Hold a constant temperature on your thermostats. Programming your thermostat to go up or down will actually increase your energy bills and will make it impossible to balance the temperature from room to room.
Running the fan constantly will help balance the temperature from room to room and level to level.
In homes with a large amount of windows facing sunlight, it is common during the heating season for the temperature in the house to be higher than the setting on the thermostat. Turning down or shutting off the thermostat will do nothing to help because the heat is coming from the sun. Running the fan constantly, shutting the window blinds, or cracking a window will help this problem. The problem is caused by the house being built extremely tight and efficient. Older homes have large amounts of air infiltration which cuts down on heat from the sun.
Change your filter monthly. Clogged filters are one of the most common causes of furnace failure.
