Re: A/c fixes

Yes, you could convert to R134. Or you could use one of the R-12
substitutes, like R-406A (http://www.autofrost.com).

However, I don't think either of these will be cheaper than fixing
your current system. It all depends on why your current system lost
pressure.

If you need a new compressor as I did recently, they're "only" $250
from usadmc.com. (I say "only" because this *is* allot of money, but
cheap for an A/C compressor.) You may have a burst hose if it was
rubbing the body just right; the hoses are LONG and about $175 each. 
If you have a damaged evaporator or condenser, those are $400 - $500,
ouch. And you really should replace the accumulator/dryer ($170) if
the system was open to the atmosphere for a long period. I got these
prices online:

So if you must replace ALL of that, then you may as well convert all
the way. But trying to adapt the current system to R134 will likely
give unsatisfactory results. It runs at a higher pressure and is
therefore less efficient, but should get just as cold.

I agree that R-12 is not cheap like it was 10 years ago, but R-134
ain't free, either. All A/C shops should be able to find leaks
without using can after can of Freon (they're not allowed, right?)

I can check when I get home, but I believe that my recent A/C repair
done by a Delorean specialist was fairly cheap, $500-600 with a new
compressor and Freon charge.

What should I do? If I stay with r-12 and there is a leak, I could be
out some serious cash. but switching to r-134 sounds like the right
thing to do. any drawbacks.
