My AC compressor is whining. Actually sounds like a screaching noise... - Doesn't matter whether the AC is on or off - Noise varies in pitch with RPM - Noise also comes and goes in same RPM band every time. I can hear it from 1900-2200, 2800-3000, etc. - Spraying WD40 between the pulley and the compressor stops the noise. I have to repeat this every 1 - 2 weeks. Question: Do I have to replace the compressor, or are there bearings or something else in there that can be repacked/replaced/etc? If I have to replace the compressor, I might be wise to convert to R-134A. What is involved in this procedure? I have a local A/C shop that I trust enough to do some of this work.
