Maintenance Tips

• Clean indoor air filters every 2–4 weeks to maintain airflow, efficiency, and indoor air quality in both zones.

• Keep the outdoor condenser coil free of dust, leaves, and debris to ensure optimal heat exchange and inverter performance.

• Inspect condensate drain lines and pans regularly to prevent leaks or water buildup in each zone.

• Check refrigerant lines, wiring, and unit mounting annually for safe and reliable operation.

• Use self-clean cycles periodically to reduce moisture buildup and prevent mold or odors.

• Maintain adequate clearance around indoor and outdoor units for balanced airflow and consistent temperature control.

• Schedule professional servicing once per year for inverter diagnostics, refrigerant checks, and full system optimization.
