AC cooling upstairs but not downstairs
So here is my dilemma, and I know its usually the other way around. We have a two story house, 1 unit but 2 thermostats. The upstairs is cooling nicely, but there is no cold air blowing downstairs, at all. I also noticed that there is a drain on the 2nd story that has been pouring out water. Any suggestions as to what might be wrong, and where to look/how to fix it would be greatly appreciated.
