Hisense (115-Volt) Portable Air Conditioner (vent thru window)

Bought this at Lowe's new back in summer of 2018 to cool master suite in home while waiting for AC man to catch up and replace my main central AC compressor when it failed at the worst time. Used once for a few weeks, then stored in closet since. Cools 400sq easily... I cooled a 1500sq two story house with two of these during summer 90+ heat to 75F or so, with fans circulating and all lights and heat generating appliances off. One upstairs and one downstairs, and the two bedrooms where installed were almost uncomfortably cool (65F in the room where they ran). 7500BTU DOE or 12000BTU ASHRAE New equivalent runs about $450-500 if you can find one in this heat wave.
