That’s a shame, because managing the temperature of your home with a thermostat is one of the easiest ways to save on energy bills. If you use it correctly, a thermostat will pay for itself in the first year you own it.
The question is, how do you use a thermostat correctly?
Here are some suggestions, courtesy of the U.S Department of Energy, that will give you an optimum balance of comfort and savings.
When you’re home and awake, target a temperature of 68°F.
Lower temperatures by 10° for the hours you are asleep or out of the house.
Remember that turning the temperature to a very high setting will not heat your home any faster; it will only burn more fuel than you need to get the job done.
When you’re home and awake, program air conditioning to 78°F.
Program the AC to shut off during the hours when you are not home.
Program heat or air conditioner to shut off 20-30 minutes before you leave; return the temperature to normal comfort levels 20 to 30 minutes before you come home.*
Program reductions in heating or cooling to begin 60 minutes before you go to sleep; return them to normal levels 30 minutes before you awaken.
* If you have wi-fi / wireless thermostat, you can control your home’s temperature from your smart phone.
