The Mr Slim air conditioner is great. It is a wall mounted unit without ducts in your walls or floors. There is a small opening in your wall for the connection to the outside unit. It comes in a neutural color that matches almost everthing.Depending on the size, it can be as small as a bread box. If you need to cool many rooms the unit can be larger(but not much). This one cools a five room house. We have it located in our living room and on the wall facing the hall way. Cooling is good at that angle. It has a remote to adjust the modes of temperature, direction flow of air, and other numerous functions.
We purchased this because we had conditioners in every window, and i couldn't stand having those windows blocked.. I think the cost of this runs a little less than traditional air conditioners. How i enjoy the comfort and the ability to see out my windows.. This is an AAA++
Update On Apr 05, 2010: With the temperatures above normal here this pass week-end, we sure thought of turning the air conditioning on. High 70's for Vermont in April, which made for a nice Easter.
