Freeze12 works very nicely for me. Much better than R134a and not much different than R12. The blend thing hasn't been an issue even though I've added 1/3 to 1/2 a can for the last 2-3 summers. Have had this system and compressor working for about 5 summers now.
Most folks knocking Freeze12 have never tried it. Nothing like actual experience with a particular product to kind of validate the opinion, eh?
I'm just sayin'........ 
btw, I will look for my pressure data tomorrow and report back if I can find it. You use the chart on the Freeze12 site and add 40 degrees to your ambient temp and go with those pressures. Seems like Al's high side pressure is about right with temps in the 90's, but I don't remember the low side being as high as 40. |
Jimmy,
You're playing with fire! As I understand it, Freeze 12 is mostly 134 and a small percentage of some Ju...., er alternative refrigerant. The reason for the alternative component is to help in oil circulation.
With any blend one component will leak at a faster rate than the other. That's why continually topping off is not a good idea. I would think you could get by with it once, but continually topping off could run into lubricant circulation problems. Since, as I understand, the stuff is so great and so cheap, then it would seem to make sense to recover and refill with a fresh batch. Of course finding a shop that will recover it will be a problem, but it beats losing a compressor and going through all the nightmares involved with removing the debris.
I just wanted to make sure that you are aware of this.
Good luck.
