Flex Multi-Split systems operate one, two, three or four interior units that are mounted in separate rooms. Each indoor unit comes with its own remote control, allowing the customer to set the temperature individually in different rooms. These units are connected to a single outdoor unit. The indoor units are available in a variety of styles, including Standard Wall Mounted, Art Cool Wall Mounted with customizable mirror finish, Ceiling Cassette, and Ceiling Concealed Duct models. 

LG LMN126HVT Wall Mounted Mini Split Indoor Unit uses an inverter, which uses a variable speed compressor that is quieter to operate and uses less energy than conventional air conditioners. When the selected temperature is reached, the inverter compressor operates at low speed to maintain that comfort level. LG inverter models have efficiency ratings of 16.0 - 19.7 SEER, making them among the most energy efficient in the industry. Plus, with capacities ranging from 9,000 - 48,000 BTUs, its easy to find a unit to match any size room. Finally, when the weather turns cold, its reassuring to know that the LG LMN126HVT Wall Mounted Mini Split Indoor Unit offers more heating power than conventional mini split heat pump systems. Whats more, LG inverter models are as stylish as they are efficient. This product comes with one of the best warranties in the industry! The warranty provided will be 2 years on the parts.


  • Multi Power System. Energy-saving twin compressors: one provides power at 60% capacity until the system reaches a desired temperature. Then the smaller compressor takes over to provide sustained operation at 40% capacity.
  • R-410A Refrigerant. Environmentally friendly refrigerant utilized in the majority of LG systems.
  • Patented Plasma Air Purifying System. The 4-stage system features a large, permanent filter and an electronic air purifier that captures microscopic contaminants like dust, mite, pollen and pet fur.
  • Self-Cleaning Indoor Coil. Drives dirt and moisture from coil surface leaving it clean and fresh smelling (Art Cool Models).
  • Dehumidifying Mode. LG Indoor unit accurately senses room temperature and controls humidity by shutting down the compressor before a room is over-cooled.
  • Chaos Swing. Electronically controlled louvers and fan speeds create a more natural, random flow of air, reducing temperature stratification.
  • Art Cool Three-way Cooling. Air flows out of the unit from three directions, creating more natural circulation.
  • Jet Cool. Operates at high speed for up to 30 minutes to quickly cool a room down to 64 F.
  • Swirl Wind. Four-way controlled louvers and fan speeds create a stronger, wider air flow and reduce temperature stratification.
  • Auto Operation. Provides three levels of comfort from which to choose. Temperature and fan speed will set automatically.
  • Manual Power Switch. Easily accessed button allows for continued operation if the remote control is misplaced.
  • Defrost Control. Shuts down the indoor fan to prevent cold air from being blown into the house. Removes frost from outdoor coil when the outdoor temperature is low.
  • Temperature Display. Shows room temperature of interior unit.
  • Auto Sleep Mode. Automatically increases the temperature setting 2 F twice (after 1/2 hour and one hour). The interior unit shuts off when the timer setting is reached.
  • Auto Restart. Automatically restarts a unit to programmed setting when the electricity comes on after a power failure.
