Cost depends on how big your garage is, and if it's insulated. I have a 3 car, so a mini-split would have to be huge to start with, and it's not insulated, so it would have to be even bigger. I think you are looking at minimum $2k just for something adequate for 600sq-ft. $8k for 1200 sq-ft. Install is probably in the $1-2k range. I don't think it's cost effective for a 3 car garage. Better of insulating it and then getting the duct to the central AC work done, so long as your condenser can handle the extra square footage. If not, what I sometimes do is walk around and shut vents to unoccupied rooms.
