Converting factory AC to use R134a

[Lurayfarmer]

I've done this switch on several vehicles. The key steps are changing the charging fittings, changing the oil, thorough evacuation, and recharge. It is a good idea to change the receiver dryer which is a cheap part. A reputable shop can do this work for a very modest price. Forget anyone who wants to mess with the compressor, valves, hoses, seals, etc. That's just a way for a shop to take money out of your pocket.

As to cooling performance, I've checked vent output temperature with an AC thermometer. It's very close if not identical.
