probably depends on how meaningful the cost of utilities is to you. I try to use AC and heat sparingly just because I hate the idea of waste; it really annoys me if I have to turn on the heat a few nights later because I turned on my AC too early. but my whole utility bill is ~$70/month. I don't really care too much about saving 10-20% of that.
