I performed a comprehensive maintenance service on a 9-year-old Trane split heat pump system. The maintenance began with a thorough inspection of the indoor and outdoor units to identify any signs of wear or damage. I cleaned the condenser coils and evaporator coils to ensure optimal heat transfer and efficiency. The system's refrigerant levels were checked and adjusted as necessary. I also inspected and cleaned the air filters, ensuring they were free of dust and debris. The thermostat was calibrated to ensure accurate temperature control. Finally, I tested all electrical components and verified that the system was operating within manufacturer specifications.
