Keep one DX Unisplit unit covered for a longer service window. This 2-year cool upgrade is intended for a single ceiling or wall mount DX Unisplit unit, giving operations teams added continuity around cooling support and maintenance planning. For facilities that depend on precise environmental control, service coverage matters as much as the equipment itself. Extending the cooling upgrade period helps reduce uncertainty around support timing and gives procurement a cleaner way to align protection with budget cycles, refresh plans, and uptime requirements. It is a practical choice when the cost of a cooling interruption is far greater than the cost of planned coverage. This APC upgrade is designed for organizations that want to preserve service continuity on a specific DX Unisplit installation without overbuying coverage they do not need. It is a focused, asset-level protection option for teams managing critical spaces, controlled environments, or distributed sites where cooling availability is part of the operating baseline.
