Hey scarab.

Joe has written a great article titled What BTU size is needed to cool and heat my room. The BTU's are going to be about the same, whether you are using a window unit A/C or a Mini Split system. If your building is not insulated well, then you would need to factor in possibly a larger unit. Click on the link above to see the chart for what size unit you will need.
