Duct Leakage Test in Washington borough, NJ

Guarantee your HVAC system runs efficiently and adheres to local requirements with quality duct leakage test in Washington borough, NJ. Our certified technicians locate and quantify air leaks in duct systems so homeowners and builders can enhance comfort, lower energy loss, and comply with state regulations.

Why Duct Leakage Test is Important In Washington borough, NJ

Various states and municipalities have adopted the 2015 IECC, International Energy Conservation Code for single-family houses, along with the 2018 International Energy Conservation Code for multi-family units. The change will set in motion important implications for home builders and HVAC contractors who operate in 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 duct systems contribute heavily to air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can escalate your energy costs, force your HVAC system to work harder, and move insulation and dust throughout your house. This makes duct leakage test essential for both new and older homes. Continue reading to understand why duct leakage test matters and how it can benefit you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To commence a duct leakage test in Washington borough, NJ, your technician will seal every supply and return register except the primary 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 joins forces with a precision pressure sensor to monitor airflow and pinpoint leak points in the ducts without disturbing your home. A duct leakage test — also known as a duct blaster test — pinpoints where air is escaping from your ducts, helping you choose the best sealing methods.

duct leakage test is efficient, clean, and performed without bothering residents. Most tests in Washington borough, NJ are completed in just 30 to 60 minutes, while the benefits to comfort and efficiency can last long-term.

How to Measure Duct Leakage

Duct leakage is assessed using cubic feet per minute (CFM) per 100 square feet of conditioned space. 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 inefficiencies, assess needed upgrades, and ensure your home complies with local energy code requirements in Washington borough, NJ.

Cost of Excessive Duct Leakage

If you’re struggling with expensive utility bills, inconsistent indoor temperatures, or continual HVAC problems, duct leakage might be the culprit. According to ENERGY STAR, many homes lose as much as 20% to 30% of conditioned air through duct leaks. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also produces more frequent issues that require costly repairs. Proper duct sealing helps promote the long-term integrity of your HVAC system, extending its lifespan and limiting continued maintenance needs.

Duct leaks can also enable dust, mold spores, elevated moisture, and unwanted contaminants to infiltrate the duct system. This can negatively influence allergies, weaken indoor air quality, and lead to expensive long-term damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates fully sealed duct systems in new homes, made from energy-efficient materials like mastic, foil tape, and proper insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) enables effective sealing of leaks hidden inside ducts. To complete this method, all vents are closed off except for one access opening. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with mastic and tape. Technicians conduct a duct leakage test before and after aerosol sealing to measure how much the leakage has been reduced and ensure the treatment is successful.

Common Areas of Duct Leakage

The most typical place for ducts to lose air is at the joints. Ductwork consists of different metal sections pressed together with tight fittings and metal bands, yet these joints are not usually airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly 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 Washington borough, 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 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 passing duct leakage test is a required step before final occupancy certification can be awarded.

If your home in Washington borough, NJ does not meet the duct leakage requirement, you’re likely paying elevated heating and cooling costs — and overburdening your HVAC system. Meeting the 3–4 CFM requirement is essential not only for code compliance but also for protecting your home’s energy efficiency and comfort.

Your technician will also share expert solutions for tackling leakage problems so you can pass the test, cut down utility expenses, and improve overall comfort and efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins with the technician sealing all ducts and registers using duct mask tape across the supply and return sides.

After the registers are sealed, we connect the duct tester to either the main HVAC unit or its primary return.

The ducts are then depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
