LG S4-Q09WAQAL 1 Winner Inverter, Dualcool Inverter, Energy Saving, Faster Cooling

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.

• 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.

A split system needs an outdoor unit and pipework, so check the wall you plan to use and the route outside before fitting.
