During a refrigerant system performance test the following results are recorded: outside ambient temperature of 908F, high-side gauge reading of 145 psi, and low pressure gauge reading of 14 psi. What is indicated by these results? A. Faulty refrigerant compressor B. Normal refrigerant system operation C. Low refrigerant levels D. A restriction on the high side of the refrigerant system 2. A customer complains of poor air-conditioning cooling performance. During a system performance test, the low-side gauge reading is 50 psig; the high-side gauge reading is 310 psig; and the ambient air temperature is 818F (27.228C). What is the least likely cause of the above results? A. Restricted airflow through condenser B. Refrigerant overcharge C. Refrigerant undercharge D. Overcharge of refrigerant oil
