I was actually at canadian tire in vancouver and saw a r12 refill kit in the auto section. I thought they were illegal, but maybe you can try it.

Yeah, you can get them at CT now ... I don't think it's R12, it's some substitute that is compatible, but probably not nearly as effective. Beats no AC at all though!

Canadian Tire sells R12A kits, it's refined propane. It is more efficient than R12 and way more than R134a. I've used it on a couple cars and it works really well. R12A can be used on R134a and R12 cars.

Well that's good to know! Thanks for the real-world input.

what's R12?

it's a refridgerant used in older a/c systems. It had harmful effects on the environment so it's use was discontinued.

A newer / more efficient / more problematic (bcus it runs at higher pressures, causing more leaks) r134a is now being used.

It is still damaging to the environment but not as much as r12, for that reason r134a is only suppose to be sold / used by licensed individuals. and it's illegal to knowingly vent r134a into the atmosphere (althou no one polices this law).

R134A's thermal efficiency is lower so it is less efficient than R12. The REAL reason that R134A replaced R12is because Dupont's patent on R12 ran out.

So I should refill my R134a system with "R12A" found at Canadian tire and it's actually more efficient?

If you don't have a leak and your R134a system is working fine I wouldn't bother. You'd get colder air out of your vents and the system would be under less pressure if you did convert, but not like it's a night and day difference. It's good for people that need to fill up a system that has leaked IMO. I've read that the molecules in the R12A are larger and less likely to leak and if they do end up leaking it's not very damaging to the environment.
