Record what you can see
From a safe position, photograph where the water first appears: the air outlet, a cabinet edge, the wall behind the head, or a nearby pipe cover. Note the operating mode, how long it ran before leaking, whether you saw ice, and whether this is the first event. A photo taken before cleanup can help the technician, but do not restart the unit just to make a video.
Move dry belongings away if it is safe. Keep children and pets out of the affected space. If water has entered the wall or ceiling, tell the technician and contact an appropriate water-damage provider. A repair to the mini split and assessment of wet building materials are separate jobs, so ask who owns each.
What the visit should settle
We would want the technician to identify the source of the water, check the entire drain route and any pump, assess the pan and connections, and investigate ice or other operating evidence if present. Ask which finding supports the proposed repair and how the completed system will be tested for drainage and normal operation.
A blocked drain may be one possibility. It is not established by the fact that water landed on the floor. Our recommendation changes only when the source is identified and a repair is shown to hold under the relevant operating conditions.
If this is a recent installation, report it promptly to the installer and ask whether the written installation coverage applies. Keep the photos, service findings, and repair record together.
Your next step: Leave the leaking head off, send the safe observations and model information to a qualified ductless technician, and arrange separate electrical or damage assessment where needed.
