HVAC & Air Duct Mold Removal in Gallatin, TN

Gallatin's flood history and your ductwork

The city sits on Station Camp Creek, with Town Creek near downtown and Rankin Branch among the streams mapped in the Sumner County Flood Insurance Study. In May 2024, normally dry Town Creek overflowed near downtown after hours of rain. The Barton Drive neighborhood was hit hardest, with water under and into homes and crawl space HVAC units and ductwork ruined; one resident said the water ran higher than in the 2010 floods. In May 2017, Station Camp Creek spilled onto Lower Station Creek Road and homes on Cumming Lane flooded. Housing here is relatively new, with a median year built of 2002, but newer ductwork is just as vulnerable to standing water as old.

Clean it or replace it?

Signs to watch for

• A musty smell tied to the blower cycle.
• A water line or mud on the air handler or duct jackets in the crawl space.
• Growth on register covers, the return grille or the filter frame.
• Cooling that suddenly feels damp, or a unit that short-cycles after a flood.

Timing and seasons

After a flood, act fast: EPA says materials not dried within 24 to 48 hours should be treated as moldy, and a contaminated system should stay off. Without a flood, trouble tends to surface in early summer, when the AC starts running hard and humid air hits cold ducts. Spring is a good time to have the drain line flushed and the crawl space checked, and fall is the time to look at the furnace side before heating season, since a heat exchanger cabinet that sat in water needs evaluation too. If ducts or equipment are replaced inside city limits, ask about permits from City of Gallatin Building Codes. Renters whose landlord won't fix the moisture can contact Gallatin Code Enforcement, run through the police department, which takes tenant complaints about poor housing conditions.
