What You Need to Know about Ducted Split Systems

What is Inverter Technology?

Inverter technology refers to the compressor within the outdoor unit of the air conditioner. The two most common types of compressors are the fixed speed compressor and the variable speed (inverter) compressor. The fixed speed will run at 100% of its capacity and will stop and start automatically to maintain the desired temperature. An inverter compressor will vary its speed in order to maintain a consistent temperature.

More Powerful

With a wider range of temperature modes for heating and cooling, the inverter is able to operate in even the most extreme outdoor temperatures. An inverter compressor can also operate faster than non-inverter air conditioners thus allowing the air conditioner to reach the set temperature faster and bring you comfort sooner.

More Economical

An inverter's capacity will fluctuate in order to match the air conditioning requirements, so an inverter can be more energy efficient than a fixed speed compressor, as it does not stop and start its motor continually.

More Comfortable

When the air conditioner is initially activated to either heat or cool, the compressor will operate at maximum speed to reach the desired temperature quickly. Once the desired temperature is achieved, unlike non-inverter air conditioners that turn the compressor on and off, LG inverter units adjust and constantly vary the compressor speed to maintain the desired temperature with minimal fluctuation to ensure that your comfort is not compromised.

Quick Cooling & Heating

Inverter air conditioners can operate their compressors faster to give them more powerful performance. This results in being able to attain the desired temperature much faster in both heating and cooling modes than non-inverter air conditioners.

What is Durable Coating?

Gold fin™ is an anti corrosive coating on the surface of the heat exchanger in the outdoor unit. The coating is designed to protect air conditioners from pollution and corrosive conditions and assists in the durability and longevity of the unit. This technology is an ideal solution for Australian outdoor conditions.

GoldFin™‚ is an anti corrosive treatment on the surface of the heat exchanger in the outdoor unit. The treatment is designed to protect air conditioners from pollution and corrosive conditions and assists in the durability and longevity of the unit. This technology is the ideal solution for harsh Australian outdoor conditions.
Weekly Program
The operator can set the timer and program the air conditioner for a period of one week.
Long Distance, High Elevation Piping
Our LG Air Conditioners (Cassette and Concealed duct models) can be installed over a long distance(Max 50m) and a High Elevation(30m), between indoor and outdoor units.
Child Lock Function
This function prevents little hands from tampering with the control buttons on the unit. All the buttons on the indoor display panel will be blocked.
