LG is known as a leader in ductless air conditioner mini-split systems. A ductless split system is similar to a central air system; however, it is a split (2-part) design that consists of an indoor air handler (as seen on this page) and the noisy condenser (sold separately) which is installed outside. LG supports and recommends that a qualified air conditioning contractor properly size and install LG Duct-Free (ductless) air conditioners for optimal performance and long life.
