Frequently Asked Questions
What is a duct-free split system?
A duct-free split system is a reconfiguration of a conventional central air conditioner, consisting of three basic components: an outdoor inverter-driven compressor / condenser unit; one or more indoor evaporator units; a compact conduit for refrigerant piping and wiring connecting the units. This design allows for energy conservation by targeting only those areas that need cooling or heating, a cost effective feature when only certain portions of a home/building are being used.
What is an inverter-driven compressor?
The inverter-driven compressor, housed in the outdoor unit, allows the air-conditioning system to ramp up or down to maintain comfort levels. After the set temperature is reached, the inverter-driven compressor and smart electronics allow the system to “coast,” using a reduced amount of energy to ensure that the room stays comfortable. This works much like driving your car downhill with your foot off the accelerator—the car is maintaining speed but using less gas. The inverter-driven compressor allows duct-free split systems to operate quietly, and without the surge-on and drop off energy cycles of conventional air conditioners…saving you energy.
What are the advantages of duct-free split over central air conditioning?
Central air conditioners may encounter energy losses up to 30% as the air travels through the ducts. Since duct-free split systems have little or no ductwork, they are more energy efficient than central air conditioning systems and can be installed in homes with no room for installing ductwork. The most recognized advantage of a duct-free split system is the ability control the temperature in any room with custom zoning rather than heating and cooling the entire house with a central air conditioning system. Some other leading advantages include low maintenance, increased air quality and stylish designs. Visit our Duct-Free Benefits page to read more about duct-free technology advantages.
Why should I choose a duct-free split system?
A duct-free split system delivers advance climate control and operating efficiency to a wide range of residential applications. These systems allow air conditioning an entire home or just a single room without the need for invasive ductwork. Duct-free split systems are ideal for cooling an uncomfortable bedroom, a room remodel, or when building an addition to your home where ductwork would be cost-prohibitive. There is no need to tear down walls or dramatic alterations to your home’s appearance. In most cases, a professional contractor can complete the job in less than one day.

Why should I choose an LG Duct-Free Split system?
LG offers a wide range of systems from single-zone in one-to-one configurations for single room/space solutions, to multi-zone that can support up to eight (8) indoor units for multiple room/space solutions. We offer an aesthetically pleasing line with your choice of indoor unit styles. The unique Art Cool™ Gallery is an LG exclusive offering! Visit our Why the LG Brand page for more reasons to choose an LG Duct-Free Split system.
What are the advantages of Inverter technology?
Inverter variable-speed outdoor units are measurably quieter and use less energy than conventional air conditioners. Unlike conventional air conditioners that cycle on and off, an Inverter compressor ramps up or down to match the capacity and maintain comfort levels. Once the duct-free split system satisfies room temperature, the inverter compressor and smart electronics take over and your system will “coast along” as a car will coast downhill using less gas.

What is SEER?
The HVAC industry provides information that conveys energy consumption to consumers. SEER is the acronym for “Seasonal Energy Efficiency Ratio,” a number indicating a system’s efficiency when it operates in cooling mode under certain testing conditions. The higher the SEER number, the more efficiently a system will operate. Currently, the HVAC industry’s minimum SEER number for new products is 13. LG offers duct-free split systems with SEER ratings up to 27.5. Visit our Sustainability page for more information.
What is HSPF?
The HVAC industry provides information that conveys energy consumption to consumers. HSPF is the acronym for “Heating Seasonal Performance Factor,” a number indicating a system’s efficiency when it operates in heating mode under certain testing conditions. The higher the HSPF number, the more efficiently a system will operate. Currently, the HVAC industry’s minimum HSPF number for new products is 7.7. LG offers duct-free split systems with HSPF ratings up to 11.8.
Are LG Duct-Free Split indoor units available in various colors?
Most wall-mounted LG Duct-Free Split indoor units have an off-white or pearl white finish. The Art Cool™ Mirror wall-mounted indoor units have a shiny black finish. The Art Cool Gallery indoor units have a black boarder that frames a display window for your choice of inter-changeable art. Visit our Product pages for more details on available options for our duct-free split product line.
Do LG Duct-Free Split systems come with a warranty?
Yes. Most LG Duct-Free Split systems come with a limited warranty that covers up to five (5) years on parts and up to seven (7) years on the compressor. Visit our Warranty, Parts & Service page for more information.
Who can I contact for technical support?
