LG produces two types of air conditioning systems, duct-free units and Multi-V variable refrigerant flow systems. Duct-free LG air conditioning systems are available in two variants, single zone air conditioning units and multi-zone heat pump systems that can cover up to eight separate zones.
LG's VRF products are designed for either indoor or outdoor use. The company's VRF air source units use a heat exchange system that uses air from the outside and transitions it inside. LG's VRD units also include water source systems that use water as a heat exchanger and are generally fitted with compressors to operate quietly.
