I have a oustide hose spigot that is one floor (+/-) higher than
another one and they are at opposite ends of the house. So I've been
blowing it out through the high *one and out the lower one. *I leave

The first time we winterized after buying the place, paid a plumber
$25 to do it and followed him around. IIRC, he said to set the
compressor around 70.

Blowing it out from high to low sounds like a good idea.

The other thing the plumber did, that I thought was a good idea, was
to pour a cup or 2 of RV antifreeze down all the plumbing drains, and
into the toilet tanks and bowls. Didn't see you mention that anywhere.
