Why Duct Leakage Test is Important In Elkins Park, PA

Various states and municipalities have adopted the 2015 IECC, International Energy Conservation Code for single-family houses, along with the 2018 International Energy Conservation Code for multi-family units. The change will result in several substantial implications for home builders and HVAC contractors engaged in work across 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 duct leakage is one of the most common issues affecting homes in Pennsylvania, New Jersey, and Delaware? Leaked air can lead to rising energy bills, added strain on your HVAC system, and unwanted insulation and dust spreading through your home. This makes duct leakage test vital for homes both old and newly built. Keep reading to find out why duct leakage test matters and what benefits it provides.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Elkins Park, PA, your technician seals all supply and return registers, leaving only the main return or air handler open. A duct blaster — a precision-calibrated fan — is then fitted to the duct opening. By depressurizing the system, it makes all air leaks much easier to detect.

The duct blaster, combined with a precision pressure sensor, measures airflow and detects leaks in the duct system without causing any disturbance in your home. A duct leakage test — also called a duct blaster test — locates the points where duct air escapes, helping you implement the right sealing solution.

duct leakage test is quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Elkins Park, PA take just 30 to 60 minutes, and the resulting improvements can enhance your home’s comfort and efficiency long-term.

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 register small pressure differences, which help calculate how much air is leaking from the ducts. Understanding this number helps you uncover weak points, analyze opportunities for upgrades, and check whether your home follows local energy code requirements in Elkins Park, 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, homes across the country lose 20% to 30% of their conditioned air through duct leakage. Outside air that’s too hot or too cold entering your system strains your HVAC, resulting in higher energy consumption and less comfort.

Overworked equipment also causes components to fail more often, leading to costly repairs. Proper duct sealing helps protect the long-term performance of your HVAC system, increasing its lifespan and lowering future maintenance requirements.

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 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) offers a method to access hidden leaks deep within ductwork. To perform the process, technicians seal all vents but leave one access point open. The HVAC system is isolated, and a machine is connected to the duct system. It pressurizes the ducts and distributes a fine aerosolized sealant that seals small openings traditional methods cannot reach.

This method is effective at treating small to medium leaks. However, big openings may still need to be addressed with manual mastic-and-tape sealing. Technicians complete a duct leakage test before and after aerosol sealing to track leakage reduction and confirm the treatment’s success.

Common Areas of Duct Leakage

The most usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system regulates temperatures through the seasons, the ducts expand when heated and contract when cooled. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Elkins Park, PA, new or older, benefit from duct leakage test.

Many energy auditors examine duct leakage by touching the ducts and using a small tool to measure the gap width between joints. If your duct system has not been properly sealed with mastic and approved tape, it’s very likely that leakage exists.

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, the home must pass a duct leakage test before qualifying for an occupancy certificate.

If your home in Elkins Park, PA fails its duct leakage test, you are likely facing inflated heating and cooling costs — along with increased strain on 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 advise you on the best ways to address leakage issues so you can pass the test, reduce utility bills, and enhance your home’s efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins by sealing all the ducts and registers with duct mask tape on both the supply and return side.

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