Ductless mini splits fail differently from central systems. A head that runs but will not cool usually means low refrigerant charge from a flare-joint leak, a blocked outdoor coil, or a failed outdoor fan or compressor capacitor. Water dripping from the indoor head is almost always the condensate drain, since mini splits rely on a gravity fall or a small lift pump that clogs with biofilm. A blinking timer or operation light is a stored fault code, and the code tells the professional which sensor or board is reporting.
In Upper Arlington, OH homes these units often serve additions, converted attics, garages and finished basements where no ductwork exists, which means a failure takes out the only heating or cooling in that room. Multi-zone systems add another failure point, since one head behaving oddly can be a branch box or a shared line-set issue rather than the head itself.
