By any chance does your system have a humidity setting? It *could* be that as the gunk builds up and water stands in the drain pan it is causing the humidity to increase. In response, the humidity control of the system might lowering the set temperature to try to bring the humidity back down. Just a guess.
I do have a friend who has had a terrible time with his lines this year. He flushes them and cleans them but still has trouble.
