Duct Leakage Test in Pine Valley, NJ

Verify your HVAC system’s efficiency and meet local requirements with reliable duct leakage test in Pine Valley, 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 Pine Valley, 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 result in significant implications for home builders and HVAC contractors doing business in the state. A Duct Leakage Test as well as a Blower Door Test in newly constructed or remodeled homes is now required in accordance with the 2015 regulations. Did you know that ducts are a significant source of air leakage in residential properties across Pennsylvania, New Jersey, and Delaware? Leaked air can lead to rising energy bills, added strain on your HVAC system, and unwanted insulation and dust spreading through 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 Pine Valley, NJ, the technician begins by sealing all supply and return registers, leaving only the air handler or main return open. A duct blaster — a specially calibrated fan — is then connected to the opening. It depressurizes the duct system to expose areas where air is leaking.

The duct blaster uses its precision pressure sensor partner to measure airflow and uncover duct leaks without causing any home disruption. A duct leakage test — sometimes referred to as a duct blaster test — uncovers air leaks in your ductwork so you can determine the ideal sealing approach.

duct leakage test is fast, debris-free, and completely resident-friendly. Most tests in Pine Valley, NJ are done within 30 to 60 minutes, with improvements that strengthen comfort and efficiency for years to come.

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 evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number helps you detect issues, explore potential fixes, and determine if your home aligns with local energy code requirements in Pine Valley, 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, a large portion of homes lose between 20% and 30% of conditioned air due to leaky ducts. Hot or cold outside air leaking in makes your HVAC system work more than it should, driving up energy costs and diminishing comfort.

Overworked equipment also makes breakdowns more common and repairs more expensive. Proper duct sealing helps support the long-term durability of your HVAC system, lengthening its lifespan and minimizing ongoing maintenance demands.

Duct leaks can also bring dust, mold spores, excess moisture, and other impurities into the duct system. This can worsen allergy reactions, negatively affect indoor air quality, and contribute to costly hidden structural damage over the years.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates that new homes include fully sealed duct systems built with 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) provides a way to seal concealed openings inside the duct system. To use this method, technicians seal all vents except one access point. The HVAC system is isolated, and a machine is hooked up to the duct system. It pressurizes the ducts and distributes an ultra-fine aerosol sealant to fill small gaps and holes that manual 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 usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system cycles through heating and cooling each year, the ducts naturally expand and contract. Over time, this movement causes the joints to loosen, creating gaps and leaks — which is why a duct leakage test is recommended for both new and older homes in Pine Valley, NJ.

Many energy auditors identify duct leakage by moving their hands along the ducts and using a small tool to check the width of joint openings. If your duct system does not include sealing with mastic and approved tape, leakage is highly likely.

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

To achieve a passing duct leakage result, your system has to measure below 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, an occupancy certificate cannot be issued unless the home passes a duct leakage test.

If your home in Pine Valley, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. Meeting the 3–4 CFM requirement is crucial not only for passing code but also for maintaining your home’s overall energy efficiency and comfort.

Your technician will also provide professional insights on resolving leakage issues so you can achieve a passing score, lower your utility costs, and optimize home performance.

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 connect the duct tester to either the main HVAC unit or its primary return.

The ducts are then depressurized to a level of 25 Pascals. Once depressurized, the nanometer provides an accurate duct leakage reading.
