Confirm your HVAC system’s efficiency and meet local inspection standards with professional duct leakage test in West Wildwood, 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 West Wildwood, NJ

States and municipalities now follow the 2015 IECC, International Energy Conservation Code for single-family residences, as well as the 2018 International Energy Conservation Code for multi-family structures. The change will create several important implications for home builders and HVAC contractors operating within the state. A Duct Leakage Test and a mandatory Blower Door Test are now required for all new construction or remodeled homes under the 2015 regulatory standards. 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 raise utility expenses, overburden your HVAC system, and push insulation material and dust through every area of 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 set up a duct leakage test in West Wildwood, NJ, the technician begins by sealing all supply and return registers, leaving only the air handler or main return open. 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 teams up with a precision pressure sensor to measure airflow accurately and locate duct leaks without affecting your home. A duct leakage test — also referred to as a duct blaster test — highlights where air is leaking from your ducts to help you choose the proper sealing method.

duct leakage test is quick, low-impact, and does not disturb residents. Most tests in West Wildwood, NJ take between 30 and 60 minutes, and the improvements they deliver can elevate comfort and efficiency for years ahead.

How to Measure Duct Leakage

Duct leakage is tracked in cubic feet per minute (CFM) per 100 square feet of conditioned living area. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number enables you to recognize problem areas, consider efficiency improvements, and verify that your home meets local energy code requirements in West Wildwood, NJ.

Cost of Excessive Duct Leakage

If you’re dealing with rising utility bills, inconsistent room temperatures, or repeated HVAC issues, duct leakage could be the reason. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. Air entering from outside—whether warm or cold—makes your HVAC operate harder, causing energy costs to climb and comfort to decrease.

Overworked equipment also produces more frequent issues that require costly repairs. Proper duct sealing helps strengthen the long-term function of your HVAC system, improving its lifespan and reducing ongoing maintenance costs.

Duct leaks can also allow the entry of dust, mold spores, moisture, and a range of 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 instructs that new homes incorporate fully sealed duct systems using high-efficiency materials, including mastic, foil tape, and insulation. But what about leaks that lie far within enclosed wall or ceiling spaces?

Aerosol sealing technology (AeroSeal) offers a method to access hidden leaks deep within ductwork. To perform the technique, all vents are sealed except a single access opening. The HVAC system is isolated, and a machine is hooked into the duct system. It pressurizes the ducts and releases a delicate aerosol sealant that settles into small gaps and holes traditional techniques can’t access.

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians carry out leakage testing prior to and after aerosol sealing to observe the reduction and ensure treatment success.

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 moves through annual heating and cooling cycles, the ductwork expands and then contracts. Over time, this movement causes joints to lose their seal, creating gaps and leaks — making a duct leakage test valuable for any home in West Wildwood, NJ, whether new or old.

Many energy auditors check for leaks by feeling along the ductwork and using a small tool to gauge the size of gaps 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 should measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler installed. For new construction, obtaining an occupancy certificate requires passing a duct leakage test first.

If your home in West Wildwood, NJ cannot achieve a passing duct leakage score, you are likely wasting money on heating and cooling — and increasing wear on your HVAC system over time. Meeting the 3–4 CFM requirement is significant not only for meeting local code but also for maintaining optimal comfort and efficiency in your home.

Your technician will also offer expert guidance on fixing leakage problems so you can earn a passing score, reduce utility costs, and enhance your home’s overall performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by blocking all ducts and registers with duct mask tape across both 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 to a depressurized pressure of 25 Pascals. Once depressurized, we use the nanometer for a leakage reading.
