[AT] Air conditioner question

[Rupert]

Hello Steve,
	Have you seen this 
<http://consumerproductsworld.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=CPW&Category_Code=REDTEK>? 
Is it true? Looks like the EPA is shutting down the use of R134a so that 
leaves us with the RED_Tek types of refrigerants. I was planning on 
tooling up to work on the R134a systems but this article makes me think 
twice.
	Thanks for the info on the Freeze 12 and Enviro-safe refrigerants.
