Duct Leakage Test in Silverdale, PA

Ensure proper HVAC performance and code compliance by scheduling professional duct leakage test in Silverdale, PA. Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders improve comfort, reduce energy waste, and achieve compliance with state requirements.

Why Duct Leakage Test is Important In Silverdale, 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 have some significant implications for home builders and HVAC contractors operating in the state. A Duct Leakage Test as well as a Blower Door Test in newly constructed or remodeled homes is now required in accordance with the 2015 regulations. 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 essential part of maintaining both new and older homes. Keep reading to discover why duct leakage test is important and how it can support your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start conducting a duct leakage test in Silverdale, PA, the technician seals all supply and return registers other than the main return or the air handler. A specially calibrated duct blaster fan is then secured to the opening. Its job is to depressurize the duct system, allowing air leaks to reveal themselves clearly.

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 — detects air loss in the duct system, allowing you to apply the most suitable sealing solutions.

duct leakage test is quick, low-impact, and does not disturb residents. Most tests in Silverdale, 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 monitored in cubic feet per minute (CFM) per 100 square feet of the conditioned sections of the home. Your technician uses a nanometer to measure tiny pressure changes, revealing how much air is escaping through the ducts. Understanding this number lets you identify inefficiencies, weigh improvement options, and confirm your home’s compliance with local energy code requirements in Silverdale, PA.

Cost of Excessive Duct Leakage

If your utility bills keep climbing, temperatures vary from room to room, or your HVAC needs constant fixing, duct leakage may be the cause. According to ENERGY STAR, homes with leaky ducts routinely lose 20% to 30% of conditioned air. Air entering from outside—whether warm or cold—makes your HVAC operate harder, causing energy costs to climb and comfort to decrease.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. Proper duct sealing helps support your HVAC system’s long-term operation, increasing its lifespan and lowering frequent maintenance needs.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. This can make allergies worse, impact indoor air quality, and result in costly structural damage behind walls or ceilings as time passes.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to have fully sealed duct systems using modern, energy-efficient materials such as mastic, foil tape, and insulation. But what about leaks that lie far within enclosed wall or ceiling spaces?

Aerosol sealing technology (AeroSeal) reaches interior duct leaks that traditional sealing methods can’t access. To complete this method, all vents are closed off except for one access opening. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and distributes an ultra-fine aerosol sealant to fill small gaps and holes that manual sealing methods can’t access.

This method works best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians do a duct leakage test before and after aerosol sealing to calculate how much leakage has been reduced and validate the results.

Common Areas of Duct Leakage

The most common location for air leakage in ducts is the joints. Ductwork includes several metal sections pressed together with tight fittings and metal bands, but those connections are almost never airtight.

As your HVAC system operates in varying temperatures across the year, the ducts undergo expansion and contraction. Over time, this movement loosens the joints, causing gaps and leaks — which is why both new and older homes in Silverdale, PA should consider a duct leakage test.

Many energy auditors evaluate duct leakage by feeling around the duct system and using a small tool to check the size of joint gaps. 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 read under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler. For new construction, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Silverdale, PA falls short in a duct leakage test, you are probably paying extra for heating and cooling — and placing lasting pressure on your HVAC equipment. Meeting the 3–4 CFM requirement is key not only for staying code-compliant but for maintaining energy efficiency and consistent comfort 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 by securing duct mask tape over every duct and register on the supply and return sides.

After the registers are sealed, we attach our duct tester to the system’s unit or to the main return.

The ducts are then taken down to 25 Pascals. With the ducts depressurized, the nanometer is used to determine the leakage level.
