6 kWFujitsu Comfort 6kW Split System
The 6 kW size of the Fujitsu Comfort Split cools a room of up to about 45 to 50 square metres as a guide. 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. We confirm sizing from your details and photos, or on a site visit, before quoting.
Part of the Fujitsu Comfort Split range, Fujitsu General's split system line, in 6 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 6 kW options, or ask about supply and installation.
About $459 a year at the current Sydney median electricity rate: $164 of cooling plus $295 of heating, from the official GEMS test figures.
The Fujitsu Comfort 6kW uses 494 kWh per year for cooling and 889 kWh per year for heating, based on GEMS registration test figures for Sydney's climate zone. The system carries a 3.5-star energy rating for cooling and a 2-star rating for heating under the zoned energy label. Running cost depends on your local electricity rate and usage patterns.
