Air conditioning systems come in just about all styles and sizes. An indoor unit works by moving air flow within the indoor evaporator coil, and heat is absorbed inside the refrigerant within this coil. The refrigerant is then distributed externally, where the high temperature is exhausted with a fan blasting across the external condenser coil. An air conditioner does not create cold air flow, it takes away heat in the air. For more information please click here air conditioning service hialeah
