Why Duct Leakage Test is Important In Kintnersville, PA

Many states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family properties and the 2018 International Energy Conservation Code for multi-family developments. The change will carry significant implications for home builders and HVAC contractors serving communities 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 ducts often contribute significantly to air leakage problems in homes throughout Pennsylvania, New Jersey, and Delaware? Leaked air can drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test an important requirement for homes regardless of age. Keep reading to understand why duct leakage test is necessary and how it can help you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in Kintnersville, PA, the technician seals all supply and return registers other than the main return or the air handler. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

The duct blaster, combined with a precision pressure sensor, measures airflow and detects leaks in the duct system without causing any disturbance 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 Kintnersville, PA are completed within 30 to 60 minutes, and the improvements can benefit your home’s comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is specified in cubic feet per minute (CFM) for each 100 square feet of conditioned space. 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 reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Kintnersville, PA.

Cost of Excessive Duct Leakage

If you’re encountering increased energy bills, temperature inconsistencies, or constant HVAC repairs, duct leakage could be the source. According to ENERGY STAR, a large portion of homes lose between 20% and 30% of conditioned air due to leaky ducts. Outside air that’s too hot or too cold entering your system strains your HVAC, resulting in higher energy consumption and less comfort.

Overworked equipment also creates more wear, leading to breakdowns and costly fixes. Proper duct sealing helps safeguard the long-term reliability of your HVAC system, extending its lifespan and reducing how often maintenance is needed.

Duct leaks can also enable dust, mold spores, elevated moisture, and unwanted contaminants to infiltrate the duct system. This can amplify allergy problems, impact air quality indoors, and slowly create costly structural damage behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires newly built homes to install fully sealed duct systems using advanced materials like mastic, foil tape, and quality 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 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 injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method handles small to medium leaks very effectively. However, large openings may still require traditional mastic and tape sealing. 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 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 adjusts temperatures throughout the year, the ducts go through expansion and contraction. Over time, this movement causes joints to lose their seal, creating gaps and leaks — making a duct leakage test valuable for any home in Kintnersville, PA, whether new or old.

Many energy auditors inspect duct leakage by feeling the ducts and using a small tool to determine how wide the gaps are between joints. If your duct system lacks proper sealing with mastic and approved tape, there is a high chance that leakage is taking place.

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 mandatory before a home can be granted an occupancy certificate.

If your home in Kintnersville, PA doesn’t pass its duct leakage evaluation, you’re likely paying more for temperature control — and contributing to long-term HVAC strain. Meeting the 3–4 CFM requirement matters not only for code compliance, but also for protecting your home’s comfort and reducing energy waste.

Your technician will also recommend effective ways to fix leakage issues so you can earn a passing score, save on utilities, and improve home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by securing duct mask tape over every duct and register on the supply and return sides.

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

The ducts are then depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
