You're in FL, I didn't think you needed a furnace!

In Mich, turn it down 6 degrees or so when not around. It's not harder on the system to do this, actually easier IMO, less starting and stopping. The savings is due to the less temperature differential between outside vs in when the temp has dropped when away. Less temp diff = less heat lost.
