Replacing AC, R12 to R134A, parts needed?
My 1980 240 air conditioner has about had it. I've recharged it and it still does not do the job. I would like to replace all the air conditioner parts with parts made to support R134A. My idea is to replace everything needed for R134A and have a professional lube and charge it. Can someone tell me what parts I need to replace in order to make my AC R134A compliant? Do I need to get into the dash, because that's a -----? (replaced my fan motor earlier this year).
Thanks, Mike

Hey Parrym, changing out the fan motor is a pain. I think this link will help you out. I've heard this is a good kit to use for the conversion. I've actually also heard negative things about it, but nothing bad enough to keep me from posting the link. This is a cost and time effective way to convert your AC. I believe they sell this kit at Walmart as a matter of fact. Good luck! Let us know how it goes!

Also, here is a link to the manufacturors "how to" guide for their product. This may prove useful before-hand, knowing what is involved and all.

After surfing around, it sounds like I should really have it vacuum tested first before I go to the expense of replacing parts. I presumed that being 25 years old and never having been replaced that the compressor was going bad (sounds pretty loud after running awhile). Thanks for the posts, there is some good information here. My biggest fear was going into that dash again... I think I will stick with the R12. That way I don't have to upgrade anything to support R134A. I have also heard there are some R12 replacements that do better then R134A, I will research that also. Has anybody heard of the R12 organic replacement?
Thanks
Thanks

I haven't heard enough to post about it. I know that R12 has become quite expensive. You should be able to "borrow" a set of lines/guages from Autozone with their loan-a-tool program. I've been told you can at least. Might be worth looking at.

Update: I finally broke down and had a mechanic look at my AC. Turns out everything is ok with the exception of very little coolant (despite me trying to add a can). They vacuum pressure tested it and put in almost 3 pounds of coolant (That stuff cost $70 a pound!!!!!). Cools good now, not bad for a 25 year old AC (hope it holds up).
Thanks for your input!
