Get a programmable thermostat.
Does your home really need to be the “perfect” temperature while you sit far away at work? For a $30 investment, you can save yourself over $100 a year! Programmable thermostat’s allow you to let your house get warmer or cooler that you might prefer when you’re not home yet kick on in time to have it just right when you walk in the door. Once you get your programmable thermostat, try taking it easy on the temperature. We usually keep our house about 78° F in the summer and 70° F in the winter (and open the windows in the Fall and Spring), and have found that if you keep a fan going (which uses far less energy than an HVAC system) to circulate the air, those temperatures are quite comfy.
