They tried to sell me a new compressor because the existing one was leaking the gas. They wanted $1200. I declined since I found the priciest replacement compressor cost only $400. It is cheaper to simply replace the gas each summer.
leak at the compressor required replacement of the compressor
AC stopped blowing cold air. Two separate technicians diagnosed the repair and recommended a new A/C Compressor, however both determined that the AC Drier was not damaged and did not require replacement (saving me $250-300. Repair costs quoted by both were approx $950. The repair actually costs $979.
