1. A climate system for conditioning a compartment of a vehicle, comprising:
one or more sensors configured to obtain measurements corresponding to a vehicle;
a first compressor driven by an engine of the vehicle, the first compressor configured to compress a refrigerant;
a second compressor driven by an electric motor, the second compressor configured to compress the refrigerant; and
a controller electrically coupled to the first compressor, the second compressor, and the one or more sensors, the controller configured to:
receive a user defined temperature threshold for a compartment of the vehicle;
in accordance with a determination that the measurements obtained via the one or more sensors indicate that a temperature within the compartment of the vehicle exceeds the user defined temperature threshold, determine a thermal load of the compartment, wherein the thermal load of the compartment is based, at least partially, on a difference between the user defined temperature threshold and the temperature within the compartment of the vehicle, and
operate the climate system in a predetermined mode based on the thermal load exceeding one or more predetermined thermal load thresholds, wherein:
the predetermined mode is initiated in accordance with a determination that the thermal load exceeds a second predetermined thermal load threshold less than a first predetermined thermal load threshold, and
operating the climate system in the predetermined mode includes activating the first compressor to cool the compartment of the vehicle.
