I'm not talking about what the window unit is actually "rated", but rather measurements I have taken myself. I've never seen it go over something like 412w on a hot day, though I have not done extensive testing on this. I'm just assuming it is actually doing the 5k BTU of cooling it claims because I can't really measure that.

My temps aren't that extreme though, summer highs are usually in the mid 80s, but lows often don't go below upper 70s. Humidity is the big killer. I live next to a lake and it might as well be like an Amazon rain forest in the summer. I'm hoping if I lower the humidity inside I can keep the A/C a little warmer and still be comfortable.

I'm super curious about playing with a liquid desiccant for dehumidifying and drying it using heat pump reject heat...but that's a whole different topic...
