Why Choose the LG DUALCOOL Special MJ?
Practical, efficient comfort for everyday rooms. Where a feature is model specific we say so, and we confirm exactly what's included on the capacity you choose.
Energy-Efficient Heating & Cooling
LG's inverter compressor technology automatically adjusts its output to maintain your chosen room temperature, helping reduce unnecessary energy consumption compared with conventional fixed-speed systems. Enjoy comfortable cooling in summer and efficient heating during winter.
Quiet Indoor Operation
Designed for residential comfort, the DUALCOOL Special MJ operates quietly at low fan speeds, making it a practical choice for bedrooms, home offices and living spaces.
Fast Temperature Control
Powerful cooling and heating modes help bring your room towards the desired temperature quickly, so you can enjoy a comfortable environment without unnecessary waiting.
Comfortable Airflow
Adjustable fan speeds and airflow direction allow you to tailor the system to your room and personal preferences.
Modern, Minimalist Design
The clean white indoor unit offers an understated appearance that complements a wide range of interiors, and its wall-mounted design helps preserve valuable floor space.
Convenient Everyday Controls
Simple operating modes make it easy to adjust temperature, fan speed and heating or cooling settings. Smartphone connectivity and additional features are confirmed against the exact model supplied.

Modulates its output to hold a steady room temperature
The LG DUALCOOL Special MJ uses heat pump technology to provide both heating and cooling. This makes it a versatile option for year-round comfort, whether you want to cool a bedroom during warm weather or provide efficient supplementary heating in winter.
Because the inverter compressor modulates its output rather than switching on and off, the system can hold a room at temperature without running flat out, which is where the running-cost benefits over autumn and winter come from.
Rather than applying one figure across the range, we confirm the published SEER, SCOP and energy label figures for the LG DUALCOOL Special MJ model and capacity you choose, along with the effect of the climate, your electricity tariff and how the system is used.
