Duct Leakage Test in Wildwood Crest, NJ

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Wildwood Crest, NJ. Our certified technicians trace and measure duct leaks, supporting homeowners and builders in enhancing comfort, lowering energy waste, and staying compliant with state codes.

Why Duct Leakage Test is Important In Wildwood Crest, 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 introduce meaningful implications for home builders and HVAC contractors active 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 ductwork is a major cause of air leakage in homes across Pennsylvania, New Jersey, and Delaware? Leaked air can increase your energy costs, overwork your HVAC system, and distribute insulation particles and dust around 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 prepare for a duct leakage test in Wildwood Crest, NJ, the technician seals every supply and return register, leaving only the main return or air handler unsealed. 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 uses a precision pressure sensor to monitor airflow and pinpoint leaks throughout the ductwork without interrupting your home environment. A duct leakage test — often referred to as a duct blaster test — identifies air loss in your ducts, allowing you to find the most effective ways to seal them.

duct leakage test is efficient, mess-free, and completely non-intrusive for residents. Most tests in Wildwood Crest, NJ take around 30 to 60 minutes, but the efficiency and comfort improvements can last for many years.

How to Measure Duct Leakage

Duct leakage is defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to measure tiny pressure differences, making it possible to determine how much air the ducts are losing. Understanding this number helps you detect issues, explore potential fixes, and determine if your home aligns with local energy code requirements in Wildwood Crest, NJ.

Cost of Excessive Duct Leakage

If you’re seeing higher energy bills, irregular heating or cooling, or frequent HVAC malfunctions, duct leakage may be at fault. According to ENERGY STAR, the average household loses 20%–30% of conditioned air because of leaking ducts. When outdoor temperatures enter your system, the HVAC must work harder to compensate, resulting in higher energy costs and reduced comfort.

Overworked equipment also heightens the chance of system failures and expensive repairs. Proper duct sealing helps sustain your HVAC system’s long-term condition, increasing its operational lifespan and decreasing maintenance requirements.

Duct leaks can also draw in dust, mold spores, unwanted moisture, and other harmful contaminants. 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 ensures that new homes are built with duct systems sealed entirely using efficient materials such as mastic, foil tape, and insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. To apply this method, every vent is sealed aside from one access point. The HVAC system is isolated, and a machine is connected to the ducts. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method performs well for small and medium leaks. However, larger openings typically require manual sealing with mastic and tape. Technicians run a duct leakage test before and after aerosol sealing to quantify the reduction in leakage and verify the success of the process.

Common Areas of Duct Leakage

The most common spot where air escapes in duct systems is the joints. Ductwork features several metal pieces pressed together using tight fittings and metal bands, though these areas are seldom airtight.

As your HVAC system transitions between warm and cool air throughout the year, the ducts expand and contract. Over time, this movement makes the joints loosen, forming gaps and leaks — meaning a duct leakage test is advised for both new and older homes in Wildwood Crest, 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 is unsealed with mastic and approved tape, air leakage is almost certainly occurring.

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

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

If your home in Wildwood Crest, NJ does not meet duct leakage standards, you are likely overpaying for heating and cooling — and adding unnecessary strain to your HVAC equipment. Meeting the 3–4 CFM requirement matters not only for code compliance, but also for protecting your home’s comfort and reducing energy waste.

Your technician will also provide expert strategies to address leakage concerns, helping you achieve a passing score, bring down utility bills, and boost home efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins by closing off every duct and register with duct mask tape across both the supply and return sides.

After the registers are sealed, we attach the duct tester to either the unit itself or a main return.

The ducts are then depressurized to 25 Pascals. With this pressure applied, we use the nanometer to measure how much leakage is present.
