My understanding is they are either quick connects or threaded fittings of some sort with valve in the fittings. Line sets are pre filled, no evacuationg needed. Bad thing would be you need to find a way to route any excess line as you can't cut them. If you do cut them you would then need to evacuate the system (or at least the portions you exposed to atmosphere) to get best performance results anyway.I have heard of these. I am unclear how the line set is connected. There is perhaps some misunderstanding about "no refrigerant needed" because they all come with refrigerant that will work up to a certain line set length. I guess you could have a line set already evacuated/filled as needed, but how do you connect it to the compressor?
You don't need to know how to tell if unit is charged properly as long as you don't let contents leak out during installation. Is sort of not much different than a self contained unit that is already charged when you purchase it. Once leakage has occurred - you need to know how to properly recharge, and maybe even know how to fix whatever caused the leakage.
