[DML] Re: Air Conditioning / Clicking Noise

["DMC Joe" <DMCJOE@xxxx>]

Kayo,

I don't have any specs' but I do have two owners in my data base who have
done the conversion. One is partially satisfied and comments that the AC is
not as cold as it was with R-12. The other owner is completely disgusted
and said he is wished a friend of his never convinced him to make the
change. Obviously we agree with you and strongly discourage any one from
making the change.
