You can buy the "drop-in replacement" refrigerants, but there's not
a whole lot of support for them in the service world outside of large
cities. Before you do it, find a shop in your area that can support
the system, do refills and diagnostics.
If you can't find a mechanic in your immediate area to do it for
you, you will be forced to figure it out yourself and buy some very
expensive tools (and some safety gear) to DIY service it properly.
Refrigerant Recovery machine, at least one empty 30-Lb recovery
cylinder, refrigerant filters for the recovery machine inlet, 1/3 Hp
oil ballast vacuum pump, electronic micron vacuum gauge, Recharging
Gauge Manifold and hoses, electronic leak detector, 50CF or larger
high-pressure dry nitrogen cylinder, nitrogen regulator, a couple of
direct-read thermometers, a big box fan for testing while parked (to
simulate winds at speed), assorted flare wrenches and special tools
and screwdrivers, Safety goggles and heavy gloves...
There's $5,000+ before you blink if you just walk in with a wish
list and get all new - $2,000+ even if you shop around for some
serious bargains and Closeout Sale prices, haunt pawn shops and used
tools dealers.
If you aren't doing it every day as a working mechanic, and/or
supporting a small fleet of cars, that's a hell of an investment for
tools that'll only get used once every two or three years.

Thanks for all your help. There is a place a few miles from my house
that said they will refill my ac with r12 for about $150.00. Does this
sound about right? Thanks Jamie >> Stay informed about: AC question? |

While you're at it, get the shop to put in new receiver/drier,
expansion valve (don't use that 20-year old valve), new seals, oil,
and re-crimp barrier hoses in place of existing hoses that are
probably shot. Make sure you use AC Delco if not OEM. Then recharging
the system for $150 actually sounds pretty good than several years ago
when I had to pay big bucks!!!

Also, make sure the shop uses REAL R12 and not a "replacement mix".
BTW, a can of real R134 costs $8 at Walmart. From the Interdynamics
web site:
http://www.id-usa.com/how_to_faqs_retrofitting.asp#25
"25. What about some of these "drop-in" Replacement
Refrigerants for R-12 that I have heard about? Are they any good?
The EPA points out that only R-134a has been tested and approved by
automakers for use in their vehicles, and it is also the only
Replacement Refrigerant for R-12 that is widely available.
EPA adds that there is NO SUCH THING AS A "DROP-IN", since
refrigerants CANNOT BE MIXED in an A/C System. In addition, ANY
REPLACEMENT REFRIGERANT MUST HAVE:
* Unique Fittings for the Service Ports
* Unique Charging Devices
* Unique Label
In addition, any replacement refrigerant containing R-22 requires
replacing system hoses with Barrier Hoses.
It should also be noted that some of the more talked about Replacement
Refrigerants are made from up to 80% R-134a. "

The replacement for R12 is R134a. R134a is not as efficient as R12,
therefore an R12 system using R134a will not cool as well. Systems using 134
are designed differently (larger) so that they acheive the same level of
cooling.
As a practical matter, the average Joe on the street is not capable of
installing R12 on his own and it is impossible for the average Joe to do
this legally. In order to have and use R12, a license is required. You can
go to the corner autoparts store and buy R134a, but as another practical
matter, you will not be able to load an empty system properly. The stuff you
can buy at rthe corner store is designed to maintain a serviceable system,
but you need to establish a servicable system, and this is an entirely
different matter. You need professional help to establish a servicable
system. (I also need help to establish a working system, and I can maintain
the system in a servicable condition using stuff I bought down the street at
the autoparts store.)
I suggest that buying refridgerant off of eBay is a misguided attempt to
save money. IF you had the skills and equipment to create a working system
where there currently is none, then _maybe_ eBay would be a good place to
shop, but I think you have significant hurdles that should be leading you to
professional help. >> Stay informed about: AC question? |

Yes.
It also sounds like a good place to ask what they would charge to rebuild
your system. They will do it without taking the smog equipment off.

Changing to R134a is easy.
Drain the oil from the used parts, Compressor, Evaporator and Condenser.
If your hoses are in good shape, they are reusable.
Pull the valve cores from the fill fittings and screw on the R134a fill
fittings, They should be steel R134a fittings, not the cheap walmart stuff.
Your R134a Retro kit will come with ester oil.
Add the proper amount called for that compressor to the compressor.
IBuy a NEW Drier.
Replace all the o-rings on the fittings with new ones from the retrokit.
Once its all bolted up, have it evacuated and charged with 80% of what the
R12's charge weight called for.
IE: R12 28 oz,,,,,,,, then R134a would be 22 oz
As the website develops, all this will be written up on www.bought4less.com
