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!

Q: What room size is this Fujitsu 5.0kW / 6.0kW split system best suited to?
A: It is best suited to a medium room. As a practical guide, a 5.0kW cooling split system usually suits about 25 to 40 square metres, depending on ceiling height, insulation, window area and whether the space is open plan.
Q: Can this model handle changing temperatures without constantly running at full power?
A: Yes. It has a wide output range, from 1.0 to 6.5kW in cooling and 1.05 to 8.7kW in heating, so it can ramp down in mild weather and lift output when conditions become more demanding.
Q: How energy efficient is this Fujitsu reverse cycle split system?
A: It is a strong performer for a mid-size split system, with an EER of 4.31 for cooling and a COP of 4.69 for heating. Cooling is rated up to 5 stars depending on climate, while heating varies more by region at 2.5 to 3.5 stars.
Q: Does the Human Sensor Control feature make a real difference in everyday use?
A: Yes. Human Sensor Control is designed to reduce unnecessary operation when the room is unoccupied, which can help lower energy use. It is most useful in spaces like living rooms or studies that are not occupied all day.
Q: Is this Fujitsu model better for a single room or for multiple connected areas?
A: This model is positioned as a single room solution and is best matched to one medium-sized area. In connected spaces, airflow and load can vary, so comfort may drop away from the main room even if capacity looks adequate on paper.
Q: Why might this model suit buyers who want stronger heating than cooling capacity?
A: Because its rated heating capacity is 6.0kW versus 5.0kW for cooling, it is biased slightly toward winter performance. That can be useful in cooler climates or rooms that lose heat quickly through glass, doors or poorer insulation.
