Duct Leakage Test in Revere, PA

Ensure your HVAC system operates efficiently and meets local energy codes with professional duct leakage test in Revere, PA. Our certified technicians test and measure ductwork air leaks, helping homeowners and builders improve overall comfort, reduce wasted energy, and comply with state mandates.

Why Duct Leakage Test is Important In Revere, PA

Numerous states and municipalities rely on the 2015 IECC, International Energy Conservation Code for single-family properties and apply the 2018 International Energy Conservation Code to multi-family properties. The change will create considerable implications for home builders and HVAC contractors carrying out projects in 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 duct leakage is one of the most common issues affecting homes in Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. This makes duct leakage test essential for both new and older homes.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To begin performing a duct leakage test in Revere, PA, your technician closes off all supply and return registers except the main return or air handler system. A calibrated duct blaster is then secured to the opening. Its function is to depressurize the duct system, creating conditions that highlight any escaping air.

The duct blaster, working hand in hand with a precision pressure sensor, measures airflow and identifies leaks in the ductwork without impacting 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 hassle-free, clean, and won’t interfere with residents’ daily routines. Most tests in Revere, PA are performed within 30 to 60 minutes, and the positive impact on comfort and efficiency can remain for years.

How to Measure Duct Leakage

Duct leakage is measured using cubic feet per minute (CFM) per 100 square feet of conditioned floor area. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number lets you identify inefficiencies, weigh improvement options, and confirm your home’s compliance with local energy code requirements in Revere, PA.

Cost of Excessive Duct Leakage

If you’re experiencing spikes in utility bills, uncomfortable temperature variations, or ongoing HVAC repair needs, duct leakage may be to blame. According to ENERGY STAR, the majority of homes lose 20% to 30% of conditioned air through duct leaks. Hot or cold outdoor air infiltrating your system makes your HVAC system work overtime, which boosts energy costs and reduces comfort.

Overworked equipment also brings more system failures and higher repair expenses. 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 cause dust, mold spores, and excess moisture — along with other contaminants — to infiltrate the duct system. This can make allergies more severe, reduce the quality of indoor air, and produce costly structural harm behind walls or ceilings as time progresses.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC mandates fully sealed duct systems in new homes, made from energy-efficient materials like mastic, foil tape, and proper insulation. But what if the leaks you’re dealing with are deep inside the walls or ceilings?

Aerosol sealing technology (AeroSeal) can access interior duct leaks that are difficult to reach manually. To execute this method, all vents are sealed shut except a single access point. The HVAC system is isolated, and a machine is attached to the duct network. It pressurizes the ducts and emits a fine aerosol sealant that fills tiny gaps and holes that standard sealing methods can’t access.

This method excels at sealing small to medium leaks. However, bigger holes often must be sealed manually with mastic and tape. Technicians use before-and-after duct leakage tests to measure improvement and make sure the aerosol sealing process was successful.

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 cycles through heating and cooling each year, the ducts naturally expand and contract. 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 Revere, PA.

Many energy auditors assess duct leakage by touching the ductwork and using a small tool to check the width of gaps where joints connect. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

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

To achieve a passing duct leakage result, your system needs to measure under 4 CFM per 100 square feet when the air handler is included, or 3 CFM per 100 square feet when it is not. For new construction, the duct leakage test must be passed prior to the home being approved for an occupancy certificate.

If your home in Revere, PA doesn’t pass a duct leakage test, chances are you’re paying more for heating and cooling — and adding long-term stress to your HVAC equipment. Meeting the 3–4 CFM requirement is significant not only for meeting local code but also for maintaining optimal comfort and efficiency in your home.

Your technician will also provide expert insights into correcting leakage issues so you can meet passing standards, lower your utility expenses, and improve overall 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 mount the duct tester onto the unit or onto 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.
