I'm having a ductless Mini-Split installed this week in a 300 square foot room and chose a 12,000 BTU AC/Heat Pump. The heating most likely won't be necessary (as the reason for the unit is to cool the room, regardless of the exterior climate) but a 9,000 BTU unit would have needed to work harder than the 12,000.

Also, this particular unit is 12,000 BTU cooling but 15,000 BTU heating. It's an LG and has a SEER rating of 20, so it should be very efficient, energy-wise.

Good. I was worried you'd freeze your ass off out there in socal
