does an air condition loose a lot of oil during refrigerant removal?
Hello!
I am in interested in listening your opinions about that subject.
I have a split a/c which its refrigerant (R407c) was gone out to the thin air.
probably the former technician let it out on the air.
the question is if that a/c has lost a vast amount of oil ,(during the exertion of refrigerant through hoses), so as to cause problem to compressor after re-filling it with new refrigerant?
some techs in Greece believe that adding oil to a split a/c can cause capillary blockage.
they assume that if a small amount of oil is lost, try not to add any oil otherwise you will cause troubles.the compressor has enough oil in its carter and only a small amount of oil circulate through the split a/c cycle.
what is your opinion?
