A/C works pretty good as a dehumidifier, imho.  
 
My thermostat's set at 78.  North TX, we've had pretty consistent 100+ days the past few weeks, down to high 70's/low 80's at night.  Warmer than usual at night......maybe the earth really 
is in a warming trend??  :hmm:
Anyways, with ceiling fans on (and an extra floor fan in the office), keeps it pretty comfy, especially as I'm sitting around in shorts.  Electric bill for the past 2 months was $155/165, which I consider pretty good for a house that's just shy of 1800 square feet, with single pane windows and no drapes.
For winter, I'll keep it at 70.  :awe:
