LG 8,000 BTU window air conditioner, model LW8016ER. I purchased this brand new and used one season then put it back in it's original box since we moved and the current house has side sliding windows. It is designed to sit in a window opening with over-hung windows (note, up and down, not side to side). See the below Home Depot link for specs, but it's for a window minimum opening of 22" (max 36") and minimum height of 13" (max 36"). Perfect for cooling a bedroom or living room on these hot days.
Thanks for looking!
