Amazing service
I knew what I wanted due to previous experience with fujitsu. Good Guys gave me the best price and they arranged its installation. Everything went well from installation to now using it on the hot days.

Reliable & Featureful
Simple to use .. Powerful & quite.. A little more expensive than other brands but well worth the difference in cost .. Fujitsu makes a well designed product. Have already ordered another two units for additional rooms.

Key benefits

- 3.7kW Heating Capacity: Provides reverse cycle heating for comfortable year-round use in the same room.
- Wi-Fi Connectivity: Lets you adjust temperature and settings remotely for added convenience around the home.
- Human Sensor: Detects room occupancy and adjusts operation to help avoid unnecessary running.
- Apple-Catechin Filter: Helps capture dust and airborne particles to support a fresher indoor environment.
- Long-Life Ion Deodorisation Filter: Helps reduce odours so rooms feel fresher during everyday use.

Q: What room size is the Fujitsu C3.5kW H3.7kW split system best suited to?
A: It is best suited to a small to mid-sized single room, such as a bedroom, study or compact living area. Its 3.50kW cooling and 3.70kW heating capacity are positioned for single-room comfort rather than open-plan whole-home coverage.
Q: Is this Fujitsu split system an energy-efficient option for everyday use?
A: Yes. It has a 4.5 star cooling rating in hot and average climates, plus a 5 star rating in cold climates, with cooling input power rated at 0.89kW. Heating input power is rated at 0.79kW, so it is designed for efficient day-to-day use.
Q: What does Human Sensor Control do on this Fujitsu Lifestyle Next model?
A: Human Sensor Control helps reduce energy use by adjusting operation when the room is unoccupied. On this Lifestyle Next model, it works with economy mode and weekly timers, so it is useful if the room is used at set times rather than all day.
Q: How does this model perform for heating compared with cooling?
A: It offers slightly higher rated heating than cooling, at 3.70kW versus 3.50kW, so it is built for year-round reverse cycle use. Heating efficiency varies by climate though, with heating star ratings dropping in colder conditions compared with cooling.
Q: Is the Fujitsu SET-ASTG12KMTC-NXT a good choice for one room rather than multiple rooms?
A: Yes. This is a wall mounted single-room solution with one indoor unit, designed to condition one main space rather than several rooms at once. If air needs to reach hallways or adjoining rooms, performance will be less consistent than in the main room.
