anyone who turns heat competely off is stupid or in for big surprise

the large temp swings make the plaster drywall seams crack, expansion
and contraction, big chunks of plaster WILL fall from walls.....

plus low areas of pipes can still freeze, cracking pipes that may only
show up later after water is on for awhile

any appliances with water washer, dishwasher need winterized too

Above two items would be my concern. I'm not sure what these winterizing
services do/recommend/advise/guarantee. Maybe they don't even winterize
that far north.

easiest and safiest, leave heat low but keep home from freezing,
houses are worth big bucks why risk it?
