yes, you were correct
Yes, you were correct about that outlet once being a 240 volt, I would have never thought of that, just curious, what made you suspect that? Have you seen a lot of apartments where that was the case? I'm guessing that whenever it was turned in to a 120 volt outlet, whoever changed it just used the ground wire as the neutral, I'm not sure what the second hot wire was doing all this time, I guess just sitting there, but the electrician had no problems turning it back in to a 240 volt outlet, he did not have to drill a single hole or run a single new wire, I'm guessing everything he needed was already there and it was just a matter of putting the wires in their proper place, works great, and the quick 220 power supply works great as well, I would definitely suggest that if you need 240 volts and don't want to install an outlet.

Dude, tons, TONS of older apartments and houses have added-on dedicated outlets for window air conditioners. It's extremely common, especially in Chicago, a place that's temperate with hot summers. And especially on buildings that have been fitted with central air conditioning, those outlets are almost always converted to 120 volts since they are no longer needed. The fact that it was below the window in a main room like the dining room, and since you also said it was on its own breaker, it was a dead giveaway.
