Well said, or shall I say......well posted.
The really sad ending of this project is the fact that the original Trane split system “might” have been adequate for this project had the original installing contractor installed the right components to modify this stand system, and if he had provided a complete and comprehensive commissioning of the system.
Welcome to this forum and hopefully we’ll see more of you later in other threads. I would offer this one suggestion to you though………fill in your personal profile so we can all see who we are posting to.
Have a great day!
