A leaking air conditioner can be alarming, but in many cases, it’s a simple issue you can address yourself. Follow these steps to identify and fix the problem safely.

Common Reasons Your AC Leaks Water

Clogged Condensate Drain

Over time, dirt, dust, and algae can block the drain pipe.

Water backs up and leaks from the indoor unit.

Dirty Air Filter

A clogged filter reduces airflow, causing the evaporator coil to freeze.

When it melts, water can drip excessively.

Low Refrigerant Levels

Low refrigerant causes the coil to freeze and then leak water as it melts.

Improper Installation or Tilt

If the AC unit isn’t level, water may spill instead of flowing to the drain.
