A thermal system for a vehicle includes a compressor configured to pressurize refrigerant that selectively flows through a chiller for battery coolant and an evaporator for cabin cooling. The system further includes a controller programmed to, responsive to cabin cooling demand becoming zero, change from adjusting compressor speed responsive to changes in an evaporator temperature to adjusting compressor speed responsive to changes in a chiller refrigerant pressure.
