For a Morrow home with mold in the AC or ducts, the work involves correcting the moisture, cleaning the coil, pan and metal ducts, and replacing fiberglass duct materials that cannot be cleaned. Running the system in the meantime can spread mold, EPA warns. Call the number on this page to be connected with a local mold remediation company in Morrow.

Morrow is an inland Clayton County suburb along I-75, about 12 miles from Atlanta and home to Clayton State University, Southlake Mall and the Georgia Archives. Houses, townhomes and apartments here share a common weak point: an air handler in a closet, attic or crawl space that runs for months and quietly collects water.
First steps
- Turn off the system if the heat is bearable. EPA says not to run HVAC equipment you know or suspect is contaminated.
- Find the indoor unit and check the drip pan and the drain line exit outdoors; a line that is not dripping on a hot afternoon may be clogged.
- Note which rooms smell worst, which often points to the duct branch with the problem.
- Avoid running ozone machines or foggers through the ducts; they do not remove the moisture that feeds growth.
- Keep a log of dates, photos and anything you have already tried.
- Renters should report the problem to the landlord in writing.

Common signs and causes
| What you see | Likely cause |
|---|---|
| One bedroom smells musty, others do not | Growth in that room's branch duct or boot |
| Water dripping from a ceiling vent | Sweating duct in the attic or a disconnected boot |
| Rust and slime in the pan | Pan that does not drain fully |
| House feels humid with the AC running | Oversized unit, airflow problem or duct leaks |
Clayton County was under a state of emergency during the September 2009 floods. In Morrow, building questions go to the City of Morrow Planning and Economic Development office at the Morrow Municipal Complex on Morrow Road (770-961-4002); ask whether replacing ducts or an air handler needs a permit before work starts. Georgia has no state mold license, so for any rebuilding ask whether the company holds a Georgia residential or general contractor license and check it on GOALS Verify Now.
What drives the cost
- The amount of ductwork involved and its material
- Whether duct board or lined duct must be torn out
- Repairs to the coil, blower or condensate drain
- Working room around the unit
For reference, Angi's Atlanta cost guide lists HVAC system mold remediation at $3,522 to $11,740.
