It's an older house, probably 30 plus years old. VERY easy
to have saggy horizontals.

Is it (typically) easier to pour antifreeze into the pipes,
or blow the water out?

That's my concern. Might be horizontal pipes with sags.

A 1/2 inch pipe that is run more or less horizontal but is
3/4 inch
higher at one end than the other is enough to cause a
disaster.

Now think about how easy it would be for that condition to
exist!
