TMRCIN, I see your message!
These are all really good thoughts, I am going to pass them on to the dealer. It was the owner himself who installed my system, and he is coming out monday morning with a trane rep.
I'm thinking of printing out this entire thread and showing it to him. You all have a lot of good suggestions, and I greatly appreciate them.
By the way, yesterday my son had a few friends over, and it was a warm, humid day, and we were actually getting too hot. About 4:00pm I set the air conditioner to come on to cool at 72 degrees. I kept it to air condition all night till about 12:00 noon today. It wasn't stale at all, seemed fresh enough, and only a little drier than I'm used to, which makes sense, it's a new system and SHOULD, as you all have said, remove moisture. I definitely felt better than the heater mode.
About an hour ago, since the air doesn't come on that much, and it seemed to be too humid and a little chilly again, I turned the heat on. I can alrady tell its stale and dry. In other words, there's a lot of fluctuation in comfort, is this normal?
