HVAC & Air Duct Mold Removal in Mount Juliet, TN

Signs to take seriously

• A musty or mildew smell that tracks with the blower.
• Dark growth on the coil, the blower wheel or inside the return.
• Water collecting in or around the drip pan, or a drain line that has stopped flowing.
• Condensation dripping from ducts in the crawl space or attic.
• Ceiling stains around supply registers.

What puts water in Mount Juliet systems

Day to day, it's humidity. With two large lakes nearby and long Middle Tennessee summers, air conditioners here pull a lot of water out of indoor air, and ducts in crawl spaces and attics are exposed to muggy air all season. A drain line clogged with algae or a gap in the duct wrap is enough to start growth.

Flash flooding is the other risk. In August 2013, heavy rain closed many Mt. Juliet roads, including Old Lebanon Dirt Road, Curd Road and West Division Street, and two residents were rescued from a West Division Street home. In July 2026, overflowing streams and creeks flooded multiple parts of the city; about eight people were rescued, including a family taken by raft from a West Division Street home. Equipment and ducts in a crawl space that took on water in events like these need inspection before the system runs again. EPA says anything not dried within 24 to 48 hours should be assumed to have mold.

What decides the cost

Angi reports national ranges of about $600 to $2,000 for mold cleaning in air ducts and $3,000 to $10,000 for HVAC system mold work; local prices vary. The amount of insulated or flex duct to replace, coil and blower cleaning, flood damage to the air handler and access all play a part. Jobs of $25,000 or more need a contractor holding a Tennessee contractor's license, and mold remediation is the S-F classification. Check any company on TDCI's Verify a License search.

What happens when you call

You'll be connected with an independent local mold remediation company that will ask about the smell, the equipment location and any water. Expect a written scope with photos. The City of Mt. Juliet Building & Codes Department requires a permit to install or repair mechanical systems, so replacement ductwork or a new air handler will likely need one; ask who pulls it. Renters with an unfixed leak can report it to the city's Code Enforcement Department through SeeClickFix.
