[DML] AC compressor whining

["ryanpwright" <dmcnews_list@xxxxxxxxxxxxxx>]

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.

Thank you,

-Ryan
