Westmoreland is a small Sumner County town on the Kentucky line, about 40 miles from Nashville, and its homes share the region's humid summers and ductwork in crawl spaces and attics. Mold in an HVAC system usually grows on the coil, in a drain pan that holds water, or on ducts that sweat, and removal means cleaning or replacing those parts and drying out the cause. Call the number on this page to be connected with a local mold remediation company in Westmoreland.

How to tell the system may have mold
- The smell is strongest right after the furnace or AC cycles on.
- Black or green spotting appears on the louvers of supply registers.
- The filter comes out damp, or has growth on the frame.
- You hear gurgling at the unit or find water on the floor around it.
- Duct wrap in the crawl space is beaded with water on humid days.
Moisture sources in and around Westmoreland homes
Northern Sumner County gets the same hot, sticky summers and wet springs as the rest of Middle Tennessee, and a heating and cooling system here deals with both. In summer, the coil removes water from the air and depends on a clear drain to get rid of it. In a crawl space, humid outdoor air reaches cold supply ducts and condenses. In an attic, a duct joint or ceiling boot that leaks cold air can drip onto insulation and drywall. Westmoreland is also among the incorporated communities covered by the Sumner County Flood Insurance Study and FEMA flood maps, so check those maps if your equipment sits low and you live near a stream.
None of these causes is unusual, and most are fixable. The point of a remediation visit is to find which one applies to your house before anything gets cleaned.

What changes the cost
Angi reports national ranges of about $600 to $2,000 for duct mold cleaning and $3,000 to $10,000 for mold work on HVAC systems. Local prices vary, and a company may charge for travel to a smaller town. The rest depends on how much of the system is affected, whether lined or flex duct must be replaced, how easy the equipment is to reach and what the moisture repair involves. Jobs of $25,000 or more need a Tennessee contractor's license, and mold remediation is the S-F classification; check any company on TDCI's Verify a License search.
When you call the number on this page
You'll reach an independent local mold remediation company. Describe the smell, where the equipment is and anything you've seen. Ask for a written scope with photos. If ductwork or equipment gets replaced, check with the City of Westmoreland, where building permit applications are approved by the city's Building Inspector. For health questions, the Sumner County Health Department has clinics in Gallatin, Hendersonville and Portland.
