2.5 kWFujitsu Lifestyle 2.5kW Split System
The 2.5kW Fujitsu Lifestyle Split (model ASTG09KMTC) is sized for standard bedrooms and small home offices. As a guide it suits a typical insulated room of roughly 17 to 20m²; sun exposure and ceiling height move that band. It is the smallest capacity in the Fujitsu Lifestyle Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
The Fujitsu Lifestyle 2.5kW uses 155 kWh annually for cooling and 351 kWh annually for heating under Sydney's climate conditions, according to official GEMS test data. These figures reflect typical usage patterns and allow you to calculate running costs based on current electricity rates. The system carries a 5-star energy rating for cooling and 3-star rating for heating in Sydney's climate zone.
The unit achieves an AEER (air conditioner energy rating) of 4.70 for cooling and an ACOP (air conditioner coefficient of performance) of 4.84 for heating. It uses R32 refrigerant. These efficiency metrics demonstrate the system's ability to deliver heating and cooling output relative to energy consumed.

Fujitsu Lifestyle 2.5kW: your questions
How much does a 2.5kW 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. We give fixed quotes by phone or email, and photos of the wall, the outdoor spot and your switchboard get you the sharpest number.
What size room does a 2.5kW air conditioner suit?
A 2.5kW split system suits roughly 16 to 20 square metres in a typical insulated room. 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 2.5kW cost to run?
Official government test figures for Sydney's climate zone put the Fujitsu Lifestyle 2.5kW at 155 kWh a year for cooling, which works out to about $54 a year at the current Sydney median electricity rate, and about $122 a year for heating. Your bill depends on your tariff and usage, but these are the registered figures, not estimates we made up.
Is the Fujitsu Lifestyle 2.5kW reverse cycle?
Yes. The registered model (ASTG09KMTC) heats and cools, so one system covers Sydney summers and winters. Its official heating figures for this climate zone are shown in the energy section above.
