Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in Geigertown, PA. Our certified technicians find and measure ductwork air leaks, allowing homeowners and builders to improve indoor comfort, reduce energy waste, and satisfy state standards.

Why Duct Leakage Test is Important In Geigertown, PA

States and municipalities have adopted 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 present notable implications for home builders and HVAC contractors active throughout 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 a leading factor in home air leakage across Pennsylvania, New Jersey, and Delaware? Leaked air can increase monthly energy costs, stress your HVAC system, and scatter dust and insulation across your living areas. This makes duct leakage test beneficial for all homes, new or old. Keep reading to find out why duct leakage test is essential and how it can improve your home.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To start a duct leakage test in Geigertown, PA, the technician will close and seal every supply and return register except the main return or air handler. A duct blaster — a specially calibrated fan — is then connected to the opening. It depressurizes the duct system to expose areas where air is leaking.

The duct blaster joins forces with a precision pressure sensor to monitor airflow and pinpoint leak points in the ducts without disturbing your home. A duct leakage test — often described as a duct blaster test — identifies leaking areas in your ducts so you can determine the most efficient sealing fix.

duct leakage test is rapid, clean, and performed without inconvenience to residents. Most tests in Geigertown, PA are done within 30 to 60 minutes, with improvements that strengthen comfort and efficiency for years to come.

How to Measure Duct Leakage

Duct leakage is measured in cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a nanometer to measure tiny pressure differences, making it possible to determine how much air the ducts are losing. 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 observe rising utility costs, temperature swings in different rooms, or regular HVAC breakdowns, duct leakage may be involved. According to ENERGY STAR, typical duct systems lose 20% to 30% of conditioned air through leaks. When outside hot or cold air seeps into your system, your HVAC must compensate, leading to higher energy costs and diminished comfort.

Overworked equipment also triggers more mechanical failures and costly service calls. Proper duct sealing helps promote the long-term integrity of your HVAC system, extending its lifespan and limiting continued maintenance needs.

Duct leaks can also allow dust, mold spores, moisture buildup, and multiple contaminants to enter 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 outlines that new homes must be built with fully sealed duct systems, utilizing materials like mastic, foil tape, and insulation to enhance energy efficiency. But what about leaks that lie far within enclosed wall or ceiling spaces?

Aerosol sealing technology (AeroSeal) gives technicians a way to reach concealed duct leaks without opening walls or ceilings. To set up this method, all vents are sealed off except for a single access point. The HVAC system is isolated, and a machine is fitted 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 leakage testing prior to and after aerosol sealing to observe the reduction and ensure treatment success.

Common Areas of Duct Leakage

The most typical place where ducts leak air is at their joints. Ductwork is built from multiple metal sections pressed tightly with fittings and metal bands, yet these joints are rarely airtight.

As your HVAC system cycles through heating and cooling each year, the ducts naturally 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 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 must remain below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet if the air handler is missing. For new construction, passing a duct leakage test is required before a home can receive an occupancy certificate.

If your home in Geigertown, 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 fundamental not only for code adherence but for boosting your home’s long-term efficiency and comfort.

Your technician will also share expert recommendations for fixing leakage problems, helping you achieve 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 position the duct tester on the HVAC unit or on a 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.
