Samsung vs LG Air Conditioner: A Genuine Comparison
Samsung and LG are two Korean electronics giants that both make popular split system air conditioners for Australian homes. They're often compared because they compete at similar price points and both offer strong technology and smart home features. This guide compares Samsung and LG split systems across the factors that matter for Australian households.
Brand Overview
Samsung
Samsung is one of the world's largest electronics companies. Their air conditioner division offers split systems that are well-regarded for energy efficiency, innovative features and integration with the SmartThings smart home ecosystem. Samsung AC units are competitively priced and widely available in Australia.
LG
LG is another Korean electronics powerhouse. LG's air conditioner range is known for its Dual Inverter Compressor technology, which is designed to deliver faster cooling, greater energy efficiency and quieter operation compared to single inverter models. LG AC units are also widely available and competitively priced.
Key Comparison: Samsung vs LG Split System
| Feature | Samsung | LG |

| Noise level (indoor) | 19–26 dBA | 19–25 dBA |
| Wi-Fi control | Yes (SmartThings app) | Yes (LG ThinQ app) |
| Air purification | Triangle Design with auto-cleaning | UVnano on select models |
| Refrigerant | R32 | R32 |
| Price range 2.5kW (AUS) | $900–$1,500 | $900–$1,500 |
| Warranty (AUS) | 5 years | 5 years |
Cooling and Heating Performance
Both brands perform comparably in Sydney's climate. The LG Dual Inverter Compressor is claimed to reach set temperature faster than a single inverter and to maintain it more precisely, which can translate to slightly lower energy use over time. Samsung's Digital Inverter is also efficient but uses a more conventional single inverter design.
Smart Home Integration
Samsung SmartThings is one of the most capable smart home ecosystems available, integrating with a huge range of Samsung and third-party devices. If you already have Samsung smart home products, adding a Samsung AC is natural.
LG ThinQ is similarly capable and integrates with Google Home, Amazon Alexa and Apple HomeKit. If you use a non-Samsung smart home setup, LG ThinQ may offer better compatibility.
Air Quality Features
Samsung's newer models include an Auto Clean function that dries the indoor unit's heat exchanger after use to prevent mould and odour. LG's UVnano (available on select models) uses UV-C light to sanitise the fan blade, reducing bacteria and allergens.
Which Is Better Value?
At similar price points, LG and Samsung are very closely matched. The main differentiators are:
- LG's Dual Inverter Compressor may deliver slightly faster cooling and marginally better efficiency over time
- Samsung's SmartThings ecosystem is broader if you're invested in Samsung products
- LG ThinQ offers better compatibility with Apple HomeKit and other non-Samsung platforms
Who Should Choose Samsung?
- You already have Samsung smart home products
- You value the SmartThings ecosystem and broader device integration
- You prefer Samsung's design aesthetic
Who Should Choose LG?
- You value the Dual Inverter Compressor's efficiency claims
- You use Google Home, Apple HomeKit or Alexa (better native integration)
- You prefer LG's design or already own LG products
