Since we were under a heatwave I decided to purchase a newer window mount A/C unit. The mounting was very similar to the old unit we had. So it was easy to install.  One word of note, if possible a person could use some light chain and on both sides of the unit and screwing a wood threaded hook into the overhang on the roofing edging, only if safe or possible to do this. 
I am not super crazy about the WiFi operation of the unit, I prefer the old fashioned my of operation the unit with a remote, so the remote works fine. 

The unit really took to sting out of the heat and made our living room, kitchen area comfortable.
All and all very pleased with the GE unit, I would recommend and purchase other products in the future!!
