A water-cooling system for an air conditioning unit is presented. The water-cooling system has a solar panel, a water storage unit and a mist distribution system. The solar panel converts solar energy to electrical energy. The water storage unit has a submersible pump that has at least one intake port and an output hose. The water storage unit has a liquid reservoir may be supplied by a condensation drain of the air conditioning unit. The water storage unit may also have an overflow switch such that the unit can be turned off to prevent overflow into a house for example, or the liquid reservoir from drying up and burning out the submersible pump. The liquid taken in by the submersible pump is delivered to the mist distribution system which supplies the liquid to a plurality of distribution points. When the liquid is received at the distribution points, the liquid is sprayed in a misting pattern onto the air conditioning unit thus improving the performance of the air conditioning unit.
