LG Monosplit Wall Air Conditioners

Which LG monosplit wall air conditioner is right for your room?

An LG monosplit wall unit cools in summer and heats in winter with a heat pump for a single room: one indoor unit linked to an outdoor unit, quick installation and low running costs thanks to Dual Inverter technology and R-32 refrigerant. The range covers 9000 to 24000 BTU across 145 models, from around 260 euros. For most living rooms the 12000 BTU Libero Smart remains the most balanced pick, and it is one of the most popular models in Germany, where LG is the number one brand.

The room you can never cool down

The attic bedroom that turns into an oven in July, the south-facing living room where the fan only moves warm air, the office where the heat kills your focus. It is usually one specific room ruining your days, not the whole house, and for that the LG monosplit wall unit is the simplest, most affordable answer: sorted in a few hours, with no major building work.

The most popular LG series

The Libero Smart series is the most chosen, with built-in Wi-Fi and excellent efficiency for people who want to spend sensibly. The Libero Compact goes for a smaller outdoor unit for narrow balconies, the Dualcool adds advanced features and quieter running, while the Artcool turns the unit into a design object. All use R-32 refrigerant and Dual Inverter technology, and run as a heat pump.

How many BTU per room

The wrong size gets expensive: too much power keeps switching on and off and wastes electricity, too little never cools.

• 9000 BTU: bedrooms and studies up to about 25 sqm, for cool, quiet sleep;
• 12000 BTU: living rooms up to about 35 sqm, the most chosen size;
• 18000 BTU: open spaces or very sunny rooms up to about 45 sqm;
• 24000 BTU: large rooms that struggle to cool.

How much does it cost to run?

This is the question that stops almost everyone. Dual Inverter technology modulates the power with two rotors instead of switching on and off, so it uses far less than an old unit; with R-32 refrigerant and an energy class up to A+++, the bill stays under control even with cooling on all afternoon.

It heats in winter too

Because it is a heat pump, the same unit warms the room in the mid-seasons within minutes, often for less than an electric heater running for one room. For hot water instead, see the heat-pump water heaters.

LG and the connected home

With built-in Wi-Fi and the LG ThinQ app you turn the cooling on from your phone before you get home and find the room already cool, or control it by voice. Find all compatible models among the smart air conditioners for Alexa and Google Home.

LG versus other brands

Against premium brands like Daikin and Mitsubishi Electric, LG offers Dual Inverter technology and a compressor warranty of up to 10 years at a more accessible price: it is the number one brand in Germany and very strong in France precisely for this balance of technology and efficiency. To compare, also look at Samsung, Hisense and Haier.

Incentives, warranty and support

Buying a high-efficiency heat-pump unit may qualify for energy-renovation incentives depending on the schemes in force: keep your invoice and paperwork and check the current conditions. Every LG unit ships with the official manufacturer warranty, often up to 10 years on the compressor, delivery across the country and our help choosing size and kits. For several rooms, look at the wall air conditioners as multisplit or a trial split wall system, and check the deals on all air conditioners.
