Very quiet and the powerful mode is useful to get on top of the heat when I first come home

Replaced an existing split system with this product and the noise reduction was amazing. Other than that it works as advertised and easily cools the recommended room size.
I live in North Queensland so obviously I can’t comment on it’s heating performance.
One thing to note with split systems is that I’ve had multiple issues with installations, so I think we should make sure we are not blaming manufacturers for installer mistakes.

Cools down and heats up quite well, but strange noise bothers me

I sleep like a baby. It is not noisy, then again I am a heavy sleeper. I got it installed the same day. I get so cold sometimes I have to turn it off. Because turning it down won’t help. My niece loves to sleep in my room. She uses it as well.

Great performance despite temperature setting nuances

Bought and set one of these up for my MIL based on a having happily owned three earlier models of these air conditioners ourselves. Have only used it through winter so far but it can certainly put out a good amount of heat quietly. The only gripes we have with it is that it takes a good 8-10 minutes from turn on before producing any heat, which is longer than our models take and that to get a given room temperature you need to set the air con at 3-4C higher than you actually want. Otherwise, it is a fantastic product.
