Turn off the AC if you're leaving for the day
If no one in your household will be home during the afternoon, turning off your air conditioning before you leave in the morning will save energy.
Step by step:
- Turn off your AC on your way out.
- Unplug and turn off devices. For example, DVRs, cable boxes, and game consoles can use a lot of electricity–even when the TV is off.
- Turn your AC back on when you return. Your house will cool off much faster than you might think. If you have a programmable thermostat, set the air conditioning to turn on after peak hours.
