The most common failures are leaks, which are fairly easy to fix, if
not cheap, but a compressor failure these days almost always means
changing the condenser to get rid of all the crap sitting in it --
which stuff will promptly wreck a new compressor.
My friend Hans always installs a filter if he has to put a new
compressor on, and they still sometimes croak from dirt. It's nearly
impossible to flush the evaporators since they are multi-coil units,
and the partially clogged coils won't flush.

Is there a max pressure at Idle?
The modern AC system is deceptively simple. It's rather elegant
engineering, which means that it's more complex than it appears.
It's all about fluid dynamics, with phase changes thrown in, and
a lot of weird plumbing. Testing is done by pressure gauges,
thermometers, and inference, yet an important variable is the
amount of fluid flow, both gaseous and liquid, for which there
is no direct measurement.
In electrical terms, it's like trying to diagnose a battery/starter
problem using only a voltmeter and your brain. That's what most of
us do and it certainly works, but it's _so_ much easier to _also_ use
an ammeter to measure the current draw rather than trying to infer it.
