Maintain top HVAC efficiency and stay aligned with local energy codes using trusted duct leakage test in Honey Brook, PA. Our certified technicians identify and quantify air leaks in duct systems so homeowners and builders can optimize comfort, reduce energy waste, and meet state-level requirements.

Why Duct Leakage Test is Important In Honey Brook, PA

States and municipalities commonly implement the 2015 IECC, International Energy Conservation Code for single-family dwellings and the 2018 International Energy Conservation Code for multi-family residences. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test together with a Blower Door Test must now be performed in all newly built or remodeled homes to comply with the 2015 regulations. Did you know that ducts are among the biggest contributors to air leakage in homes all across Pennsylvania, New Jersey, and Delaware? Leaked air can push your energy bills higher, pressure your HVAC system, and spread dust and insulation inside your house. 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 Honey Brook, PA, the technician seals all supply and return registers other than the main return or the air handler. A specially calibrated fan called a duct blaster is then connected to the opening. This fan depressurizes the duct system, making it easier to pinpoint exactly where air is leaking.

The duct blaster teams up with a precision pressure sensor to measure airflow accurately and locate duct leaks without affecting your home. A duct leakage test — sometimes referred to as a duct blaster test — uncovers air leaks in your ductwork so you can determine the ideal sealing approach.

duct leakage test is hassle-free, clean, and won’t interfere with residents’ daily routines. Most tests in Honey Brook, PA take around 30 to 60 minutes, but the efficiency and comfort improvements can last 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 helps you identify problem areas, evaluate potential improvements, and determine whether your home meets local energy code requirements in Honey Brook, PA.

Cost of Excessive Duct Leakage

If you’re struggling with expensive utility bills, inconsistent indoor temperatures, or continual HVAC problems, duct leakage might be the culprit. According to ENERGY STAR, leaking ducts cause the average home to lose 20%–30% of conditioned air. Hot or cold outside air creeping into your system forces the HVAC to work inefficiently, increasing energy spending and reducing comfort.

Overworked equipment also causes components to fail more often, leading to costly repairs. Proper duct sealing helps keep your HVAC system healthy over the long run, prolonging its lifespan and lowering continued maintenance needs.

Duct leaks can also allow dust, mold spores, excess moisture, and other contaminants into the duct system. This can worsen allergy reactions, negatively affect indoor air quality, and contribute to costly hidden structural damage over the years.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC states that new homes must have duct systems sealed completely with energy-efficient products such as mastic, foil tape, and insulation. But what should you do when leaks are located deep within your walls or ceilings?

Aerosol sealing technology (AeroSeal) helps target hard-to-reach openings deep within ducts. To begin this method, every vent is sealed except for one access opening. The HVAC unit is isolated, and a machine is installed onto 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 best for small to medium leaks. However, large openings usually require traditional manual sealing using mastic and tape. Technicians administer a duct leakage test prior to and following aerosol sealing to measure leakage changes and ensure the method was successful.

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 operates in varying temperatures across the year, the ducts undergo expansion and contraction. Over time, this movement weakens joint connections, producing gaps and leaks — making duct leakage test essential for both new and older homes in Honey Brook, PA.

Many energy auditors check for leaks by feeling along the ductwork and using a small tool to gauge the size of gaps between joints. If your duct system wasn’t properly sealed using mastic and approved tape, air leakage is very likely occurring.

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

To achieve a passing duct leakage result, your system should stay under 4 CFM per 100 square feet with the air handler attached, or 3 CFM per 100 square feet without it. For new construction, obtaining an occupancy certificate requires passing a duct leakage test first.

If your home in Honey Brook, PA cannot pass a duct leakage test, you are likely wasting money on heating and cooling — and causing long-term wear on your HVAC system. Meeting the 3–4 CFM requirement is necessary not only for meeting code standards but also for ensuring strong energy efficiency and indoor comfort.

Your technician will also give informed guidance on addressing leakage problems, enabling you to pass the test, reduce energy bills, and enhance your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins with all the ducts and registers sealed tightly using duct mask tape on both sides—supply and return.

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

The ducts are then placed under 25 Pascals of negative pressure. With the ducts depressurized, we obtain the leakage reading using the nanometer.
