About Stuart
Duct Replacement in Stuart, FL.
Stuart wraps around the St. Lucie River and the Indian River Lagoon, and its homes span more than a century. In and around Downtown Stuart, houses built between the early 1900s and the 1960s got central air long after construction, so their ductwork was fitted wherever it could go: tight attics, soffits and closets, often with one return for the whole house. Rocky Point and the neighborhoods east of US-1 have mid-century homes close to the water, where salty, humid air reaches attics and corrodes metal fittings, hangers and register frames. Martin Downs, built mostly in the 1980s and 1990s, has duct systems that have been reconnected to new equipment more than once and are now tired, sagging and leaky. Newer homes near the Sailfish Splash area are younger but not immune to builder shortcuts. Stuart homeowners value personal service and straight answers, and that's how we approach duct replacement: show you what we found, then design a system that fits your home.
About this service
Duct Replacement in Stuart
Your air conditioner can only cool your home as well as your ductwork delivers the air. In South Florida, ducts live in some of the hottest attics in the country, and after years of summer heat, flex duct sags, inner liners tear, insulation flattens and connections pull loose. ENERGY STAR estimates that in a typical house, about 20 to 30 percent of the air moving through the duct system is lost to leaks, holes and poorly connected ducts. In a Florida attic, that cooled air is simply gone, and leaky return ducts pull hot, humid attic air back into your home.
Swift Air Conditioning specializes in whole-home duct replacement. We don't just swap old ducts for new ones in the same layout. Our team designs every system in-house, starting with a room-by-room Manual J load calculation to find out how much cooling each room actually needs, then a Manual D duct design that sizes every supply run, trunk line and return to deliver that airflow. Our goal on every job is every bedroom within 3°F of the thermostat, which matches the room-to-room comfort guideline in ACCA's Manual RS.
Installation is where good designs succeed or fail. Our crews seal every joint with mastic, insulate the new ducts for a Florida attic, support them so they can't sag, add return paths so closed bedrooms keep getting air and seal the connections at the air handler. We pull the permit, schedule the inspection and finish by measuring the airflow at every register and balancing the system.
Signs you may need new ductwork include rooms that never cool down, rising electric bills, dust that returns right after cleaning, a musty smell when the AC starts, sweating vents and ducts that are crushed, torn or disconnected in the attic. If your home still has its original ducts, or they've been patched through several AC replacements, a free in-home quote will show you what you have and what it would take to fix it. We serve homes from Vero Beach to Fort Lauderdale, and our team speaks Spanish. Call (561) 685-8408 to schedule your free quote.

Local details
Duct Replacement details for Stuart.
The free in-home quote for a Stuart home begins in the attic. We check access, clearance and the condition of the ducts, insulation and air handler connections, then measure each room for a Manual J load calculation that our team runs in-house. From those numbers we draw up the replacement layout with Manual D. In older downtown homes, that may mean creative routing through soffits and closets, plus return paths for bedrooms that have never had one. In Martin Downs, it usually means replacing tired flex with properly sized, well-supported runs. For river and lagoon homes, we use corrosion-resistant hardware where salt air reaches the ducts. Every joint gets mastic, every run is insulated, and old ductwork is hauled away. We file the permit with the local building department and set up the inspection. Then we measure airflow room by room and balance the system so every bedroom in your Stuart home is within 3°F of the thermostat.

Got questions?
Frequently asked questions
Yes. Many older Stuart homes received their ducts decades after they were built, so the original layout followed whatever path was available. We inspect the attic and the rest of the house during the free quote and design a layout that fits, giving every room a properly sized supply and a path back to the return so the bedrooms finally keep up.
They may be. Martin Downs homes in Stuart were mostly built in the 1980s and 1990s, so original or long-patched ducts are common. Torn liners, crushed insulation and leaky connections waste cooled air in the attic. The free in-home quote includes an inspection, so you can see the condition of your ducts before making any decision.
It can. Salt and humidity off the river and the lagoon reach attics through vents, corroding metal fittings, straps and register frames over time. For waterfront Stuart homes, we check for corrosion during the free quote, use corrosion-resistant hardware where it helps and seal the new system tightly so humid air stays out.
A room-by-room Manual J load calculation and a Manual D duct design done in-house, removal of the old ductwork, new ducts sealed with mastic, insulated and properly supported, return paths for bedrooms, sealed air handler connections, the permit and inspection, and a final airflow test and balance. The in-home quote is free.
ACCA's Manual RS comfort guidelines call for each room served by a thermostat to stay within 3°F of the thermostat setting while cooling. That's the target we design and balance to. After installation, we measure airflow and room temperatures to confirm the new duct system delivers it.
