Many people still have cans on their shelf. I have a couple of boxes that I sell for $25-$40 per can on craigslist. Check your local craigslist ads. ---

I thought that they used propane. Either way butane is R600 and propane is R290 and they are both amazing and natural refrigerants. ---

I thought I read something recently about 134a now being replaced with something else. ---

You are correct. It is in early stages of being phased out. I think all new cars by 2020 will be using a different refrigerant. Some auto makers already made the switch. ---

Please don’t be offended . . . There is no way on earth, that I would buy a car where you converted the ac system to operate on butane or propane 😬 ---

I believe it is a criminal offense to do so. When the switch was made to R134 I was in Texas and learned there were several shady outfits selling propane kits to replace leaked R12. I was told to avoid those at all cost. ---

Switching over to R12434yf. About a hundred bucks a pound. Just had a 2016 Jeep and a 2016 Challenger both involved in crashes and had to have A/C done over destroyed condensers. ---

I have a 1982 Ford Granada that was retrofitted. Since the car’s AC was not originally designed for R134A, the air it blew was only marginally cool. It works, but it doesn’t blow the cold, crisp air like it did. ---

Did you read my earlier post . . . ? Did you have it correctly converted . . . only 80% of the charge, correct pop-off valve, etc. BTW . . . was the reason you had it converted because of a leaking component? [Previous page](https://community.cartalk.com/t/a-c-recharge-with-r12/93807.md?page=1)
