I must have not made myself clear. My system was still producing cool air (barely)when I took it in. When I had the system serviced 13 months ago, the compressor would not engage and the system was only 1 lb down. This time, the compressor was engaged and the A/C guy said that he had to pump 2.5 lbs of R12 into the system (meaning there was .40 lb in the system before he pumped it up). I think he stuck it to me since I don't believe the compressor would still be engaging with only .40 lb of R12 in the system before I took it in.
