You should not turn your furnace off in a cold climate, especially if the home is unoccupied. If the temperature drops below too low, the water in your pipes may freeze and expand, breaking the pipes and causing flooding. Without anyone home to notice the problem, the flooding can easily cause tens of thousands of dollars of damage.

Or you could just drain the pipes, too...
