Checked over the system. On arrival the upstairs zone was calling for cooling but the furnace heat was on. After resetting the system the heating and cooling for that zone was working fine. Maybe an issue with the ignition board or some board. The customer also stated that the downstairs zone was blowering air even when it's not calling for heat or cooling. The dampers are weak and allowing air to past them. This zoning system is powered close spring open. I'd recommend replacing the zone system and go from there. The ignition board may need to be replaced but not sure yet as the system is operating at this time.
