Hello All,Reaching out to anyone who has experienced compressor issues with the stock AC system?We recently picked up our TZE here in Ontario and took it to Borrmann's Garage in Bluevale for some mechanical work and road safety certification.  The initial repair for the cab AC was a few O-rings, evacuation and recharge.   In the last few weeks of test drives, the compressor began to get noisy and we opted to have a rebuilt compressor put in.  The first one installed would not build enough pressure, the second one was seized out of the box.  A third one is going in tomorrow, and if that fails, we will address it in the Spring with an alternate rebuild or a updated conversion.Any thoughts on the rebuilds or an updated system?Thank you,Eric

The answer is to go with a Sanden compressor and switch out of R12 to HC12 refrigerant. Perhaps Borman's Garage already made that conversion.
