Thermostat Control to cut down electric bill.

[Kevin Boyd]

My electric bill during the summers is around $1600/month. It’s already been over $1k/month for the past few months. I’m sure my guests run the AC 24/7. When the doors and windows are open, when they’re gone for the day, etc.

What systems are available for shutting off the AC when nobody is home or if windows or doors are open? I don’t want to monitor it myself, I want it to be automatic.

Thanks!
