I love my new Windmill AC unit! Delivery was a breeze. I used a TaskRabbit for installation, and the person even mentioned how simple the process was. You don’t need to purchase anything else, comes with cardboard to fit your window unit perfectly (and with a much more pleasing look than those plastic window extenders). Works exactly how O expected: powerful, easy to use, and quiet! Multiple friends have complimented on how nice it looks. I haven’t set up the app for remote control use, but will do that soon. Highly recommend!
