Thonotosassa homes, from lakeside houses to rural properties along U.S. 301, share the same AC mold risk: a system that pulls water out of humid air and grows mold when that water doesn't drain. EPA says to stop running a system you think is contaminated. Call the number on this page to be connected with a local mold remediation company in Thonotosassa.

What shapes AC mold in Thonotosassa
Thonotosassa sits in northeastern Hillsborough County between the Hillsborough River on the north, I-4 on the south and I-75 on the west, with Lake Thonotosassa near its center and Fort King Road and Morris Bridge Road running through. It is mostly suburban, though about 23 percent of the community was counted as rural in the 2020 Census. The main moisture driver is the climate: air conditioners here run most of the year, condensate lines clog, pans rust and attic ducts sweat. If your property is near the river or the lake, Hillsborough County notes that Special Flood Hazard Areas carry a 1 percent annual chance of flooding and that most homeowner policies don't cover flood damage.
Homeowner job or company job?
| What you're dealing with | Homeowner? | Notes |
|---|---|---|
| Dirty or damp filter | Yes | Replace it and find out why it got wet |
| Clogged condensate line | Sometimes | Follow the manufacturer's instructions or call an HVAC contractor |
| Small surface spots on a grille | Yes | EPA says areas under about 10 square feet are usually manageable for a homeowner |
| Growth on the coil or blower | No | A mold company, often working with an HVAC contractor |
| Moldy flex duct or duct board | No | EPA says it can't be cleaned effectively and should be replaced |
| Growth in several parts of the system | No | EPA warns partial cleaning can re-contaminate the whole system |

Signs
- A musty smell that starts with the blower
- Rust or standing water in the pan
- Sagging, damp duct insulation in the attic
- Spots that return to supply vents within days
Seasonal notes
Trouble tends to show up in mid to late summer, after systems have run for months, and after tropical storms that leave a house closed up and without power. If a storm floods a property on a private well, the Florida Department of Health in Hillsborough County advises disinfecting the well and boiling water if you're unsure it's safe; that's about drinking water rather than the AC, but it belongs on the same post-flood list. Spring is a good time to have the drain line and pan serviced before the heaviest cooling months.
