HVAC & Air Duct Mold Removal in Tyrone, GA

Why did mold show up in my Tyrone home's AC?

Tyrone sits about 22 miles from Atlanta, with Line Creek forming its western boundary with Coweta County and Georgia 74 running through. Homes here generally rely on central air, and the ducts typically run through an attic or crawl space. In summer, the coil pulls water out of the air constantly. If the pan holds water, the condensate line clogs, or a supply duct sweats in a muggy crawl space, that moisture never leaves, and mold grows on the coil, the pan or the duct insulation. Larger homes with two systems double the number of places to check. A second-floor unit in the attic and a first-floor unit in the crawl space each have their own pan, drain and duct runs, and one can be fine while the other is the source.

Will the company clean my ducts or replace them?

That depends on what they are made of and how far the growth goes. EPA's duct cleaning guidance says cleaning may be worth considering for substantial visible mold inside hard sheet metal ducts. For fiberglass duct board or ducts lined with fiberglass, EPA says wet or moldy material cannot be effectively cleaned and should be removed and replaced. Flex duct with soaked insulation is usually replaced as well. Whatever the plan, it should start with the moisture source; cleaning alone does not keep mold from returning.

Do I need a permit, and who do I call?

The Town of Tyrone Building Department, part of Community Development and operated with SAFEbuilt, issues residential and commercial building, HVAC, electrical and plumbing permits. Replacing an air handler or significant duct runs will likely need an HVAC permit, so ask the contractor to pull it. If you rent and a leak has not been fixed, Tyrone Code Enforcement takes reports through an online Report A Code Enforcement Violation form; give the landlord written notice first and keep a copy.
