Key Features

Flexible Installation

Pre-Set Comfort

A downloadable ThinQ® App allows users to access and control air conditioners with your smartphone. This means you can turn the system on remotely and come home to comfort.

Voice Control Optional

Smart technology can be utilised, allowing users to turn the air conditioner on and to check or change the unit’s temperature with the use of their voice.

External Static Pressure Control

This function allows the BLDC motor to control fan speed and air volume regardless of external static pressure.

Home Connectivity

The optional LG Modbus RTU gateway can be used with a home automation system to control lighting, climate, entertainment systems and appliances.

High Drain Pump

An inbuilt high head drain pump automatically drains water up to a height of 700mm of drain-head height.

Discrete Appearance

Only the grill and the outside unit are generally visible, allowing the ducts to blend in with most décor.

As I now own a number of house and units I rent I had my share of problems with air cons. Touch wood I have not had a problem with the 6 LG units I have got.

These new units are great. Cooling and heating work very well. The deluxe controller is good and easy to work. The units are very quiet and economical to run.

I love my LG aircon, it does what it’s supposed to – heats or cools, quickly as well. Would definitely buy another one.

It wasn’t expensive compared to other brands that do the same thing.

Have had it 4 years and it did break about 6months ago, was a split pipe in the machine however the warranty repairer came out within a week or so & it didn’t cost me a cent. Aftersale service was great.

Excellent Value for large areas

We’ve had this installed and going for the last one week and on the one hot and humid day we had it did an amazing job. The unit cools quickly and the 4 litres of condensation that it drained out in 1.5 hours is testament to the chilling capacity of the compressor and evaporator coils. I ended up watering my plants with that.
