Signs Your AC Drain Line Is Clogged
Water, Smells, Shutdowns
Signs your AC drain line is clogged include water around the air handler, a ceiling stain under the attic unit, a musty smell, a full secondary pan and an AC that suddenly shuts off with the thermostat still on.
| Sign | What's Happening |
|---|---|
| Puddle by the air handler | Primary drain is backing up |
| Ceiling stain under the attic unit | Secondary pan is overflowing |
| AC shuts off, thermostat on | Float switch tripped by high water |
| Musty or moldy smell | Standing water in the pan or line |
| Water dripping from a soffit or window pipe | Secondary drain line is working, primary is clogged |
What Should I Do If My AC Is Leaking Water?
If your AC is leaking water, turn the system off at the thermostat, catch the water and call. Running it keeps making more water.
- Turn cooling OFF.
- Put towels or a pan under the leak.
- Check the outdoor end of the drain line for a visible clog.
- Don't pour bleach into a pan that's overflowing.
- Call 843-996-8904.

Why AC Drain Lines Clog So Often in the Lowcountry
Warm, Wet, Algae
AC drain lines clog so often in the Lowcountry because warm, wet drain lines are perfect for algae and sludge. A system here can pull 10 to 20 gallons of water out of the air on a humid day.
- Humidity: more water through the line means more growth.
- Warmth: attic drain lines stay warm all summer.
- Dust and pollen: feed the algae and sludge.
- Flat runs: lines without enough slope hold water.
- No traps or vents: lines without proper traps pull air and clog faster.

How Much Does AC Drain Line Repair Cost?
Clearing From $75-$250+

| Drain Repair | Typical Lowcountry Price Range |
|---|---|
| Clear and flush a clogged drain line | $75-$250+ |
| Add a float switch | $150-$300+ |
| Replace a rusted secondary drain pan | $250-$600+ |

Prices are typical Lowcountry ranges for planning. Your written estimate is the final word.
Does Drain Line Repair Fix Ceiling Damage?
AC drain line repair fixes the cause, not the drywall. Here's what usually happens next.
- We stop the leak and dry the pan.
- Small stains may dry out and can be painted with stain-blocking primer.
- Soaked drywall or insulation may need a contractor.
- Homeowners insurance sometimes covers sudden water damage, so take photos.

Float Switches, Drain Pans and Condensate Pumps
Your Backup Plan
Float switches, drain pans and condensate pumps are the backup plan that keeps a clogged drain from becoming a ceiling repair. Every attic air handler should have a secondary pan and a float switch.
| Part | What It Does |
|---|---|
| Primary drain line | Carries water from the coil outside |
| Secondary drain pan | Catches water if the primary backs up |
| Float switch | Shuts the AC off before water overflows |
| Condensate pump | Pumps water up and out when gravity can't |
| Drain trap and cleanout | Keeps air out and makes cleaning easy |

Frequently Asked Questions About AC Drain Line Repair
Quick Answers
Why Is My AC Leaking Water Inside?
A clogged condensate drain line is the most common cause. Water backs up into the pan and overflows.
Can I Unclog My AC Drain Line Myself?
You can pour vinegar in the cleanout and use a wet vacuum on the outside end. If water is already leaking, call a pro.
Why Did My AC Shut Off With Water in the Pan?
A float switch tripped to stop an overflow. That's it doing its job. The drain needs clearing.
How Often Should an AC Drain Line Be Cleaned?
At every tune-up, twice a year in the Lowcountry.
Is Bleach Safe for an AC Drain Line?
We recommend white vinegar. Bleach can damage some pans and fittings.
Do You Handle Leaks After Hours?
Yes. After-hours service covers active water leaks.
Do You Install Float Switches?
Yes, on any system that doesn't have one.
