Mini-split problems divide into two kinds. Some belong to the indoor unit — filters, the condensate drain, the fan, the controller — and are straightforward once reached. Others involve the outdoor unit and the refrigerant circuit between them, and those are sealed-system work that only a certified technician should open.
Heat pumps add a season to watch. In winter an outdoor unit is designed to defrost itself from time to time, which can look like a problem if you have not seen it before; a unit that stays iced up, or never runs its defrost at all, is the one worth a visit.
