Maintenance Tips

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

• Keep the outdoor condenser unit clear of dust, leaves, and debris for optimal heat exchange and inverter performance.

• Check condensate drain lines regularly to prevent water buildup or leaks.

• Inspect refrigerant line insulation and electrical connections annually to ensure safe and reliable operation.

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

• Maintain adequate clearance around indoor and outdoor units for consistent airflow and system performance.

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