From an energy-/cost-saving POV, is it better to ramp down your AC to a lower temp when you're not in the house or using the space, or turn it off completely and then crank up when you're back? What about, say, if you're away for a week or more. I know this is not like heat where pipes can freeze if you turn off. I should know this by now but I don't. Thanks for any advice.
