I recently performed a comprehensive maintenance service on an 11-year-old Carrier split heat pump system. The maintenance began with a thorough inspection of the unit's components, including the compressor, condenser, and evaporator coils. I cleaned the coils to ensure optimal heat transfer and checked for any signs of wear or damage. Next, I inspected and cleaned the air filters, replacing them if necessary to improve indoor air quality. I also checked the refrigerant levels and ensured they were within the manufacturer's specifications. Additionally, I lubricated the motor and checked all electrical connections for tightness and integrity. Finally, I tested the thermostat and controls to ensure they were functioning correctly. This maintenance will help extend the life of the system and improve its efficiency.
