What are the early symptoms of air-con compressor failure? I know it's a common fault, and now I'm paranoid. The system is working fine - cold enough to freeze the proverbials off the famous monkey, but I think I've detected a new noise...
It's quite quiet, but I can hear (with the music off!) a dry 'Darth Vader breathing' sound which stops when I press 'Econ'. Sometimes it cycles on and off for roughly a second at a time.
Please tell me I'm panicking about nothing.
