A mini split leaking water inside usually means the condensate isn’t draining, most often from a clogged drain line or a dirty coil restricting airflow. The next most common causes are a stuck or failed condensate pump, a mis-leveled wall unit, or a frozen coil that melts and overflows. This is a common, fixable issue, but it can damage walls or electronics if ignored. Our technicians handle this routinely throughout the Holly area and can clear the drain, clean the coil, and confirm proper pitch and pump operation; repairs we perform carry a 3-year guarantee. A tech’s-eye hint: on ductless heads, slime in the tiny drain outlet after humid weeks is a frequent culprit.
If you want to limit damage before service:
- Turn the unit off and place a towel or pan under the head.
- Clean the return filter; a clogged filter can cause icing and overflow.
- Check the visible drain hose for kinks; do not open sealed panels.
- Call for service if you see ice on the coil, repeated leaks, or error codes.
Do not run the unit again until the cause is corrected to prevent water damage and mold growth.
