Does this unit come with Support Brackets?
Considering the size and weight (over 100lbs?) does this AC have to be installed with support brackets? How did you install it on the window?
There are support brackets on the outside of the window. They only adjust the height of the AC unit so that it drains properly. They are not meant to hold weight. I have no problem with the unit in my window. It is very well balanced and the window is the only thing holding it there. No damage to my window at all. I was extremely surprised once it was installed. When I first saw the brackets I thought they were for support. Hope this helps.
