I think he means raising capacitance at the motors.It can be done on the air conditioners up to ten % I've also seen hard start kits installed to reduce the flicker effect.I would however stay awaything other than hermetic compressors.A refrigeration wholesaler will have a $80 or so kit sized for the A/C units.But there is still no guarantee.Also make sure the a/c units are staged properly with a "staging thermostat" or there will be power sags.Cycle the units one at a time and see if there a difference.
