comment How much less power does a three-phase A\C unit use as apposed to a 220v unit?
@Tester101 The building in question is a 35-unit apartment building with seven retail spaces. The three phase may have ben installed for the washers and dryers, which are the only things currently using it. The AC is for a common area of that building, with lots of people coming and going.

Less amperage seems like a good thing, but I'm really concerned about wattage, because that's what I pay for every month.

Conversely, if three-phase did not provide a significant benefit for a 5 ton system, why would manufacturers bother to make both three-phase and single-phase versions. I mean, they do for 5 ton, but not for 3 ton. I have three phase service already, so there is no additional wiring cost to use three phase.

Right, but as that air settles down, losing energy to friction with itself and the walls, won't it get converted to heat? Where else would would that kinetic energy go?

I found that article too, but I did not find it sufficiently informative to tell me what I should do in this specific situation. Also, that article seems to be written for a professional audience, which I am not. Thanks though.
