One of the easiest things you can do to instantly start saving money on your heating and cooling bills is to get an automated thermostat. These smart thermostats will learn when you are home and make sure the home is at a comfortable setting during those hours so you're not cooling the house when no one is around to enjoy it. They also learn when you're going to be home so they can adjust the temperature before you step in the door to ensure your house is always comfortable!
Last year I replaced all of the thermostats in my house with the Nest learning thermostat. It learns your schedule to keep your home comfortable when you are home.
You can find it here on Amazon!
