what is more expensive to have in you apt, gas heat or central heat?

Question

and also in the summertime is it more expensive to have air conditioners or central air. I'm moving into an apt with central heat and central air and i have never lived somewhere with this, i am concerned about how high this is gonna be ?

Answer 1

Gas heating is certainly cheaper, but only because of the current oil situation. If there becomes a problem with oil supplies, prices will rocket. While this will affect electricity prices too, areas receiving power from nuclear fuel will be more stable.

Answer 2

I think that gas heat is cheaper than central electric heating.

For air conditioners, they are both run by electricity; however, I think that central cooling is probably more efficient than space (room) cooling.
