LG LMU18CHV 18,000 BTU Class Configurable Dual-Zone Multi F Mini-Split Air Conditioner Heat Pump - Energy Star
Get year-round comfort in all areas of your home!
The LG LMU18CHV is an 18,000 BTU class, configurable dual-zone mini split air conditioning and heating system. LG's Flex Multi-Split Dual Zone air conditioner system gives you the opportunity to install two indoor units in separate areas of your home. The LMU18CHV offers a combined connectivity BTU rating of up to 24,000 and can be configured to include a combination of wall mounted and ceiling units. When connected with non-ducted units only, the system maintains its Energy Star Qualification.
The Multi-F / Flex Systems are not only cost and energy efficient, they are also able to offer comfort year round with enhanced cooling and heating ranges. This system can be used as a primary heat source in most of the country. It is capable of heating when outdoor temperatures are as cold as -4°F. With the addition of the optional drain pan heater, the heating performance and range can be enhanced. If there is a need to keep your space cool, the cooling capabilities are great on this system as well. The system can operate in the cooling mode with outside temperatures as low as 14°F.
Each unit operates with its own remote or thermostat (depending on the units you choose), so there is no need to condition the room you are not using. The LMU18CHV can be easily installed without major renovations. Individual line sets are required for each indoor unit (sold separately), and only require about a small 3” hole for each unit. The line sets run from each indoor unit to the outdoor unit.
Standard features of the LMU18CHV outdoor unit include an energy efficient variable speed inverter compressor, defrost/deicing capabilities, three minute restart delay, and a self diagnosis system. It also includes soft start which reduces power surges on the electrical system. It operates when the outside temperature is as low as 14°F in the cooling mode and from -4°F to 64°F in the heating mode. To top it all off, it uses environmentally friendly R-410A refrigerant and is precharged for up to 49.2’ of line.
LG offers ultimate flexibility and configurability in your selection of the two indoor units required for this system. 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.
Indoor Unit Options
Standard Wall Unit (LMN078HVT, LSN090HSV5, LSN120HSV5, LMN158HVT) - The standard wall unit comes in a white finish and will blend quietly and seamlessly into any room decor.

The new HSV5 units have built-in WiFi and will be available in 2018! Available in 7,000, 9,000, 12,000, and 15,000 BTUs for use with the LMU18CHV.
Art Cool Wall Unit (LAN090HSV5, LAN120HSV5) - The Art Cool wall unit comes in a reflective, smoky black, mirrored finish that will add a modern flare to any decor, while still blending quietly into any room. Like the standard wall unit, it is installed high on a wall and connects to the outdoor compressor through a small opening drilled in your wall, behind the unit. The line set and wire (required, sold separately) connect to the compressor outside through this opening. A wireless remote is included for convenient operation anywhere in the room.

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. It is installed on a wall and connects to the outdoor compressor through a small opening drilled in your wall, behind the unit. 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)- 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, and 12,000 BTUs for the LMU18CHV.
Ceiling Cassette Unit (LMCN077HV, LCN097HV4, LCN127HV4) - 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, and 12,000 BTUs for the LMU18CHV.
