Why Choose This Model (LG AS12S0S 3.5kW Split System)?
The LG AS12S0S 3.5kW Split System provides an ideal balance of power, air reach, and smart energy management. Its 3.5 kW capacity makes it the most popular size for Australian master bedrooms, open-plan apartments, and medium living zones. By combining long-distance DUAL Vane™ air distribution with indirect Soft Air operation and proactive energy limiting, it delivers total comfort with controlled electricity expenditure.
Key Features
DUAL Vane™ Long-Reach Airflow
Dual independent air vanes split and guide conditioned air stream both upward and downward. This design cools room spaces up to 23% faster while extending total airflow throw distances up to 22 metres across larger rooms.
AI Air Smart Comfort Sensing
Using environmental metrics and location inputs via LG ThinQ®, AI Air automatically evaluates indoor temperature dynamics and optimizes supply air volume and direction to keep occupants consistently comfortable.
Indirect Soft Air Mode
When the set temperature is reached, Soft Air mode redirects discharge air away from room occupants. This creates a gentle, indirect cooling breeze that prevents chilling draft sensations during extended use.
LG ThinQ® & Voice Assistance
Factory-embedded Wi-Fi enables remote system setup, weekly scheduling, and energy usage tracking through LG ThinQ®. It seamlessly connects with smart home platforms including Google Assistant and Amazon Alexa.
Auto Clean+ & Freeze Cleaning Hygiene
Maintains pristine internal components by automatically drying the heat exchanger after use. The Freeze Cleaning feature creates a controlled frost layer on the indoor coil to lock and flush out trapped micro-dust during defrosting.
Gold Fin™ Outdoor Protection
The outdoor heat exchanger is treated with LG’s anticorrosive Gold Fin™ coating. This specialized shield resists salt spray, airborne contaminants, and moisture accumulation for improved durability in Australian conditions.
Ideal Applications
- Master Bedrooms & Suites: Quiet operational performance and Soft Air draft avoidance ensure night-time sleeping comfort.
- Medium Living Rooms & Dining Areas: 3.5 kW capacity delivers effective thermal coverage for 20–30 m² spaces.
- Apartments & Townhouses: Long airflow throw easilyConditions narrow or elongated living zones.
- Coastal Residential Properties: Gold Fin™ coil protection prevents corrosion caused by salt-laden ocean air.
