HVAC & Air Duct Mold Removal in Carrollton, GA

What causes mold inside a Carrollton AC system?

Carrollton is the Carroll County seat, about 41 miles west of Atlanta and home to the University of West Georgia and West Georgia Technical College. The Little Tallapoosa River runs through the northwestern part of the city, and Lake Carroll lies nearby. Around Adamson Square and out along US 27, homes range widely in age and style, but almost all run central air for much of the year. The AC coil condenses water out of humid air, and that water must drain. A clogged line, a rusted pan or ducts that sweat in a damp crawl space or hot attic leave moisture behind, and mold follows.

Which parts can be cleaned?

Sheet metal ducts with visible growth can often be cleaned; EPA's duct guidance says cleaning may be worth considering when mold is substantial and visible inside hard ducts. Fiberglass duct board and fiberglass-lined ducts are handled differently. EPA says when they are wet or moldy they cannot be effectively cleaned and should be replaced. The coil, pan and blower are cleaned and repaired, which may involve an HVAC technician. Ask that any coating or chemical in the bid be named and explained. A sound bid also lists the moisture cause and the fix for it, since cleaning a coil that will keep dripping into a clogged pan only buys a few months.

I rent in Carrollton. What should I do about a moldy AC?

Tell the landlord about the problem in writing and keep a copy. Georgia law (O.C.G.A. 44-7-13) requires landlords to keep rentals in repair, and Georgia Legal Aid notes that includes air conditioning supplied with the unit.
