How a Ductless HVAC System works is that the Duct-Free Split air-conditioning and heating systems consist of three basic components: an inverter-driven outdoor unit, a stylish and quiet indoor unit that delivers conditioned air to the room, and compact conduit for refrigerant lines and wiring that connects the units. This design allows for energy conservation by targeting only those areas that need cooling or heating, a cost-effective feature when only certain portions of a building are being used. Duct-Free Split systems can be used virtually anywhere LG delivers advanced climate control and operating efficiency to a wide range of residential and light commercial projects, from a stuffy bedroom to a home addition where cooler temperatures are required.


LG Ductless HVAC System split single zone systems offer many styles of indoor units to complement any décor. These one-to-one systems include an outdoor unit matched with an indoor unit, offering a complete air conditioning system for any home or light commercial space.


Multi-zone Ductless HVAC System provides outdoor units for two, three, four and up to eight separate zones. A variety of indoor units are available for any application; systems can be configured with all non-ducted, all ducted, or with both non-ducted and ducted indoor units.
