Duct Leakage Test in Guttenberg, NJ

Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in Guttenberg, 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 Guttenberg, NJ

Many states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family properties and the 2018 International Energy Conservation Code for multi-family developments. The change will have some significant implications for home builders and HVAC contractors operating 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 drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test crucial for new and old homes alike. Keep reading to learn why duct leakage test is important and how you can benefit from them.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To conduct a proper duct leakage test in Guttenberg, NJ, your technician first seals all supply and return registers except the main return or air handler. A specially calibrated duct blaster fan is then connected to the opening. This fan depressurizes the ducts to help locate where air is escaping.

The duct blaster works in sync with a precision pressure sensor to assess airflow and find duct leaks without disturbing your living space. A duct leakage test — also called a duct blaster test — locates the points where duct air escapes, helping you implement the right sealing solution.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Guttenberg, 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 identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number helps you spot leakage issues, evaluate corrective measures, and determine if your home is meeting local energy code requirements in Guttenberg, NJ.

Cost of Excessive Duct Leakage

If your utility bills keep climbing, temperatures vary from room to room, or your HVAC needs constant fixing, duct leakage may be the cause. According to ENERGY STAR, the typical home loses between 20% and 30% of its conditioned air due to duct leaks. Outside air that’s too hot or too cold entering your system strains your HVAC, resulting in higher energy consumption and less comfort.

Overworked equipment also puts extra stress on the system, resulting in breakdowns and increased repair costs. 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 enable dust, mold spores, elevated moisture, and unwanted contaminants to infiltrate the duct system. This can trigger more severe allergies, diminish indoor air quality, and create expensive structural problems behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates fully sealed duct systems in new homes, made from energy-efficient materials like mastic, foil tape, and proper insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. To implement this method, every vent is covered except one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and pushes a fine aerosol sealant through them, sealing small holes that ordinary sealing methods can’t reach.

This method is very effective for minor to moderate leaks. However, substantial openings may still need traditional sealing with mastic and tape. Technicians complete before-and-after duct leakage tests to measure leakage reduction and ensure the aerosol sealing was effective.

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 warms and cools over the seasons, the ductwork expands and then contracts. 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 Guttenberg, NJ.

Many energy auditors look for duct leakage by running their hands along the ducts and using a small tool to measure the width of gaps at the joints. If your duct system lacks proper sealing with mastic and approved tape, there is a high chance that leakage is taking place.

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, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Guttenberg, NJ doesn’t receive a passing duct leakage result, you are likely overpaying for heating and cooling — and putting significant long-term strain on your HVAC setup. Meeting the 3–4 CFM requirement is crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

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 sealing all the ducts and registers with duct mask tape on both the supply and return side.

After the registers are sealed, we link the duct tester to the unit or to one main return.

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