(Thermal Growth Valve), strainers, filters, dryers or any other connections. The refrigerant lines that run from the evaporator coil to the outside unit are checked in the exact same fashion. Be sure to check the modest capillary tubes that are protected with a black piece of refrigerant line set insulation.
