Air conditioning systems are available in all shapes and sizes. Your in-house unit operates by moving air flow across the interior evaporator coil, and heat is absorbed into the refrigerant in this coil. The refrigerant is then circulated externally, where the high temperature is depleted by way of a fan gusting through the external condenser coil. An A/C unit doesn’t create cold air flow, it gets rid of warm heat from the air. For more information please click here air conditioner maintenance davie
