How to Fix an Air Conditioner Leaking Water Inside [Your House]

One common reason why an air conditioner is leaking water is due to a clogged condensate drain line. The drain line connects the evaporator coil to the outside world and can become blocked by debris, insects, or water droplets.

If the drain line is disconnected, then the condensed water will accumulate and cause flooding. A rusty or clogged drain pan can also cause the same issue. If the condensate pump malfunctions, then water will be unable to reach the condensate line and will leak instead.

Sometimes, the evaporator coils may be frozen due to a clogged filter or refrigerant leak. Finally, dirty or damaged coils can also lead to leakage.

While these are all simple problems that can be fixed with a bit of effort on your part, they can become costly if not corrected quickly.

Make sure to check your air conditioning unit regularly for signs of trouble and address any issues as soon as possible.
