Daikin vs Mitsubishi Electric Air Conditioning

Mac vs PC.  Melbourne vs Sydney.  Coke vs Pepsi.  These are certainly some the classic rivalries that just about everyone has an opinion on.

One such rivalry in the world of air conditioning is Daikin vs Mitsubishi Electric.  While this may not get everyone fired up, it is certain a hot topic for many air conditioning providers.

Mitsubishi and Daikin are two very recognizable brands that are always in demand.  They are rival companies selling much the same product and sharing a customer base.  Whether it be as a home air conditioner or commercial HVAC system, Daikin and Mitsubishi are found everywhere.

There are many factors to consider before installing an air conditioner.  Where considering installing a home ducted air conditioning system, or investigating whether ductless aircon may be best for your small business, there is much to consider.  Once type is decided, brand is often the next major decision.

Both Daikin and Mitsubishi Electric provide top quality, reliable, durable, and high-performance cooling and reverse cycle air conditioners.  However, there are some subtle differences between the brands that we will explore.  The differences can affect all stages, from installation, to air filtration, to repairs.

Air conditioning has many benefits, beyond what may first come to mind.  The differences between the different aircon brands may be subtle, but they can have significant impact on some of these benefits.

A small difference in one aspect may be the difference between being able to install an air conditioner or not.  It can also mean the difference between an aircon system that is just OK for your home or business versus one that is perfect for the space you need to heat or cool.

Brand Origins

Mitsubishi Air Conditioning Origin

It’s worth noting that the brand name Mitsubishi is actually only half the story, as it could refer to one of two different modern-day brands: Mitsubishi Electric or Mitsubishi Heavy Industries.  It is confusing as they both share the classic Mitsubishi three red diamond logo.  However, they are two completely separate companies and have been for a long time.

The origin of both Mitsubishi companies traces back to a Japanese company founded in 1870 called Mitsubishi Shipbuilding Co.  Nearly 50 years later, in 1921, Mitsubishi Shipbuilding Co diversified and created a range of new offset companies.  This included Mitsubishi Electric Corporation.  Interestingly, the name arose from the converted factory in Kobe that used to manufacture electric motors for ocean vessels.

For the past 100 years, Mitsubishi Electric and Mitsubishi Heavy Industries (MHI) have also been rivals.  In general, Mitsubishi Electric is considered a higher-quality product than MHI.  However, that is a whole other story for another day.

When talking about rivalry or comparison with Daikin, in general and indeed in this article, Mitsubishi Electric is the brand referred to.

Daikin Air Conditioning Origin

Daikin is another Japanese manufacturing company, founded in 1924 as Osaka Kinzoku Kogyosho LP.  In 1963 it was renamed Daikin Kogyo Co Ltd.  In 1982 it was renamed again to the current name, Daikin Industries Ltd.  Or Daikin, for short.

Unlike Mitsubishi, which manufactures a wide range of different products, Daikin was established with a sole focus on air conditioning.  It pays to know what air conditioning actually is to fully appreciate their focus.

Daikin specialises in researching, designing, developing, manufacturing, and distributing air conditioners worldwide.  As a result, they have led the industry with many valuable developments.

Outside of Japan, Daikin now has operations in Australia, America, Europe, Asia, India, African, and the Middle East.  While Daikin has expanded its focus from purely air conditioning units, their heart is air conditioner based.  The chemicals, equipment, and systems that they develop typically stem from or relate back to air conditioning.

Business Network

Industry Position and Innovation

As mentioned previously when discussing the origins of Mitsubishi and Daikin, Mitsubishi has been operating for longer than Daikin as a company in general.  However, Daikin is more purely focused on all things air conditioning.

Daikin Industry Position

Daikin is considered the industry leader for many reasons, including a large research and development team for one.  Valuable developments Daikin have been involved in include, but is not limited to:

  • Ongoing advances in chemical development, especially fluorochemicals,
  • Development of R32 refrigerant, a more environmentally-friendly aircon gas,
  • Invention of variable refrigerant volume (VRV) technology, which allows energy efficient simultaneous heating and cooling from units in the same system, and,
  • Invention of the world’s first split system with built-in humidification technology; the US7.

These are just some of the many valuable advancements that Daikin can claim.  There will no doubt be many more to come.

Mitsubishi Electric Industry Position

Mitsubishi as a broad company is involved in many different areas; tools, equipment, cars, shipbuilding, aviation, missiles, and even aerospace components.  However, the 1921 spin off –  Mitsubishi Electric, is focussed on household goods and electronics.

Mitsubishi Electric has been in the industry a few years longer than Daikin on the air conditioning side and has certainly cemented its place as being one of the best brands available.  Mitsubishi have developed a few features of their own, like Dual Barrier Coating and Quiet Mode.

However, Mitsubishi does tend to take its lead from Daikin.  Daikin technology has shown up in Mitsubishi Electric aircons, includes the use of R32 refrigerant in new AC units and Blue Fin anti-corrosion treatment on outdoor coils.  Mitsubishi also uses VRV technology under the name Variable Refrigerant Flow (VRF), as VRV is copyright to Daikin who invented it.


Split and Ducted System Range

Before we look at the brand differences, we need to know what units we are talking about as there are many different types of air conditioning unit.  In this article, we will focus mostly on individual split systems and split ducted systems used as home air conditioners or in light commercial application.

Split Systems, or Splits for short, typically refers to AC systems with wall, floor, and even under ceiling mounted indoor units (not to be confused with a cassette unit which is visibly mounted in the ceiling).  There is then a separate outdoor unit, connected by refrigerant pipework and interconnect cable.  Hence the term: split system, or splits.

Split Ducted Systems, or Ducted for short, also have an indoor and outdoor unit, but also have ductwork of some description or at least the indoor unit sitting in the ceiling space.  Air is then blown out into the room without the indoor unit being visible.  Ducted systems differ from other split system in this way.

The Daikin air conditioner split and ducted range covers all types of small and larger homes, providing a comfortable indoor environment in varied Australian climates.  Mitsubishi Electric also has a range of both split and ducted units to suit a wide range of home designs and spaces available.

Couple choosing air conditioning

Daikin Split System Air Conditioners

Daikin split system range currently consists of 8 main model types; US7 Series (FTXZ-N), Zena Series (FTXJ-T), Alira Series (FTXM-U/P), Cora Series (FTXV-U/L), Lite Series (FTXF-T), Project Series (FTXF-Q), Nexura (FVXG-K) Series, and Floor Standing Series (FTXS-R/L).

Daikin split cooling capacity ranges from 2.0kW up to 9.4kW.  However, not all series include all of the sizes.  You can find more information in the Daikin Split System Brochure, or the separate one for Daikin Lite Series.

The Zena Series is considered the most stylish of all the wall split systems.  Daikin Zena has an aesthetically pleasing compact, rectangular design.  It also comes with a choice of 2 colours; Black Wood or White Hair Line.

There are many other differences between Daikin wall split air conditioners.  It’s highly recommended to review the different series and find the best Daikin wall split air conditioner for you.

Mitsubishi Electric Split System Air Conditioners

Mitsubishi Electric split system range currently consists of 5 main models; MSZ-AP Series, MSZ-LN Series, MSZ-EF Series, MSY-GN Series (cool only), and MFZ-KJ Series (floor model).

Mitsubishi splits unit may be a home designer’s dream with multiple colour choices.  The MSZ-EF Series has the option of 3 different colours for the indoor unit across the range; Glossy Black, Matte Silver, and Classic White.  The range contains 4 system capacity options, up to 5.0kW.

The MSZ-LN Series is similar to the Daikin Zena in design; rectangular, stylish, and compact.  It comes with the option of Black, White or even Red!  Red may not be the most common or popular colour, but it’s certainly a great point of difference and option in the quality wall split system range.


Daikin Ducted Air Conditioners

The Daikin ducted air conditioning range currently consists of 4 main series: Daikin Inverter Ducted Series (FDYAN/FDYQN), Daikin Premium Inverter Ducted Series (FDYA/FDYQ), Slim-Line Ducted Series (FBA), and Bulkhead Ducted System Series (FDXS).  More information is available in the Daikin Ducted Systems Brochure.

Daikin ducted units have cooling ratings from 2.4kW to 24.0kW.  This means that there is likely to be a unit capacity available to suit your home.  If the house is double storey or particularly large, 2 (or more) systems can be installed.

Daikin Standard Inverter range comes with the option of single phase or three phase power for 6 common ducted sizes; 7.1kW, 8.5kW, 10kW, 12.5kW, 14kW and 15.5kW.  Unfortunately, Daikin removed such variation in power phase from their Premium range as of 2021.

It’s worth noting that Daikin units can ramp operations up and down to vary the cooling and heating capacity of the system.  With this in mind, the functional capacity range for Daikin Ducted units becomes 1.3kW to 27kW.

Ramping up is helpful to quickly cool down or heat up the indoor space.  This can also provide an added boost when the outdoor temperature is extreme (very hot or very cold).

Ramping down is helpful to reduce the amount of power required to operate the system, while still achieving suitable temperature control.  Ramping down also helps decrease energy usage and subsequent power bill, as it decreases the cost of running the air conditioning

Daikin Premium Inverters are better able to ramp up/down in response to demand compared to Daikin Standard Inverters.  This extends the higher end of the operational kW range of the premium systems.  This, along with some other technological advancements, results in a Premium Ducted System being ~10% more energy efficient than the same kW-rated Standard model.

Daikin’s slim-line range of ducted units are designed to fit into tight roof spaces.  The bulkhead units are also a compact option and the most discrete option available.  With only the controller, return air, and discharge grilles visible, these systems can fit in with just about any indoor décor.

Mitsubishi Electric Ducted Air Conditioners

Mitsubishi Electric ducted air conditioner range currently consists of 3 main series;

Mr Slim PEAD Series (PEAD-M-JAAD), Mr Slim PEA Series (PEA-M-GAA/WJA/HA), and SEZ Series Bulkhead (SEZ-KD-VAQ).  More information can be found in the Mitsubishi Electric Ducted Systems Brochure.

Mitsubishi ducted units have cooling ratings from 2.5kW up to 22kW.  Each unit comes with a capacity range, as do Daikin units.  That means that the system can operate at slightly higher and lower capacities.  With this in mind, the functional capacity range for Mitsubishi Electric ducted air conditioners becomes 1.4kW to 27kW.

Mitsubishi Electric offer several three phase options in the smaller ducted air con sizes, e.g. 10kW, 12.5kW and 14kW in the standard range.  The units have solid features across the ranges, such as PEAD-M-JAAD models that are designed to operate quietly both day and night.

Mitsubishi ducted units are designed for tight ceiling spaces.  Hence the range name; Mr Slim.  Mitsubishi indoor units tent to be smaller compared with Standard Daikin ducted units of the same capacity (kW rating).  This physical size difference can make or break a ducted install; some tight roof spaces may only fit a Mitsubishi unit when comparing standard ducted systems


Technology and Functionality

Like anything electronically based, technology has come along way.  Air conditioners are no different.  There is an incredible number of technological advancements and features backed into every single air conditioner unit in the Mitsubishi and Daikin range.

Daikin AC Technology

When it comes to air conditioning technology, there is no doubt that Daikin is the leader.  With a dedicated research and development team, Daikin strives to and successfully leads the way in all things air conditioning related.  Examples include chemical compounds, refrigerants, simultaneous heating/cooling, advanced fresh air, and humidification systems, just to name a few.

Daikin wall split systems come with a range of features.  Energy-saving Intelligent Eye, an array of smart timers, Coanda Airflow and draft prevention, plus an extensive list of advanced technology packed into compact size.  These are just some of the top features in various daikin split air conditioners across the range.

Daikin ducted air conditioners are also feature-packed.  With remarkable performance, energy efficiency, flexible duct design, and the ability to retrofit premium AC units to R22 pipework, they are just about as good as it gets for ducted air conditioning.

Daikin ducted units are compact for what they contain.  Next-level space saving comes in the form of bulkhead units.  Bulkhead units are the perfect choice to achieve a discreet install when ceiling space is limited.

With a bulkhead system, the indoor unit sits flush to the ceiling, with only the supply and return air grilles visible indoors.  This leaves plenty of space in a room for decorations, furniture, fixtures, and fittings.  They are also whisper quiet, so you’ll barely notice it’s there.

Mitsubishi Electric AC Technology

Mitsubishi Electric air conditioners are also feature-packed, helping to keep them up there with Daikin as an industry leader.  Many of their features are similar to the Daikin range, with a few tweaks to make them their own.  Some features are different, showing that Mitsubishi Electric can stand on its own as a leading air conditioner manufacturer.

Common features of Mitsubishi split systems, similar to Daikin splits, include Blue Fin Condenser treatment, advanced modes (i-Save, EconoCool, and Night modes), constant airflow patterns, and emergency and long operations.

New Mitsubishi Electric ducted air conditioners also now come with R32 refrigerant across the range.  They also come with flexible duct design and improved air flow due to high static pressure.  Certain Mitsubishi units can have up to 75m max pipe run.  Although it’s important to note that the longer the pipe run, the less efficient the system becomes.

Other points of difference include two-piece construction and two-way maintenance access for the PEA-M-HAA ducted range, for ease of installation, maintenance and repairs.  The PEA-M-GAA ducted range also offers computerised dehumidification.


AC Controls

Controls and Building Management Systems

From split system remotes, to wall controllers, to complete building management systems (BMS), Daikin and Mitsubishi offer high quality control with all of their products.  Their controllers have varying degrees of functionality.  Smart air conditioning controllers can have programmable schedules (day, week, and some even for a year) and zoning system integration.

Daikin Controllers

Daikin aircon remotes come in different shapes and sizes, from the Lite range up to the US7.  Precision control of 0.5 degree Celsius temperature adjustment and convenient On/Off timers both come standard.  Daikin remote controllers reflect all the features of a Daikin split system, but are also clear and easy to use.

Wi-Fi control for Daikin split systems comes as either standard or can be easily added, either during install or at a later date.  Hard-wired wall controllers can also be fitted to Daikin split air conditioners.  This is quite handy in offices and organisations where the remote controller is prone to going missing.

Daikin wall controllers come with a range of high-tech features.  Daikin control panels include lock systems and temperature limits to reduce energy waste.  As with ductless aircons, Daikin ducted controllers are easy to use and program with the Daikin Airbase App.

Daikin zone controller options include 4 zone or 8 zone control integration, including the BRC24Z4(8) and BRC230Z4(8) models. – Add Daikin zoning controller brochure to wordpress and add link to it here.  They can be stand alone for zone control or integrated to run both the Daikin aircon unit and zoning system.  Daikin zoning controls are one of, it not the most, popular air conditioner brands of zone controller on the market.

For Daikin large-scale commercial air conditioning controls, there is an extensive range of centralised controllers on offer to manage whole building HVAC systems.  Examples include the BACNet/LonWorks Interface, iTouch Manager Centralised Controller, and Individual Control Systems.

Daikin’s design and construct team can create almost unlimited combinations of units and controllers.  Systems can be designed specifically to a building layout and usage.  This allows Daikin units and controls to be tailored to just about any residential or commercial project you can imagine.  You just need a commercial air conditioning installation expert to attend, assess, and go from there.

Mitsubishi Electric Controllers

Mitsubishi aircon remotes also reflect the array of features offered with their ductless split systems.  Common timers include 24 hour and/or weekly settings.  Clear buttons and easy-to-use controls comes standard.

Mitsubishi Electric’s ducted wall controllers are also user friendly, with touch-button climate control.  Like Daikin, there are also zoning controllers available in the Mitsubishi range.  Similarly, Mitsubishi Wi-Fi either comes standard or can be easily added to an air conditioning system.

For Mitsubishi Electric commercial air conditioning controls, there is a wide range of controllers to suit business needs.  Mitsubishi offer 8 different controllers/interfaces, including interfaces with touch screens, and allow energy data filters to be uploaded.  With connection to up to 50 units, there is a controls set up to suit most buildings.

Mitsubishi Electric’s BMS and control systems can be controlled from a central point as individual area data can be managed via a browser.  Individual area climate control can be achieved by monitoring and responding to this live steam of data.  The Power PC Platform offered by Mitsubishi also supports the use of multiple power options.


AC installation points


Noise is an important factor to consider when looking to buy a new air conditioner.  Air conditioner units work hard, so they will obviously make some noise.  However, it is possible for this noise to be minimised in many ways; in the unit itself, installation, usage, maintenance, and repairs.

Noise levels are measured in decibels (dB).  Ambient noise in our everyday parks and suburbs is around 40 dB, while a whisper would be around 20 dB.  It is reasonable to expect new split air conditioners to be no louder than 40 dB, depending on kW rating.  For the outdoor unit, you wouldn’t want it to be more than 5 dB over the usual ambient noise, especially at night.

Daikin Air Conditioner Unit Noise

Daikin’s advanced technology has resulted in some of the quietest air conditioning units around.  Such technology includes Daikin split units includes Saw Edge indoor fan motor design, Advanced Cross Flow Fan with large diameter rotor and aerofoil blade design, specially designed Coanda Airflow discharge louvers, and condenser DC fan motor, just to name a few.

Daikin aircon sound levels are included in product specifications.  However, it can be confusing then there are multiple numbers involved.  There will be multiple lines referring to sound, as the indoor and outdoor aircon units have different sound levels.

In Daikin split system product specification tables, noise is typically reported as Sound Level (H/SL); H = on High fan, SL = Sounds Level.  The SL figure will be lower, and that is the figure you should look at when comparing to other brands to ensure you are comparing apples with apples.  Daikin wall split indoor units can run as low as 19dB in heating.  This is quieter than a whisper!

Mitsubishi Electric Air Conditioner Unit Noise

Mitsubishi’s advanced technology has resulted in some of the quietest air conditioning units around.  Such technology is often stems from or is very similar to Daikin, including specially designed indoor and outdoor fan motors, louvers and blades.

Noise reduction or quite mode in the Mitsubishi splits is a standout feature.  Noise during operation can drop to as low at 18dB for the MSZ-AP25 unit while heating.  This is quieter than a whisper and 1dB quieter than a comparable Daikin unit.  This makes them ideal as bedroom aircons.

Mitsubishi ducted units with Night Mode drops the decibel reading of the units while maintaining indoor comfort level.  The small drop in decibels actually makes a significant difference to the noise heard by occupants and neighbours.  Not only can occupants sleep better, but neighbours will be grateful too.

Mitsubishi Electric also promotes the fact that its units have high static pressure fans.  This helps improve airflow while noise is kept to a minimum.


Energy Efficiency

There is an increasing demand for energy efficient air conditioners that save money and the environment.  Most aircon brands have stepped up in response to this demand, especially Daikin and Mitsubishi Electric.

For more specific information, it’s recommended to look at the product specification for each air conditioning brand and compare the specific models you are considering.  Key figures to look at include EER/COP in cooling and heating plus star rating.  The greater the kW rating, the lower the efficiency by default, so be sure to compare the same kW rated units for accurate comparison.

Daikin Energy Efficient Air Conditioning

Daikin split systems have advanced technology that makes them some of the most energy efficient air conditioners in every range.  Advancements and additions to achieve this includes intelligent sensors, energy saving modes, greater surface area on heat exchanger coils, DC motors, aerodynamic blades, and new louver designs.

The standout has to be the Daikin US7, with the 2.5kW model achieving 7-star super efficiency rating according to the Australian Government Energy Ratings.  This system is packed full of other extras including humidification, fresh air mode, breeze simulation airflow, and advanced filtration system.  The price reflects this truly advanced wall split HVAC system.

Daikin ducted air conditioners also come with advanced technology to help the environment and your hip pocket.  Daikin premium ducted systems have better compressors and ability to ramp down, making them about 10% more energy efficient than standard ducted aircons.

All Daikin ducted systems exceed the Australian Government’s Minimum Energy Performance Standards (MEPS), which set out the minimum level of energy performance various products must have.  Furthermore, programmable temperature limits, lock-out system, Wi-Fi controls, and timers can be used to enhance the energy saving possible.

Mitsubishi Electric Energy Efficient Air Conditioning

Mitsubishi Electric also have an impressive range of energy efficiency aircon systems on offer.  The advanced technology they have adopted and incorporated into their air conditioners is to thank for this.  The use of more environmentally friendly refrigerants, DC motors, inverter technology, and quality motors are just some examples.  They also have some of their own features like wider and longer airflow patterns.

Mitsubishi Electric units also see energy savings through their brand-specific Econo Cool temperature control.  This feature involved the adjustment of airflow into a room depending on air outlet temperature.  It allows set temperatures to be raised by 2ºC without affecting room comfort, which in term providing a 20% gain in efficiency.

Mitsubishi ducted air conditioners also come with technology advancements the make them some of the most energy efficiency on the market.  Mitsubishi ducted aircons also exceed Minimum Energy Performance Standards (MEPS) and offer added saving through clever timers and Wi-Fi control.


ECO House

Air Filtration

Air filtration and purification is increasing in demand due to increased air pollution and a rise in allergies.  Air conditioning, in part, conditions the air that we breath indoors.

This means that air conditioning can improve the indoor air quality and helps prevent us from getting sick.  While this is valuable in homes, it is essential in a workplace.  However, it is dependent on routine aircon servicing, otherwise the reverse can occur.

Daikin Air Filtration

Daikin’s wall split systems and air purifiers are approved by the National Asthma Council Australia’s Sensitive Choice program.  The National Asthma Council recognises the advanced systems on offer from Daikin that help manage, reduce, or prevent common allergy triggers.

Common allergy triggers include pollens, dust mites, insects, pet dander/hair and mould.  Airflow, humidity, and air filtration all play a part in managing such allergens.  Allergic reactions can range from mild to life-threatening, so air conditioner assistance in allergy management is most certainly worthwhile.

Many of Daikin’s split systems contain advanced titanium air filters.  These filters trap microscopic particles, deactivate bacteria and viruses, decompose odour, and help to purify the air.

Daikin’s Dry Function helps via powerful humidity (moisture) removal to help prevent mould growth indoors.  This is why Daikin splits carry the blue butterfly symbol.

Mitsubishi Electric Air Filtration

Mitsubishi Electric may not have national recognition for their air filters, but it’s not to say they don’t have a high-quality filter system.  Mitsubishi have their own claim to cleaner air fame;  Plasma Duo Filter Systems.

Mitsubishi’s Plasma Duo Filter Systems uses a combination of technologies to achieve state of the art air purification and deodorisation.  The system consists of Plasma Air Purifying Filter combined with a Plasma Deodorising Filter.

The Plasma Air Purifying Filter removes substances like dust, dander, pollen, viruses, bacteria, etc.  Static electricity is used to catch the allergens and pollutants.  Negative ions then act to neutralise them.

The nanometre scale-meshed platinum catalyst deodorising filter works by trapping odour causing particles.  Such chemical particles include ammonia, hydrogen sulphide, trimethylamine, and methyl mercaptan.  Particles are then decomposed and eliminated by ozone generated from the plasma electrode.

After-Sales Service and Support

We often don’t stop to think about after-sales support when buying new products.  After all, there is so much to consider and research upfront, who has time to look at the complete lifecycle of a device?  However, it really does pay to stop and consider it for a moment, no matter what product or brand you are purchasing.

Daikin Air Conditioning Service

Daikin have a large fleet of air conditioner service and repair technicians available to attend to any Daikin aircon, new or old.  They are also known for having an extensive network of Daikin Warranty Agents in Brisbane, Australia, and World-Wide.

Daikin offer regular, intensive training to not only their own employees but also Daikin air conditioning contractors around the world.  For installation, service, repair, and other technical matters, Daikin have valuable training for the many different air conditioner types available.  Training is further broken down into aircon stage e.g. installation, diagnostic/repair, etc.

Daikin also offer a range of specialised diagnostic tools that help any Daikin expert test and service Daikin units with impressive speed and accuracy.  These tools are accompanied by high-level software for advanced comprehension and assist the AC tech in taking the correct actions.

Daikin also offer a service-friendly App; Daikin eQuip.  Any qualified air conditioning/refrigeration mechanic has access to the Daikin App with the use of their Refrigerant Handling Licence.   eQuip provides access to all the Tech data and information an air con contactor could need for productive work on modern-day Daikin air conditioners.

If more assistance or clarification is needed, Daikin also have a Tech Support Hotline for technicians to phone.  During the peak of summer, wait times can be high.  However, they offer a call back service to ensure technicians are not left holding on the phone for long periods of time.

If all that wasn’t enough, Daikin also offers a web-based Portal for Daikin Dealers to log into to access an extensive range of valuable information.  Engineering data, technical specifications, unit diagrams and images, just to name some of the useful documents readily available through the Daikin Portal.

Overall, Daikin are known for the highest level of support at all levels.  This can save a lot of time, money, energy, and frustration down the track as you look to maintain your new air conditioner throughout its complete lifespan.

Mitsubishi Electric Air Conditioning Service

Mitsubishi Electric also provide high-level support, but it’s hard to top Daikin’s next level service provision.  Mitsubishi have a network of warranty agents in Brisbane and around the world.

Mitsubishi Electric also offer training to Dealers and Agents, related to many of their different AC unit types.  Mitsubishi also have specialised diagnostic tools and software to assist with service and repairs when required.

Mitsubishi also have a Tech Support Hotline for technicians to phone if required while undertaking Mitsubishi aircon repairs.  They can also be contacted via email with reasonable response rate.  They also have a Technical Information portal for handy access to a range of useful documents.

Overall, Mitsubishi provide solid after-sales support.  Certainly far better than many other brands.  However, it’s hard to compare to Daikin who are an example how it can be done when you are solely focused on air conditioning.


AC Support

Aircon Repairs and Spare Parts

Daikin Aircon Repairs

As mentioned under After-Sales Support, Daikin have an extensive network of air con service and repair experts around the world.  They offer comprehensive brand-specific tools, software, phone application (Daikin eQuip), and web-based portal to support AC repairers in the field.  They also offer training to all their own technicians and Daikin Dealers, with phone support available when required.

Daikin also provide a range of handy How To videos online to help users service their new air conditioner units.   This helps maintain the aircon, extend its expected lifespan, and reduces the risk of breakdowns.  It can also help with some common call out issues, such as poor performance because of dirty filters or weird things happening with the Daikin wall controller.

When it comes to spare parts, Daikin service continues.  Their spare parts department is on par with the high-level service expected.  You can phone or email the spare parts team for assistance working out which part you need, price, and availability.  Daikin have also taken over other brands over the years, such as parts of McQuay, and can assist with spare parts for some of these aircon units too.

If you don’t want to email or call, you can instantly access interactive unit explosions and part lists online via Daikin’s Global Service Data Base (GSDB).  Any Daikin account holder can log in and search by different categories such as Model Number or Part Number to find what they need.  Information available includes part and possible substitute part number/s, price, number of that part in stock in NSW, just to name a few key pieces of information.  All data can be downloaded for reference later or parts can be ordered directly there and then.

Parts can also be ordered via email direct to the spare parts team.  Furthermore, Daikin Distribution Centres (DDC’s) are popping up around the country which also stock common spare parts to speed up repairs.  For example, if the part is in stock locally then you can expect fast air conditioning repair in Brisbane, Gold Coast, and everywhere in between with DDC’s in Geebung and Nerang.

If the part is not in stock and has to come from interstate, the parts are usually dispatched either same day or following day depending on when the order is placed.  During summer and peak times, it can take an extra few days to be dispatched, and even longer to arrive due to freight demand in the lead up to Christmas.  Airbags for small parts can see delivery within a matter of days and larger road freight items within a week.  Overall, it is much better than most if not all other air conditioning manufactures on the market.

Mitsubishi Electric Aircon Repairs

As mentioned under After-Sales Support, Mitsubishi Electric also have a network of specialists aircon service and repair technicians around the world.  Mitsubishi also offer comprehensive brand-specific tools, software, training, and dedicated phone number to assist aircon repairers out in the field.

Mitsubishi Electric make it a little more difficult than Daikin to obtain spare part details, including part number, price, and availability.  Typically, you need to provide an account number when obtaining part numbers and pricing over the phone.  There is no online login to quickly obtain part information unfortunately.

When ordering parts, you have to do it via email and include the serial number of the air conditioner unit being repaired.  This could be challenge/delay the process if the serial number was not recorded at the time of the initial breakdown/site visit.  Parts also take longer to arrive from interstate.

If there is an issue with a part number, a reply email is typically sent in response to the purchase order.  This can be missed with the volume of emails often received these days.  This is unlike Daikin for which it is not uncommon for them to phone you to clarify an order, rather than sending an email and delaying the parts dispatch process further.

Mitsubishi Electric do provide high-level breakdown/repairs support, but it’s hard to top Daikin in this area.   Their staff are spread across all categories of product, from air

conditioners units to aerospace components.

Daikin Air Conditioning Technician


Companies and individual air conditioning contractors can be bias to whichever brand they primarily sell.  However, good AC companies should sell, install, service, and repair both brands.

It’s good practice to quote both brand options for new installs where suitable and allow individuals the opportunity to decide.  However, when working with customers and discussing requirements, one option may be more suitable than another and quoted accordingly.

Mitsubishi Electric are no doubt a high-quality air conditioner manufacturer, with a league of loyal customers.  They have received industry certification and expert endorsements.  Mitsubishi has a range of compact, stylish, quiet, and high-tech air conditioning systems to suit many homes and businesses.

Daikin also has an extensive range of air conditioner units to suit just about any residential or commercial HVAC requirements.  If they don’t have it, they can typically design and construct it to suit.  Overall, Daikin tends to come out on top with their innovation, technology, product range, reliability, and after-sales service.  They have won many industry awards and continue to excel with their air conditioning focused approached.

At the end of the day, the great Mitsubishi Electric vs Daikin air conditioning debate largely comes down to personal preference.  There are some minor differences between the brands and their products which may be the deciding factor, depending on your specific aircon requirements.  However, both brands offer excellent value for money, provided you buy from a Mitsubishi or Daikin Dealer.

If you have any questions about with brand, or need help deciding which AC brand is best for you, it is recommended to reach out to an experienced air conditioning company that can provide both Daikin and Mitsubishi options.  That way, they can answer any questions you may have about either brand and give you pricing options on both!
