I NEED TO GET NEW AIRCOND FER TWO ROOMS.
1 Room is 15ft by 20 ft.
Another room is 30 by 30 ft.
THE AIRCONS I LIKE SHUD HAVE STRONGEST FAN BLOWS!    TOO SICK OF AIRCON FAN WHICH HAVE SLOW PROBLEMS. 
THE AIRCON I WANT SHUD BE EFFECTIVELY COLD.    NOT INTERESTED IN OTHER FANCY FEATURES WITHOUT GETTING THE COLDNESS RIGHT IN THE FIRST PLACE.
WHICH ONE TO RECOMMEND?
