Running the compressor in an air conditioner takes a whole lot more electricity than running a blower fan to move air across some gas heat. If you wanted to break the whole thing down into physics, I'm not sure exactly how it would go, but at least in terms of market prices I can assure you it is much cheaper to heat a home with gas from 40 degrees F to 70 than to cool one with A/C down to 70 from 100.
