Ac units are available in all styles and sizes. An indoor system operates by transferring oxygen through the interior evaporator coil, and heat is absorbed inside the refrigerant in this coil. This refrigerant is then circulated to the outside, where the high temperature is depleted with a fan blowing across the external condenser coil. An A/C unit doesn’t create cooler air, it removes heat from the air. For more information please click here Turners Service Co
