You are right at the edge of what a 12k btu aircon can comfortably support.. you would be better off replacing it with a 18k btu unit..Around 25sqm...all open plan and a passage leading to the rest of the house. North facing home but normal sized windows with blinds and curtains that I keep closed during the day.
The outdoor unit sits on the south side of the house under the eaves so it doesn't get any sunlight.
