Easy Maintenance

The monitor view provides indicator information so that managers can check the error status.

Refrigerant temperature is maintained according to outside temperature, saving operation energy.

Mode Lock

The operating mode can be switched to either cooling or heating only by adjusting a switch on the unit.

Energy Controls

Peak current control is an optional setting that limits the air conditioning unit from running at maximum, improving operating efficiency.

Flexible Installation

Multiple piping lengths, including a long and high option, extends the amount of spaces where the outdoor units can be placed.

Great A/C from LG

I bought the LG A/C to replace Samsung one. I am also using other brands such as Mitsubishi, Fujitsu. After replacing with LG, I am so satisfied. My family also think LG a/c is better than others. Specially, design and function. It’s quite and fast to cool down the room. It’s easy to use. And its design will make even better your room.
Overall, I am so satisfied with LG product. I will definitely buy LG products again. Not just a/c, but TVs, washing machines, etc. Because I trust their name. You won’t regret with LG.
