Technician cannot resolve an HVAC system with high suction and high head pressure, 80% humidity at vent, despite replacing TXV, dryer, and adding refrigerant.

Existing diagnostic tools (psychrometer, gauges) indicate multiple conflicting symptoms (high pressure, high humidity) but fail to pinpoint root cause or guide next steps.
