I recently completed a comprehensive maintenance service for an existing Alaskan AC customer's heat pump system. This involved a thorough inspection of the entire unit, including the compressor, condenser, and evaporator coils. I checked and cleaned the air filters, ensuring optimal airflow. Additionally, I calibrated the thermostat and tested the system's electrical components for proper functionality. Lubrication of moving parts was performed to ensure smooth operation, and I also inspected and cleaned the drainage system to prevent clogs. Finally, I provided the customer with a detailed report on the system's condition and recommended any necessary adjustments or future maintenance schedules.
