Why Choose This Model (LG AS18S1S 4.8kW Split System)?
The LG AS18S1S 4.8kW Split System is the definitive choice for open-plan living rooms, large dining zones, and master bedroom suites requiring strong, dependable climate control. By bridging the gap between compact 3.5 kW units and large 7.0 kW systems, it provides precise 4.8 kW cooling power without excessive electrical demand. With quiet operation, automated hygiene wash routines, and Smart AI airflow control, it guarantees high-efficiency comfort for demanding Australian conditions.
Key Features
DUAL Inverter Compressor Performance
LG’s dual-rotary compressor technology adjusts motor speed continuously rather than cycling on and off. This reduces friction and power consumption, enabling rapid initial room cooling and exceptionally quiet ongoing thermal maintenance.
AI Air Smart Climate Management
The integrated AI Air engine utilizes indoor temperature data and location parameters set in the LG ThinQ® app. It automatically selects the ideal airflow mode—Direct, Indirect, or Soft Air—to keep room occupants in optimal comfort.
DUAL Vane Airflow Control
Dual independent louvers direct conditioned air high toward the ceiling during cooling or low toward the floor during heating. This produces rapid air movement across open spaces without creating uncomfortable draft zones.
LG ThinQ® & Energy Manager+
Integrated Wi-Fi connectivity allows complete smartphone system management via LG ThinQ®. Homeowners can monitor electricity usage in real time, set custom operating schedules, and adjust power caps using Energy Manager+.
One-Click Scheduled & Freeze Cleaning
Maintains clean internal air channels through automated maintenance routines. The Freeze Cleaning function freezes dirt particles trapped on the heat exchanger coil and washes them down the condensate drain line during thawing.
Gold Fin™ Anti-Corrosion Defense
The outdoor condenser coil features a protective gold-colored anticorrosive surface treatment. This shield protects delicate aluminum heat exchanger fins against salt spray, atmospheric pollution, and moisture degradation.
Ideal Applications
- Open-Plan Living & Dining Areas: 4.8 kW cooling output conditions medium-to-large spaces (30–45 m²) effectively.
- Master Bedroom Suites: Soft Air mode and quiet operation ensure comfortable, draft-free sleeping conditions.
- Coastal Residences: Gold Fin™ outdoor protection provides vital resistance against harsh coastal salt spray.
- Modern Smart Homes: Embedded Wi-Fi links seamlessly with smart home platforms including Google Assistant and Amazon Alexa.
Why Professionals Choose This Model (LG AS18S1S 4.8kW Split System)?
