Anybody else having trouble with climatemaster refrigerant leaks? No difference between genesis or tranquility units, all from about the 3 to 7 year old mark. In the past year I have had 4 black epoxy evaporators leak, 1 coax, and 2 from factory brazes. Got a few others that needed small charge during spring maintenance, yet to find the exact leaks. Maybe I'm thinking too far into it and this is typical. I geuss I have to consider the amount of geos we service that dont leak. : /
