# Why is my AC leaking water?

*Updated 2026-07-17*

**Short answer:** Almost always a clogged condensate drain: the system pulls gallons of water out of Bakersfield air daily, and when the drain line clogs with algae, the water finds your ceiling or floor instead. Sometimes a safety switch shuts the system off first, which looks like a dead AC but is actually a full drain pan.

An air conditioner is also a dehumidifier, and on a humid valley day it can pull gallons of water out of your air. All of it is supposed to leave through a small drain line, and that line is a warm, wet, dark tube, which is to say a perfect algae farm. When it clogs, the water backs up, and the story branches.

**If your system is in the attic**, the backup fills a secondary pan, and in better installs a float switch kills the system before the pan overflows. That failure looks like a mystery: AC dead on a hot day, no obvious cause. If your "broken" AC coincides with any water stain on a ceiling, suspect the drain before the equipment.

**If it's in a closet or garage**, you usually get the puddle first. Turn the system off before the water finds drywall or flooring; running it just makes more water.

**The homeowner fix that often works:** find the condensate line's exterior stub (a small PVC pipe dripping near the outdoor unit or exterior wall) and pull the clog through it with a wet/dry shop vacuum sealed to the pipe for a minute or two. A cup of white vinegar down the line's access tee every couple of months keeps the algae discouraged. That's the whole trick, and it's free.

**When it's our job:** no access tee to treat, a clog that won't pull, a rusted or cracked primary pan, or a float switch that needs installing because your attic install never got one, which we consider cheap insurance against a five-figure ceiling. These land in normal flat-rate territory, and the [$89 diagnostic](/services/ac-repair/) applies as always, waived with the repair.
