The answer to 'ductless system leaking water' is that a ductless HVAC system, also known as a mini-split, can leak water for a few common reasons. The most frequent causes are a clogged drain line, a problem with the condensate pump, or improper installation and insulation of the refrigerant lines. Symptoms of a water leak include standing water around the indoor unit, wet floors, or water dripping from the unit.
To fix a ductless system leak, you can try cleaning the drain line or checking the condensate pump first. However, if the issue is with the refrigerant lines or a more complex problem, it's best to call a professional HVAC technician to diagnose and repair the system properly. Attempting DIY repairs on a ductless system can be risky and may void the warranty, so it's generally recommended to have a qualified technician handle any major issues.
