Bethany Brown · Accepted Answer

Final Answer : D, Explanation :  Technician A is incorrect because suction lines in an A/C system are usually cool to the touch as they carry low-pressure, cooled refrigerant back to the compressor. Technician B is also incorrect because discharge lines are usually warm or hot to the touch and of smaller diameter than suction hoses, as they carry high-pressure, heated refrigerant away from the compressor.
