I currently have a Mr. Slim system in my converted garage. The room is 20x11 fully insulated and it has worked great for the past 3 years. I selected a system that could handle a much bigger room and it keeps the room ice cold if i need it to be.
I'm thinking of building a wall with an open doorway to split the room in half and make it 2 rooms of 10x11. The mini split is located in the back of the room and i'm wondering how well it would cool the front half of the room with a wall installed. If done, the back room where the mini split is would be a workout room and the front room would be a little media room. Just wanted to get some advice and see if I would be okay doing this. I just dont want that front room to be warm while the back freezes.
