The answer to 'mini split leaking water' is that a leaking mini split air conditioner is a common problem that can be caused by several issues. The most common causes are a clogged drain line, a refrigerant leak, or a problem with the condensate pump.
If you notice water leaking from your mini split, first check the drain line to make sure it's not clogged with debris. You can try clearing the line yourself, but if that doesn't work, you may need to call in a professional HVAC technician to diagnose and repair the issue. A refrigerant leak or issues with the condensate pump often require more complex repairs that are best handled by a qualified technician.
