After I found out that I needed to have a licence to use the new Freeze-12 refrigerant I decided to get one. Went to a site on the web at http://epatest.org/. They have the 609 EPA test online along with the study guide. You can take the test on-line for $19.95 with your Visa card. It is an open book test and they even have a link to the manual, which has all the answers in it, from the test page. My recommendation is that you read the entire manual first and then take the test. It should only take you about 30 mins to read the manual and then about 10 mins to take the test (only 25 questions). I tried to take the test without reading anything and looking up the answers in the manual as I went along. It took me a little over an hour to do it this way.

After the test they give you a temporary licence (you print the screen) and your real licence will come in the mail within 30 days. That's all there is to it. Don't need to be a certified mech or anything.

Going out to buy a bunch more Freeze-12 now and service the rest of my fleet. I'll let you know how I make out.

Also I found an interesting product that might be a good alternative to conventional A/C for some of our folks in a dryer climate. It is called a swap cooler and they used to make these for Bugs and older Buses back in the day (now Rocky Mountain sells reproduction ones if you are interested in them). This company is at http://www.swampy.net/hprices.html (this is thier price page. Go here first because there is no link to it from thier home page. Wierd, eh?). They are basically units that blow air over water for evaporative cooling effects. Not too expensive if you are facing a major A/C repair or retrofit. The only thing that I think is a hold up on these being a really super good idea is the amount of amperage the fans draw. It seems to be pretty substancial and might wind up costing you as much horsepower/fuel economy as an A/C compressor (with the added load on the alternator). Let me know if you folks know anything about these or have any comments. Talk at you later. Ken Wilford Van-Again John 3:16
