test is important and how you benefit from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To commence a duct leakage test in Mount Arlington, NJ, your technician will seal every supply and return register except the primary return or 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, 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 efficient, mess-free, and completely non-intrusive for residents. Most tests in Mount Arlington, 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 recorded in cubic feet per minute (CFM) per 100 square feet of the conditioned portion of the home. Your technician uses a nanometer to register small pressure differences, which help calculate how much air is leaking from the ducts. Understanding this number allows you to identify concerns, evaluate upgrade opportunities, and determine whether your home fulfills local energy code requirements in Mount Arlington, NJ.

Cost of Excessive Duct Leakage

If you’re struggling with expensive utility bills, inconsistent indoor temperatures, or continual HVAC problems, duct leakage might be the culprit. According to ENERGY STAR, the average household loses 20%–30% of conditioned air because of leaking ducts. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. 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 create openings for dust, mold spores, moisture, and various contaminants to enter the duct system. This can worsen allergies, reduce indoor air quality, and even cause expensive structural damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires all newly constructed homes to have fully sealed ductwork with modern, energy-saving materials such as mastic, foil tape, and insulation. But what about leaks that occur deep behind walls or ceilings out of sight?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. To set up this method, all vents are sealed off except for a single access point. The HVAC system is isolated, and a machine is fitted to the duct system. It pressurizes the ducts and emits a fine aerosolized sealant designed to fill small leaks unreachable with standard sealing.

This method is extremely effective for sealing small to medium leaks. However, big gaps may still need manual sealing using mastic and tape. Technicians carry out leakage testing prior to and after aerosol sealing to observe the reduction and ensure treatment success.

Common Areas of Duct Leakage

The most typical location for air to escape from ducts is at the joints. Duct systems are built from multiple metal pieces pressed together with tight fittings and metal bands, but these joints are seldom completely airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly expand and contract. Over time, this movement weakens joint connections, producing gaps and leaks — making duct leakage test essential for both new and older homes in Mount Arlington, NJ.

Many energy auditors detect leaks by checking the duct surfaces by hand and using a small tool to measure joint gap width. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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

To achieve a passing duct leakage result, your system should measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler installed. For new construction, homes are required to pass a duct leakage test before an occupancy certificate can be issued.

If your home in Mount Arlington, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. Meeting the 3–4 CFM requirement is needed not only for passing inspections, but also for improving home comfort and energy efficiency.

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 securing duct mask tape over every duct and register 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 until they reach 25 Pascals. With them depressurized, the nanometer measures the amount of leakage.
