I conducted a thorough evaluation of the air conditioning system during the maintenance visit. I started by asking the customer about any specific concerns they had regarding the system's performance. I then assessed the condition of the furnace filter and evaporator coil, recorded the blower amp draw, and inspected the cleanliness of the condenser coil outside. I also checked the electrical components of the condenser for any signs of burnt or loose wires and verified the microfarad readings on the capacitor. Finally, I confirmed that the refrigerant pressures were within the correct range to ensure optimal system performance.
