Well, this unit was originally $1650 without the line set. I figure I'll call a local contractor for a repair estimate, and also get a quote for a new system while I'm at it. It will be interesting to see what the contractor premium is.
Nobody installs Friedrich around here, but all these mini-splits seem to have a similar design. Installation is not that difficult if you follow the instructions carefully (and have a vacuum pump and R410A adapter), but you get no warranty unless it's installed by a certified rep.
Thanks for the advice.
