Just like the title says. or someone who knows how to do R134 conversions PROPERLY.
lmk.
this is a paying job. but be reasonable.

the owner/operator of the truck is in danger of "melting" in the heat, so it will need to be done sooner than later. i won't be in TX until later this year, so I can do anything about it asap. therefore, I'm farming out the job. pm me their contact info. thanks !!!!When do you need it done? What is it on? I can’t fit much more work in the near future because my schedule already very full, but I know a couple good ac guys around here that could.
How about you? Get system evacuated (should be almost free for r-12 recovered or around $40). Open system to air (yes I said open to air) maybe add a few ozs of mineral oil if you think a lot has leaked out, fill with recommended amount of envirosafe and viola! you're nice and cool .
thanks.Pm sent
I would NOT open the system to air, and have never understood why on earth the manufacturer says so. I think it's because the average backyard tinkerer doesn't have a vacuum pump and they don't want to lose sales by recommending it be done correctly with the right tools...
Why admit humid air that will have to be dried by your desiccant, and make high-side pressures too high because air does not "refrigerate"? With a propane-butane mix, which is what Envirosafe is, evacuate the system and remove the moisture as with any quality job! Besides do you really want a system under pressure with propane, butane, oil AND air... the flammability of a few ounces of hydrocarbons don't bother me per se. I'm running it in my truck right now and it's working great. R-134a wasn't as impressive, and had higher high-side pressures, due to the old serpentine tube & fin condenser. For good really-hot-weather performance it'll need a new parallel-flow condenser (which means custom hoses to & from it), or a pusher fan turned on when the compressor is.
Too bad Towcat's not closer to southern MO, I'd help him do it for pizza and beer I even have a 609 card.
ps a viola is a stringed instrument like a large violin. I think you meant voilà
R-134a needs a higher pressure than R-12 (a few psi) to keep the evaporator above freezing AND needs more condenser to get rid of the extracted heat - which means more pressure on the high side. And is absolutely incompatible with the mineral oil the R-12 systems used.
