In Oldsmar, mold in the AC often starts in the garage or closet where the air handler sits, either from a drain line that keeps backing up or from surge water like Helene brought to streets near Shore Drive. Wet duct insulation and cabinet liner need replacing, and the source of the water has to be fixed. Call the number on this page to be connected with a local mold remediation company in Oldsmar.

What happens when you call
You'll be put in touch with an independent local company that works on AC and duct mold. The first questions are practical: where the air handler is, how old the system is, whether water came into the garage or house during a storm, and what you're seeing or smelling. On site, expect the company to open the cabinet, check the pan and drain, look at the coil area and the first sections of duct, and tell you which pieces it plans to clean and which to replace. Coil, blower and line work may go to an HVAC contractor working alongside it. Florida's mold statute keeps the assessor and the remediator separate on a structure for 12 months, so testing after the job is done by a different company.
What drives the cost
- Spread: growth confined to the cabinet versus growth throughout the supply ducts
- Replacement: feet of flex duct or duct board, cabinet liner, drain pan
- Location: a garage platform is easier than a cramped attic
- Containment: sealing the return and supply openings so spores stay put
- Related repairs: drywall in the air handler closet, or a new condensate line
Angi lists a typical Tampa-area range of $3,225 to $10,750 for mold remediation in HVAC systems.

Local conditions in Oldsmar
Oldsmar sits at the top of Old Tampa Bay, a planned city laid out in 1916 by Ransom E. Olds. Its homes are newer than much of Pinellas County, with a median build year of 1988 and only about 23 percent built before 1980. Newer doesn't mean immune. During Helene in 2024, surge reached several feet in a neighborhood a few blocks off Tampa Road; on Shore Drive, some homes were described as essentially totaled and one garage took about 4 feet of water. Streets along Tampa Road looked untouched, which caught many residents off guard. Any air handler that sat in a flooded garage should be assumed wet inside. Oldsmar contracts its building work to Pinellas County, so permits for replacement equipment go through Pinellas County Building Services.
Checklist before the company arrives
- System off at the thermostat
- Garage cleared around the air handler platform
- Photos of the pan, registers and any water line on garage walls
- Filter left in place so it can be inspected
- Notes on when the smell began
