Question by real_ki:
With Central AC, does it save more electricity to leave them on always or set to auto?
I have a central A/C unit in a two story house.
We usually set the temperature to 80F and set the fan to “Auto” which basically turn on the fan and the cooling when temperature goes above the set temperature.
There’s also “On” setting for the fan which will keep the fan running always and I assume the cooling too maybe?(or maybe the cooling is turned on when temperature goes above the set temperature).

Which will save more electricity? Setting the fan setting to “auto” or “on”?

Obviously “auto” consumes less electricity. “On” overrides the system, forcing it to stay on all the time.
