Purging oil from refrigerant lines
I am working on a carrier heat pump setup. I had changed out the compressor and found a good amount of oil had collected in the low point of the evap coil. I have tried to flush it out with nitrogen but it just gurgles in the lines. Are there any better techniques for flushing this oil out?
Unit model is a 50TJQ006---501GA
