PerfectAire window unit - unusual because it's made for a vertically-oriented window that slides side-to-side (rather than up and down as with normal window units). Works fine, we put a mini-split in the room so we don't need it any more. We've had it for many years, probably ~8 or so? All parts included for installation, except that you'll want to add your own insulation to fill in the gap above the air conditioner in the window (it came with a sliding screen that was woefully ineffective and we removed it and built our own).
