Maintenance Tips

• Check & replace filters: Clean or replace the air filter regularly (every 1–3 months or more often in dusty environments) to maintain airflow and indoor air quality.

• Keep coils clean: Periodically inspect and gently clean the evaporator coil and blower area of dust and debris to preserve efficiency and airflow.

• Inspect drainage: Ensure the drain line and pan are clear to prevent water buildup and potential overflow issues; clean as needed during seasonal checks.

• Monitor airflow: Check that supply and return ductwork are free of obstructions and that dampers are set correctly for balanced airflow.

• Control check: Verify thermostat and Wi‑Fi control settings function properly; update firmware if available for optimized performance.

• Inspect wiring & connections: Periodically ensure electrical connections are secure and check for signs of wear or corrosion.

• Annual HVAC service: Have a qualified HVAC technician inspect refrigerant lines, fan motor, belts, and overall system operation at least once per year.

• Ventilation & clearance: Keep the area around the handler clear, and maintain proper ventilation to prevent restricted airflow or overheating.
