Why is my air conditioner leaking water?

An air conditioner leaking inside the house is a common problem. It could indicate that the air filter is dirty. Or, one of the following may be the culprit:

  • Clogged condensate drain line
  • Leaky, damaged, cracked or rusted drain pan
  • Dirty or broken coils
  • Frozen evaporator coils
  • Broken condensate pump
  • Not enough refrigerant
  • Disconnected drain line

If your AC is leaking, contact a repair service to find out what the problem is — and how much it will cost to fix it.
