Duct Leakage Test in Point Pleasant Beach, NJ

Protect system efficiency and meet local building codes by choosing certified duct leakage test in Point Pleasant Beach, NJ. Our certified technicians find and measure ductwork air leaks, allowing homeowners and builders to improve indoor comfort, reduce energy waste, and satisfy state standards.

Why Duct Leakage Test is Important In Point Pleasant Beach, 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 result in several substantial implications for home builders and HVAC contractors engaged in work across the state. A Duct Leakage Test and a Blower Door Test are now mandatory for newly built 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 raise utility expenses, overburden your HVAC system, and push insulation material and dust through every area of your home. This makes duct leakage test necessary for homeowners with either older or newly built homes. Read ahead to see why duct leakage test is important and what you gain from it.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start the duct testing process in Point Pleasant Beach, NJ, the technician seals all supply and return registers except for the main return or the 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 and its precision pressure sensor work together to measure airflow and detect duct leaks without causing any disruption in your home. 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 prompt, clean, and does not interrupt residents’ activities. Most tests in Point Pleasant Beach, NJ are completed in roughly 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is evaluated in cubic feet per minute (CFM) per 100 square feet of conditioned space inside the home. Your technician uses a nanometer to measure tiny pressure changes, revealing how much air is escaping through the ducts. Understanding this number allows you to identify concerns, evaluate upgrade opportunities, and determine whether your home fulfills local energy code requirements in Point Pleasant Beach, 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, duct leakage causes homeowners to lose 20%–30% of their conditioned air on average. When outdoor temperatures enter your system, the HVAC must work harder to compensate, resulting in higher energy costs and reduced comfort.

Overworked equipment also leads to more breakdowns and 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 let in dust, mold spores, added moisture, and other harmful contaminants. 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 that all new homes feature fully sealed duct systems utilizing updated, energy-efficient materials like mastic, foil tape, and 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 initiate this method, technicians seal every vent except one access point. The HVAC system is isolated, and a machine is connected to the ductwork. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method is effective for addressing small to medium leaks. However, larger holes still need manual sealing with mastic and tape. Technicians test the ducts for leakage before and after aerosol sealing to determine the reduction level and verify success.

Common Areas of Duct Leakage

The most common location for air leakage in ducts is the joints. Ductwork includes several metal sections pressed together with tight fittings and metal bands, but those connections are almost never airtight.

As your HVAC system runs through seasonal heating and cooling, the ducts experience ongoing expansion and contraction. 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 Point Pleasant Beach, NJ.

Many energy auditors check duct leakage by feeling around the ducts and using a small tool to test the width of gaps between joints. If your duct system was never sealed using mastic and approved tape, there is a high probability that air leakage is present.

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, you must pass a duct leakage test before the home can be approved for an occupancy certificate.

If your home in Point Pleasant Beach, 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 critical not just for code compliance, but also for defending 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 ducts and registers being sealed using duct mask tape on the supply and return sides.

After the registers are sealed, we attach our duct tester to the system’s unit or to the main return.

The ducts are then pulled down to 25 Pascals of depressurization. With the ducts in this state, we take a leakage reading using the nanometer.
