Abstract: An air conditioner condensing coil cooling system comprising an evaporating unit inside a house having an evaporating coil for evaporating a refrigerant liquid and a condensing unit remote from the evaporating unit located outside the house having a condensing coil for cooling refrigerant gas into liquid refrigerant. A condensate collector included in the evaporating unit for collecting condensate that condenses on the evaporating coil. A drain line extending from the condensate collector out of the house and connecting to a pump outside the house for drawing the condensate through the drain line. A manifold positioned adjacent the condensing coil connected to the pump for receiving condensate from the condensate collector through the drain line. The pump forcing condensate through spray holes in the manifold to provide a pressurized spray of condensate being applied onto the condensing coil.
