Signs a ductless mini-split makes sense
Any of these usually mean a mini-split is worth a look.
A room or addition with no existing ductwork
Uneven temperatures between rooms, especially in additions or converted spaces

An older home where adding new ductwork isn't practical or affordable

Ductless mini-split installation: frequently asked questions
A ductless mini-split is a heating and cooling system made up of an outdoor compressor unit connected by refrigerant lines to one or more indoor units, each controlling its own zone. It heats and cools without any ductwork.
No, that's the point of a ductless system. Refrigerant lines run through a small opening in the wall instead of ducts, which makes mini-splits a common fit for additions, converted spaces, and older homes without existing ductwork.
