HVAC & Air Duct Mold Removal in Arrington, TN

From the first call to the written scope

The number on this page connects you with an independent local mold remediation company. The first conversation usually covers where the equipment is, how many systems the house has, when the smell started and whether any water got near the ductwork. Larger homes often have two or more systems, and only one may be affected. The site visit typically includes:

1. A look inside each air handler at the coil, pan, blower and filter rack.
2. A check of the plenums and accessible duct runs in the attic, crawl space or basement.
3. Moisture readings and photos of anything suspicious.
4. A written scope covering cleaning, replacement and the moisture fix, with each priced separately.

Price ranges and what moves them

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. Williamson County prices vary. Multiple systems, long attic runs, lined or flex duct that has to be replaced and tight access all raise the total. A job of $25,000 or more needs a contractor holding a Tennessee contractor's license, and mold remediation is the S-F classification.

Local conditions

Williamson County's emergency management office says the Harpeth River and its creeks are the main local flood sources, that flash floods can arrive with little warning, and that blocked culverts, ditches and drains can cause flooding too. It also notes that most streams and creeks are the property owner's responsibility and that a homeowner's policy doesn't cover flooding; coverage comes through the National Flood Insurance Program. The county points out that 20 inches or more of rain can fall within two days, as the May 2010 flood showed. Equipment in a crawl space near a creek or a clogged culvert is worth checking after any storm like that. Day to day, though, summer humidity on cold ducts and slow AC drains cause most of the trouble.

Arrington is unincorporated, so building permits for replacing ductwork or equipment go through the Williamson County Building Codes Division in Franklin, and electrical permits in the unincorporated county come from the State of Tennessee.

Get ready for the visit

• Turn off any system you suspect and leave the others running if they smell normal.
• Label which thermostat controls which system.
• Clear access to the attic hatch, crawl space door and air handler closets.
• Look up FEMA's Flood Map Service Center for your property if a creek is nearby.
