The LG S4-Q09WAQAL is a split air conditioner. The indoor unit mounts high on the wall and sends cooled air across the room through a full width vent, while the compressor sits outside. LG lists this model among its split ACs for smaller rooms.

Key Features

The room cools down fast after you switch it on. LG’s Dual Inverter compressor technology, marked on the front of the unit, is built to bring a room down to temperature quickly.
Lower electricity use while it runs. The inverter compressor varies its speed instead of switching fully on and off, which LG states reduces energy consumption on its split ACs.
Quiet enough to sleep or work beside. LG lists quiet running as a characteristic of its split AC range.
Matched to smaller rooms. LG groups the S4-Q09WAQAL with its models for compact spaces such as a single bedroom or a small office.
Frees up floor and window space. The indoor unit fixes to the wall above head height, so nothing stands in the room and no window is blocked.
