Step-by-step explanation:
Most air conditioning manufacturers specify that refrigerant lines should be true to size and properly insulated.
Refrigerant lines carry the refrigerant between the indoor and outdoor units of an air conditioning system. It is important for the lines to be properly sized to ensure efficient operation of the system. Additionally, insulating the lines helps prevent energy loss and ensures that the refrigerant remains at the right temperature throughout the system.
