Being that we are part timers and the last time down ran the AC, when should we turn on the heat ?? When we left, I set the thermostat to 82 Degs
for the AC, but didn't think it would get cold so soon. I thought we would be back long before that, but I guess not

. We have friends looking after
the house and will change from AC to Heat, but where should the thermostat be set since we are not there. I was thinking 45 Degs !!!
Your thoughts would be greatly appreciated.
