EDIT: Side note, don't let the south fool you. We get below freezing very often. We thaw out during the day, but we freeze nearly every night. And 8 days of snow last year. Whoo hoo.

But, it's not getting very far below freezing and as you pointed out, goes above freezing during the day. That may not even be enough to cause issues.

If it sits unused for any length of time, just blow out the lines, pretty easy and quick, which will give peace of mind.
