According to the Florida historical marker in town, St. Cloud's Grand Army of the Republic post was once the largest in Florida and the second largest in the country, and the GAR hall was added to the National Register of Historic Places in 1997. The modern city has about 65,130 residents (ACS 2024 5-year), and its housing tells a newer story: the median home was built in 2003, and 72.5% of homes are owner-occupied.
For a newer house, a full duct cleaning is often not the first thing to price. EPA says it "does not recommend that air ducts be cleaned except on an as-needed basis," and lists three triggers: substantial visible mold in hard ducts, vermin, or ducts clogged with dust and debris. What newer Central Florida homes do commonly have is leaky ductwork.
Why duct sealing comes up in St. Cloud
Studies by the Florida Solar Energy Center at UCF found significant duct leaks in a majority of new central Florida homes tested, and estimated that leakage in an average 2,000 sq ft home can add 10–20% to annual heating and cooling cost. Ductwork often runs through hot attics, so a leaky return can pull in attic air.
St. Cloud has a local angle here. Its electric system is operated by OUC under an interlocal agreement, and St. Cloud customers are eligible for OUC conservation programs. OUC's Duct Repair / Replacement Rebate pays "100% of the cost, up to $100" as a bill credit when ducts are sealed with mastic (or mastic with embedded UL-approved tape) on all accessible boots, joints and seams. The rebate covers sealing and repair, not duct cleaning. Check OUC's current terms before you book. More on duct repair and sealing.

Independent companies follow up
Local air duct and HVAC companies contact you to quote. We don't do the work ourselves and aren't a contractor.
Check before you sign
Duct cleaning that removes grilles, AC coil work and duct repair are licensed air-conditioning contractor work in Florida. Ask for the CAC/CMC number and check it at MyFloridaLicense.com. A county business tax receipt is not a license. This is general information, not legal advice.
Storm history on the east side of the metro
Hurricane Ian dropped 13.13 inches at a station 8 miles east of St. Cloud in 2022, according to National Hurricane Center data. Milton in 2024 was much lighter here, with 3.65 inches recorded east of town. If floodwater ever reaches an air handler or duct, the Florida Department of Health says running the system without proper cleaning "will spread mold throughout your home."

St. Cloud FAQ
Does the OUC duct rebate apply in St. Cloud?
St. Cloud's electric system is operated by OUC, and St. Cloud customers are eligible for OUC conservation programs. OUC's duct repair rebate covers 100% of the cost up to $100 for qualifying mastic sealing of accessible boots, joints and seams. It does not mention duct cleaning, so don't expect cleaning to qualify. Confirm current terms with OUC.
My St. Cloud home was built in the 2000s. Do the ducts need cleaning?
Not necessarily. EPA recommends cleaning only as needed, for example when there is substantial visible mold in hard ducts, vermin, or heavy dust and debris coming from the registers. In newer homes, leaky duct joints are a more common concern, which is why many homeowners ask for a duct leakage check or sealing quote instead.
Who is allowed to seal or repair ducts in Florida?
Florida statute 489.105 puts installing, maintaining and repairing ductwork within the scope of a Class A or Class B air-conditioning contractor, and replacements may need a permit. Ask any company for its license number and look it up at MyFloridaLicense.com before work starts. This is general information, not legal advice.
