I had this unit for about 2 years and from about half year ago every time when i turn on and turn off the unit, there are strange noise like plastic being hit or crushed, or the fins cools down after heated or I don't know what actually makes the noise. The noise is actually quite loud it goes for a while even few minutes after shut still appears once or twice. I am not sure if this is under warranty. Do you guys have the same issue???. Thank you

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.

We installed a Panasonic 7kw system 18 years ago and we had no hesitation in replacing it with this system it is very economical to run with a 4 star rating and very quiet. It is well priced too.

All I can say is to previous reviews it's not the unit and read the manual.
This is one of the most energy efficient heat pumps on the market and this model hits a sweet spot for that efficiency. The next model down and up not so efficient.
Getting the right size go 55 to 65watts per cubic meter
They take time to start because they don't want to blow cold air at you also it can be the new energy efficient r32 gas but most heat pumps take time to start.
You can ajust the brightness of the led by pressing I think the up button for 5 seconds it's in the manual.
So if it's not heating it's probably to small for your room.
Which is a shame because this model is a good one.

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.

installed May 2018. Does not heat past 19-20 degrees, i nearly froze to death in melb.,
Give me my refund as you promised. Panasonic faulty product... 5 tech visits to no avail...
Promises promises. Still waiting. Stand by your products and customers..been waiting for heat since May, through Melbourne winter...faulty product.

I bought this air conditioner because it has the best energy rating compared to others the same size. It works great and heats up the room in no time. I still don't understand how the Econavi works though. It also has the Nanoe G function which helps to remove bacteria from the filter.
The only thing that I don't like about this air-con, is that it makes a ticking noise when it's on, and that can be annoying sometimes, I think it's caused by the vibration of the flaps.

Can cool the house down very quickly with either Auto or Powerful mode.
The air conditioner is very quiet both inside and out compared to our previous air con.
Very easy to use, am looking at purchasing a smaller Panasonic unit for a spare bedroom too.
Would recommend it. Installation through Harvey Norman was very good too

Unit cools our 6x5m loungeroom down quite quickly and is super quiet. Purchased on eBay through good guys and picked up Unit next day. Got 20% off with ebay deal which brought the aircon down to $1070. Unit is easy to use and am very happy with our purchase. Only got installed today 28/12/2017 so am yet to have any flaws with the unit. Will see how much it increases the power bill with our next bill

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