Finally hot enough to set up the AC unit. It was very quick and easy to get it up and running. The only mildly challenging aspect was figuring out the best way to place the window panels and included foam seal so it was relatively solid and wouldn’t leak hot air back into the room. I have vinyl sliders and placed the foam seal on the outside edge of the slider up against the bug screen. Once set up, it cooled our medium sized room to 68F in less than 10 minutes. The fan is a bit loud even on low, but that doesn’t bother us as long as it cools the room.
