Great write up man! The only thing I will mention is that you want your TXV bulb directly against your suction line
(no insulators) the TXV (expansion valve) needs to read the true temp of that suction line in order to accurately meter refrigerant into the evaporator coil. The heat shrink will slightly skewer the effectiveness and efficiency of your system. I wouldn’t worry about it now but for anyone in the future. I think if you wrap it tight enough you shouldn’t have a concern about a rub through.
