I do have it in the sump which in my case is my largest water volume due to it being a stock tank. I also have a little coralife temp on the display and it runs 1 1/2 degrees hotter than the sump does. When the expansion modules come out I'll switch that one out. I hang that probe into the overflow. My thinking on that is that the water coming off the surface (closer to the lighting) is probably the hottest but I may be wrong on that. Close enough though. But maybe you could hang the AC unit's temp probe in there.
