Air conditioning just in the nick of time.....Mitsubishi Mini Split

Since this will be our main building, our central location, we decided to install Air Conditioning. We were going to put in a window unit, but our windows would not accommodate a large enough unit and we did not wire a plug for one.
So after doing my research I found that the mini-split unit is by far the best for our situation. It is extremely energy efficient, quiet and maintenance free, that is if you get the Mitsubishi system ( /http://www.mitsubishicomfort.com/). This brand is the stand out in its feild.
We got one estimate from a guy that said it was the same unit as this because it had one component that was Mitsubishi. The inferior brands do cost less, but they are problematic. This guy was going to charge us almost the  same to install this other brand and of course was going to repair it when it went bad. What a great deal for him!
 Luckily we found Stanley AC in our neck of the woods. He was honest, reasonable and fast. We went with the 18 BTU wall mount, our room is 22 ' by 40' with 11' to 14 ' ceilings. It cost us $3,200.00 ( $500 of that was the installation cost) for everything,
