Duct Leakage Test in Parker Ford, PA

Ensure your HVAC system is sealed, efficient, and fully compliant with local regulations through duct leakage test in Parker Ford, PA. 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 Parker Ford, PA

States and municipalities have adopted 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 present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test plus the required Blower Door Test are now necessary for newly built or remodeled homes in line with the 2015 regulations. Did you know that ducts are a leading factor in home air leakage across Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. This makes duct leakage test essential for both new and older homes.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start the duct testing process in Parker Ford, PA, the technician seals all supply and return registers except for the main return or the air handler. A specially calibrated fan called a duct blaster is then connected to the opening. This fan depressurizes the duct system, making it easier to pinpoint exactly where air is leaking.

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 — often known as a duct blaster test — exposes duct air loss, allowing you to apply the most effective sealing techniques.

duct leakage test is hassle-free, clean, and won’t interfere with residents’ daily routines. Most tests in Parker Ford, PA 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 expressed in cubic feet per minute (CFM) per 100 square feet of the home’s conditioned area. Your technician uses a nanometer to detect pressure variations, helping quantify the amount of duct leakage. Understanding this number gives you insight into problem areas, helps you plan improvements, and ensures your home meets local energy code requirements in Parker Ford, PA.

Cost of Excessive Duct Leakage

If you’re dealing with rising utility bills, inconsistent room temperatures, or repeated HVAC issues, duct leakage could be the reason. According to ENERGY STAR, leaking ducts cause the average home to lose 20%–30% of conditioned air. Air from outside—whether hot or cold—entering your system forces your HVAC to work harder, increasing utility bills and reducing indoor comfort.

Overworked equipment also creates more wear, leading to breakdowns and costly fixes. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter the duct system. This can make allergies more severe, reduce the quality of indoor air, and produce costly structural harm behind walls or ceilings as time progresses.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires all newly constructed homes to have fully sealed ductwork with modern, energy-saving materials such as mastic, foil tape, and insulation. But what if those leaks are tucked away behind walls or ceilings?

Aerosol sealing technology (AeroSeal) enables effective sealing of leaks hidden inside ducts. To implement this method, every vent is covered except one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method handles small to medium leaks very effectively. However, large openings may still require traditional mastic and tape sealing. Technicians run leakage tests both before and after aerosol sealing to gauge how much air loss decreased and confirm proper results.

Common Areas of Duct Leakage

The most common area where ducts leak air is around the joints. Ductwork uses several metal parts pressed together with tight fittings and metal bands, though these points are rarely airtight.

As your HVAC system warms and cools over the seasons, the ductwork expands and then contracts. Over time, this movement gradually loosens the joints, creating leaks and gaps — highlighting the importance of duct leakage test in both new and older homes in Parker Ford, PA.

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 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 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 duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Parker Ford, PA 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 give expert suggestions on correcting leakage issues, allowing you to pass the test, lower utility expenses, and improve your home’s overall efficiency.

The Duct Leakage Test Steps Explained

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

After the registers are sealed, we fasten the duct tester to the unit or to a main return.

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
