Hey,I never said R290 was the holy grail of refrigerants did I?I just said it is a cheap refrigerant(8 bucks for 30 pounds).And it is damn cold.

R134a is NOT better than R290,I have used both.R134a is a medium temp refrigerant.R290 lacks molecular weight,that is why it doesnt perfrom as good as say R22.If R22 wasnt so expensive I would be using it,trust me.But I ran out of R22....
R290 definitely owns R134a!

So your telling me propane is banned where you live?

I know r290 is not legal to be used in commercial refrigeration,but in DIY it does not matter.
