Thanks, Bubba. I agree with your opinion that a good vacuum can greatly increase compressor life. I have worked with commercial R22 chillers in the 60's and have worked with automotive R12/R134 systems quite a bit. I have my automotive papers to handle the refrigerants and equipment available if needed. I do not trust my welding and brazing ability enough to guarantee against leakage and with a heart problem would have physical problems to do the labor part. Just for the info of yourself and others that have replied, I greatly appreciate your comments. 10 years ago, I would have tackled this in a second but, because of my physical limitations, I do not desire to do the compressor or unit replacement myself unless I am unable to come up with a competent tech. I am just trying to be sure I am not looking at a $10 solution to a 2 bit problem. If I need the $10 solution, I will simply take take my medicine.
