The one thing to remember when converting from R-12 to R-134A is that you must change out all rubber hoses for barrier type hoses (Goodyear Galaxy for example) before the new refrigerant can be used. Not to mention that a new compressor would be in order since the above refigerants use differant oils, and you definitely don't want the two to mix. R-12 uses a mineral based oil, while R-134A uses a polyester based oil.

To make a long story short, either way you will be spending a fair amount of money no matter what direction you go. But for reliability reasons and performance reasons, I would stay away from tying to use a DC power inverter and running a small hermetic compressor on a 120V A/C system. By the time you obtain all the necessary parts you will still have a unit that is not meant to handle the vibration common in field equipment.

I've done many installs on everything from mining equipment to heavy ag equipment...and the most reliable system is still a PROPERLY installed engine driven compressor type system.

You will probably notice that your liquid and suction lines run up one of the vertical posts on your cab...this is the most common place they will leak...along with behind the compressor clutch. Check these out first.

Sorry for the long post, but it's better to fix it right the first time than to spend your money twice. And I've seen it done pleny of times.

Shoot me an email if you have anymore questions!
