According to published specifications, the 12K BTU AquaAir S*R-16 models draw 10.4 amps @ 115VAC or 1051 watts. The water pump will draw an additional 1-2 amps, depending on model.
To get inrush current, you'd need a clamp-on ammeter with inrush capability. The min/max setting won't tell you true peak amperage (you'd need something more sophisticated for that), but would give you an idea.
Many modern rotary compressors have a fairly low in-rush current demand, dampened somewhat by start capacitors. For example, my 16,500BTU Flagship Marine A/C draws 14.1 amps at full load, and the starting current requirement is only 21 amps.
Your mileage may vary, however :-)
