Why Do Hanahan Homes Near the Water Feel Damp With the AC Running?
More Moisture to Remove
Hanahan homes near the Goose Creek Reservoir and the tidal creeks start with more moisture in the air, so the AC has to work as a dehumidifier too. When it can't keep up, the house feels cool but clammy.
| Sign | Likely Cause |
|---|---|
| Clammy air at 74 degrees | Oversized system short cycling |
| Musty smell from vents | Wet coil, pan or duct insulation |
| Sweating windows or vents | Indoor humidity above 60% |
| Mildew in closets | Poor airflow and trapped moisture |
What Indoor Humidity Should a Hanahan Home Have?
Aim for 40 to 55% indoors. Above 60%, mold and dust mites take off and the house feels warmer than the thermostat says.
- Run the fan on auto, not on.
- Keep filters clean so the coil can drain.
- Add a whole-home dehumidifier if numbers stay high.

Clogged AC Drain Lines Are Hanahan's Most Common Summer Call
Algae Grows Fast Here
Clogged AC drain lines are one of the most common summer calls we get in Hanahan, because warm, wet air feeds algae in the line. When it backs up, the float switch shuts the system off or water spills into a closet or ceiling.
| Step | What We Do |
|---|---|
| 1 | Clear the line with vacuum and flush |
| 2 | Check the pan and float switch |
| 3 | Treat the line to slow regrowth |
| 4 | Add a cleanout if there isn't one |
How Do I Stop My Hanahan Drain Line From Clogging Again?
Flush the line with a cup of white vinegar every month or two in summer, and get a tune-up each spring. Comfort Club visits include a drain flush every time.
