We don't have double hung windows, so I looked around for a unit that would fit my bedroom window, and this unit, and the price, are an excellent buy. I knew as soon as I saw it, then ran it, this thing is solid.. my room is like a meat locker. Definitely recommend you buy...

Replacement

Unit packaged well and received without any damage. I had an old unit that went bad and this was a replacement. We pretty much just swapped them out since bracket holes were already drilled so we just put new hardware on and slide unit in place. Working well since.
