What is a central air-conditioning unit?


Central air conditioner units are energy moving or converted machines that are designed to cool or heat the entire house. It does not create heat or cool. It just removes heat from one area, where it is undesirable, to an area where it is less significant or makes no difference.


Central air conditions has a centralize duct system. The duct system (air distribution system) has an air handler, air supply system, air return duct and the grilles and register that circulates warm air from a furnace or cooled air from central air conditioning units to our room. It returns that air back to the system and starts again.


It uses Ac refrigerant (you may know it as Freon) as a substance to absorb the heat from indoor evaporator coils and rejects that heat to outdoor condenser coils or vice versa.


Central air conditioning units used a blown, which is mounted indoor to a furnace to circular that cold air to the entire house through air distribution system (duct). It uses the same duct system for heating and cooling.
