Guidance Appreciated for Window AC Unit Installation
I have purchased a new window AC unit to install in my daughter's Chicago 6th apartment. As you can guess, I want to make sure I install it properly. The unit to be installed is a 12,000 BTU Whirlpool W5WCE128YW. The standard installation in the manual assumes a nice flat sill to work with which we do not have. There is a 1-5/8" high channel which the metal window closes into which sits on the marble sill. I would like to know the best with to deal with this sill obstruction, the marble sill, the metal window frame, the potential necessity of additional AC support if needed, and the brick apartment building exterior wall. The only mounting hardware that I can tell which comes with the unit is the top channel which attaches to the window sash and the window lock brackets. Also do you recommend the removal of the unit from the unit frame during installation for ease in installation? I will post photos, but I am not sure how to do this. Thank in advance!
