Quiet and energy efficient.

This Windmill air conditioner might cost more than others but it has an Energy Star which many other air conditioners don't have. So it costs less to use. It is also much quieter than other brands. It might have been easier to install but like all window air conditioners it is heavy and requires two people to set in the window.

Easy to put in with the extensions on the side fitting perfectly. Love the WiFi and it's quiet. However mine didn't come with a remote but I don't ahold of Windmill and they're sending one out!
