    Multiple times I heard these are the best ACs. Better than Mitsubishi Electric. Build quality-wise to my understanding.

    Now debate, please, because I'm not an expert.

    • +3

      This guy raves on about them:

      https://airconditioningexpert.com.au/mitsubishi-air-conditio…

      He reckons he only got 5 warranty calls from 600 installs in 2020.

      All I can say is mine has been perfect, and I have recommended them to plenty of friends who also have had no problems. I also have a large Daikin that has been great, but they are a fair bit more expensive.

      • +3

        Had a laugh at the website. Like this particularly from the quote form.

        "I hope that covers all your questions. If not, feel free to give us a call during business hours.
        Business hours are 7am to 6pm Monday to Saturday. Unless you’re family*
        *In which case business hours are 1-2pm Tuesday"

      i have one MHI that is the better part of 10 years old.
      and just had an old daikin replaced with an MHI one.

      happy with both MHI units so far and now considering another 2 for the other bedrooms.

    • +2

      Great for residential installs. Dont think theyre any better than Daikin or Mitsubishi Electric. Any well known brand should last you at least 10 years without any issues.

    • +1

      I got a 3.5 kw split and a 14 kw ducted unit installed in the winter promo. My life is about 100 times better now. No matter the weather the house is pleasant and the running costs are low. They ramp up and down nicely to hold the temps and on my solar power graphs you can literally see the power falling off with the sun going down such that it follows the demand.

      Both units extremely quiet and probably overpowered for our situation but god has quality of life improved comoared to an old ducted unit that just sucked power, had many expensive controller failures and that just struggled to cool or heat well. New ducted unit has been on low for the whole year (about 2.5-3kW draw) because it's been milder than usual, but lots of room to move for when the world gets hotter.

      • Great field report, I enjoy hearing detailed real life experiences like yours. Glad to hear about your QOL improvement, and as you say the weather will only get hotter.

    • +3

      My understanding was a MHI was the best UNTIL 2020. From 2021 it seems ME is the one to choose.

      • Why?

    • I have heard this too. But I still think Panasonic are great.
      And both would be a heap better the Fujitsu.

    • I have 4 of them (and a panasonic) a few years ago they have been 100% trouble free.

      I did tons of reasearch before buying and these were regarded as among the best.

    • +3

      I've had 2 MHI for about 5 years, and they haven't missed a beat. I've installed another 2 MHIs just recently. I've also had 2 MEs for about 2 years and they haven't missed a beat. + 2 in my rental house for 5 years and didn’t miss a beat…but I’ve sold that house now, so can’t keep track.

      So I'll tell you in about another 5 years which is better… but that is a very small sample size… I’ve got two mates who are fridgies/leccies (both) and run their own businesses…one swears by MHI and only sells those, the other swears by ME/Daikin.

      I had a large Fuijitsu for about 20 years, and it didn't miss a beat and was still going….I just recently replaced it with the 2 MHIs mentioned above. However, I've also had a large Fujitsu installed 12 years ago break down 4 times (it appears there is an internal leak), and my brother had the same unit broke down once on him. I’ve got another Fujitsu bedroom unit that had a design flaw (need to install about 5m of pipework else it vibrates very loudly… I had to relocate it to another bedroom (my mate who installs MHIs had to relocate quite a few for people hence he knew what was wrong…he didn’t do the initial install. Fuijitsu are nowhere near as good as they used to be. And I’ve had another fujitsu die after about 6 years from geckos walking across the circuit boards. I’ve had a few installers (and sales people) state MHI covers their circuits boards better than other brands to prevent this (can't comment either way on MEs). We have a big problem with this in QLD. After the experience with the Fujitsu’s I will not be buying them again.

      Also had a Kelvinator and LG that came out of the same factory purchased about 2 years apart (exactly same except for the printing of the brand names on the units). The LG died after 15 years (fuijitsu was relocated to replace it), the kelvinator still going after 20. I had a carrier last 15 years (just replaced with an ME about 2 yrs ago). I have a panasonic that hasn’t missed a beat for 10 years in a spare room though so only used occasionally. My parents had a Hitachi box air con last 30 years… but they don’t make them like that anymore (replaced with an MHI split)

      I had 2 daikins fail after 8 years (compressor seized). So for the price, I won’t be buying them again…. I had a Mistral last 9 years… who would have thought a cheap mistral would outlast 2 Daikins??

      Pretty much every manufacturer now and then gets a ‘faulty batch’ due to a component failing before it should. Some manufacturers fail more than others as they constantly buy cheaper components to keep the price down, thus more likely a component will fail. Some brands have a component break under warranty and then once fixed, last 15/20 year. Others don’t break under warranty at all, but then die after 8 years… so which is better? Statistically, unless you are an installer who is doing the warranty repairs and replacements at end of life and then compare those figures with a different brand installer, then comments here are unlikely to definitively say which is better/more reliable…

      From now on I only install MHI or ME (whoever has cashback at the time), but that is because I will only do supply and install… too much buck passing when you buy at a retailer and then get someone else to install…absolutely not worth it for the few dollars you may save on the purchase… you can maybe avoid if you arrange the install through the same store, so If you are buying from bunnings or TGG, I suggest you arrange through them to install… supply and install saves so many headaches if there is ever a problem and more than makes up for any potential savings…

      • Great synopsis, and agree that Fujitsu are way overrated - too much money spent on marketing and not enough on quality.

        I’ve had a few installers (and sales people) state MHI covers their circuits boards better than other brands to prevent this

        Yep they coat them in resin to protect against corrosion and vermin.

      • For these aircons that lasted for a considerable amount of time, did you service them regularly? Especially Fujitsu one

        • Not really. I cleaned the inside unit, inc coils, every now and then, but never really touched the outdoor units.

          • @q9707418: Ya, I installed 4 MEs for my new build a year back and i get bombarded by installer's email and calls to get them serviced.

            I don't use them on daily basis, they hardly ran for quarter of time in the last year.

    • mine just broke down at 6 years old out of warranty… they're all garbage :P

      • take screenshots when you submit, Breville tried to jip me on the recent cashback, lucky I could prove it and they came good.

    • I got cashback for the first one I bought back in 2017. Took a while but I did eventually get it.

    • +1

      I submitted my form on the 6th and it was approved on the 8th. I also gotten my cashback in 2021 promotion.

    • I've got back all my claims over 3 separate periods (4 acs… 2 were in one claim). I think I had to contact them about one of the claims because the details were entered incorrectly in an invoice, but they paid them all. Took a few weeks sometimes, but paid them all.

  • This promo is only for wall mount split systems. I'm annoyed because I'm just about to get a larger ducted unit, and it's not eligible.

    • Yeah not as good as the winter promotion which included ducted systems. Maybe wait till winter if you can.

  • Is their Avanti split system units good? Looking for a small air con unit to suit a bedroom.

    • +2

      Excellent. My 2.5kW Avanti in the master bedroom has been solid for 5 years, and I just installed 2 x 2kW Avantis in the smaller bedrooms today.

      I have them running right now - completely quiet and quick cooling and they only use about 500W of power.

      • -1

        If they only use 500w of power then you have a COP of 5 which is not possible for an air cooled split unit.

        Either youre not getting the full 2.5kw cooling or more likely the unit is using more power of around 1kw.

        • +2

          I’m talking about the 2kW SRK20ZSA unit specifically, and they do actually have a COP of 4.8:

          https://mhiaa.com.au/document/split-systems-brochure/

          (Pg 19)

          Split systems have come a long way from the old COP 3.0 ratings - condensers are huge, compressors are efficient scroll type and refrigerants are better. I read an article recently that said splits with a COP of 6 are in development right now.

          I didn’t downvote you btw.

          • +1

            @Dogsrule: Youre not wrong but manufacturers always claim a higher COP because their testing conditions are very generous to produce a higher COP than reality.

            MHIAA test the units at 35C outdoor ambient and set the indoor unit temp to 27C to get such a high COP.
            In reality the outdoor temp would be 35-40C and the indoor temp would be set to 21-24C (most would just set it to 18C).

            In that scenario you run your unit at max capacity with a reduced COP of around 2-2.5. Not saying the Mitsubishi units are shit, this applies to all the brands. COP just changes based on the temperature difference between outside and inside. The best comparison unit to check is the IPLV values but i dont think MHIA give IPLV values for their units.

            *and I don't mind the downvotes I do this for a living.

            • @Obkay: Fair enough, I respect that view. I run mine at 24C and the outdoor units are shaded in the afternoon + I have wall and roof insulation. Outdoor temps around 35C and room temp at setpoint gives me about 500W of power draw measured at the power meter in my switchboard (everything else turned off).

              As you say, different conditions will give different results, no insulation, sun on the outdoor unit and bigger temp differentials will all increase power consumption and reduce COP.

      • Can you please share the installer details if you are in Melbourne. I don’t know a thing about how to go about getting them installed. Thank you

        • Sorry I’m in NSW.

        • I went through installation in Melbourne last year and got a few quotes

          Oz Air Group: ended up going with these guys and was very happy with them. Good reviews and they came up with the best positioning for my outdoor units. They have their own electricians too so they could give direct advice on my switchboard.

          OzWarm: great reviews too but they couldn't source the multi-unit I wanted. They outsource to an external electrician (which is still fine for most cases)

          NCG: cheapest quote, but a few more bad reviews.

      • How big are the rooms with a 2.0 kw system? Ive just been quoted $1900 supply and install for a Daikin Cora 2.5kw split AC ground level easy outside acces for a room of 3.9m x 3.7.

        I would have thought a 2.0kw system would be okay for that size room.

        Also…with this posted deal…where do i find a supply and installer that does everything plus get the Cashback?

        Brisbane QLD here

        • +1

          A 2kW system will handle that room size easily, my rooms are that size and the 2kW MHI from this deal works perfectly.

  • +2

    $100 cashback for the smaller units 2 to 5kw. These deals were only a bargain when coupled with ebay 20% off sales

  • +2

    I got their smallest reverse cycle 2 years ago.
    Installed and issues 2 weeks later. Seems like a fault from factory.

    Warranty was amazing came in a few days replaced the affected parts and has been running smoothly since

    Also remember for cashback you need the serial number on both internal and external units….so take a photo of the external unit number before you have it mounted up 2 stories. :-)

    Can't fault it
    Much better than my Panasonic 2kw in our room and on par with the massive 7.x kw daikan in the family area

    • How did you get them installed please?

      • +2

        Just call an electrician in your area to get them installed.

      • +2

        I used the yellow pages to find an installer but it was really hard to find an installer who will install units they haven't provided. I called about 20 companies before finding a guy. The AC installer mounted the units and did all plumbing and gased up the units. He then had electrician come out and wire them up. If I was to do it again I would buy the units from the installer or somewhere like Goodguys that have installers just because it's so much easier.

    • what issue was it?

  • +1

    Great aircon! Replaced and added 5 units in total in 2019 with cashback. Nil issues until now: Great for the price. Recommend it 100%

  • So these are only split… not ducted? Nothing for ducted?

    • +1

      Split only unfortunately. The winter promo included ducted.

  • So if we buy the units without install, any recommendations for getting them installed?

    Anything to watch out for? Any standard price (eg for standard tin roof one storey)?

    • Apparently Bunnings sell and install them. Although the install is obviously done by a local contractor.

    • +2

      A few years ago it was
      550 for back to back install.
      + $50/$100 for the outdoor unit to be off the ground and more if up on second story.
      + $60 per meter if not back to back

      Something like that.

      • +1

        My lil bro works for an AC installer and says closer to $700/800 now (VIC)

        • +1

          we just got quoted $3250 to install a 10kw condenser and 3 head units

          • @effraye: Central reverse cycle would be a hell of a lot more work than a back to back install I'd assume

  • +3

    Mitsubishi Heavy Industries are consistently the pick of the boffins on Whirlpool. One of their big advantages is parts are easy to get and anyone can service them. Have a look around over there though.
    https://forums.whirlpool.net.au/archive/2779182

    They're also Choice's best brand of air conditioner and have been for 5 years.
    https://mhiaa.com.au/choice-best-brand-airconditioner-five-y…

    We have a ducted system, it's been perfect for us so far. Quiet, heats and cools far better than expected, price wasn't horrid.

  • If you want to install let's say 5 split system air cons, do you need 5 new switches in the switchboard? Wondering if it's cheaper to get ducted for a 1 story house rather than 5 splits, considering the installation cost. Thanks

    • +1

      I think 5 splits will be more energy (and therefore power cost) efficient.

    • I’m assuming you’re referring to the isolator switches to the power switchboard?
      From what my aircon installer told me it’s only mandatory for split systems of 5kw+.
      I had both isolator switches installed for both my <5kw split system anyway, did cost a few hundred per isolator switch

      • +1

        I think they are talking about electrical circuits. Each outdoor unit requires an isolator switch mounted next to it regardless of size.

        • I recall a few years ago when I was thinking about installing air con, that a switch or a circuit (?) was needed in the switchboard and the cost of just getting one was close to $500 (Brisbane). I have space in the switchboard so I was quite surprised by the cost

          I haven't look at installing air con since then, but now I'm considering it again

          • @edforums: Depends on the size. Small 2-2.5kW units can often run off an existing power circuit that supplies power points already in that room, but bigger units will need their own circuit run. If you have a standard single story house with a roof cavity a new circuit should not cost anywhere near $500.

    • +2

      I would avoid ducts where you can. They can leak, are less efficient, gather dust so need cleaning which are harder to access.

      5 is a lot, so ensure they are sized correctly. Do you need one for every bedroom? Can you use ceiling fans to draw in AC air from other common areas for those hot/cold days? Use doors to zone areas.

      • I can use fans to draw air, sounds like a good idea but because of the shape of the house, will still need 4 at least

      • How do you clean ducts?

    • +1

      If they were smaller splits, you should be able to get away with 2 new circuits for all of them, if bigger units, 3 new circuits. I can guarantee that even if you needed a new circuit for each system, it would still be way cheaper to install 5 splits than a single ducted system.

      Ductwork is a lot harder to install than electrical circuits, can’t be installed in rooms without roof space, and ducted systems use way more power than splits:

      https://airconditioningexpert.com.au/ducted-air-conditioning

    • It won’t be cheaper.
      And duct uses more power as you can’t completely turn off rooms.

      • I thought that was possible via "zoning" or something like that

        • +1

          It has "minimum" outputs to prevent damage. So even if you turn off every zone, certain areas will still be forced on. The system cannot scale down.

        • It doesnt really work that way (as i found out… i assumed like you did).

        • Yeah the zoning only works so much. The minimum power output (and therefore input) of a ducted system is much higher than the minimum output of a small split.

          A split can keep a bedroom cool or warm with as little as a few hundred watts - a ducted system will probably use 4X that. Remember that all the ducts run through your hot or cold roof space as well - heaps of energy loss there too.

  • +1

    From my research it seemed like Mitsubishi Electric was better than Mitsubishi Heavy Industries now. Apparently the physical size of the internal unit is bigger with MHI as well which is important to know if space is limited

    • -1

      I think it’s the other way around - Mitsu Electric used to be better and are now worse. Their efficiency ratings are certainly worse.

      • +1

        Nope. The most recent reviews I read (can’t be bothered checking them now but they are in the recent deals in the last year or so) all said MHI was better but now ME is.

        • Interesting, I’ve read the opposite in many reviews, but everybody says they are still pretty similar. One thing is for sure - MHI have better published efficiency ratings than ME. Probably because of the larger evaporator in the larger indoor unit.

    • I came to the same conclusion last year and was open to both. Found a great price on a ME and bought it. Been great, gets lots of use.

    • +1

      I went with Mitsubishi Electric too after finding out the MHI only goes to 18 degrees for heating and not any lower. The indoor unit for the MHI was also bigger, i think same size for outdoor unit.

      • What's wrong with 18 degree heating anyway? With a relatively insulated house you can achieve that temp with minimal heating of anyform. If your body can tolerate temp below that level then any heating method is pretty much moot. A pair of track pants, fleece jumper and a pair of socks are all you need.

        • +1

          Our house (in inner Melbourne) gets to 10 degrees in winter, and lower if it's a real cold spell. Every insulation that can be done has been done.

          I'm sure there are places that get colder - but now everyone wants to run their air con at 8+ degrees warmer than the ambient temp. That's quite a lot of energy use

  • +4

    Fantastic! I just purchased the SRK50ZSA-W 5.0kW model yesterday. $150 cashback. I wouldn't have known about this without OzBargain. Thank you so much OP!

  • +8

    I have 5 avanti units ranging from 2.5kw to 8kw. Use them regularly for both heating and cooling and despite being v skeptical at the start, am loving them and their efficiency. I organised the install via bunnings and just a tip here for others keen on going down the same path. When drawing up the install quote with bunnings, go for the shortest metre run for pipes and cables possible, i.e say all my outdoor units are within two metres of my indoor units. Yes you have to pay the installer extra at the end(on the spot cash deal) but it saves bunnings taking quite a bit of a cut from you for every extra metre etc.

    • What were you skeptical about?

  • MHI aircons are great; but please be mindful about the indoor unit dimensions; for the high power, like 5kW or 7kW, it is huge. Some other great brands have smaller indoosr unit at the same power.

    • A physically smaller unit is going to be less efficient as the heat exchangers are smaller and require a greater temperature differential to achieve the same rate of heat transfer.

      Just look at the efficiently ratings and you will see the lower capacity units have more stars. As the capacity goes up the stars decrease until you get to the point in the range where it jumps to the bigger head unit.

      • Exactly right. Mitsu Electric has more compact indoor units than the equivalent Mitsu Heavy Industries, but their efficiency ratings are lower as well, likely for that very reason.

  • Can you buy it anywhere to get the cash back?

    On a separate there is no stock for Mitsubishi Avanti 2.5kw reverse split anywhere in Melbourne :-/

    • Yes you can buy anywhere. Check Bunnings, there is stock in Collingwood and probably others:

        very stupid question, does this come with the outdoor unit? cause the T&C of the cashback states exactly what indoor and outdoor combination should be…
