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 conversations easily. Doesn’t run up a huge power bill even though we use it a lot. Very happy.

Great for our small room. This unit heats and cools a large area without any issues, it makes a noise but nothing to complain about.

 I like the power button that heats or cools things fast; then, when it gets to temperature, the unit will slow down.

The unit is very easy to use and comes with a seven-year warranty.
