Here are the other factors you should keep in mind when choosing a split system model:

Air Conditioning Efficiency

An easy way to gauge a unit’s efficiency is by checking its energy star rating. The energy star rating is a government initiative designed to help you make an informed decision – the more stars an air conditioner has, the more efficient it is and the less it will cost to run.

Reverse cycle systems have two star ratings – blue (to show its efficiency when cooling) and red (for heating). LG split systems also have the Active Energy Control, which allows you to cap energy consumption to improve energy efficiency and reduce power consumption.

Features and functions

Most modern air conditioners now come with advanced features, and here are just a few that you may want to look out for:

a) Air filter and purifier
LG air conditioners use several filtration systems, including the Plasmaster Ioniser, Plasmaster Auto Cleaning, and Micro Dust Filter, to eliminate unwanted odours and potentially harmful micro-particles in the air, such viruses, bacteria and allergens. The Plasmaster Ioniser also works to provide extra moisture and control humidity in the room.

b) Sleep mode
Most LG models have an auto sleep mode, which allows the unit to gradually increase the temperature to a comfortable level or turn off while you sleep. When in Sleep Mode, LG’s skew fan
and Dual Inverter Compressor also eliminate unnecessary noise to create a quieter sleeping environment.

c) Optimised airflow
The louvres on LG air conditioners are capable of multiple movements – the 4-way auto swing, the 5-step horizontal air flow, and the 6-step vertical air flow. This allows the unit to disperse air flow in multiple directions effectively and quickly, or even limit the air flow, according to your needs.

d) Wi-Fi connectivity
Air conditioners that are embedded with Wi-Fi connection can be controlled through your smartphone, which means ultimate control and convenience. With the LG Smart ThinQ app, you can
access and control your LG air conditioner with your smartphone wherever you are, even when you are not home. This can potentially save you from a hefty electricity bill, especially if you’ve left your house without turning the air conditioner off. With the Smart ThinQ app, you can simply switch it off while you’re on the road!
