What Is DualCool Technology in an LG Air Conditioner?
LG's DualCool is the brand name for LG's inverter split system air conditioner range in Australia. If you're shopping for an LG air conditioner and wondering what DualCool means and what makes it different from a standard air conditioner, this article explains everything you need to know.
What Does DualCool Mean?
"DualCool" refers to the dual function of LG's inverter split system air conditioners — they provide both cooling in summer and heating in winter from the one unit. This is also called a reverse cycle air conditioner.
The "dual" in DualCool describes the two operating modes:
- Cooling mode: Removes heat from the indoor air and transfers it outside
- Heating mode: Extracts heat energy from outdoor air and transfers it inside (even in cold weather)
Key Technologies in LG DualCool
Dual Inverter Compressor
LG's Dual Inverter Compressor is the centrepiece of the DualCool range. Unlike a conventional fixed-speed compressor that runs at 100% or off, the Dual Inverter operates at variable speeds matched to the room's actual cooling or heating demand. The benefits are:
- Up to 70% more energy-efficient than a conventional non-inverter unit
- Faster cooling and heating (reaches target temperature up to 40% faster)
- Quieter operation (runs at lower speed most of the time)
- Longer compressor lifespan (backed by LG's 10-year compressor warranty)
Dual Protection Filter
The DualCool range includes a Dual Protection Filter with an anti-bacterial coating on the pre-filter. This helps reduce allergens, dust and bacteria circulating through the indoor unit.
UVnano (Selected Models)
Some higher-end DualCool models feature LG's UVnano technology — a UV-C LED light mounted on the fan blade that sterilises bacteria and viruses on the fan as it rotates during operation. LG claims this removes up to 99.9% of bacteria from the fan within 30 minutes of operation.
ThinQ / Wi-Fi Control
Most LG DualCool models are ThinQ-compatible, which means they can be controlled via LG's ThinQ app on a smartphone. Features include remote on/off, temperature control, scheduling, and integration with LG's smart home ecosystem and voice assistants (Google Home and Amazon Alexa).
