New Fujitsu Air Conditioner - Best Ever
As always, another great product from The Good Guys. This air conditioner was to replace my old 20 year old Electrolux one. The features of the Fujitsu C5.0kW H6.0kW Reverse Cycle Split System are wonderful, it is very quiet, cools rapidly and has the myanywAiR Next feature which allows wifi connection to your phone to enable you to turn on your air conditioner remotely.

Bought this system for our bedroom and absolutely love it!, it’s quiet, easy to use and can put a secondary controller on your phone, which is actually easier to use than the remote control it comes with, great product!

At a glance
This Fujitsu reverse cycle split system is a solid mid-range choice for medium rooms between 25 and 40 square metres, with strong cooling and heating, Wi-Fi control and helpful air filters. It suits homes wanting everyday comfort without overcomplicating operation. The human sensor and inverter compressor add convenience, but it is not the quietest or most heating-efficient option compared with more premium models.

Things to consider
Heating efficiency is more modest than some premium split systems, with a 3 star heating rating in average climates, so buyers focused on top-tier winter performance may prefer a higher-rated model.
Room size suitability
Best suited to medium rooms of approximately 25 to 40 square metres
Energy efficiency score
7.5/10 - strong 4.5 star cooling efficiency in average climates, but heating efficiency is more moderate at 3 stars
Noise level vs category average
6/10 - indoor noise of 46dB is reasonable for the category, though not especially quiet versus premium low-noise models
Smart home integration score
7/10 - built-in Wi-Fi control adds useful remote access, though broader smart ecosystem support is not specified
Allergy friendliness
7/10 - Apple-Catechin and ion deodorisation filters help support fresher indoor air, though it is not positioned as a specialist allergy-focused system
Key benefits
- 5.0kW Cooling Capacity: Delivers effective cooling for medium-sized rooms, making it well suited to spaces around 25 to 40 square metres.
- 6.0kW Heating Capacity: Provides strong reverse cycle heating for everyday comfort in cooler conditions.
- Inverter Compressor: Adjusts output to match room conditions, helping maintain steadier comfort instead of always running at full power.
- Human Sensor: Can reduce operation when the room is unoccupied, which is useful for spaces not used all day.
- Wi-Fi Enabled: Lets you change settings remotely for easier day-to-day control.
- 24 Hour Timer: Supports flexible scheduling so the system can start or stop around your routine.
- Apple-Catechin Filter: Helps support fresher indoor air by assisting with airborne particle capture.
- 4.5 Star Cooling Energy Rating: Offers strong cooling efficiency in average climates compared with many standard split systems.
Q: Is this split system quiet enough for a bedroom at night?
A: Fujitsu SET-ASTH18KMTD-NXT runs at 46dB for the indoor unit, which is reasonable for a bedroom or study. It is not a low-noise specialist model, so very noise-sensitive sleepers may still prefer a quieter premium unit.
Q: Can I control the Fujitsu air conditioner from my phone away from home?
A: Yes. Fujitsu SET-ASTH18KMTD-NXT is Wi-Fi enabled and includes WiFi Control, so settings can be changed from a phone when you are away from home. Broader smart home or voice assistant support is not listed for this model.
Q: How efficient is this model for cooling compared with heating?
A: Fujitsu SET-ASTH18KMTD-NXT has a 4.5 star cooling rating and a 3 star heating rating in the average climate. That means its efficiency is stronger on cooling than heating, so the main running-cost advantage shows in warmer months.
Q: What does the human sensor actually do on this model?
A: The human sensor can reduce operation when the room is unoccupied, which suits spaces that are not used all day. It helps cut unnecessary running time, but it does not replace manual scheduling or the 24 hour timer.
Q: Do the built-in filters replace a dedicated air purifier?
A: No. Fujitsu SET-ASTH18KMTD-NXT uses Apple-Catechin and long-life ion deodorisation filters to help keep indoor air fresher during heating and cooling. It is not positioned as a specialist air purifier or advanced allergy-focused filtration system.
Q: What is included in the box with this Fujitsu split system?
A: The box includes a wireless remote controller and WiFi Control for app-based access. Installation is not a DIY job, because this split system has no user-serviceable parts and must be installed by authorised service personnel.
