Remember that you need different gauges for different gasses - or at the very least, adapters because they almost all run at different pressures, and you want accurate gauges, so need them to be reading the correct range over a large portion of their scale.

 

Fridge work is not hard, but it does require a methodical approach.

 

Gauges and a vac pump are not overly expensive, but carrying several different types of gas can be!. I have learn't a lot about fridge work fixing chiller units at cowsheds over the years - when it costs about $400 to get someone out between 5pm and 8am, or more in the weekend, I soon figured I needed to learn how to do it myself!. That being said, those are of a different scale to the gear used in boats ( 10Kw plus ) and I am not sure if the smaller gear would be easier or harder to work on. More fiddly no doubt.

 

And smithy, I ALWAYS replace the driers whenever I "open" the system, its well worth it. Liquid does not compress well, and any moisture in the refrigerant gas can cause a magnitude of problems which will not only stop the system working, but will cost a motherload more to fix than a drier. I even installed driers on my house heat pumps.
