Maintenance Tips

• Replace Air Filters Every 1–3 Months: Keeps airflow optimal, protects the blower motor, and ensures efficient heating and cooling.

• Keep Surrounding Area Clear: Remove dust, debris, or obstructions around the unit to maintain proper airflow and service access.

• Inspect Condensate Drain: Ensure the drain line is clear to prevent water buildup and potential system damage.

• Check Electrical Connections: Periodically inspect wiring and connections for wear, corrosion, or loose fittings.

• Monitor Built-In Heater Operation: Verify the 5kW heater functions properly during heating cycles for safe and efficient performance.

• Schedule Annual Professional Maintenance: Technicians should inspect the blower motor, coils, refrigerant lines, and overall air handler operation yearly.

• Listen for Unusual Signs: Any unusual noises, odors, or airflow changes should be addressed promptly to prevent larger issues.
