Air conditioners pull a lot of moisture out of Florida air, and it drains through a condensate line. When that line clogs with algae or debris, water backs up into the pan and can overflow into a closet, ceiling or attic.
1. Stop the overflow
- Turn the system off at the thermostat. If water is near the unit's electrical parts, switch it off at its breaker or service disconnect.
- Empty the drain pan with a wet vac or towels.
2. Clear the line (if you are comfortable)
Many lines have an access port or cleanout near the air handler and an outlet outside the house. A wet vac on the outdoor end often pulls the clog out. Follow the manufacturer's guidance and avoid harsh chemicals unless the manual allows them.
3. Check for hidden damage
- Look at the ceiling under an attic unit and the walls and baseboards around a closet unit.
- Check that the float or safety switch in the pan works; it should shut the system off before an overflow.
4. Dry and watch for mold
Closets and attics stay humid, so wet drywall, insulation and the platform under the unit can grow mold fast. Dry them thoroughly or remove soaked materials.
When to call for help
Call if water came through a ceiling, soaked drywall or flooring, or you see mold near the unit. If you want a professional to take over, call (813) 574-3203 to be connected with a local water damage restoration company. The call is free; any work is agreed directly with the company.

Frequently asked questions
How often should the AC drain line be cleaned?
Many HVAC technicians suggest checking and flushing it during routine maintenance, and more often in humid months. Check your system's manual or ask your HVAC company.
Does insurance cover AC leak damage?
Sudden water damage from an AC overflow is often covered, but damage from a long-term, repeated leak or lack of maintenance may be excluded. Check your policy and report promptly.
