There are no leaks in the system (checked with the probe thingy), and it get's cool, not cold, so I suspect it wasn't gassed up to optimum pressure initially and that's what's causing the noise.
If this is the case, can you recommend somewhere I could get a top-up of the older R12 gas for a reasonable price?
