We absolutely LOVE our Windmill Air ACs. We have two historic houses, both of which don't have central AC. We've struggled to find ACs that work well, are efficient, and also look nice with our historic architecture. We've tried every portable AC under the sun – they don't work great, blow hot air and take up a lot of floor space. Enter Windmill Air! I couldn't be more thrilled – they were super easy to install (seriously, easiest install for any product I've ordered in years! They even include scissors!), and are really helping to take the edge off the summer humidity here in coastal Massachusetts. I've told everyone I know about these ACs because they've made a huge difference in us being able to enjoy being indoors in the summer. I couldn't recommend them enough! If you are looking for a beautiful window unit that blows some serious cold air, get these ACs.
