Air conditioning units are available in just about all shapes and sizes. A person's household system operates by transporting oxygen through the interior evaporator coil, and heat is taken inside the refrigerant within this coil. The refrigerant is then moved to the outside, where the heat is drained with a fan blowing through the outside condenser coil. An air conditioner does not create cold air flow, it eradicates heat in the air. For more information please click here air conditioner maintenance hollywood
