In the WA desert, where the dust is thick, the temps reach 45+ for weeks and the aircons never get a rest, these units never seem to complain. We had used many other brands (including most of the popular ones, Daikin, Panasonic, Fujitsu etc) but none come close to the reliability of the MHI units.
well priced (mid range)
Good looking
Quiet and efficient
If they have a downside I am yet to notice.

I love it!!!


I only had this unit installed 4 weeks ago so I can only speak so Far. So far it seems to be working beautifully! It’s very cool to the point I can actually turn it off once the room is cold, having said that it is only spring so I’ll have to wait and see how it performs during summer. The outside fan is really quiet almost silent which is a pleasant surprise as I was expecting it to be noisy. Overall I am extremely satisfied with my beautiful new air conditioner!! It’s the first time I’ve ever had one :)

Its quite unit, bearly hear it.
We had it installed by a friend was found it easy and probably took a few hours. The remote control is easy to use.

Quiet and powerful


I've only had for a day but so far I'm very pleased. After my 10 year old LG reverse cycle broke down I had it replaced with this unit. It has an extremely quiet fan setting but is able to churn out the cold air with ease.It is easy to use the remote with large print and straight forward worded descriptions rather than cryptic symbols. Installation was just over an hour given all the infrastructure was in place but there were no problems. I haven't had the opportunity to try heating cycle as it is Summer but I anticipate it will be very effective. The guy who installed it said it will probably last longer and be more energy efficient than the old LG. The price was very reasonable as well. So far I highly recommend.

Perfect air-con covering two room's area


Happy with the colling performance. The unit is quiet. Installation was held by an independent installer - back-to-back. The unit is easy to use. Convenient Sleep function.
Got the quotation from Gumtree, the installer sells the units and kindly gave me a cash back voucher. I even got $100 back.

Good little split system


This unit has been installed into a larger bedroom with high ceilings (approx 18m^2) and has performed very well considering it's smaller size. The system cools the room quickly and quietly and has made it through the worst of summer with no hiccups.
Only issue is the back-to-back installation gives some audible vibrations when under heavy load, but suspect this is more to do with the location of the installation rather than any issue with the unit.

Good model. Low on power


Very good model. Got it when it was during the clearance period. Very powerful for a small unit and energy efficient.
It's very quiet compared to the Fujitsu 2.5kw model which I have in my bedroom.

Power consumption on high is about 600kw (base on my solar power smart meter).

Feature wise, this unit comes with 3D fan blades where it can go up and down, left and right.

The only downside for this unit is that, the gas is the older form which is not too environmental friendly.

This unit has only been in use for a short time, but very happy with the performance. Easy to operate, looks good on the inside as well as the outside very neat and tidy. Cools the house beautifully, cannot comment on heating as we are in the summer season.Our installer stated that our electricity bill will be lower, cheaper to run in the winter months as opposed to gas heating which we now use.. One happy customer!

Best ever after we had to replace our air con!


Deliberated whether to go with the 8kW or 9.2kW and am so happy we choose the bigger model. Heats up all the areas we need! Very quiet too. Also very happy with the the person who did the installation! Kept instructions simple. Was VERY happy we had this air con the recent 40+ degree day in Melbourne!

Great unit - complicated controls


Unfortunately had to replace an old email air system that would have done at least 25 years, but fortunately found this amazingly quiet Mitsubishi split system. It covers my lounge room with ease. The worst problem is there are a million settings on the remote control... Mitsubishi can you please simplify that device as it's horrid and it takes two presses of the on button to get the machine working...once again it is a dream machine when operating

Need to feel it cool and hot all in the room


I had this unit installed as my old Aircon packed up, so the Electrician recommended getting the Mitsubishi and they buy them in only to install as they said they have not had any problems with them. But I have moved the direction that the air comes into the room and if you sit in front you feel it but my seat is at the side and I don't feel it, so bit disappointed but I don't think I would buy another if any of my others pack up.

Top of the Line. Another excellent product from MHI


These units are top of the line. Surprised how quiet the 8.0kw unit is. Have it mounted on the living room wall and cannot hear it from inside at any level. Have used MHI throughout our whole house and never had a problem. The way the outdoor unit is constructed seems like a bit stronger than normal split systems, like a commercial unit.

Cool and warm


We wanted to get an air-con that actually works. The previous one we got never really cools down the room after some time. This model works. And it's easy to use. The remote control makes it so much easier. It has no noise but the installation fees were high. You should call around for installation before settling.

Quiet Air Conditioner


The recent hot summer convinced me to buy an air conditioner for my bedroom/ensuite. Having recently bought a Mitsubishi fridge, I decided to stick to a Mitsubishi Air Con. The installation went very smoothly, thanks to easy access to a balcony via the top of my built in wardrobe. The unit is very quiet & cools the room down quickly. I generally turn it on about 30 minutes before I go to bed & turn it off after reading in bed for another 30 minutes, before going to sleep. I use similar timing when using the heating in winter. The remote works well & the air con holds the temperature well, once the room is up or down to the set temp.

Very happy with this air con!

Nice AC, cools the living area well


We purchased this AC for installation at an investment property. It was installed in the living room of the granny flat & has been cooling not only the living area but also the bedroom if the bedroom door is kept opened. Tenants are pretty happy with the choice & so are we :)

Fantastic air con, very quiet and so cool


This air con is perfect for our open plan living/kitchen/dining room (total area roughly 80m²). Very quiet, easy to use, keeps us cool during the summer. Highly recommend this air con for anyone looking for one, great brand and company. Modern looking design also blends in well with our modern room settings.

Saved our lives summer of 2017!


It is so quiet. I have to check if it's on. Very easy to use. It is the best air/con I have ever had. I was surprised how economical it is. My electricity bill was much cheaper after summer than other years. Now it is colder I am impressed how quickly it heats the room.

Simply Wonderful


My new Mitsubishi Air- Con is a replacement for a failed different brand model and is simply wonderful. Thanks to it's cool quiet performance my hubby and I can get through this summer's awful heatwave in absolute comfort. The installation process was quick with zero problems and the unit is easy to use. I already had a smaller Mitsubishi air con in my bedroom so it was a logical choice to replace the old other brand with another Mitsubishi. Thank you for a great product.

Hi Jen, You can download our handy room sizing chart, which will give you a good indication of what size unit you may need here - https://mhiaa.com.au/document/srkdxk-room-sizing-chart/. Our Avanti or Avanti PLUS series would likely be suitable. You can learn more about this models here -https://mhiaa.com.au/products/category/residential/split-systems/. We'd also recommend speaking to an authorised installer who can properly size up your space and provide a recommendation. You can find your local authorised dealer here - https://mhiaa.com.au/where-to-buy. Hope this helps!

I had a 2.5kW DXK09ZMA-S installed Jan 2017_The installer fitted a condensate pump which after about 3 months went very noisy and turned on whether the ac was running or not, for random periods often between midnight & dawn and during the day. My complaint to the installer saw another pump installed{????} and was informed there would be noise. Subsequently the pump became noisy again, and power to the system was turned off. After about 18 months of phone calls the pump works noisily but the system wont go on. The pump runs very hot and appears to be pumping nothing except atoms of hope_ PLEASE EXPLAIN---- Max Herman

Hi Max,

While we're sorry to hear of the issues you're having with the pump on your unit, without having one of authorised service agents inspect the unit, it's had to tell what the issue might be.

I'd suggest jumping onto our website and submitting a warranty service request and one of service agents will organise to come and assess the unit for you. https://mhiaa.com.au/consumer-help-centre/warranty/warranty-service-request/

Thank you for your concern and I will consider your statement as I have already spoken to MHI. It appears that a non MHI pump is sanctioned for fitment with the AC unit and supposedly there is no {???} warranty involved except that on the pump! Note the word SANCTIONED!! it appears that with a 12 month life warranty I may be up for at least another $900 -$1200 depending on the whims of the installer who has replaced it once and has still not responded to even look at it again despite calls by both my wife & myself for more than eighteen {18} months. He should have at least called into inspect it! An inspection was arranged by myself following conversation with Chris {95443400} at MHI for TCB {0439-753-101} of Corio{Geelong} and it appears the same Thing will happen with a bill in excess of $600+{approx.} for rectification of improper wiring and now a request for a power point to be installed in the ceiling space. At this point my intention is to contact Consumer Affairs to report this state of affairs and seek full redress. Note I have not had the use of this AC unit until TCB got it temporarily operative before final rectification following above mentioned details. to say we are unimpressed is to put mildly and at the moment MHI is just another swear word. My number is 52824940 if you have anything further to advise and please note we have three other units by Mitsubishi previously installed. Max HERMAN

Hi Joseph,

Sorry to hear of the issues you're having. Are there any lights flashing on the unit when it experiences the fault? If you refer to the back of your user manual there are some troubleshooting steps which should help you identify what the fault may be.

If you could note which lights are flashing and then give us a call on 1300 138 007 one of technical team will be able to go through some troubleshooting with you.
