Stonecrest HVAC mold usually starts where condensation is not draining, such as a clogged line or a full pan, or where ducts sweat in an attic or crawl space. Removal means fixing the moisture and cleaning or replacing the affected parts. Call the number on this page to be connected with a local mold remediation company in Stonecrest.
Stonecrest at a glance
Stonecrest, approved by voters in 2016, is the largest city entirely within DeKalb County, about 13 miles east of downtown Atlanta near the Mall at Stonecrest and Arabia Mountain. Much of its housing is suburban, with air handlers in attics, closets or crawl spaces depending on the home's design. Each location has its own moisture risks in a long, humid cooling season. Attic units depend on a drain line that can clog and a secondary pan that can overflow onto the ceiling below. Closet units can leak onto flooring and drywall. Ducts under the house sweat when crawl space air turns muggy, especially after heavy storms soak the red clay around the foundation.
What to do now
- Shut the system down if possible; EPA advises not running a system suspected of contamination.
- Look for water in the pan under the coil and on the floor or ceiling near the unit.
- Check the condensate line outside for a steady drip on hot days.
- Photograph any growth on grilles, the cabinet or ducts.
- Keep humidity under 60 percent with a dehumidifier while the system is off.
- Skip foggers and sprays until the source is known.

Cost factors
HomeGuide's 2026 national range for HVAC or duct mold remediation is $2,000 to $10,000, and metro Atlanta prices vary with each house. The duct type is a big factor, since EPA says moldy fiberglass duct board or lined duct should be replaced instead of cleaned. Duct length, access, containment and repairs to the equipment matter too. If drywall or ceilings are opened, the City of Stonecrest Building Department at 3120 Stonecrest Boulevard, Suite 190, issues interior finish, remodeling and trade permits; call (770) 224-0200. Stonecrest Code Enforcement's listed duties focus on exterior property maintenance, and its page links to the Georgia Landlord-Tenant Handbook for renters.
