Best Mitsubishi Heavy Industries Air-Conditioners Air Conditioners

About three years ago NCG Air ( as Victorian Energy upgrades accredited installer ) and Mitsubishi Heavy industries ( Japanese quality!) came highly… Read more

recommended to me by a friend I decided to get a quote and apart from a great price I found their service was second to none. Alice , Kingsley and Pauline were fantastic in the admin area and did not miss a beat pleasant , courteous and expedient. Pauline was very sensitive to my request for an early install (as winter without heat was unbearable ) and to my surprise she was able to get the installation done within three days !!!

On the fitting side, Kenny and his young apprentice were equally pleasant and dynamic. They came, drilled holes , laid pipes etc whilst minimising mess . After the install, they cleaned up after themselves , tested the equipment and were out on their way to their next job. I have had 4 Brontë series fitted by NCG to date and I am very satisfied with their service and reliability of the units. I will continue to recommend both NCG and Mitsubishi heavy industries. Great job guys keep breaking those barriers! Thank you Con and family

I read reviews here and all those people who said it was so quiet never mentioned how operational noise is really bad. Got the 6kW Avanti and as… Read more

pointed out by another reviewer here it is the nosiest a/c I have ever experienced. When it just ticks along it is quiet but when it needs to do an operation the noise is just ridiculous. How could MHI not notice the louvre motors and high speed fan noise is pretty strange. Also no backlit remote control, even a cheap TCL has this and more. So disappointed with this purchase. Another reviewer mentioned a newer motherboard addresses some of this so I might contact MHI. I am about o buy another 6kW ac for another room but it might be Mitsubishi electric this time and seems to be the one to get.

Severe internal corrosion after only approximately six years – extremely disappointing Mitsubishi Heavy Industries response I purchased a Mitsubishi… Read more

Heavy Industries split-system air conditioner, model SRK50ZSXA-W, manufactured in 2018 and purchased and professionally installed in July 2020.

The unit has been properly maintained throughout its life.

Recently, during a major professional cleaning service, the indoor unit was opened and significant and advanced corrosion was discovered inside, including corrosion affecting the evaporator coil and surrounding metal components.

Importantly, the photographs showing the corrosion were taken BEFORE the major cleaning was carried out. The photographs clearly document the condition of the unit before any cleaning products were used during that service.

This is important because Mitsubishi Heavy Industries subsequently suggested that the corrosion may have been caused by cleaning chemicals that were not completely rinsed off.

I find that explanation extremely difficult to accept.

The corrosion was already clearly present and extensively advanced before the major cleaning. The photographs were taken before the cleaning, so the cleaning obviously could not have created the corrosion shown in those photographs.

The condition of the internal components was shocking for an air conditioner that was only approximately six years into its service life.

I contacted Mitsubishi Heavy Industries and provided photographs of the corrosion, expecting the manufacturer to take the matter seriously and investigate why such severe corrosion had developed inside the unit.

Instead, the response from the Regional Service Manager was that the factory had advised that this type of surface corrosion is commonly the result of cleaning solutions that have not been completely rinsed off, and that the corrosion on the screws could possibly indicate this had occurred.

In my opinion, this explanation is simply not convincing when you look at the actual condition of the unit and, most importantly, the timing of the photographs.

The photographs showing the corrosion were taken before the major cleaning.

So blaming a cleaning product for corrosion that was already clearly visible and extensively developed before that cleaning makes very little sense.

The corrosion is not a couple of small surface marks or a few slightly rusty screws. The level of deterioration is substantial and advanced.

That is why I expected Mitsubishi Heavy Industries to properly investigate the underlying cause rather than provide what I consider to be a convenient possible explanation and effectively point the finger at the cleaning process.

If Mitsubishi Heavy Industries believes cleaning chemicals caused this corrosion, then I believe it should be able to provide actual technical evidence demonstrating that this was the cause in my unit.

Instead, I was essentially told that it could possibly have happened and that I should ask the company carrying out the cleaning whether they had rinsed the chemicals properly.

That is not what I would consider a proper investigation by the manufacturer.

The evaporator coil and surrounding components are designed to operate in a cold and humid environment as part of normal air-conditioner operation. A customer should reasonably expect the materials, coatings and corrosion protection used inside the unit to be suitable for those conditions and to provide reasonable durability.

The extent and advancement of this corrosion raises legitimate questions about the materials, corrosion protection, manufacturing quality and expected service life of these components.

Mitsubishi Heavy Industries also indicated that they did not believe the corrosion would affect the system’s performance or operation.

Again, this completely misses the point.

The fact that an air conditioner may still operate does not explain why there is such severe internal corrosion after approximately six years, whether the corrosion will continue to progress, whether it could eventually affect the system, or whether the affected components will have a reasonable service life.

I challenged the explanation and raised my concerns with Mitsubishi Heavy Industries.

Unfortunately, rather than properly addressing those concerns and investigating the matter further, my complaint was effectively ignored.

That is what has disappointed me most.

I am not expecting a manufacturer to automatically accept every warranty claim. I am expecting a manufacturer to properly investigate a serious product issue and provide a technically credible explanation based on the evidence.

In this case, the evidence includes photographs showing the corrosion before the major cleaning took place.

For me, the response blaming or potentially blaming cleaning chemicals was therefore particularly disappointing.

I have deliberately not named the individual involved. My concern is with the Regional Service Manager’s handling of the complaint in that professional role, not with making this personal.

I purchased Mitsubishi Heavy Industries because I believed I was buying a quality and reliable product from an established manufacturer.

Unfortunately, when a serious problem appeared, my experience has been that the manufacturer was more interested in providing a possible reason why it was not responsible than properly investigating why this level of corrosion had developed.

Severe and advanced corrosion after approximately six years is not what I expected from a Mitsubishi Heavy Industries air conditioner. And the explanation I received afterwards was, in my view, completely inadequate.

What has made the situation even worse is the lack of meaningful follow-up after I challenged that explanation.

A product can fail. What matters is how the manufacturer deals with the customer when it happens.

In my case, the product has developed serious internal corrosion and the subsequent customer service has left me extremely disappointed.

This experience has seriously damaged my confidence in Mitsubishi Heavy Industries, and I would think very carefully before purchasing another MHI air conditioner.

I bought the 3.3kW Mitsubishi Ciara DXK12ZTLA-WF air conditioner to cool a single room, and it does the job very well. It is incredibly quiet… Read more

compared to the ancient 2.4kW Mitsubishi unit I had before.

I recommend buying an air conditioner with a little more cooling capacity than the minimum recommended for your room size. My old unit struggled to cool the room, whereas the Ciara cools it with ease.

There are plenty of options to customise the climate control to your preference. However, the instruction manual for the remote control is absolutely useless. It is far too technical and goes right over your head, hitting the wall behind you. The task of writing the manual should have been given to a high school student who has a Ciara at home. I had to search online to learn how to operate it, picking up useful bits and pieces of information from various sources.

Another issue with Mitsubishi, as with many air conditioner manufacturers, is that you may be supplied with a remote control that does not match the user manual. Fortunately, I received the correct RLH502A001 remote.

I rated the unit five stars because no product is perfect, and the Mitsubishi Ciara 3.3kW air conditioner comes very close. I put the poor instruction manual down to bad management. It is amazing how many managers are in positions of responsibility yet still do not understand what customers actually want. A simple chart showing what the little icons on the remote's screen mean would have been useful. Spreading the icons throughout the page text and diagrams in no apparent logical order turned the process into a paper chase.

lounge room. The unit has now failed with a 6 flash fault, which is either power or PCB board fault. Pretty disappointed as the unit is just over 5 years old. Was really expecting at least a 10 year life from these.

VERY QUICK AND PROFESSIONAL ! very impressed with the service provided.

Very responsive and good to work with. Prompt and organised. Show details

15.2kW ducted aircon – Had a slight hiccup at first but it was resolved and the unit works great. Show details

Great – super quite, needed to add streamers to outlets to know it was running Show details

Our house has never been the same – We live in an older house which has un-insulated walls. The 7kW aircon we had would slog it's guts out all summer and barely cool the house down.… Read more

Once we extended the house we had to move this aircon so our electrician suggested the ceiling cassette Mitsubishi at 10kW. This was a little overkill for what we needed but my goodness! The house is cool through Summer & warm as toast when we need it. I love it!
