Hello everybody,

One month ago, I have installed an AC unit in my apartment by a professional. I have a condensation evacuation tube for the inside unit, but there is still water condensation on the copper tube connection on the outside compressor : check photos.

Outside where the condensation is, the copper tube changed the color to black... I don't know if this is normal.

For now, I don't see any performance problem but I am concerned about the durability of the installation.

Thanks.
