Which uses more power to fun, Air Conditioning, or Heating?

I live in Orlando, and Usually the air conditioning is on, but some times of the year we have to put on the heating. It seems the months that we use both heating and air conditioning, our bill goes up. Does anyone know which one uses more energy to run?

1. If you're talking about electricity cost, Heating will cost you more to run. Let's say you have electric central heating and electric central air conditioning. typical heating furnace (electric) runs at 7 to 8 Kwatts/hour, when air conditioning runs at around 3.5 to 4.5 kw/hr. I don't use air conditioning in the summer at all to save energy. I just use fan. and in the winter i don't use my electric furnace at all. i just use 0.9 Kwatts/hour oil heater just for my bedroom. good enough for me and save me plenty. i live in denver, colorado.
2. Is you furnace run on electricity or gas? AC is all electricity. That's why the bigger units are run off 220/240 volts. A gas furnace runs on 110/120. And the power only runs the fan and components. If you have an electric heater, maybe.. Otherwise, AC uses much more power.
