A vehicle heating, ventilating, and air conditioning (HVAC) system having a variable compressor can reduce a load applied to a vehicle powertrain during certain conditions. Systems and methods can determine if a power state of an HVAC system is activated, and whether an engine water temperature meets a forced HVAC recirculation intake threshold. Responsive to determining that the engine water temperature meets the forced HVAC recirculation intake threshold, a recirculation mode air source can be selected for the HVAC system. Responsive to the recirculation mode air source being selected, determining if at least one measured vehicle condition meets predetermined criteria. Responsive to determining that the at least one measured vehicle condition meets the predetermined criteria, the variable compressor can be operated according to a reduced duty map.
