7.1 kWFujitsu Lifestyle 7.1kW Split System
The 7.1kW Fujitsu Lifestyle Split (model ASTG24KMTC) is sized for open-plan living and dining areas. As a guide, it cools a room of up to about 51 to 59 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. It sits in the upper half of the Fujitsu Lifestyle Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 8.5kW.
Part of the Fujitsu Lifestyle Split range, Fujitsu General's split system line, in 7 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 7.1 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $539 a year at the current Sydney median electricity rate: $196 of cooling plus $343 of heating, from the official GEMS test figures.
The Fujitsu Lifestyle 7.1kW uses 593 kWh annually for cooling and 1034 kWh for heating, based on official GEMS testing in Sydney's climate zone. These figures form the basis of your running cost estimate, which updates automatically with current Sydney electricity rates. The system carries a 3.5-star cooling efficiency rating and 2.5-star heating rating under the zoned energy labelling scheme.
Efficiency is measured by AEER for cooling (3.41) and ACOP for heating (4.18). The unit operates on R32 refrigerant. Your actual energy use will vary depending on how often you run the system, the temperatures you set, and factors like insulation and ventilation in your space.

Fujitsu Lifestyle 7.1kW: your questions
How much does a 7.1kW split system cost installed?
The unit is only part of the cost. Installed price depends on whether it is a straightforward back to back installation or needs longer pipe runs, wall brackets or a condenser slab, plus any electrical work at the switchboard. You get a fixed price in writing before any work starts. Photos of the wall, the outdoor spot and your switchboard help us price the job, and if it needs a look first, we book a site visit.
What size room does a 7.1kW air conditioner suit?
A 7.1kW split system cools a room of up to about 51 to 59 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. Strong afternoon sun, high ceilings or big glass areas push you toward the next size up, and oversizing wastes money on short cycling. The capacity calculator sizes your room in under a minute, and we confirm before we quote.
How much does the Fujitsu Lifestyle 7.1kW cost to run?
Official government test figures for Sydney's climate zone put the Fujitsu Lifestyle 7.1kW at 593 kWh a year for cooling and 1,034 kWh for heating.
