Maintain top HVAC efficiency and stay aligned with local energy codes using trusted duct leakage test in Morris Plains, NJ. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Morris Plains, 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 create considerable implications for home builders and HVAC contractors carrying out projects 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 often contribute significantly to air leakage problems in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can spike your energy costs, wear down your HVAC system, and spread dust and insulation throughout various parts of your home. This makes duct leakage test necessary for homes of any age. Keep reading to discover why duct leakage test is so important and the advantages it offers.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To perform a duct leakage test in Morris Plains, NJ, the technician begins by sealing every supply and return register except for the primary return or air handler unit. A calibrated duct blaster is then secured to the opening. Its function is to depressurize the duct system, creating conditions that highlight any escaping air.

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 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 swift, clean, and carried out with no disturbance to residents. Most tests in Morris Plains, NJ take just 30 to 60 minutes, and the resulting improvements can enhance your home’s comfort and efficiency long-term.

How to Measure Duct Leakage

Duct leakage is measured using cubic feet per minute (CFM) per 100 square feet of conditioned floor area. Your technician uses a nanometer to capture subtle pressure changes, allowing accurate measurement of duct air leakage. Understanding this number helps you recognize where issues exist, plan meaningful improvements, and check your home against local energy code requirements in Morris Plains, NJ.

Cost of Excessive Duct Leakage

If you are experiencing high utility bills, uneven temperatures, or frequent HVAC repairs, duct leakage may be the cause. According to ENERGY STAR, homes with leaky ducts routinely lose 20% to 30% of conditioned air. When outside hot or cold air seeps into your system, your HVAC must compensate, leading to higher energy costs and diminished 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 introduce dust, mold spores, moisture, and additional contaminants into 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 outlines that new homes must be built with fully sealed duct systems, utilizing materials like mastic, foil tape, and insulation to enhance energy efficiency. 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 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 sends a fine aerosol sealant through the system, closing small gaps that normal sealing approaches can’t reach.

This method seals small to medium leaks effectively. However, large gaps may still call for manual sealing using 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 common point where ducts leak air is along the joints. Ductwork is made from multiple metal pieces pressed together with tight fittings and metal bands, but these connections are rarely completely airtight.

As your HVAC system cycles through heating and cooling each year, the ducts naturally expand and contract. Over time, this movement weakens the joints, creating gaps and leaks — a key reason duct leakage test is recommended for new and older homes in Morris Plains, NJ.

Many energy auditors evaluate duct leakage by feeling around the duct system and using a small tool to check the size of joint gaps. 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 must show under 4 CFM per 100 square feet if the air handler is installed, or 3 CFM per 100 square feet if it is not. For new construction, homes are required to pass a duct leakage test before an occupancy certificate can be issued.

If your home in Morris Plains, 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 important not only for the inspector, but also for maximizing energy efficiency and comfort in your home.

Your technician will also offer specialized recommendations to repair leakage issues so you can meet passing requirements, reduce utility bills, and improve your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with sealing each duct and register using duct mask tape on the supply and return sides.

After the registers are sealed, we attach our duct tester to the system’s unit or to the main return.

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