A programmable thermostat could save you money.

In heating mode, reducing your thermostat setting by one degree for eight hours will save about one percent on your heating bill. In cooling mode, each degree you set your thermostat above 75°F saves
you three percent. A programmable feature makes it easier for you to adjust the thermostat settings when you are asleep or away. If you already change the thermostat settings by hand, the programmable thermostat may not save you money, but it could make life more convenient.
