What is the approx. total weight of freon that the A/C system takes in the R12 type?

I'm going to try Freeze 12, but they say you're supposed to use only 90% of the weight of the R12 that is normally required.

 

I got the answer: 2 lbs.

That would equate to 1.8 lbs (28.8 oz) of Freeze 12.

 

Thats funny that your still aloud Freon in usa. they have banned it in Canada so as to meet some environment regulation.

 

Yeah, I wish I could use Duracool which is a purified propane refridgerant and works supposedly as well as R12 and better than R134, but it is illegal to use here in AZ. I guess it has to do with being flammable, but so is the 19 gallons of gas I'm able to carry around. In an accident, I'd much rather have a few seconds of propane burning off over a liquid fuel fire.

I'm probably over-simplifying the whole thing, but it seems like Duracool would be the way to go if you still have an R12 system that needs to be charged.

 

when i put freon in my system down here after Canada, it made a BONE CHILLING difference, quite literlly! it was like winter inside my truck in Belize!
