Duct Leakage Test in Toughkenamon, PA

Make sure your HVAC system performs at its best and satisfies local energy standards with certified duct leakage test in Toughkenamon, PA. Our certified technicians identify and quantify air leaks in duct systems so homeowners and builders can optimize comfort, reduce energy waste, and meet state-level requirements.

Why Duct Leakage Test is Important In Toughkenamon, PA

Numerous states and municipalities rely on the 2015 IECC, International Energy Conservation Code for single-family properties and apply the 2018 International Energy Conservation Code to multi-family properties. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test and a mandatory Blower Door Test are now required for all new construction or remodeled homes under the 2015 regulatory standards. Did you know that ducts are a leading factor in home air leakage across 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 highly important for homes of any age. Read on to learn why duct leakage test matters and the benefits you can gain.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in Toughkenamon, PA, the technician seals all supply and return registers other than the main return or the air handler. A duct blaster, which is a specially calibrated fan, is then installed at the opening. The fan depressurizes the ducts, helping identify all points where air may be escaping.

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 swift, clean, and carried out with no disturbance to residents. Most tests in Toughkenamon, PA are completed in roughly 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency long-term.

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 detect small pressure differences, which indicate how much air is leaking through the ducts. Understanding this number helps you spot leakage issues, evaluate corrective measures, and determine if your home is meeting local energy code requirements in Toughkenamon, PA.

Cost of Excessive Duct Leakage

If you observe rising utility costs, temperature swings in different rooms, or regular HVAC breakdowns, duct leakage may be involved. According to ENERGY STAR, leaking ducts cause the average home to lose 20%–30% of conditioned air. 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 more breakdowns and costly repairs. 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 introduce dust, mold spores, moisture, and additional contaminants into the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC enforces that new homes incorporate fully sealed ducts made with modern, energy-efficient materials including mastic, foil tape, and insulation. But what do you do about leaks that sit deep within walls or ceilings?

Aerosol sealing technology (AeroSeal) provides a way to seal concealed openings inside the duct system. To begin this method, every vent is sealed except for one access opening. The HVAC unit is isolated, and a machine is installed onto the duct system. It pressurizes the ducts and emits a fine aerosolized sealant designed to fill small leaks unreachable with standard sealing.

This method is very effective for minor to moderate leaks. However, substantial openings may still need traditional sealing with mastic and tape. Technicians run a duct leakage test before and after aerosol sealing to quantify the reduction in leakage and verify the success of the process.

Common Areas of Duct Leakage

The most frequent source of duct air leakage is the joints. Ductwork uses many metal pieces pressed together with tight fittings and metal bands, but these joining points are rarely airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly expand and contract. Over time, this movement causes joints to lose their seal, creating gaps and leaks — making a duct leakage test valuable for any home in Toughkenamon, PA, whether new or old.

Many energy auditors check for leaks by feeling along the ductwork and using a small tool to gauge the size of gaps between joints. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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, a passing duct leakage test is essential before the home can qualify for an occupancy certificate.

If your home in Toughkenamon, PA does not meet duct leakage standards, you are likely overpaying for heating and cooling — and adding unnecessary strain to your HVAC equipment. Meeting the 3–4 CFM requirement is significant not only for meeting local code but also for maintaining optimal comfort and efficiency in your home.

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 duct mask tape being placed on all ducts and registers on both the supply and return sides.

After the registers are sealed, we secure the duct tester to the HVAC 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.
