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 Jackson township, 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 present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test along with a Blower Door Test is now required for any newly constructed or remodeled home as outlined in the 2015 regulations. Did you know that leaking ducts are a widespread cause of air loss 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 valuable for new and existing homes alike. Read on to learn why duct leakage test is important and how it can help you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start a duct leakage test in Jackson township, NJ, the technician will close and seal every supply and return register except the main return or air handler. A specially calibrated fan, known as a duct blaster, is then attached to the opening. The purpose of this fan is to depressurize the duct system, creating the ideal conditions to identify where air is escaping.

The duct blaster system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. A duct leakage test — often described as a duct blaster test — identifies leaking areas in your ducts so you can determine the most efficient sealing fix.

duct leakage test is simple, clean, and minimally invasive for residents. Most tests in Jackson township, NJ are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

How to Measure Duct Leakage

Duct leakage is quantified in cubic feet per minute (CFM) for each 100 square feet of conditioned living space. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number allows you to pinpoint problem areas, assess needed improvements, and confirm whether your home satisfies local energy code requirements in Jackson township, 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, most households lose 20% to 30% of their heated or cooled air because of duct leaks. 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 leads to recurring breakdowns and higher repair expenses. Proper duct sealing helps protect the long-term performance of your HVAC system, increasing its lifespan and lowering future maintenance requirements.

Duct leaks can also introduce dust, mold spores, moisture, and additional contaminants into the duct system. This can intensify allergy symptoms, harm indoor air quality, and cause long-term structural damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to have fully sealed duct systems using modern, energy-efficient materials such as mastic, foil tape, and insulation. But what should you do when leaks are located deep within your walls or ceilings?

Aerosol sealing technology (AeroSeal) is an effective solution for reaching hidden ductwork leaks. 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 applies a fine aerosol sealant that fills tiny openings where standard sealing cannot reach.

This method is great for handling small to medium leaks. However, larger holes often require manual sealing with mastic and tape. Technicians perform a duct leakage test both before and after aerosol sealing to determine how much leakage has decreased and confirm the treatment worked.

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 warms and cools over the seasons, the ductwork expands and then contracts. 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 Jackson township, NJ.

Many energy auditors locate duct leakage by touching the ductwork and using a small tool to measure the width of separation 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 should measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler installed. For new construction, a passing duct leakage test is a required step before final occupancy certification can be awarded.

If your home in Jackson township, 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 key not only for staying code-compliant but for maintaining energy efficiency and consistent comfort in your home.

Your technician will also recommend effective ways to fix leakage issues so you can earn a passing score, save on utilities, and improve home performance.

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 to either the unit itself or a main return.

The ducts are then brought to a depressurized pressure of 25 Pascals. Once depressurized, we use the nanometer for a leakage reading.
