OK, it was chilly last night, went down to 47F.

House stayed above 72 with no heat.

Temps will be up in the 80's today.

I normally keep the windows and doors closed due to allergies.

Is it less expensive to run the AC now when the house is 72F and the
outside temp is still below 60? (taking into account I don't mind the
house being down to 65 for the first half of the day) Or is it better to
wait until the house gets above 72F and the outside temp is 80F?

Whoa! Gotta turn off the ac now, it went down to 64 quite fast!
Hi,
If you have an intelligent learning thermostat(programmable digital),
it'll help you quite a bit. How is your humidity? Our blower is going at
lowest speed setting most of time. When heat ir collis called for it
witches to it's proper speed. I think this way it gives best comfort level.
