Looks like my stash room AC is fucked then.

Small AC unit in my room has not been working properly for a few months now. Just after Christmas my mate came over and topped it up with refrigerant and it worked again for a couple weeks but then I got the same fault code low on gas.
We put some tracer in it tonight and found the compressor has rusted out under the bottom. This is totalled hope to get a new unit in in the next couple weeks plus side is I have a 6.5kw Toshiba I am going to replace it with. The old one my mate reckons the compressor has rusted right through it’s a real shame as the indoor unit is like brand new absolutely mint but the outdoor unit is completely fucked
