Duct Leakage Test in Haddon township, NJ

Ensure long-term HVAC performance and code compliance with expert duct leakage test in Haddon township, NJ. Our certified technicians detect and measure air leakage in ductwork, supporting homeowners and builders in improving comfort, minimizing wasted energy, and meeting state requirements.

Why Duct Leakage Test is Important In Haddon township, NJ

States and municipalities are using the 2015 IECC, International Energy Conservation Code for single-family construction and the 2018 International Energy Conservation Code for multi-family construction. The change will lead to several key implications for home builders and HVAC contractors working across 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 ductwork often causes some of the highest levels of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can push your energy bills higher, pressure your HVAC system, and spread dust and insulation inside your house. This makes duct leakage test an essential part of maintaining both new and older homes. Keep reading to discover why duct leakage test is important and how it can support your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin the process of a duct leakage test in Haddon township, NJ, your technician seals off all supply and return registers apart from the main return or air handler. A calibrated duct blaster is then secured to the opening. Its function is to depressurize the duct system, creating conditions that highlight any escaping air.

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 — sometimes labeled as a duct blaster test — finds where your ducts are leaking air so you can decide on the best sealing strategy.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Haddon township, NJ are wrapped up in 30 to 60 minutes, with improvements that continue to boost comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is measured in cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a nanometer to pick up minor pressure shifts that indicate the level of air leakage within 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 Haddon township, NJ.

Cost of Excessive Duct Leakage

If you’re encountering increased energy bills, temperature inconsistencies, or constant HVAC repairs, duct leakage could be the source. According to ENERGY STAR, the average home loses 20% to 30% of conditioned air through leaky ducts. Outside hot or cold air leaking into your system puts extra strain on your HVAC unit, raising energy bills and decreasing comfort.

Overworked equipment also accelerates wear and tear, resulting in more breakdowns and costly repairs. Proper duct sealing helps protect the long-term performance of your HVAC system, increasing its lifespan and lowering future maintenance requirements.

Duct leaks can also introduce dust, mold spores, moisture, and additional contaminants into the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires newly built homes to install fully sealed duct systems using advanced materials like mastic, foil tape, and quality insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) helps seal hard-to-find openings within the duct system. 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 injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method provides strong results for small and medium leaks. However, significant openings may still require mastic and tape by hand. Technicians use a duct leakage test before and after aerosol sealing to evaluate how much leakage has been lowered and verify the results.

Common Areas of Duct Leakage

The most usual area for air leakage in ducts is at the joints. Ductwork includes various metal pieces pressed together using tight fittings and metal bands, but these connections are hardly ever airtight.

As your HVAC system changes between heating and cooling during the year, the ducts naturally expand and shrink. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Haddon township, NJ, new or older, benefit from duct leakage test.

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 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 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, obtaining an occupancy certificate requires passing a duct leakage test first.

If your home in Haddon township, NJ fails duct leakage test, you are probably spending unnecessarily on heating and cooling — and placing ongoing stress on your HVAC equipment. Meeting the 3–4 CFM requirement is vital not only for satisfying code rules but also for preserving your home’s comfort and energy performance.

Your technician will also advise you on the best ways to address leakage issues so you can pass the test, reduce utility bills, and enhance your home’s efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins with all the ducts and registers sealed tightly using duct mask tape on both sides—supply and return.

After the registers are sealed, we install the duct tester on the unit or on a main return.

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
