I bought 5 Daikin US7 from Pure Electric in 2014 Humidity control is the best thing about it. My energy usage has dramatically dropped and we are comfortable all year.

As of writing we've had the smallest FTXZ25N unit installed in our main living area (approx. 50 m2) for 3 years (since May 2015) to heat and cool. It's possible to check the overall total energy kWh used on the remote and it currently reads 1,585 kWh which equates to around $380 for 3 years at $0.24 / kWh.

We aren't connected to gas and this is our only form of heating and cooling in the living area. Upfront cost is more expensive but well worth it. :)

Agonised over this Daikin US7 2.5kW version for many months, but very pleased we went ahead with buying multiple units for different areas of the house. Pros: very fast to reach set temperature; relatively quiet to operate (both indoor and outdoor units); uses hardly any power (as claimed). Cons: expensive upfront cost; chunky internal unit; still haven’t figured out how to run with just ventilation only with filtered air from outside (not cooling/heating). Less enthralled about the medium sized 3.5kw unit used in larger rooms (uses a lot more power). Supplied & installed by Eastwood Air and would generally recommend them.

I love our Daikin ac and we have two. One in a bedroom and one in the main living area. Only had ducted before the split system and the Daikin is so efficient and in 40 degree Adelaide heat we stay nice and cool. Quite quiet - can watch TV and have conversation easily. Doesn't run up a huge power bill even though we use it a lot. Very happy.

Its in a kitchen, dining lounge room 7x7m, replacement for raging 7.5kW. Although it's only 2.5kW, for quick response, it can overdrive itself to 7.5kW for 20minutes. With the 7.5kW, older and less efficient that we replaced, measuring day by day for full year, even though it was less efficient, it only used 10kWh for a full day, for a pair of seniors, mostly home all day, every day.

Great for our small room
This unit heats and cools a large area without any issues, it make a noise but nothing to complain about.
I like the powerful button the heats or cools things fast then when it gets to temperature the unit will slow down. The unit is very easy to use and came with a seven year warranty.

We had our unit installed in Oct 2016 just before the Sydney summer heat wave and the unit has been wonderful! We were attracted to the 7 star energy rating and that hasn't disappointed us after reviewing the last two quarterly energy bills. Very quiet with great features. BrookAir from Kirrawee did a great installation job. A bit more expensive than other units though.
