For those interested in mini split AC. I'll continue with where I am at this point.
The system is in and "working". The performance is not quite what I was expecting but maybe I need to adjust my expectations.
We had a hot day and here's what happened. I recorded info. on the one wall unit cooling the large family room.
Here's what happened. You see the coil exit temp. going up when I think it should have held. All the heat sources (sun, attic temp. etc.) were going down.
In any case you might like my graph.
