Auxiliary heat uses electric resistance heating, which is much less efficient than your heat pump. Therefore, a heating system stuck in AUX heat will run up an energy bill. If you have a heat pump, it is best to increase your heat setting by only two degrees at a time to prevent your auxiliary heat from operating.
