Duct Leakage Test in Mullica township, NJ

Improve HVAC performance and ensure energy code compliance with dependable duct leakage test in Mullica township, NJ. Our certified technicians inspect and measure air leakage in ductwork, enabling homeowners and builders to boost comfort, prevent energy waste, and adhere to state guidelines.

Why Duct Leakage Test is Important In Mullica township, NJ

In most states and municipalities, the 2015 IECC, International Energy Conservation Code is required for single-family homes, while the 2018 International Energy Conservation Code is required for multi-family homes. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test as well as a Blower Door Test in newly constructed or remodeled homes is now required in accordance with the 2015 regulations. Did you know that duct leakage is one of the top reasons for air loss in homes in Pennsylvania, New Jersey, and Delaware? Leaked air can increase monthly energy costs, stress your HVAC system, and scatter dust and insulation across your living areas. 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 initiate testing, your technician will seal all supply and return registers except for the main return or air handler during a duct leakage test in Mullica township, NJ. 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 functions with a precision pressure sensor to analyze airflow and spot leaks in the duct system without affecting your home’s comfort. A duct leakage test — commonly called a duct blaster test — detects areas where your ducts lose air, helping you select the most efficient sealing solutions.

duct leakage test is quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Mullica township, NJ take just 30 to 60 minutes, and the resulting improvements can enhance your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is reported in cubic feet per minute (CFM) per 100 square feet of conditioned home area. Your technician uses a nanometer to sense slight pressure changes, showing precisely how much air is escaping through the ductwork. Understanding this number helps you detect inefficiencies, assess needed upgrades, and ensure your home complies with local energy code requirements in Mullica 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, many homes lose as much as 20% to 30% of conditioned air through 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 sustain your HVAC system’s long-term condition, increasing its operational lifespan and decreasing maintenance requirements.

Duct leaks can also enable dust, mold spores, elevated moisture, and unwanted contaminants to infiltrate the duct system. This can increase allergy discomfort, degrade indoor air quality, and eventually cause expensive structural issues behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC enforces that new homes incorporate fully sealed ducts made with modern, energy-efficient materials including mastic, foil tape, and insulation. But what about leaks that lie far within enclosed wall or ceiling spaces?

Aerosol sealing technology (AeroSeal) is designed to reach and seal hidden gaps throughout the duct system. 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 sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using 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 common point where ducts leak air is along the joints. Ductwork is made from multiple metal pieces pressed together with tight fittings and metal bands, but these connections are rarely completely airtight.

As your HVAC system changes between heating and cooling during the year, the ducts naturally expand and shrink. Over time, this movement weakens the joints, creating gaps and leaks — a key reason duct leakage test is recommended for new and older homes in Mullica township, NJ.

Many energy auditors detect duct leakage by physically checking the ducts and using a small tool to assess the width of joint gaps. 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 should come out under 4 CFM per 100 square feet in tests with the air handler, or 3 CFM per 100 square feet without the air handler. For new construction, a duct leakage test must be successfully passed before the home can obtain an occupancy certificate.

If your home in Mullica township, NJ fails a duct leakage test, you are probably spending more than you should on heating and cooling — while also putting long-term stress on your HVAC system. Meeting the 3–4 CFM requirement is necessary not only for meeting code standards but also for ensuring strong energy efficiency and indoor comfort.

Your technician will also recommend effective ways to fix leakage issues so you can earn a passing score, save on utilities, and improve home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with sealing each duct and register using duct mask tape on the supply and return sides.

After the registers are sealed, we attach the duct tester directly to the unit or to one primary return.

The ducts are then brought down to 25 Pascals of pressure. With the ducts depressurized, the nanometer can be used to read the leakage level.
