I just picked up a renix today and saw that the AC has not been converted. Does anyone know how much the conversion costs? TIA

AutoZone sells a conversion kit. I'm thinking of doing it too but don't know if anyone has tried it. I don't think it's a big cost to have the work done but you have to vacuum/remove all the old oil etc from the existing A/C system before they can put in the R134A because of compatibility issues.
