if got oil how to ensure the oil can return back to the compressor so the compressor won't wear out due to lack of lubrication?

so far i never hear people talk about copper pipe requiring slope on the outlet like drain pipes do.

hi, sorry i'm noob so i don't know what psi they are running at.

so doesn't matter if my pipe is going upwards or downwards the pressure will be sufficient to circulate the oil around without clogging the pipes? will this cause more load to the compressor and reduce it's durability?

i know water pipes have enough pressure to flow around pipe but not sure how gas pushes oil around with sufficient pressure even though gas is also considered as fluid.

hmm it's possible if you manually adjusted the swing it becomes misaligned with the gear causing plastic hitting plastic sound when put on swinging mode but normally don't have to wait 4 hours to hear the sound.

usually i hear this when i turn on the aircon or turn off.

The oil inside the copper pipe called refrigerant, not working as lubricant but for cooling purposed.
Compressor will compress the gas become liquid, that is how the presure come from..

Answer to you question: Yes, the copper pipe can going whichever direction since it was pressure pipe. as long as don't too far away.

o i though refrigerant is mainly to carry the colder temperature to the indoor unit and recycle, though oil is another separate liquid mixed inside the pipe.
