Maintenance Tips

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

• Keep the outdoor condenser coil clear of dirt, leaves, and debris to ensure proper heat exchange and energy savings.

• Inspect drain hose and condensate flow periodically to prevent water buildup and system shutdowns.

• Check refrigerant lines, wiring connections, and mounting stability annually to avoid performance loss or electrical issues.

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

• Ensure outdoor airflow clearance around the unit and avoid blocking vents for optimal multi-zone capacity regulation.
