Tech inspected and diagnosed HP units# 5, 6, 7, 10, 11, and 13. -HP #5 Faulty contactor not allowing power through. Replaced and system ran normally. -HP #6 System running normally. Advised installation of air filter. Pressures look good. Tech suspects unit 5 being down has forced unit 6 to carry both loads, decreasing efficiency. -HP #7 System running normally. Inspected electrical components and refrigerant pressures and found no issues. -HP #10 Not running efficiently. R22 compressor is likely losing compression potential. Pressures and amp draw look good. Management wants to replace this system. -HP #11 Compressor is shorting out. Runs for 3-5 seconds and smoke starts to appear at terminal plug-in before tripping the breaker. Capacitor read full capacitance. Management wants to replace this system. -HP #13 Condenser fan motor is seized. Receiving 230V power and capacitor is good. Overheats in 10-15 seconds before failing completely. Management wants to replace this system. Se
