Whynter 12,000 BTU Dual Hose, Frost White (ARC-12SD)
The only problem of this air conditioner is just located at the short venting hoses. For people who have the high window, it makes them to mount the dual vents vertically and of course it will give a little difficulty. But for normal window position, it is perfect choice
If you are looking for a quiet, lightweight and small portable air conditioner, this air conditioner can be the good choice. But even it looks small; the power in cooling 400 square feet looks amazing enough. For the price maybe it looks expensive enough. But if you compare it with the features and the performance it has, this must be worth your money.
