LG DUAL Inverter Compressor™, powering air conditioning innovation

The compressor is at the heart of air conditioners and plays a vital role in compressing and circulating the refrigerant to yield cool, comfortable indoor air. LG's air conditioners leverage the powerful DUAL Inverter Compressor™, which combines two cylinders in one compressor. These industry-leading compressor technologies provide advanced air conditioning solutions.

There are LG's air conditioner and DUAL Inverter.

Powerful cooling for quick cooldowns

Just finished your workout and need to cool down fast?

LG DUAL Inverter air conditioners quickly reach the temperature you set. At high temperatures, the inverter compressor speeds up to produce more cool air. This powerful cooling is up to 40% faster, letting you quickly escape the heat.​

*Testing by TUV shows LG inverter air conditioner(US-Q242K*) cools up to 40% more faster than LG non-inverter air conditioner(TS-H2465DAO).

DUAL compressor, fast cooling

LG DUAL Inverter™ uses two compressors to compress the refrigerant efficiently, which yields speedier cooling speeds.

Well-maintained temperatures for all-around comfort

What air conditioner can steadily maintain the ideal temperature?

With non-inverter air conditioners, a fixed-speed compressor cycles between full power and off, causing temperature swings. Inverter air conditioners automatically adjust compressor speed to match your set temperature. This precision control steadily and consistently cools or heats, letting you focus on what matters instead of the thermostat.

There is a comparison graph showing that the inverter air conditioner keeps the temperature constant compared to the non-inverter, and there is a woman who is cool next to the graph.

Savings that’ll bring you relief

 Is there an air conditioner that can save energy?

LG DUAL Inverter air conditioners customize cooling output, creating a power-saving low-speed operation zone. The dual cylinder compressors optimize performance for each load. This can save up to 70% more energy. You'll rejoice in the energy bill savings.

Blissful quiet as you cool down

Need a quiet air conditioner to protect your calm?

The Dual Inverter Compressor™ reduces operating noise by balancing its two cylinders and minimizing vibration. This lets you enjoy your daily routine in peace and comfort.
