Has anybody experienced evaporator leaks in Trane® GEVA or GEHA water source heat pumps. We have installed a number of these in high end residential applications with earth coupled condensers. We have had 50% failure rates per address and Trane® contends that we are the only contractor in the nation with this failure rate. We have experienced replacement coils leaking on start-up and one with a u-bend missing. They still contend that we are the only contractor with this problem. We service a residence with 9 units installed by a rival contractor and have experienced the same failure rate.
Please comment on this as we are havig difficulty believine that we are alone in this.
