Air conditioning noise

Hello,

I have a problem, I had my air conditioner rebuilt 1 year ago and all the seals were replaced with factory ones because of gas leaks. Since then the sealing is 100% but sometimes the air conditioner makes noise. You can't hear anything in the engine compartment, only indoors, and the sound is sometimes nonexistent, sometimes louder, sometimes quieter, and always varies with rpm. I attach a video, this is the sound mine makes. No fault code, pressure checked, and the compressor is working fine, blows cold at 5°C. Another important thing is that if I turn it to the coldest setting, the sound doesn't necessarily come out, very rarely, but if I turn it to the warmest setting, it comes out very quickly (about 200m)
