Why Duct Leakage Test is Important In Kulpsville, PA

In most states and municipalities, the 2015 IECC, International Energy Conservation Code is required for single-family homes, while the 2018 International Energy Conservation Code is required for multi-family homes. The change will create considerable implications for home builders and HVAC contractors carrying out projects in 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 duct leakage is one of the most common issues affecting homes in Pennsylvania, New Jersey, and Delaware? Leaked air can escalate your energy costs, force your HVAC system to work harder, and move insulation and dust throughout your house. This makes duct leakage test crucial for new and old homes alike. Keep reading to learn why duct leakage test is important and how you can benefit from them.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Kulpsville, PA, your technician seals all supply and return registers, leaving only the main return or air handler open. A specially calibrated duct blaster fan is then connected to the opening. This fan depressurizes the ducts to help locate where air is escaping.

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 simple, clean, and minimally invasive for residents. Most tests in Kulpsville, PA require only 30 to 60 minutes, yet the upgrades can improve your home’s comfort and efficiency well into the future.

How to Measure Duct Leakage

Duct leakage is measured in cubic feet per minute (CFM) per 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 recognize where issues exist, plan meaningful improvements, and check your home against local energy code requirements in Kulpsville, PA.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, most homes lose 20% to 30% of their conditioned air through leaking ductwork. When hot or cold outside air enters your system, your HVAC has to work harder, increasing energy costs and lowering overall comfort.

Overworked equipment also leads to more breakdowns and costly repairs. Proper duct sealing helps improve the long-term health of your HVAC system, boosting longevity and reducing ongoing maintenance requirements.

Duct leaks can also pull in dust, mold spores, moisture, and numerous 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 requires new homes to use fully sealed duct systems crafted from up-to-date, efficient materials such as 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) is designed to reach and seal hidden gaps throughout the duct system. 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 sends a fine aerosol sealant through the system, closing small gaps that normal sealing approaches can’t reach.

This method works efficiently for small to medium leaks. However, larger gaps usually require manual sealing using mastic and tape. Technicians perform a duct leakage test both before and after aerosol sealing to determine how much leakage has decreased and confirm the treatment worked.

Common Areas of Duct Leakage

The most common spot where air escapes in duct systems is the joints. Ductwork features several metal pieces pressed together using tight fittings and metal bands, though these areas are seldom airtight.

As your HVAC system moves through annual heating and cooling cycles, the ductwork expands and then contracts. 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 Kulpsville, 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 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 needs to measure under 4 CFM per 100 square feet when the air handler is included, or 3 CFM per 100 square feet when it is not. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Kulpsville, PA does not meet the duct leakage requirement, you’re likely paying elevated heating and cooling costs — and overburdening your HVAC system. Meeting the 3–4 CFM requirement is vital not only for satisfying code rules but also for preserving your home’s comfort and energy performance.

Your technician will also give professional advice on resolving leakage issues to help you achieve a passing score, cut down utility bills, and boost your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by taping off all ducts and registers with duct mask tape on the supply and return sides.

After the registers are sealed, we attach the duct tester directly to the unit or to one primary return.

The ducts are then pulled down to 25 Pascals of depressurization. With the ducts in this state, we take a leakage reading using the nanometer.
