I am looking for a good ac in my bedroom. Right now I am having 1.5 ton window ac installed but it consumes around 10.5 amp, so now its time for me to decide between split ac or window ac? Which would be preferable... my bedroom is about 200 sq feet. So kindly let me know please..

Spot/window cooling is always cheaper to operate than split or central air.

You are cooling a smaller space rather than the entire house.

This is way to large for a 200 sq ft room.
