The easiest is to leave the heat at 62, lock the doors and enjoy Florida. Having someone walk through the house once every 14 days to run water in all drains (sinks/showers) and flush the toilets to ensure the traps don't evaporate is about all you need to do (and even that is probably not critical). A Wi-Fi enabled thermostat will give you piece of mind that the furnace is running as expected and even allow you to adjust the indoor temperature if needed. Depending on where you're coming from that could still be a reasonable heating bill but it's the easiest and most likely the best approach for your house. While not critical but for added confidence, if you're on a well - turn off the well pump and hot water heater. If you are not on a well but can easily get to the water main turn that off and the hot water heater. The water would need to be turned back on to run water in the drains - and then turned off again. If you have an instant hot water heater in your kitchen (or other) be sure to turn that off.

Draining pipes and lowering the temperature to a point where freezing can occur is a much more challenging approach depending on your house (slab, crawl or basement) and how low the temperatures get where you come from. If you've got a crawl space with pipes you'll need to be very careful. You never really know if you've gotten all the water out of all the lines and there will be some trepidation when you turn everything back on. I agree with the other posts, do NOT put antifreeze in any of your water lines.

Leaving the heat at 62 will cost the most over the winter but may actually be the least expensive in the long run. Houses don't like extreme temperature changes.

Welcome to Florida!!!
