I can't imagine my life before I had this fabulous air conditioner!!  My bedroom is quite large.   Large enough for 2 king size beds , 12 drawer dresser, a large 50" tv,2 night stands, a double door -5 drawer bureau, a desk and a recliner!!!  Every-night is heaven.  I live in South Texas where one day it's 90 and the next day its 70.  This air conditioner is the best cooling, the best in for sound and I have never seen this on any ac's that I have had in the passed, outside it has two braces that help position the unit in the window so if there should should be drainage it goes out (down) not back in the unit or back inside you home.   I'm thinking maybe I should get another  one just to have in maybe 15 - 20 years  when this one goes out!!  I love love this AC!!! BUY BUY IT!!!
