Maintain top HVAC efficiency and stay aligned with local energy codes using trusted duct leakage test in Tabernacle 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 Tabernacle township, NJ

Across many states and municipalities, the 2015 IECC, International Energy Conservation Code applies to single-family homes, while the 2018 International Energy Conservation Code governs multi-family buildings. The change will lead to several key implications for home builders and HVAC contractors working across the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under the 2015 regulations. Did you know that improperly sealed ducts account for a major portion of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can drive up your utility costs, tax your HVAC equipment, and circulate insulation debris and dust throughout your home. This makes duct leakage test vital for homes both old and newly built. Keep reading to find out why duct leakage test matters and what benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start a duct leakage test in Tabernacle township, NJ, the technician will close and seal every supply and return register except the main return or air handler. A specially calibrated duct blaster fan is then secured to the opening. Its job is to depressurize the duct system, allowing air leaks to reveal themselves clearly.

The duct blaster uses its precision pressure sensor partner to measure airflow and uncover duct leaks without causing any home disruption. A duct leakage test — sometimes called a duct blaster test — detects air loss in the duct system, allowing you to apply the most suitable sealing solutions.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Tabernacle township, NJ are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

How to Measure Duct Leakage

Duct leakage is determined in cubic feet per minute (CFM) for every 100 square feet of conditioned interior space. Your technician uses a nanometer to evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number gives you insight into problem areas, helps you plan improvements, and ensures your home meets local energy code requirements in Tabernacle township, NJ.

Cost of Excessive Duct Leakage

If your home suffers from costly utility bills, uneven comfort levels, or persistent HVAC repairs, duct leakage may be contributing. According to ENERGY STAR, the average household loses 20%–30% of conditioned air because of leaking ducts. Hot or cold outside air creeping into your system forces the HVAC to work inefficiently, increasing energy spending and reducing comfort.

Overworked equipment also heightens the chance of system failures and expensive repairs. Proper duct sealing helps maintain the long-term health of your HVAC system, extending its lifespan and reducing ongoing maintenance needs.

Duct leaks can also create openings for dust, mold spores, moisture, and various contaminants to enter the duct system. This can worsen allergy reactions, negatively affect indoor air quality, and contribute to costly hidden structural damage over the years.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC instructs that new homes incorporate fully sealed duct systems using high-efficiency materials, including mastic, foil tape, and insulation. But what if the leaks are buried far inside your walls or ceilings?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. 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 injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. 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 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 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 Tabernacle township, NJ.

Many energy auditors examine duct leakage by touching the ducts and using a small tool to measure the gap width between joints. If your duct system is missing mastic and approved tape sealing, there’s a significant chance that air leakage is happening.

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

To achieve a passing duct leakage result, your system needs to be under 4 CFM per 100 square feet when the air handler is installed, or 3 CFM per 100 square feet when it isn’t. For new construction, a duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Tabernacle township, NJ doesn’t pass its duct leakage evaluation, you’re likely paying more for temperature control — and contributing to long-term HVAC strain. 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 offer professional recommendations to tackle leakage issues so you can secure a passing score, reduce utility costs, and strengthen home performance.

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 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.
