Followup question for those of you who have one installed:
What are the associated maintenance and repair costs for the A/C and its
related components?

I had one on my cherokee 140 (until I removed it). It was in-op (no freon)
and I didn't have a problem with the alternator belts breaking, so the
associated maintenance and repair costs were zero.
