There are two copper lines that run between the outdoor compressor to the indoor unit (a-coil) and of those two lines one should feel very cold, with some degree of condensation present, while the other should feel warm. If both of these lines do not feel different from the ambient air temperature, it is also a sign that (a) insufficient coolant present or (b) compressor not pumping coolant.There are two copper lines that run between the outdoor compressor to the indoor unit (a-coil) and of those two lines the large one should feel very cold, with some degree of condensation present, while the small line should feel warm. If both of these lines do not feel different from the ambient air temperature, it is also a sign that (a) insufficient coolant present or (b) compressor not pumping coolant.
