Any one know anything about A/C?

Again, no intention to flame, just discussion...

Define "air" molecule..  Oxygen, Nitrogen, Carbon Dioxide, Argon, etc, 
etc, etc?

Yes, I've heard that R-134a is smaller and that's why they had to go to 
better sealing systems to avoid leaks (besides compatibility with PAG, 
etc)...

That's interesting though that 134a might be bad but 12 may not be...

I've heard an awful lot of people say that the switch to 134a was just 
a big money making thing, but I've always been hesitant to accept what 
I perceive as paranoid conspiracy theories, I don't think people in 
general are smart enough to pull off something that big and keep it 
under wraps.  We can't even hold on to military secrets that are 
protected by law.

But I'd certainly be curious to read about it in Canadian 
literature/news if you came across it...

IIRC, it is because R134 IS actually bad for the ozone, while R12 is 
not.  Some
more details I have just found...  R134 molecules are 20 times smaller 
than R12,
and R12 molecules are 20 smaller than air...  If indeed R134 is 
smaller, then
you could argue that R134 is more likely to leak, and when the system 
sees a
vaccum after cooling, that it would be more likely to suck in air (and 
with air
here, it would have moisture in it).  Perhaps that is the reason why 
failure is
common, but not in VWs alone...
