Followup: this ended up being about 2 hours of honest work, after probably 6 hours of fretting and research.
All in, $1100 for the stuff, of which probably $100 was unnecessary: https://www.pioneerminisplit.com/col...nt=33169173264
I did end up getting a proper vacuum pump and manifold gauge set, instead of using the compressed purge chemical I bought from them. $130ish. I’ll help a couple friends install their mini-splits, then it’ll go into my composites work.
EPA certification ended up unnecessary, since I had no refrigerant leaks.
Filed for Xcel to give back $300, and will file for another $300 of federal tax credits.
It has been fantastic having a heated and cooled space. Haven't been through winter yet, but freezing evenings have been fine, and power draw has not exceeded 1kw yet, in cool or heat mode.
