Buy a flow air conditioning unit!?

I bought one for just over $500. and it was worth it. I also bought an extra warrenty for I think, $35.00. The think sits on my floor and has an extension the sits across the window and is about six inches high. It is supposed to be for what little water is generated, but there is none! It cools very well up to 400 sg. ft. So my bedroom gets the pleasure of enjoying it; my computer sits at my desk in the bedroom! I also have a fan on medium that aims through the door and blows the cool air into the living room and dining and kitchen rooms. Another method I recently learned to keep the rooms cooler is to bend the brackets sitting on the wall around where the air comes from the air conditioning in the ceiling. Normally half of the wall unit bend away from where you want it to go. I bent them all towards where I want the air to flow towards. Now when I walk into my living room I can actually feel the air coming at my face and body. Awesome. My entire rooms are cooler now.
