Duct Leakage Test in Camden city, NJ

Keep your HVAC system running at peak efficiency and in full compliance with local codes through expert duct leakage test in Camden city, NJ. Our certified technicians measure and identify ductwork air leaks, assisting homeowners and builders in boosting comfort, limiting energy waste, and maintaining state compliance.

Why Duct Leakage Test is Important In Camden city, NJ

Across the country, states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test along with the required Blower Door Test must now be conducted on any newly built or remodeled home as per 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 cause your energy bills to rise, strain your HVAC system, and move dust and insulation around your living spaces. 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 perform a duct leakage test in Camden city, NJ, the technician begins by sealing every supply and return register except for the primary return or air handler unit. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

The duct blaster pairs with a precision pressure sensor to measure airflow and identify leak locations in the ducts without disrupting 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, clean, and non-intrusive for residents. Most tests in Camden city, 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 rated in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned zone. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Camden city, NJ.

Cost of Excessive Duct Leakage

If high utility expenses, irregular temperatures, or repeated HVAC troubles sound familiar, duct leakage might be the root cause. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. If hot or cold air from outdoors enters your system, your HVAC works harder than necessary, causing energy costs to rise and comfort to fall.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps uphold the long-term performance of your HVAC system, stretching its lifespan and decreasing routine maintenance demands.

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter the duct system. This can trigger more severe allergies, diminish indoor air quality, and create expensive structural problems behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC states that new homes must have duct systems sealed completely with energy-efficient products such as mastic, foil tape, and insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) makes it possible to seal leaks found deep within the ductwork. To execute this method, all vents are sealed shut except a single access point. The HVAC system is isolated, and a machine is attached to the duct network. It pressurizes the ducts and emits a fine aerosol sealant that fills tiny gaps and holes that standard sealing methods can’t access.

This method is effective for addressing small to medium leaks. However, larger holes still need manual sealing 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 likely place for ducts to leak air is through their joints. Ductwork involves multiple metal pieces pressed together with secure fittings and metal bands, yet these connections are rarely perfectly airtight.

As your HVAC system operates in both heating and cooling modes year-round, the ducts continuously expand and contract. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Camden city, NJ, new or older, benefit from duct leakage test.

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 has not been sealed with mastic and approved tape, there is a high chance that leakage is occurring.

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

To achieve a passing duct leakage result, your system needs to register under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it attached. For new construction, obtaining an occupancy certificate requires passing a duct leakage test first.

If your home in Camden city, NJ cannot pass a duct leakage test, you are likely wasting money on heating and cooling — and causing long-term wear on your HVAC system. Meeting the 3–4 CFM requirement is indispensable not only for compliance purposes but for ensuring strong comfort and energy savings.

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 by ensuring all ducts and registers are sealed with duct mask tape on 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 set to a depressurized pressure of 25 Pascals. Once there, we use the nanometer to capture the leakage reading.
