Speaking of refrigerants, you can replace R22 directly, R134 sometimes directly but desirably with new oil and capillary, and probably other refrigerants with... R290 - an innovative compound that is very environmentally friendly and cheap. Also known as Propane.
I've done it with my home office room A/C, a small 12,000 BTU unit. I couldn't believe it when I found out you can do that.
They say R290 is cleaner, purer, blah blah, but the gas from a simple propane tank you can get anywhere works fine. Remains to be seen for how long, so far 2 summers and going strong.
