Duct Replacement in Tampa, FL

Most full duct replacements in Tampa run $2,500–$6,000, with larger homes, multi-zone systems, or rigid sheet metal trunk lines pushing $9,000+. The biggest cost drivers are home size, the number of supply runs, attic accessibility, and flex vs. rigid duct. We provide a detailed written quote after inspecting your existing system — no surprises on installation day.

Most Tampa homes (1,200–2,500 sq ft) are completed in 1–2 days. Day one is typically removal of the old duct system and installation of new trunk lines; day two is branch runs, sealing, and airflow testing. Larger homes or tight attic layouts may take a third day, and your AC is usually only offline for part of each day.

Sealing makes sense when the ducts themselves are structurally sound and the problem is leaky joints — it recovers 20–30% of lost air at a fraction of the cost. Replacement is the right call when flex duct is 15+ years old and brittle, sections have collapsed or torn, there's mold inside the ducts, or previous sealing attempts haven't fixed the performance. We'll inspect and tell you honestly which one your system needs.

Insulated flex duct is the standard for Tampa residential attics — it's cost-effective, and modern R-8 flex handles our 130–160°F attic heat well when installed with proper support and minimal bends. Rigid sheet metal performs better on long trunk runs and lasts longer, but costs more. Many of the best installs use a hybrid: rigid trunk lines with flex branch runs.

Yes — Hillsborough County (and Tampa, Pinellas, and Pasco) requires a mechanical permit for full duct replacement, and the work must be performed by a licensed contractor. Protek pulls the permit and schedules the inspection as part of every job under FL License #CAC18220411, so you don't have to deal with the county at all.
