Ac Refrigerant
Hi guys,I thought that this may be useful information. I was thinking that my supply of refrigerant is starting to dwindle, 134a specifically. The last time I bought was several year ago, when a certification card was not necessary to buy it. So, I googled if there was anyway to get certified online. Well, there is. it's a 50 question test that is open book and costs 20 dollars. It gives you certification in the recovery and recycling of the refrigerant under section 609 of the Federal Clean Air Act. This one only allows for MVAC (motor vehicle ac) use, but there is also a test for Section 608, which covers non-MVAC systems. I believe that it is also 20 bucks, but I am not sure about that. They told me that the time is about 2 hours, but that that can be extended. You must get 84% and that is 8 questions max to miss. I read the 11 page study guide, that they provide via pdf download, twice, highlighted some things, finished in about 20 minutes and got a 96%, that easy (your experience may be different ). One other thing, the end of 134a production is in 2021, so you may want to stock up, if you have a 134a system. Beware that the test begins as soon as you make the payment...Mark P.S.I am in no way associated with this organization, except as as customer

I was thinking recently of driving to Mexico to get R-12 again. My A/C was designed for R-12 and doesn't perform as well with R-134a. Here in the Peoples Republic of Commiefornia, you have to buy it in special cans and pay a $10 deposit on each can. You get your deposit back when you return the cans empty or not.

Is this a new thing federally or only in AZ?

Well,I learned something, you don't need a card to buy less than a 2 pound container. I buy 30 pounders and I do need a card:

When I rebuilt my A/C I got all new hoses, dryer and expansion valve along with a new compressor. I kept the evaporator and simply flushed it out. I put in PAG oil and the R-134a but I've been disappointed ever since.
If anyone has used one of the R-12 substitutes I would love to hear of their experience. I wonder if I would need to flush out the PAG oil and use something else.
What year did Dodge switch it's A/C to R-134a?

There ARE substitutes for R-12. How well they work is debatable. Some are flammable and contain propane or butane. Some are mixtures of other refrigerants which are not flammable AFAIK.

Many things make good refrigerants, like ammonia for example. I just posted what is LEGAL to put into your system. So, to some extent, what you put in your system is determined by your ethics...Mark
