I am surprised that no-one has yet commented on the obscene prices rises of the above refrigerants lately.
Never mind the stock piling of R22 if I had known what I now know. I would of saved the above.
407 has risen 50% in the last 2 months alone.
With lots of lame aaaaah! well the refineries are having problems!
Rip off time more like!
Oh yes and the gradual reduction is recovery cylinder charge amounts is another one.
Explain how you can purchase to Identical cylinders.
1) New with approx 60kg charge.
2) The same size empty can now only hold 45kg?
Even the empty cylinders (whether to be used as recovery or receivers) are in short demand.

Am I missing something?
