This AC unit has done so much to save us over the last couple of years. We live in the Puget Sound area, and it feels like each summer gets worse and worse in terms of heat, and none of the rentals we've lived in have any sort of installed AC. We finally purchased this unit, and it is one of the best purchases we've ever made. It's relatively easy to install and move around. The only downsides we've ever encountered are how loud it can be while we're trying to sleep and the window mount doesn't completely fit our current windows, but neither of those are deal breakers (especially since our current windows are EXTREMELY tall. All in all, a great purchase.
