Also, does anyone here know their refrigerants?
I have a number of older devices including this machine that use the now banned R22 but after 30 or 40 years their charge levels are getting pretty low. You can still find small cans to recharge appliances but it's really, really expensive. The modern substitute is RS-44/R424A. It can be added to purged or partially filled R22 systems and you don't have to retrofit anything to use the equipment again.

Problem is that while I can find most other refrigerants and small can form for one or two use recharging I can only find RS-44 in the giant tank format which is really expensive and I'd never need that much refrigerant.
