LG Ductless Air Conditioning Systems offer convenient solutions that are cost-effective, quiet, and attractive. These innovative systems are "split" into two efficient units. The wall-mounted interior unit is slim, lightweight, and aesthetically pleasing. Each interior unit has a remote to control unit settings and temperature. Duct-free systems are ideal for home or office additions, to replace unsightly window units, and for renovations or retro-fits where it's important to preserve the building's original appearance.
