A ductless split system is similar to a central air system; however, this system is unique. It is a split (2part) design. It comes with an indoor air handler and the noisy condenser which is installed outside. You no longer need expensive and invasive ductwork. It only requires a 3" opening in the wall or ceiling, and installation is easy. Simply mount the indoor and outdoor units, connect the refrigerant lines, and make a few electrical connections. Most installations can be done in a day. LG supports and recommends that a qualified air conditioning contractor properly size and install LG DuctFree (ductless) air conditioners for optimal performance and long life.
