Maintenance Tips

• Clean indoor air filters every 2–4 weeks to maintain airflow, cooling/heating efficiency, and indoor air quality.

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

• Inspect condensate drain lines and dual-drain ports periodically to prevent leaks and water buildup.

• Check refrigerant line insulation and electrical connections annually to avoid performance loss or safety issues.

• Use the self-clean cycle regularly to reduce moisture buildup and prevent mold or odors.

• Maintain sufficient clearance around indoor and outdoor units for proper airflow and consistent room comfort.

• Schedule annual professional service for inverter diagnostics, refrigerant pressure checks, and system optimization.
