AC experts jump in here!

There are R-12 substitues that work well. We use a product called freeze 12 that comes in 1lb cans. I use it in my car with great cooling efficiency. Costs us about 5 bucks a can. Better alternative to the 134 conversion.

Bernie, i have read about Freeze 12, and a few other products. where do you get them? i have not come across them locally.....and do you need a license to get it? i recall thinking there was a reason i did not pursue that option, but dont remember if it was a chemical/operating reason, or simply that us normal folks cant get it.

We get it from one of our suppliers. He should be in tomorrow and I'll ask him. I'll let you know when I find out.

I tried all that everyone is talking about, Finally I found out that I had a leak in the back of the compressor. In my case I replaced switches and clutches and everything worked fine for a few months then weeks with the next quick fix. I even dropped the cash and bought R12 to try and refill my system. Finally I found a AC shop early in the morning that checked my system for $10. Thats when I found out I had the leak. I'm all for the quick fix and hope that your problem wasn't as bad as mine. For $10 to know the problem then fix it, opposed to 300+ on new clutches, pressure switches, and Freon. I wish I would have just went to a pro. Oh before I go, I switched over to r134a and its cold again. Aeromotive even makes stainlesss braided A/C lines. Iwish I found them before I had all the work done on my car. Good Luck trying to find your problem.

Dude, what part of the country do you live in? 10 bucks? We charge an hours labor to fully diagnose the system, recharge, install die and then check for leaks. Comes out to about $100.00 p&l. Don't know how those guys are puttin' food on their table?

Hey thanks Bernie! i know a few of us will appreciate knowing if we can get our grimey mitts on that stuff.

what is the main ingredient in this "freeze 12" there are some products that are actually compatable with r-12 but they can be flammable and are only recommended for use in tractors and non mobile units, I'd be interested to see what is in this stuff. and "89saleen" you got me there on the vacuum test, I forgot about that.

Sorry, not sure what's in it. If I find out I'll holla' back. Just gave my car a "shot" of it last week and works great.
Gotta' like the google search:
Freeze 12

Big J, thanks for the nice link. good site!

Not trying to change your mind, but here's my $0.02 on Freeze 12 (and any of the other blends on the market). Freeze12 is a blend of 80%134a and 20%142b. The claim that it works better than r12 is not true. As a blend you could get better cooling than r134a because the r142b contributes to cooling and produces a little temperature glide in the condenser. However it must only be used in a Leak free system. Installing a blend like freeze12 in a leaky system could cause compressor failure because the 142b leaks out first because the molecules are the smallest. The 142b is the only gas in Freeze 12 which is capable of carrying mineral oil in your AC system. No 142b in the system = NO MINERAL OIL BEING MOVED. Remember, pure R134a systems don't use mineral oil because R134A will not carry mineral oil (R134A systems use PAG oil since R134a is designed to carry PAG oil.) No oil = compressor failure. Blends must not be topped off, they must be evacuated and recharged into a vacuum. More importantly, 142b is a flamable gas which opporates at a much higher head pressure. If your compressor locks up (as a result of no oil as mentioned above) and overheats it could very eaisly ignitie the 142b gas with devistating results to your engine bay. That's why all the major auto manufacturers use pure R134a. R134a is non-flamable. Manufacturers don't want the liability resulting from a fire triggered by 142b. In addition, very few A/C shops will service your system if it's filled with anything other than R-12 or R134a. They don't want your blended gas contaminating their R134a or R12 during recovery. If you do decide to go with Freeze 12, MAKE SURE you put the proper labeling stickers on your A/C system as instructed in the Freeze 12 conversion kit. Otherwise you may be liable for any contamination resulting from A/C recovery of your blended gas. Just my $0.02 Good Luck.
