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.

At a glance
This Fujitsu split system is a solid mid-range option for bedrooms, studies and compact living areas needing dependable year-round cooling and heating. It stands out for Wi-Fi control, quiet indoor performance, occupancy sensing and air-freshening filters. Energy ratings are strong for cooling, but heating efficiency is more modest in colder climates than some premium specialist models.
What it’s great for
- Year-round room comfort
- Bedroom climate control
- Study and home office use
- Small living areas
- Smart home convenience
Where it works best
- Bedroom
- Study
- Home office
- Apartment living area
- Compact lounge room
Who it’s for
- Apartment resident
- Small household
- Remote worker
- Student
- Everyday home user
Things to consider
While cooling efficiency is strong, the 2.5 star heating rating in cold climates means it is not as well suited to colder regions as premium models with stronger cold-climate heating performance.
Room size suitability
Small to mid-sized rooms such as bedrooms, studies and compact living areas
Energy efficiency score
7.5/10 - strong cooling ratings at 4.5 to 5 stars, but heating efficiency is moderate at 2.5 to 3.5 stars depending on climate
Noise level vs category average
7/10 - 42dBA indoor noise is reasonably quiet for the category and suitable for everyday living spaces
Smart home integration score
8/10 - built-in Wi-Fi and remote control make it easy to manage without being a fully advanced smart ecosystem product
Allergy friendliness
7/10 - Apple-Catechin and ion deodorisation filters help with particles and odours, though it is not a specialist air purification system
Key benefits
- 3.5kW cooling capacity: Well suited to keeping small to mid-sized rooms comfortably cool during warmer weather.
- 3.7kW heating capacity: Provides practical reverse cycle heating for everyday comfort in a single room.
- Wi-Fi enabled: Lets you adjust temperature settings remotely for added convenience around the home.
- Human sensor: Adjusts operation based on room occupancy to avoid unnecessary running.
- Apple-Catechin filter: Helps capture airborne particles to support a fresher indoor environment.
- Long-Life Ion Deodorisation filter: Helps reduce odours for more pleasant day-to-day room comfort.
- Indoor noise level 42dBA: Supports quieter operation that suits bedrooms, studies and similar living spaces.
- Cooling energy rating up to 5 stars in cold climates: Delivers strong cooling efficiency, with 4.5 stars in average and hot climates.
Q: Can this Fujitsu split system cool more than one room?
A: No. This reverse cycle split system is designed to heat or cool a single room, such as a bedroom, study or compact living area. It is not the right fit for whole-home conditioning or large multi-room coverage from one indoor unit.
Q: Is the 3.5kW Fujitsu suitable for a large open-plan area?
A: No. Fujitsu SET-ASTG12KMTC-NXT is better suited to a small to mid-sized single room than a large open-plan space. In a bigger area, temperature control can feel less even and the system may need to run harder to keep up.
Q: How quiet is this air conditioner for bedroom use?
A: Fujitsu SET-ASTG12KMTC-NXT has an indoor noise level of 42dBA, which suits bedrooms, studies and other quieter spaces. The outdoor unit is rated at 59dBA, so indoor comfort is the stronger point if outside placement noise matters.
Q: Does the human sensor switch it off when nobody is there?
A: No. The human sensor adjusts operation based on room occupancy to reduce unnecessary running, rather than acting as a full power-off replacement. It is useful for rooms that are used on and off through the day, not constant empty-room shutoff.
Q: Do the built-in filters replace a separate air purifier?
A: No. The Apple-Catechin and long-life ion deodorisation filters help capture airborne particles and reduce odours inside the air conditioner, but this model is not a dedicated air purifier. Buy it for climate control first, with fresher-air support as a bonus.
Q: What do you get in the box with this model?
A: This model includes a wireless remote controller and WiFi Control in the box. That means app-based control is part of the package, rather than an extra add-on, but professional installation is still required before the system can be used.
Q: Is this model eligible for the Victorian heating upgrade?
A: No. This model is not listed as a Victorian Home Heating and Cooling Upgrade product. If rebate eligibility matters to the purchase, treat this unit as a standard retail split system rather than one sold under that specific upgrade program.
