Q. Is it more cost effective to maintain a constant temperature with air conditioning or turn if off during the day while I’m at work?
- Set the thermostat 10 degrees higher than normal if you’re going to be away for more than half the day. Your cooling will run less frequently, but your home won’t get super hot.
- If you’re leaving for longer than a day — say a trip out of town — then go ahead and turn off the cooling to save energy. If you have a programmable thermostat, you can set it to start cooling an hour or so before you return so you arrive to a comfortable home.
