Found that the ahu2 had a lot of water coming out of it. I cleared the drain line. I went to run the system and the stat for this unit is missing and no one knows where it is. Also found the the outdoor unit has been shut off. This unit has not been running for some time and the water has came from a roof leak somewhere. At this time the unit is not running and they are ok with that. They will get with the home office about the communication stat for them to control from Texas.
