I'm out of ideas for leak detection now...
I've cured one medium leak on the system by replacing the condenser (also comes with new drier) and a lower pipe.
It was held on vac test for an hour and showed no drop in pressure at all. 3 weeks later the system has just dropped enough pressure to stop the compressor coming on.
Obviously this is a very small leak, and I can't see any dye anywhere around the system with a UV light.
Is there any other way to find a very slow leak apart from leak dye? Wondered if there was some sort of 'sniff' test similar to an emissions probe?
Also, has anyone tried the DIY leak sealer in a can? Or is there a professional type at AC specialists? I'm not a fan of sealers as they can just block pipes but as it's such a small leak I'm not sure how else I'll find it.
