HVAC & Air Duct Mold Removal in Thompson's Station, TN

What homes in Thompson's Station deal with

Thompson's Station grew from railroad-era roots, saw a Civil War battle in 1863 and incorporated as a town in 1990. Wherever the air handler sits in your house, attic, crawl space or closet, it faces the same climate. Summers here are long and humid, so the coil wrings water out of the air almost every day from May to September. That water has to drain. Ducts in unconditioned spaces also have to stay insulated and sealed, or they sweat. When the May 2010 flood dropped about 14.4 inches of rain on the town over two days, crawl spaces near creeks were the ones most exposed. Williamson County still warns that flash floods can come with little warning and that blocked culverts and ditches can flood property too, so check under the house after any heavy storm.

What you can do vs what needs a pro

EPA says a homeowner can usually handle a moldy area under about 10 square feet. Growth inside the equipment or ducts is a different matter, because the blower can spread it.

Signs to look for

• A musty smell that follows the blower.
• Water around the air handler or a stain on the ceiling below it.
• Growth on supply registers or the return grille.
• Damp duct wrap or condensation on metal duct.

Seasonal timing

Book drain and coil maintenance in spring, before the cooling load ramps up. Check the attic in July and August, when duct sweating is worst. Jobs of $25,000 or more need a Tennessee contractor's license, and mold remediation is the S-F classification. If ductwork or equipment is replaced, building permit applications go to the Town of Thompson's Station, where Planning and Codes review them together. The Williamson County Health Department in Franklin can help with health questions.
