I can sure sympathize with the stories about older houses and heat/ac issues. I lived in Florida over 20 years ago and had an older house without heat. It was never needed, but couldnt have survived without the air conditioning. We had central air installed and gas logs for a fireplace (which had never been used either) I think we turned them on once or twice as a heat source. This was before my quilting days, so I cant comment on that!
