Based on the info from the Entegra site it is the quality of the copper tubing. There tend to be small impurities in the tubing that weaken the tube's wall, so after many heat cycles the tube develops a pinhole leak. Wieland-Kessler supposedly had found the problem and corrected it but it will take a couple years for all the bad A/C units to be filtered out of the system.
