The LG Comfort DUALCOOL EZ12CSS is a 3.5 kW single-split air conditioner with built-in WiFi. The set contains the indoor unit EZ12CSN, the outdoor unit EZ12CSU and a remote control. As an indication, 3.5 kW is sufficient for a room of up to about 35 m² with normal insulation – think of a living room, a spacious bedroom or a home office.

The big advantage of this Comfort line is how quiet it is: at the lowest setting the indoor unit comes in at around 19 dB, which you will hardly notice in a bedroom. The Dual Inverter compressor keeps the temperature stable; energy label A++ for cooling (SEER 6.6) and A+ for heating (SCOP 4.0). With the LG ThinQ app you can operate the air conditioner remotely, set schedules and view its energy use.

  • Cools and heats: 3.5 kW cooling, 3.7 kW heating
  • Energy label A++ (cooling) / A+ (heating)
  • Indoor unit from 19 dB – suitable for bedrooms
  • Built-in WiFi, control via the LG ThinQ app
  • Refrigerant R32
  • Complete: indoor unit, outdoor unit and remote control

Please note: a split air conditioner works with refrigerant and may only be connected by an F-gas certified installation company.

Questions about this product

What room size is this air conditioner suitable for?
This model delivers 3.5 kW (0.89 – 4.0 kW) of cooling capacity. As a rule of thumb, in a normally insulated home you can count on about 10 m² per kW, so around 35 m².
Does it also heat in winter?
Yes. The heating capacity is 3.7 kW (0.89 – 5.1 kW). In spring and autumn, heating with an air conditioner is usually more economical than with a central heating boiler.
How energy-efficient is this air conditioner?
Energy class A++ / A+, SEER 6.6, SCOP 4.0. The higher the SEER and SCOP, the less electricity it uses per kWh of cooling or heating delivered. Inverter technology lets it modulate its output instead of constantly switching on and off.
How quiet is it?
Indoor unit sound level: 19 – 45 dB(A). At the lowest setting that is comparable to soft rustling — fine for a bedroom.
May I install the air conditioner myself?
You may mount it yourself, but connecting and filling the refrigerant circuit is not allowed: that must be done by an F-gas certified technician. In the Netherlands and Belgium you can request an installation quote from us, or have the air conditioner connected by your own installer.
Which refrigerant does it use?
This model runs on R32. Filling and connecting the refrigerant circuit may only be done by an F-gas certified installer.
