Moaning aircon

[tracer.smart]

My aircon's noisy, but it still puts out cold air.

It's always been a bit noisy, so in Jan this year I had the evacuation valve renewed
and system regassed at Camtune, as well as all the belts and bearings checked.

However when the weather necissitates using it, it's still quite noisy from inside the cabin. Set to 'Lo', the noise can be described as a pulsing whir, usually starting with a bit of a thump as it kicks in and spins up to speed, and it's louder than the radiator fans if they happen to be running.

Should I expect it to be noisy or is there a problem diagnosis anyone can offer?

Mine sounded awful after getting re-gassed when very low. I had it re-gassed again and they said it was still lower than expected. Maybe if your coolant is getting low it's struggling

Mine's also noisy both pre and post it's recent regas. Pumps out cold air (thought not exactly freezing) still.

Noise is a pulsing whir that seems to be dependant on engine speed and eminates from front of car behind dashboard.

There's been a few posts on similar topics since I stuck this one up.

I checked my receipts and Camtune regassed in Jan, so I wouldn't expect it to be low just yet unless there was a leak.

What's the probability of a new aircon rad being supplied on my OPC warranty (Low/Med/High)? If your opinion is I'm dreamin, will get trusty Camtune to sort.

possibly a buggered compressor they tend to make odd noises when they're wearing out/have a manufacturing defect
