Abstract: Improved air-conditioning system having an assembly of constituent elements comprising a water solenoid box with a control switch, the solenoid box being connected to the electrical system of the condenser unit; water filter means to purify the water flowing into the solenoid box; a main water supply line, extending from the solenoid box to the condenser housing unit and affixed, circumferentially around the exterior periphery of the housing unit; and a plurality of distribution tubes (micro-tubing) each extending downwardly from the main water supply line and terminating in a micro spray cap, the spray cap being adjustable to control spray pattern and flow rate. Water, dispersed from each of the micro spray caps positioned around the periphery of the condenser unit, lowers the temperature and pressure of the compressor and lowers the RLA of the compressor.
