Conditions in Hiram
Hiram is a small Paulding County city about 23 miles west of Atlanta, centered on the US 278 and SR 92 retail corridor and crossed by the Silver Comet Trail. Much of its housing went up after 2000, and newer homes often put the air handler in the attic, where summer heat is intense and a clogged condensate line can overflow onto the ceiling below. Older homes are more likely to run ducts through a crawl space, where humid air makes cold ducts sweat.
Either way, the AC is pulling water out of the house for months each year. Mold grows wherever that water is allowed to linger: a pan that holds a puddle, insulation dampened by condensation, or a duct section that gets wet and stays wet. Builder-grade drain lines with no cleanout, and secondary pans that nobody checks, are common in homes put up quickly, so a first inspection often finds a problem that has been building for a few seasons. Filters that are left in too long also restrict airflow, which can make the coil run colder and drip more.
Handling it yourself vs bringing in a pro
| Situation | Homeowner can | Call a company when |
|---|---|---|
| Spots on a removable grille | Wash it and lower indoor humidity | It comes back quickly |
| Partly clogged drain line | Flush an accessible line per the maker's guidance | Water has soaked nearby materials |
| Growth inside ducts | Leave it alone | Always |
| Growth on coil or blower | Shut the system off | Always; involve an HVAC technician |

Signs
- A musty odor that follows the AC cycle
- Gray or black spotting around vents
- Ceiling stains under the attic unit
- Indoor humidity that stays high with the AC running
