Should I set-back my thermostat?
It is alright to setback your thermostat a couple degrees (1-4 degrees) if you are going to be gone for an extended period of time (gone for over 8 hours, going on vacation, etc.); however you don’t want to be changing your thermostat setting back and forth all the time. On the contrary to what many public service companies say (such as utility companies) setting your thermostat back for short periods of time will cause your furnace to run longer when you want to turn it back up, which takes a lot of fuel and energy. Doing so will actually cost more than if you where to leave your thermostat setting where you normally set it while you’re home.
