"The tech was professional and arrived on time. The general routine cleaning went fine. However, the troubleshooting did not resolve the issue. He did notice the unit leaning a bit and straightened it out, but a couple of months later during another hot spell the unit was leaking again. I called them and they sent the field manager who cut and replaced a very crooked condensate line and it appeared all was resolved. Fast forward 10 months of rare usage: after 3 days in a hot spell - the leak reappeared. I shut off the a/c and waited for a good 5 months before calling a different plumber who blasted out the main condensate and the secondary line, and tested it by running a gallon of water through the line. I don't believe the line was sufficiently cleared if at all, the first two visits with Carini. This seems like a pretty routine issue with condensate lines so I'm disappointed that it would have been either overlooked or insufficiently cleared out.
