Keep your HVAC system running at peak efficiency and in full compliance with local codes through expert duct leakage test in Fairview Village, PA. Our certified technicians inspect and measure air leakage in ductwork, enabling homeowners and builders to boost comfort, prevent energy waste, and adhere to state guidelines.

Why Duct Leakage Test is Important In Fairview Village, PA

Many states and municipalities oversee single-family buildings under the 2015 IECC, International Energy Conservation Code and multi-family buildings under the 2018 International Energy Conservation Code. The change will introduce meaningful implications for home builders and HVAC contractors active in the state. A Duct Leakage Test as well as the required Blower Door Test must now be performed on new or remodeled homes following the 2015 regulations. Did you know that ducts are a significant source of air leakage in residential properties 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 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 initiate a duct leakage test in Fairview Village, PA, your technician seals all supply and return registers, leaving only the main return or air handler open. A specially calibrated duct blaster fan is then secured to the opening. Its job is to depressurize the duct system, allowing air leaks to reveal themselves clearly.

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 — often referred to as a duct blaster test — identifies air loss in your ducts, allowing you to find the most effective ways to seal them.

duct leakage test is efficient, clean, and performed without bothering residents. Most tests in Fairview Village, PA are completed within 30 to 60 minutes, and the improvements can benefit your home’s comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is assessed using cubic feet per minute (CFM) per 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 allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Fairview Village, PA.

Cost of Excessive Duct Leakage

If your energy bills are unusually high, your rooms feel unevenly heated or cooled, or your HVAC system needs frequent repairs, duct leakage could be the issue. According to ENERGY STAR, leaking ducts cause the average home to lose 20%–30% of conditioned air. Hot or cold outside air leaking in makes your HVAC system work more than it should, driving up energy costs and diminishing comfort.

Overworked equipment also triggers more mechanical failures and costly service calls. Proper duct sealing helps protect and extend the long-term lifespan of your HVAC system, minimizing the need for repeated maintenance.

Duct leaks can also permit dust, mold spores, extra moisture, and other airborne contaminants into the duct system. This can worsen allergy flare-ups, reduce indoor air quality, and cause long-term structural deterioration 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) is one way to reach hidden openings inside ductwork. 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 injects a fine aerosolized sealant that targets small holes and gaps unreachable by traditional sealing methods.

This method is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians do a duct leakage test before and after aerosol sealing to calculate how much leakage has been reduced and validate the results.

Common Areas of Duct Leakage

The most likely place for ducts to leak air is through their joints. Ductwork involves multiple metal pieces pressed together with secure fittings and metal bands, yet these connections are rarely perfectly airtight.

As your HVAC system runs through seasonal heating and cooling, the ducts experience ongoing expansion and contraction. Over time, this movement weakens the joints, creating gaps and leaks — a key reason duct leakage test is recommended for new and older homes in Fairview Village, PA.

Many energy auditors look for duct leakage by running their hands along the ducts and using a small tool to measure the width of gaps at the joints. If your duct system wasn’t sealed using mastic and approved tape, there is a strong chance that air leaks are occurring.

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

To achieve a passing duct leakage result, your system must show under 4 CFM per 100 square feet if the air handler is installed, or 3 CFM per 100 square feet if it is not. For new construction, a duct leakage test must be successfully passed before the home can obtain an occupancy certificate.

If your home in Fairview Village, 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 essential not only for following building code, but for keeping your home comfortable and energy-efficient.

Your technician will also provide expert strategies to address leakage concerns, helping you achieve a passing score, bring down utility bills, and boost home efficiency.

The Duct Leakage Test Steps Explained

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

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

The ducts are then brought to a depressurized pressure of 25 Pascals. Once depressurized, we use the nanometer for a leakage reading.
