Why Duct Leakage Test is Important In Parsip Pany-Troy Hills, NJ

In many jurisdictions, the 2015 IECC, International Energy Conservation Code governs single-family buildings, while the 2018 IECC applies to multi-family buildings. The change will create several important implications for home builders and HVAC contractors operating within the state. A Duct Leakage Test and a mandatory Blower Door Test are now required for all new construction or remodeled homes under the 2015 regulatory standards. Did you know that ducts are frequently the biggest contributors to home air loss in Pennsylvania, New Jersey, and Delaware? Leaked air can escalate your energy costs, force your HVAC system to work harder, and move insulation and dust throughout your house. This makes duct leakage test important for all types of homes, whether new or old. Continue reading to learn why duct leakage test is essential and how you can benefit.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To perform a duct leakage test in Parsip Pany-Troy Hills, NJ, the technician begins by sealing every supply and return register except for the primary return or air handler unit. A duct blaster, which is a specially calibrated fan, is then installed at the opening. The fan depressurizes the ducts, helping identify all points where air may be escaping.

The duct blaster functions with a precision pressure sensor to analyze airflow and spot leaks in the duct system without affecting your home’s comfort. A duct leakage test — also known as a duct blaster test — pinpoints where air is escaping from your ducts, helping you choose the best sealing methods.

duct leakage test is quick, neat, and intentionally non-intrusive for anyone living in the home. Most tests in Parsip Pany-Troy Hills, NJ 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 specified in cubic feet per minute (CFM) for each 100 square feet of conditioned space. Your technician uses a nanometer to evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number helps you reveal problem areas, consider enhancement strategies, and validate that your home meets local energy code requirements in Parsip Pany-Troy Hills, NJ.

Cost of Excessive Duct Leakage

If you’re dealing with rising utility bills, inconsistent room temperatures, or repeated HVAC issues, duct leakage could be the reason. According to ENERGY STAR, the majority of homes lose 20% to 30% of conditioned air through duct leaks. 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 heightens the chance of system failures and expensive repairs. Proper duct sealing helps improve the long-term health of your HVAC system, boosting longevity and reducing ongoing maintenance requirements.

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 ensures that new homes are built with duct systems sealed entirely using 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) reaches interior duct leaks that traditional sealing methods can’t access. To apply this method, every vent is sealed aside from one access point. The HVAC system is isolated, and a machine is connected to the ducts. 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 is effective for addressing small to medium leaks. However, larger holes still need manual sealing with mastic and tape. Technicians run leakage tests both before and after aerosol sealing to gauge how much air loss decreased and confirm proper results.

Common Areas of Duct Leakage

The most frequent point of air leakage in ductwork is the joints. Multiple metal parts are pressed together using tight fittings and metal bands, although these junctions are seldom airtight.

As your HVAC system cycles through heating and cooling each year, the ducts naturally expand and contract. Over time, this movement allows the joints to loosen, producing gaps and leaks — which is why a duct leakage test is suggested for homes of all ages in Parsip Pany-Troy Hills, NJ.

Many energy auditors look for leaks by feeling the ducts and using a small tool to evaluate how wide the gaps at the joints are. If your duct system does not include sealing with mastic and approved tape, leakage is highly likely.

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, a passing duct leakage test is a required step before final occupancy certification can be awarded.

If your home in Parsip Pany-Troy Hills, NJ is unable to pass a duct leakage test, you are probably spending too much on heating and cooling — while your HVAC equipment endures long-term stress. Meeting the 3–4 CFM requirement is important not just for compliance, but for safeguarding your home’s comfort and long-term energy efficiency.

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 closing off every duct and register with duct mask tape across both the supply and return sides.

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

The ducts are then depressurized to 25 Pascals. At that point, the nanometer allows us to get an accurate duct leakage measurement.
