Upon arrival spoke with customer. He wanted speed adjusted for the indoor unit. Black wire is high, it was blue when I got here witch is med high. Customer approved doing repairs. Switched wires and checked over system. Explained gas line should not be flex coming into the unit. Coil is clean, no hits on leaks. Indoor is working good. Went outside, wires are tight. Contacter and capacitor working properly. Fan and compressor check within specs. Refrigerant levels are within specs. System is working at this time but could fail at any time due to age.
