LG LMU300HHV 30,000 BTU Configurable Quad-Zone Multi F Mini-Split Air Conditioner Heat Pump - Energy Star
LG's NEW Multi-F Systems now include LGRED° Heat Technology featuring low temperature heating down to -13°F!
LG's new line of energy efficient multi-zone systems is here. The entire line features LGRED° Heat Technology, making each unit a perfect solution for cold weather climates. The LG LMU300HHV can be operated in the heating mode when temperatures get down as low as -13°F. When it gets down to 5°F it will perform at 100% heating capacity. The system will also provide low ambient cooling to 14°F. Add a Low Ambient Kit (sold separately) for cooling operation down to -4°F. The new LGRED° Heat Technology Systems also include a factory installed Base Pan Heater to ensure better heat performance in colder weather.
The LG LMU300HHV is a 30,000 BTU, configurable, multi-zone mini split air conditioning and heating system. Flexibility is part of the name with LG's Flex Multi-F Quad Zone Multi-Split air conditioner. The LMU300HHV gives you the flexibility of choosing two, three or four indoor units. Mix and match units to fit your room size and decor. This four-port system offers a combined BTU connectivity rating of up to 40,000 BTUs. With a focus on energy efficiency, this mini split system offers a high SEER rating and is Energy Star Qualified when used with non-ducted units only.
The improved heating range on this system allows for operation in the heat mode when outdoor temperatures are as low as -13°F. With heating possible when it is that cold, this unit is a feasible option as a primary heat source for much of the country. And, if you need to keep an area cool even when it is cold outside, this system will operate in the cooling mode with temperatures as low as 14°F.
Each unit comes with its own remote or thermostat giving you the utmost in comfort flexibility. Each space can be adjusted individually or completely off. Another advantage of adding a mini-split system like the LMU300HHV is the ease of installation. No ductwork is needed and, while each indoor unit requires a line set and wire (sold separately), only a small 3” hole is required to connect each indoor unit to the outdoor unit.
In addition to being an energy efficient way to heat and cool your home, the LMU300HHV outdoor unit offers many other standard features including a variable speed inverter compressor, defrost/deicing capabilities, three minute restart delay, and a self diagnosis system. The LG Multi-F compressor uses a soft start in an effort to reduce power surges on the electrical system. The outdoor unit will operate in the cooling mode when the outside temperature is as low as 14°F. In the heating mode perform with temperatures ranging from -13°F to 75°F. To top it all off, it uses environmentally friendly R-410A refrigerant and is pre-charged for up to 98 feet of line.
LG offers ultimate flexibility and configurability in your selection of indoor unit. All indoor units offer a variety of fan speed options and auto restart operation. You can use the dropdown boxes above to customize your system. Need help deciding? Contact us for expert advice.

Art Cool Gallery (LMAN097HVP, LMAN127HVP) - An Art Cool Gallery unit can be a beautiful, non-obtrusive way to get conditioned air into any room of your choice. A 2’ x 2’ frame allows you to display a personal piece of artwork (or the included piece). The air is dispersed quietly and efficiently from the edges and bottom of the frame into your room.

The line set and wire (required, sold separately) connect to the compressor outside through this opening. A wireless remote is included for easy control. Available in 9,000 or 12,000 BTUs.
Ceiling Concealed Low Static Unit (LDN097HV4, LDN127HV4, LMDN186HV)- Low Static Concealed Ceiling units are installed in a ceiling and hidden from view. They require ducting as well as registers. The registers allow the conditioned air to come down into the space. Depending on the size and shape of your space, a concealed unit can be ducted for multiple rooms or one single room. As an example, an 18000 BTU unit will provide comfort control up to about 825 sq. ft. A drain pump is included with this unit as well as wired thermostat for control. Available in 9,000, 12,000, and 18,000 BTUs.
Ceiling Concealed High Static Unit (LMHN240HV) - High Static Concealed Ceiling units are installed in a ceiling and hidden from view. They require ducting as well as registers to allow the conditioned air to come into the space. Depending on the space you are trying to condition, a high static unit allows for longer duct runs from the unit itself. This way, you can install the unit and duct off into several individual areas, wherever the air is needed. This may be one large space or multiple rooms. The 24,000 BTU unit will provide comfort control up to about 1100 sq. ft. A drain pump is included with this unit as well as wired thermostat for control.
Ceiling Cassette Unit (LMCN077HV, LCN097HV4, LCN127HV4, LMCN185HV) - A ceiling cassette installs into the ceiling and offers 4-way airflow into your space. A grille is required on a ceiling unit (standard white grille included) and air is dispersed from all 4 sides of the grille. A ceiling cassette can be installed in the center of a room, allowing airflow all around. Alternatively, it can be installed along the edge of a room, closing off 1 or more "vents" for customized air flow. A drain pump is included with this unit as well as a wireless remote control. Available in 7,000, 9,000, 12,000, and 18,000 BTUs.
Vertical Air Handler Unit (VAHU) (LMVN240HV, LVN180HV4, LVN240HV4) - LG currently offers two types of vertical air handlers. There is a 2-way air handler (LMVN240HV) that can be used for upflow and downflow installations only. Also available are 4-way, multi-position air handlers (LVN180HV4 and LVN240HV4). A multi-position air handler can be installed as an upflow, downflow, horizontal left or horizontal right installation. This allows for attic or basement installations. A vertical air handler may be used as a way of replacing a conventional air handler currently being used as part of a central system. Another possibility may be that you are looking to zone your dwelling with a mini split system regardless of whether you are using existing ductwork or adding new. The 18,000 BTU multi-position unit will add comfort control to a space that is about 800 sq. ft. Either of the 24,000 BTU units can be ducted units into several rooms totaling about 1100 sq ft. All units will heat and cool your space both appropriately and efficiently. Regardless of the number of spaces you are cooling/heating, an included wall mounted thermostat will control that zone.
