I need to replace a 20-year-old through-the-wall air conditioner in my condo living room. (It was here when I bought the place 5 years ago). I'm basically gonna get all the BTUs I can stuff into my 26-inch wide sleeve. But I have a couple of questions.
--Is there any disadvantage to getting a 220 volt unit? I tested an unused 220V outlet near the AC and found it working. (As a bonus, I solved the mystery of what one of that unlabelled circuit breakers in my box is for.) The big attraction is that the AC would be on its own circuit with a 20 amp breaker.
--If I go with a 110v, how many amps can I safely go up to? The circuit's on a 20 amp breaker, but there's LOT of other stuff on the same circuit. The whole living room: TV, Tivo, stereo amp, 4 lights. I've never blown a breaker so far, but I don't have any easy of figuring out how many amps my current unit sucks up. So what should my margin of safety be?
