The Windmill AC unit is simply put, the best AC unit I’ve ever owned. Easy to install, fits in most all windows, the app just makes life that much easier. It’s quite, sleek, and cools better then any unit I’ve previously owned. I would strongly recommend this to all who are looking for window units. I’ve already purchased a second unit for my Sons room. Customer service in stellar, friendly, kind, and super knowledgeable. JUST THE BEST ! Thank you Windmill team for bringing such a good product to market! Can’t wait to see what’s next. I am a windmill customer for life. Keep up the GREAT WORK!
