What Duct Sealing Includes

Duct sealing closes the leaks in an existing duct system so the air the air conditioner cools actually reaches the rooms. Nolan Air seals joints, collars, boots, plenum seams, and the connection at the air handler with mastic and mesh — not tape, which fails in attic heat within a few years. We also seal the return side, where leaks pull hot, dusty attic air into the system, and the air handler cabinet itself. Where the ductwork is otherwise sound, sealing is combined with reconnecting any separated runs, adding support straps, and insulating exposed metal that sweats. A duct leakage test before and after shows the improvement.

Why Duct Sealing Matters in Florida

Leaky ducts are the most common reason a correctly sized AC in Hillsborough County cannot keep the house cool. Supply leaks send conditioned air into a 130°F attic; return leaks pull that attic air — plus insulation fibers and humidity — into the air handler and the house. The results are a system that runs constantly, rooms that never cool, high indoor humidity, dust that reappears days after cleaning, and an air handler or ductwork that sweats and grows mold. Florida energy studies routinely find 20–30% duct leakage in existing homes. Sealing is one of the highest-return improvements available, and it is required to get rated performance from any new system.

How Nolan Air Handles Duct Sealing

We inspect first: airflow at every register, static pressure at the air handler, and a visual check of every accessible run. If the ductwork is beyond sealing — crushed, moldy, deteriorated — we say so and quote replacement instead. When sealing is the right fix, it is quoted in writing and usually completed in a day. Duct sealing in Cheval is often the first step before adding attic insulation, since sealing ducts under new insulation later is difficult.

Duct Sealing FAQs — Cheval

How do I know if my ducts in Cheval are leaking?

High bills with a newer AC, rooms that never cool, dusty air, high indoor humidity, or a sweating air handler. A duct leakage test measures it directly.

What does duct sealing cost?

It depends on the size of the system and how much is accessible. We quote after an inspection.

Is Aeroseal available?

Nolan Air seals ducts manually with mastic, which addresses the large leaks at joints and boots that cause most loss. We can discuss aerosol sealing for specific situations.

Will duct sealing lower my electric bill in Hillsborough County?

In most homes, yes — the amount depends on how much air was being lost. It also improves comfort and humidity control immediately.
