On split-system installations, why is the liquid line never insulated?

Typically the LL is not covered to allow additional subcooling. On a few applications you may want to cover the LL. Ductless split systems sometimes have an orifice in the ACCU and the line could sweat.

Thank you. But how could subcooling happen if the uninsulated LL is up on a roof exposed to the sun?

Time and money is the reason they are not insulated however:
Liquid lines that will be exposed to direct sunlight should be insulated.
