Hello:

Moved into a house that has an attic locatedsplit type of air conditioner to
feed the upper level.

Attic is really low, so it's very hard to see, or crawl around in there, to
investigate.

This is a typical tri-level (split) in New England (30 yrs old).

For these attic mounted evaporator sections, that apparently have a blower
as part of
the system, does the blower "typically" use attic air, or do they
"typically" have
a duct, somewhere, leading to the outside for air intake ?

Thanks,
Bob

They just recirculate room air, so there is a 'return' or duct
somewhere that is bringing in the room air to condition it and send it
back out again after its trip thru the evaporator.

I've never heard of one using attic air.
