All this trouble for this.
So, the board of my building is convinced there's a NYC law requiring brackets under all window air conditioner units. I found a PDF on the NYC Dept. of Buildings website saying people "may use" them. Doesn't sound like a law to me. Anyhue, the board threatened a $500 fine per A/C unit without a bracket. So, $90 worth of bracket hardware, a borrowed power drill, and 4 hours later, here we are. Isn't this silly?
At least it was kind of fun. I like working with my hands, and there aren't enough chances in life to use a power drill.
