In Sarasota, AC mold often traces to storm water that reached air handlers and ducts on the keys and bayfront during Helene, or to a condensate drain that has been backing up in the city's humid air. Turn the system off, fix the water source and replace wet duct insulation. Call the number on this page to be connected with a local mold remediation company in Sarasota.
Sarasota in brief
The city sits on Sarasota Bay and takes in barrier keys facing the Gulf, including Lido Key, St. Armands Key, Bird Key and the northern part of Siesta Key. Water covers a large share of its total area. Although Helene passed more than 100 miles offshore in 2024, coastal parts of the city saw more than 4 feet of storm surge that damaged hundreds of homes and businesses, with St. Armands Circle and Lido Key flooding. Milton arrived while the city was still responding, and the city describes it as Sarasota's first-ever direct hit.
What to do now
- Turn off the AC. EPA says running a system you suspect is contaminated can spread mold.
- Check the pan and cabinet for water, rust or a flood line.
- If storm water got inside, measure how high it reached on walls and the air handler.
- Photograph growth on registers, the return and the closet.
- Avoid sprays and sealants in the ducts; EPA says sealants should never cover wet lining or active growth.
- Ask your contractor about the city's permit rules before replacing equipment.
What you see and the likely cause
| What you see | Likely cause |
|---|---|
| Musty air after surge on the keys | Floodwater soaked the air handler or low duct runs |
| Ceiling stains below an attic unit | Pan overflow from a clogged condensate line |
| Growth on the blower wheel | Persistent moisture in the cabinet |
| Damp, collapsed attic duct | Roof leak or torn duct jacket sweating |
| Smell only in one wing | One damaged duct run or a separate system zone |
Cost factors
Angi reports a typical Tampa-area range of $3,225 to $10,750 for mold remediation in HVAC systems; Sarasota pricing can vary. Cost rises with the amount of duct and liner to replace, coil or pan replacement, attic access and drywall repairs. The City of Sarasota's Hurricane Related Permit Guide requires permits for storm-related mechanical repairs through its online Hurricane/Storm Damage Application, and it allows removing storm-damaged drywall up to 4 feet above the floor; in special flood hazard areas those costs must be included at permit application. Renters can contact the City of Sarasota Code Compliance Division, which holds the property owner responsible for compliance, including at rentals.
