In Tarpon Springs, AC mold can come from Helene's surge reaching air handlers and ducts in homes near the Gulf and bayous, or from ordinary condensate problems in older systems. Shut the AC off, find the water source and replace any duct insulation that got wet. Call the number on this page to be connected with a local mold remediation company in Tarpon Springs.

Tarpon Springs and AC moisture
Tarpon Springs had long been mostly spared by hurricanes, which made Helene in 2024 a shock. On Seabreeze Drive, just north of Fred Howard Park, surge rose about 2.5 feet in 30 to 45 minutes; a family there for 47 years had water in their home for the first time, and a neighbor had to swim up Riverside Drive. The city's housing ranges widely, from about 537 units built in 1939 or earlier in and around the historic districts to a median build year of 1984. Older homes often have AC systems fitted in later, with ducts squeezed into attics and soffits where condensation is hard to spot.
What to do now
- Turn the AC off. EPA says running a system you suspect is contaminated can spread mold.
- Check the air handler for water in the pan, rust or a water line on the cabinet.
- If storm water came inside, note its height against floor registers and the air handler.
- Look at any attic ducts you can see safely for wet or collapsed insulation.
- Don't seal or paint over growth. EPA says sealants should never go over wet lining or active mold.
- Keep the filter in place so it can be checked.

Signs and likely causes
| What you see | Likely cause |
|---|---|
| Smell started right after Helene | Surge water reached the cabinet or low ducts |
| Growth around ceiling vents in an older home | Under-insulated duct boots sweating into the ceiling |
| Water stains on the hallway ceiling | Attic air handler pan overflowing |
| Dark slime in the pan | Slow or blocked condensate line |
| Musty smell in one room only | A single duct run with wet or damaged insulation |
Cost factors
Angi reports that mold remediation in HVAC systems typically costs $3,225 to $10,750 in the Tampa area. Older homes with tight attics, long duct runs or systems that were wet from surge sit toward the upper end. Tarpon Springs runs its own building department, which handles permits and inspections plus the FEMA 50 percent substantial damage rule for flood-zone repairs, so check with the Building Development Department before replacing equipment after a flood. Renters can contact the City of Tarpon Springs Code Enforcement Division about unrepaired leaks.
