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 :)

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!

Quiet and easy installation. Good guys arranged it all. I chose big one cos I thought I'd never have to upgrade or be hot again. Probably bought too big it's a powerful machine. Easy to use, simple instructions. Temp control. Has whizz bang features I like the cold house one the best!

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

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.

Excellent since new


Bought 7.1kw split system in October 2014. Never had a problem. I don't understand some people complaining about it. I keep the filters clean and the installation was perfect. Cools great in summer and warms well in winter. The self cleaning mode is great. It's also Geco proof. This a/c has served me well and in its 3rd year without a hassle. I've owned Panasonic previously and replaced it after 7 years. Mitsubishi Heavy industries make industrial sized air conditioners and ranked first on this area. They've been around for over 70 years, and they know how to make a/c. The one I have is the Hyperinverter and it saves electricity. Very economical to run.

Highly recommended!


A great unit especially for heating, but works very well for cooling too. We have less need for the cooling in Ballarat but find it is very effective when needed. We had good advice about installation and made sure the outside unit was elevated as a previous unit used to freeze up when below zero. Make sure you get the right installer - we did!

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/.

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.

Hi Anna,

I'm sorry to hear of the issues you've had with your unit. Provided it is on the correct cooling setting, it should be delivering cold air. If it is brand new, I suggest speaking to the installer.

Please let me know if the issue wasn't rectified.
