The most common AC repair homeowners face is a clogged condensate drain line that trips a float switch and shuts the system off. Blockage forms from algae and debris in humid weather. This issue is widespread, usually quick to clear, and routine cleaning helps prevent repeats. A technician will vacuum the line, flush the trap, and inspect the pan and switch; if it returns, we look at line slope or a damaged pan. We handle this regularly across Northeast Florida.
Typical signs include:
- Water near the indoor unit or a full drain pan.
- AC off with no fault while the thermostat calls for cooling.
- Musty smell or gurgling at the drain line.
If you notice these, turn the system off and schedule service to prevent water damage.
