Musty air from the vents in a Dover home usually means moisture is collecting somewhere in the AC system, most often at the coil, the drain pan or a condensate line that has stopped draining. EPA says not to run a system you think is contaminated, because it can carry mold through the house. Call the number on this page to be connected with a local mold remediation company in Dover.

Warning signs in the system
- A damp-cellar smell when the blower starts that fades after a few minutes
- Water pooling around the indoor unit or dripping from a ceiling vent
- Fuzzy or dark growth on the blower wheel, the coil housing or the back of a register
- Duct insulation that feels damp or sags in the attic
- An auxiliary pan under an attic unit holding standing water
Conditions in Dover
Dover is a small unincorporated community in eastern Hillsborough County, along U.S. 92 near Strawberry Crest High School, well inland from the bay. Surge is not the issue here. Humidity is. From late spring into fall the outdoor air is heavy with moisture, and an air conditioner that runs for months pulls that water out across its coil every day. When a condensate line gums up, the overflow lands in the pan, the closet or the attic insulation, and the cabinet stays wet long enough for growth to take hold. Summer thunderstorms and hurricane season can also drive rain through roofs and around attic units, wetting duct runs from above. EPA recommends holding indoor humidity under 60 percent and keeping drip pans clean and drain lines flowing, which prevents many of these problems before they start.

Cost of AC and duct mold work
For HVAC systems, Angi reports a typical Tampa-area remediation range of $3,225 to $10,750. A Dover job lands within that range based on how far growth has spread from the air handler, how many feet of insulated duct need replacing, attic heat and access, and whether the coil or pan needs an HVAC contractor's repair. Angi puts Tampa-area labor at about $75 to $120 an hour, which is why access and duct length matter so much.
After you call
You'll be connected with an independent local mold remediation company. Tell them where the unit is, when the smell started and whether there has been a leak. Ask what they'll do about the moisture source and what they plan to replace versus clean. Florida law (s. 468.8419) means the assessor and the remediator on one structure are normally different companies, so a clearance check should come from a separate assessor. For health questions, the Florida Department of Health in Hillsborough County is the local office.
