If you prefer a window air conditioner over a portable one, consider the GE 8,000 BTU Smart Window A/C. The unit arrived packed securely in styrofoam and almost fully assembled, with only a few parts aside from the main window unit. Overall, installation was straightforward but not quite as easy as the July window a/c I have in my bedroom. I have the window a/c installed in a 100-square-foot room I use as an office and second bedroom when I have a guest. Final ThoughtsThis GE window a/c cools fast and provides a lot of relief, even when I’m only using its powerful fan.
