Duct Sealing Services in New Port Richey, FL

Leaky ducts in your home mean your AC system works harder to maintain comfortable temperatures. You pay more in energy costs, and some rooms may still feel too warm or too humid. Our technicians use pressure testing and visual inspection to locate leaks at connections, joints, and seams throughout your duct system.

Once we identify the problem areas, we seal them using industry-approved mastic sealant or metal-backed tape rated for HVAC applications. Standard duct tape, despite its name, breaks down quickly in Florida's heat and humidity and isn't suitable for long-term duct sealing. We use materials that hold up for years, even in attics and crawl spaces where temperatures can exceed 140°F during summer.

Commercial buildings often have extensive duct networks running through ceiling plenums, mechanical rooms, and between floors. Air loss in these systems can significantly impact operating costs and occupant comfort. R.J. Kielty's commercial duct sealing services address the unique challenges of larger-scale systems.

We work with business owners, property managers, and facility directors to schedule service during off-hours when possible, minimizing disruption to your operations. Our team has experience with a wide variety of commercial duct configurations, from single-story retail spaces to multi-unit office buildings.

Aeroseal is a duct sealing method that works from the inside out. The process involves pressurizing your duct system and injecting a polymer-based aerosol sealant that finds and fills leaks automatically. It's especially effective for reaching leaks in ductwork that's hidden behind walls or buried in insulation where manual sealing isn't practical.

Aeroseal can reduce duct leakage by up to 90%, according to the technology's manufacturer. The sealant bonds to the edges of gaps and cracks, building up until each leak is closed. After the process is complete, we provide a printed report showing your system's leakage before and after treatment, so you can see the measurable improvement.

Before we seal anything, we need to know what we're dealing with. Our duct inspection process includes a visual assessment of accessible ductwork, pressure testing to measure total system leakage, and airflow measurements at each supply and return register.

These tests help us pinpoint where your system is losing air and how much. They also reveal other issues that could affect performance, such as collapsed flex duct, disconnected sections, or undersized runs. We share the results with you and explain what we find in plain terms before recommending any repairs.

Duct sealing and duct insulation go hand in hand. Sealed ducts that lack proper insulation still lose energy through heat transfer, especially in unconditioned spaces like attics. In Florida, uninsulated ducts in an attic can cause the cooled air inside to warm by several degrees before it reaches your living space.

R.J. Kielty installs and replaces duct insulation to the standards recommended by the Florida Building Code. We also repair damaged sections of ductwork, replace deteriorated flex duct, and re-secure connections that have come loose over time. Addressing these issues together gives you the best return on your investment.
