Duct Leakage Test in Pine Forge, PA

Verify your HVAC system’s efficiency and meet local requirements with reliable duct leakage test in Pine Forge, PA. Our certified technicians locate and assess air leaks in ductwork to help homeowners and builders improve comfort, reduce energy consumption, and comply with state regulations.

Why Duct Leakage Test is Important In Pine Forge, PA

Across the country, states and municipalities enforce the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will bring forward important implications for home builders and HVAC contractors working in the state. A Duct Leakage Test and the mandated Blower Door Test apply to all new or renovated homes under the 2015 regulations. Did you know that ducts are responsible for a large share of air leakage issues in homes in 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 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 begin the process of a duct leakage test in Pine Forge, PA, your technician seals off all supply and return registers apart from the main return or air handler. A duct blaster fan, carefully calibrated for accuracy, is then attached to the duct opening. It depressurizes the ductwork, allowing leaks to become more noticeable.

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 easy, clean, and unobtrusive for residents in the home. Most tests in Pine Forge, PA are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

How to Measure Duct Leakage

Duct leakage is defined in cubic feet per minute (CFM) per 100 square feet of conditioned space within the structure. Your technician uses a nanometer to detect minimal pressure variations, revealing the amount of air leakage occurring in 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 Pine Forge, PA.

Cost of Excessive Duct Leakage

If you are experiencing high utility bills, uneven temperatures, or frequent HVAC repairs, duct leakage may be the cause. According to ENERGY STAR, the average duct system loses between 20% and 30% of its conditioned air due to leaks. Hot or cold outside air entering your system forces your HVAC system to work harder, driving up energy costs and reducing comfort.

Overworked equipment also causes components to fail more often, leading to costly repairs. 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 permit dust, mold spores, extra moisture, and other airborne contaminants into 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 instructs that new homes incorporate fully sealed duct systems using high-efficiency materials, including mastic, foil tape, and insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) can identify and seal leaks that lie deep inside ductwork. To perform the technique, all vents are sealed except a single access opening. The HVAC system is isolated, and a machine is hooked into the duct system. It pressurizes the ducts and sprays a fine mist of sealant that fills tiny leaks and holes beyond the reach of conventional sealing.

This method is great for handling small to medium leaks. However, larger holes often require manual sealing with mastic and tape. Technicians complete before-and-after duct leakage tests to measure leakage reduction and ensure the aerosol sealing was effective.

Common Areas of Duct Leakage

The most typical place for ducts to lose air is at the joints. Ductwork consists of different metal sections pressed together with tight fittings and metal bands, yet these joints are not usually airtight.

As your HVAC system shifts between hot and cold cycles all year long, the ductwork expands and contracts. Over time, this movement loosens the joints, causing gaps and leaks — which is why both new and older homes in Pine Forge, PA should consider a duct leakage test.

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 has not been sealed with mastic and approved tape, there is a high chance that leakage is occurring.

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

To achieve a passing duct leakage result, your system has to measure below 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, passing the duct leakage test is a necessary step before securing an occupancy certificate.

If your home in Pine Forge, PA does not meet duct leakage standards, you are likely overpaying for heating and cooling — and adding unnecessary strain to your HVAC equipment. Meeting the 3–4 CFM requirement is critical not just for code compliance, but also for defending your home’s comfort and energy performance.

Your technician will also offer professional recommendations to tackle leakage issues so you can secure a passing score, reduce utility costs, and strengthen home performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with sealing each duct and register using duct mask tape on the supply and return sides.

After the registers are sealed, we set up the duct tester by attaching it to the unit or 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.
