The answer to 'ductless system leaking water' is that a ductless mini-split system may leak water due to a clogged drain line, a refrigerant leak, or a problem with the indoor unit's condensate pump. Symptoms of a water leak include puddles around the indoor unit, water dripping from the unit, or high humidity levels in the room.
To fix a ductless system water leak, you may be able to try DIY solutions like clearing the drain line or cleaning the condensate pump filter. However, if the leak is caused by a refrigerant leak or a more complex issue, it's best to call a professional HVAC technician to diagnose and repair the problem. They can properly identify the source of the leak and make the necessary repairs to stop the water from dripping.
