An air conditioning companion stabilizer system for improving the operating cooling efficiency of refrigeration cycle components in air conditioning systems integrates the refrigeration cycle components with two independent, closed loops whose operation is complementary of one another. A temperature stabilizing loop functions in ambient conditions that lower cooling efficiency and is operative to absorb heat from the refrigerant exiting the condenser, thereby lowering the temperature of the refrigerant before it arrives at the expansion valve. A secondary loop, or charging loop operating in ambient conditions that enable optimal cooling efficiency facilitates the operation of the temperature stabilizing loop by priming a rechargeable heat absorbing component. Substantial net energy savings are achieved using saved heat absorbing capacity produced during a time of optimal cooling efficiency and low space cooling demand to improve performance during times of reduced cooling efficiency and high space cooling demand.
