The High Efficiency Duct-Free AC Systems are available in 9,000, 12,000, 18,000, and 24,000 Btu/h capacities. The single zone systems feature energy-saving Inverter (variable-speed compressor) technology and can be controlled through a standard wireless remote or an optionally wired wall controller.

Whether you’re creating a quiet, comfort-controlled room, or simply want to heat or cool an area without expensive ductwork, LG’s duct-free systems set a new standard for High Efficiency Duct-Free AC systems, great looks, and comfort.

A duct-free system, also known as a “split” air conditioner system, is made up of or includes two components: an indoor unit to deliver conditioned air to the room, and an outdoor unit located outside of the house. Compact refrigerant lines run between the two units, eliminating the need for bulky ductwork. Duct-free systems are ideal for older homes that have no ductwork, room additions, or areas in homes that just never seem to be the right temperature or are never comfortable.

LG duct-free systems are available in a range of sizes and styles–including systems that can heat and cool multiple rooms with a single outdoor unit to fit almost any need. The indoor units are available in many different types to fit with the look and feel of your home while being a High-Efficiency Duct-Free AC system. Some benefits of these systems is that they are faster to install than traditional systems. With no costly ductwork, duct-free systems can be installed in places where conventional ducted systems simply can’t go. They are incredibly quiet. Indoor units operate at just 26 dB (the level of softly rustling leaves!). Custom temperature control in every space. It’s easy to precisely maintain the temperature in each room. Attractive design, where you can choose from a wide variety of elegant looks to enhance any interior decor.
