We wanted a window unit for our 1972 split level home! Our bedroom is the last room in the house, with only one AC unit. We didn't want to go through the hassle of installing a second unit, BUT I HATED the look of all window units. Then we found Windmill! WOW. It looks amazing! You can't even tell we have a unit. It really was a "breeze" to install like they said! You won't be disappointed. Finally we can sleep without sweating all night!
