In a small rural town like Cedar Hill, duct and HVAC mold usually comes from the same places as anywhere in Middle Tennessee: a wet coil or drain pan, ducts sweating in a crawl space, or a leak nobody saw. Turn the system off and have the whole air path checked. Call the number on this page to be connected with a local mold remediation company in Cedar Hill.

Cedar Hill is a town of about 300 people on U.S. 41 in northwestern Robertson County, roughly 30 miles from Nashville. Its economy grew up serving surrounding farms, with tobacco the main crop, and the Cedar Hill Swamp Wildlife Management Area lies just across the railroad tracks. Low, wet ground nearby and Tennessee's humid summers both add moisture that a heating and cooling system has to handle.
Steps to take now
- Turn the system off. EPA advises against running HVAC equipment you suspect is contaminated.
- Check the condensate drain. A line that stays dry while the AC runs in July is probably blocked.
- Open the filter slot and look at the filter and frame without disturbing any growth.
- If the ducts run under the house, look at the wrap with a flashlight for sagging, tears or dark spots.
- Keep a fan or window unit going and run a dehumidifier in the main rooms.
- Arrange an inspection of the equipment and every duct run, not just the registers.

Clues and what's usually behind them
| Clue | Usually behind it |
|---|---|
| Stale smell when the heat first comes on in fall | Growth that started in the system during summer |
| Wet floor around the air handler | A cracked pan or clogged drain line |
| Damp, dark duct insulation | Humid air condensing on cold supply ducts |
| Growth on several supply grilles | Moist air in the ductwork, often from leaky joints |
Cost factors
Angi reports national ranges of about $600 to $2,000 for air duct mold cleaning and $3,000 to $10,000 for HVAC system mold work. Prices across Middle Tennessee vary, and a rural location can add travel. What moves the price most is whether insulated duct has to be replaced, which EPA says is generally the case when it's wet or moldy, along with crawl space access and moisture repairs. Robertson County is one of the counties where residential jobs of $3,000 or more need the state Home Improvement license, and projects of $25,000 or more need a Tennessee contractor's license. Ask the town or Robertson County which office handles permits for your address before ducts or framing are replaced. The Robertson County Health Department in Springfield can answer health questions, and the Tennessee Department of Health notes the state's humidity can lead to mold growth.
