Why Duct Leakage Test is Important In Geigertown, PA

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 bring forward important implications for home builders and HVAC contractors working in the state. A Duct Leakage Test together with a Blower Door Test has become mandatory for any newly constructed or remodeled home under the 2015 code. Did you know that ductwork often causes some of the highest levels of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can push your energy bills higher, pressure your HVAC system, and spread dust and insulation inside your house. 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 initiate a duct leakage test in Geigertown, PA, your technician seals all supply and return registers, leaving only the main return or air handler open. A specially calibrated fan known as a duct blaster is then put in place at the opening. It depressurizes the ductwork so escaping air can be accurately identified.

The duct blaster pairs with a precision pressure sensor to measure airflow and identify leak locations in the ducts without disrupting your home. A duct leakage test — sometimes called a duct blaster test — reveals where your ducts are losing air so you can determine the most effective sealing solutions.

duct leakage test is hassle-free, clean, and won’t interfere with residents’ daily routines. Most tests in Geigertown, PA take 30 to 60 minutes to complete, and the benefits to comfort and efficiency can endure for years.

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 relies on a nanometer to read slight pressure variations that show the amount of air leaking through the duct system. Understanding this number helps you detect issues, explore potential fixes, and determine if your home aligns with local energy code requirements in Geigertown, PA.

Cost of Excessive Duct Leakage

If you’re seeing higher energy bills, irregular heating or cooling, or frequent HVAC malfunctions, duct leakage may be at fault. According to ENERGY STAR, the average household loses 20%–30% of conditioned air because of leaking ducts. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also results in more frequent breakdowns and expensive repair bills. Proper duct sealing helps preserve the long-term efficiency of your HVAC system, boosting its lifespan and cutting down on regular maintenance needs.

Duct leaks can also introduce dust, mold spores, moisture, and additional contaminants into the duct system. This can trigger more severe allergies, diminish indoor air quality, and create expensive structural problems behind walls or ceilings over time.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC sets a requirement that all new homes feature ducts sealed completely with modern materials like mastic, foil tape, and insulation. But what if the leaks you’re dealing with are deep inside the walls or ceilings?

Aerosol sealing technology (AeroSeal) helps seal hard-to-find openings within the duct system. To conduct this method, all vents are blocked except for one access point. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and sends out a fine aerosol mist that seals tiny openings traditional sealing cannot reach.

This method is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians carry out a duct leakage test before and after aerosol sealing to assess how much leakage has improved and ensure the treatment was effective.

Common Areas of Duct Leakage

The most likely place for ducts to leak air is through their joints. Ductwork involves multiple metal pieces pressed together with secure fittings and metal bands, yet these connections are rarely perfectly airtight.

As your HVAC system provides heating and cooling year-round, the ducts repeatedly expand and contract. Over time, this movement causes the joints to loosen, creating gaps and leaks — which is why a duct leakage test is recommended for both new and older homes in Geigertown, PA.

Many energy auditors identify duct leakage by moving their hands along the ducts and using a small tool to check the width of joint openings. 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 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, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Geigertown, PA fails its duct leakage test, you are likely facing inflated heating and cooling costs — along with increased strain on your HVAC system. Meeting the 3–4 CFM requirement is fundamental not only for code adherence but for boosting your home’s long-term 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 with duct mask tape being placed on all ducts and registers on both the supply and return sides.

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