Why Duct Leakage Test is Important In Pomeroy, PA

States and municipalities have put in place the 2015 IECC, International Energy Conservation Code for single-family projects and the 2018 International Energy Conservation Code for multi-family projects. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test paired with a Blower Door Test is now expected for newly constructed and remodeled homes in accordance with the 2015 code requirements. Did you know that improperly sealed ducts account for a major portion of air leakage in homes 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 beneficial for all homes, new or old. Keep reading to find out why duct leakage test is essential and how it can improve your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin performing a duct leakage test in Pomeroy, PA, your technician closes off all supply and return registers except the main return or air handler system. A duct blaster — a precision-calibrated fan — is then fitted to the duct opening. By depressurizing the system, it makes all air leaks much easier to detect.

The duct blaster uses a precision pressure sensor to monitor airflow and pinpoint leaks throughout the ductwork without interrupting your home environment. A duct leakage test — sometimes called a duct blaster test — detects air loss in the duct system, allowing you to apply the most suitable sealing solutions.

duct leakage test is fast, tidy, and causes no disruption for residents. Most tests in Pomeroy, PA are done in about 30 to 60 minutes, and the resulting enhancements can support your home’s comfort and efficiency for many years.

How to Measure Duct Leakage

Duct leakage is calculated in cubic feet per minute (CFM) for every 100 square feet of conditioned space. Your technician uses a nanometer to detect small pressure differences, which indicate how much air is leaking through the ducts. Understanding this number allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Pomeroy, PA.

Cost of Excessive Duct Leakage

If you’re struggling with expensive utility bills, inconsistent indoor temperatures, or continual HVAC problems, duct leakage might be the culprit. According to ENERGY STAR, an average home’s ductwork loses 20% to 30% of conditioned air through leaks. Hot or cold outside air creeping into your system forces the HVAC to work inefficiently, increasing energy spending and reducing comfort.

Overworked equipment also creates more wear, leading to breakdowns and costly fixes. Proper duct sealing helps enhance the long-term resilience of your HVAC system, lengthening its lifespan and cutting overall maintenance needs.

Duct leaks can also pull dust, mold spores, excess moisture, and various contaminants into the duct system. This can escalate allergies, lower the overall air quality indoors, and lead to costly damage behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC specifies that newly constructed homes must use fully sealed duct systems with modern, efficient materials such as mastic, foil tape, and insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) is an effective solution for reaching hidden ductwork leaks. To carry out this method, every vent is sealed except a single access point. The HVAC system is separated, and a machine is attached 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 is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. 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 leakage area in duct systems is the joints. Ductwork involves numerous metal parts pressed together with tight fittings and metal bands, but these connections are almost never fully airtight.

As your HVAC system operates in varying temperatures across the year, the ducts undergo expansion and contraction. 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 Pomeroy, PA.

Many energy auditors examine duct leakage by touching the ducts and using a small tool to measure the gap width between joints. If your duct system lacks sealing with mastic and approved tape, there is a strong chance that leakage is present.

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

To achieve a passing duct leakage result, your system must come in under 4 CFM per 100 square feet with the air handler, or 3 CFM per 100 square feet when the air handler is removed. For new construction, a passing duct leakage test is a required step before final occupancy certification can be awarded.

If your home in Pomeroy, PA doesn’t achieve a passing duct leakage score, you’re likely overspending on heating and cooling — and putting extended strain on your HVAC unit. 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 offer expert guidance on fixing leakage problems so you can earn a passing score, reduce utility costs, and enhance your home’s overall performance.

The Duct Leakage Test Steps Explained

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

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

The ducts are then lowered to a depressurized level of 25 Pascals. With the system at that pressure, the nanometer is used to read the duct leakage.
