Duct Leakage Test in Pine Valley borough, NJ

Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in Pine Valley borough, NJ. Our certified technicians locate and assess air leaks in ductwork to help homeowners and builders improve comfort, reduce energy consumption, and comply with state regulations.

Why Duct Leakage Test is Important In Pine Valley borough, NJ

In most states and municipalities, the 2015 IECC, International Energy Conservation Code is required for single-family homes, while the 2018 International Energy Conservation Code is required for multi-family homes. The change will create considerable implications for home builders and HVAC contractors carrying out projects in the state. A Duct Leakage Test as well as the required Blower Door Test must now be performed on new or remodeled homes following 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 cause your energy bills to rise, strain your HVAC system, and move dust and insulation around your living spaces. 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 begin the process of a duct leakage test in Pine Valley borough, NJ, your technician seals off all supply and return registers apart from the main return or air handler. A specially calibrated fan known as a duct blaster is then put in place at the opening. It depressurizes the ductwork so escaping air can be accurately identified.

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 — sometimes identified as a duct blaster test — shows where your ducts lose air, helping you plan the right sealing approach.

duct leakage test is rapid, clean, and performed without inconvenience to residents. Most tests in Pine Valley borough, NJ take only 30 to 60 minutes, yet the comfort and efficiency gains can last for years.

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 locate trouble spots, review possible upgrades, and see if your home complies with local energy code requirements in Pine Valley borough, NJ.

Cost of Excessive Duct Leakage

If you’re facing higher energy bills, uneven heating or cooling, or recurring HVAC repairs, duct leakage could be to blame. According to ENERGY STAR, homes across the country lose 20% to 30% of their conditioned air through duct leakage. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps maintain the long-term health of your HVAC system, extending its lifespan and reducing ongoing maintenance needs.

Duct leaks can also cause dust, mold spores, and excess moisture — along with other contaminants — to infiltrate the duct system. This can aggravate allergies, lower indoor air quality, and eventually lead to costly structural damage hidden 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 if some leaks are hidden within the depths of your walls or ceilings?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. 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 emits a fine aerosol sealant that fills tiny gaps and holes that standard sealing methods 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 complete a duct leakage test before and after aerosol sealing to track leakage reduction and confirm the treatment’s success.

Common Areas of Duct Leakage

The most frequent area where ducts lose air is at the joints. Ductwork consists of several metal sections pressed together with tight fittings and metal bands, yet these connections are almost never fully airtight.

As your HVAC system heats and cools throughout the year, the ducts expand and contract. Over time, this movement weakens joint connections, producing gaps and leaks — making duct leakage test essential for both new and older homes in Pine Valley borough, 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 has not received sealing with mastic and approved tape, leakage is very probable.

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

To achieve a passing duct leakage result, your system must read under 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, a passing duct leakage test is mandatory before a home can be granted an occupancy certificate.

If your home in Pine Valley borough, 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 vital not only for satisfying code rules but also for preserving your home’s comfort and energy performance.

Your technician will also provide skilled recommendations to resolve leakage problems so you can reach a passing score, decrease energy costs, and improve home performance.

Local Energy Audits — affordable duct leakage test in Pine Valley borough, NJ

Local Energy Audits is proud to serve families and builders across Pine Valley borough, NJ and the surrounding local areas. We specialize in assessing duct leakage and energy inefficiencies with blower door tests and duct leakage tests. Whether it’s a new build or a current home, we’re here to support you.

The Duct Leakage Test Steps Explained

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

After the registers are sealed, we install the duct tester on the unit or on a main return.

The ducts are then reduced to a depressurized state of 25 Pascals. With them depressurized, the nanometer gives us the duct leakage reading.
