If you have the heat on in the morning and AC in the afternoon, your home is horribly under-insulated (or you are trying to keep in way too small a temperature range).

Old homes tend to not have any insulation. Parts of my house have modern insulation due to renovations/additions but other parts not so much. I wouldn't swap out the original windows and glass on the facade, for instance. And insulating it would probably be a destructive action as you need proper vapor barriers for insulation to not rot your home.
