3.5 kWMitsubishi Electric MSZ-LN 3.5kW Split System
The 3.5kW Mitsubishi Electric MSZ-LN Premium Split (model MSZ-LN35VG) is sized for large bedrooms and smaller living rooms. As a guide, it cools a room of up to about 25 to 29 m². That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Western sun, poor insulation and high ceilings bring it down. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 5kW.
Part of the Mitsubishi Electric MSZ-LN Premium Split range, Mitsubishi Electric's split system line, in 4 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 3.5 kW options, see every 3.5kW split system ranked by running cost, or ask about supply and installation.
About $228 a year at the current Sydney median electricity rate: $84 of cooling plus $144 of heating, from the official GEMS test figures.
The Mitsubishi Electric MSZ-LN 3.5kW uses 254 kWh annually for cooling and 435 kWh for heating, based on official GEMS testing for Sydney's climate zone. These figures form the basis of your running cost estimate, which varies with your local electricity rate. The system achieves a 4-star cooling efficiency rating and 3.5-star heating rating under the zoned energy label for Sydney.
The unit's rated cooling efficiency (AEER) is 4.25 and heating efficiency (ACOP) is 4.86, indicating solid performance across both modes. It uses R32 refrigerant. Your actual energy consumption will depend on how often you run the system and your temperature settings.
