Keep the systems you have and add cool and condenser to each.

Ok, I am going to try and combine groups so as to condense the material. 

Should this condensation line be moved?

There are also courses in multi-family units and construction, which is appealing to me.All that considered, can I learn this in a condensed format outside of this setting?

Also be sure to check that the underside of the roof is insulated with some sort of condensation barrier.

Did most of the work myself.A vapor barrier usually protects against condensation which is important. 

There isn’t a known leak however there are areas of condensation accumulation which then thaws at times and saturates drywall.

Their work is phenomenal and decades of research condensed into each respective book. 

Three AC techs later (all confirmed the old unit worked fine) and after much research on my own about the thermostat her engineer brother had installed, figured out that it cut itself off (condenser but not the fan) after running awhile bc engineer brother didn't know how to wire new fangled thermostats and the onboard battery when discharged would issue an emergency cutoff call to the condenser.

Your ac condenser and evaporator coil were not designed for different mixtures of crappy Chinese refrigerant and the two different chemicals will react. as all chemical compounds do when you mix them.
