Embodiments of the present disclosure relate to a heating, ventilation, and/or air conditioning (HVAC) system that includes a first control configured to control a supply of power to a plurality of compressors based on an air flow through the HVAC system exceeding a first threshold, and a second control configured to supply power to a subset of compressors of the plurality of compressors based on the air flow through the HVAC system exceeding a second threshold while being below the first threshold.

Low load mode of HVAC system

A heating, ventilation, and air conditioning system includes an air moving device configured to move air through the HVAC system, a first variable frequency drive (VFD) configured to drive the air moving device, and a second VFD configured to drive the air moving device, wherein the first VFD and the second VFD are configured receive control instructions and to selectively operate based on the control instructions.
