Good question! It's hard to say.
We have one aircon for cooling and for mild heating, but once it gets colder we switch to kerosene heaters. Our current house isn't insulated and is a strange design that lacks roof ventilation making it an oven in the summer and a cave in the winter. Once we fix up the old house we bought, we can try out more efficient heating and cooling measures.
Anyway, I don't have a bill handy, but it varies dramatically by month. August is probably the highest usage when the aircon is on pretty much the whole month. The bill has a section at the bottom comparing usage to the previous month and also to the same month the previous year. I like to think we are doing good if we use less than we did the year before.
When the next bill comes, I'll try to remember to post it.
