Air & Water and Mitsubishi Heavy Industries
Air and Water are proud to be a specialist dealer of Mitsubishi Heavy Industries (MHI) air conditioners as we both believe in providing the best value for money with top quality reliable systems.
MHI has been voted Australia’s Best Brand for two years in a row.
For over 130 years MHI Air Conditioning has been making innovative quality reverse cycle air conditioners to heat and cool your home. As expected of a Japanese company with Japanese design and engineering, quality and efficiency is of utmost importance. That’s why their air conditioners amongst the most energy efficient on the market.
As a diversified multi-national company, MHI has the scale to keep manufacturing costs down so you benefit from great value for money. A triple win: superior quality, low running costs and a low purchase price combined with all the features you would expect from modern day air conditioners.
For peace of mind MHI offer a five year warranty on their domestic air conditioners and Air and Water provide a five year warranty on domestic installations.
So which MHI Air Conditioner is right for you?
If you already know what system or model air conditioner you need for your home or business, talk to us today to arrange a quote, or simply send us your house plans and we’ll work it all out for you and call you back.
If you’re not sure which Toshiba air conditioner you need, here’s a quick look at their range. All residential MHI air conditioners come with the DC Twin-rotary compressor and DC Hybrid Inverter, detailed below. To understand the types and price range of different systems read our Ultimate Guide to Air Conditioning.
This meant that when the compressor motor was operated at a low speed, especially when the room temperature was stable, the energy-saving capability was reduced. The PAM (Pulse Amplitude Modulation) inverter solved this problem by making it possible to control the compressor’s rotation across a wide range of speeds
MHI Split System Air Conditioners
MHI have three ranges of wall split (Hi-wall) – the Avanti, Avanti Plus and the Bronti. The Avanti is most popular in Perth as it is well priced without comprising on performance or quality. The Avanti Plus offers more efficient running and Clear Air Technology.
Both ranges include the Eco-logic setting which achieves up to 25% energy saving compared to the standard setting without sacrificing comfort by slowly adjusting the temperature setting to a more efficient level.
Air and Water also supplies and installs MHI’s four way cassettes and floor consoles.

MHI Multi-Split Air Conditioning System
MHI multi-split systems treat up to 5 rooms with either wall splits, cassettes, ducted fan coil unit, floor consoles or a combination of these indoor units. They come in an inverter and demand response enabled range.

MHI Ducted Reverse Cycle Air Conditioning System
MHI’s ducted air conditioners (FDUA models) can be zoned to reduce the area being treated, reducing the size of system required and running cost. The smaller 10 to 14kW models are single phase (FDUA100 to FDUA140) and larger 16 to 20 kW models are three phase.
MHI’s ducted systems beat others on the market for their heating (Coefficiency Of Performance) and cooling (Energy Efficiency Rating) rating. This efficiency translates to reduced running cost, making them very popular as they are also competitively priced.
MHI ducted air conditioners are compatible with the easy to use WiFi compatible iZone 4 series controller. The iZone comes with the very popular optional iSave system which drastically reduces your air conditioners running cost. Air & Water is the market leader in Perth for installing iZone and iSave and have been awarded by Air Stream and iZone.
MHI VRF Systems
Variable Refrigerant Flow (VRF) – also known as VRV- systems are suitable for mid size to large commercial buildings. MHI make a mini-VRF suitable for smaller scale developments as well as a VRF for large developments. The benefits of VRF technology include less piping and greater energy efficiency.
Inverter Technology in MHI Air Conditioners
Compressors, the outdoor unit which powers the air conditioner, are commonly fixed speed or variable speed (inverter). A fixed speed compressor runs at full capacity and stops when it exceeds the desired temperature and re-starts automatically when the actual temperature deviates from the desired temperature by a couple of degrees.
The disadvantage of this are noise and comparatively higher running costs. An inverter compressor varies its speed reducing noise, saving power and enabling a consistent temperature.
MHI was the first company to incorporate inverters in their air conditioners and 30+ years later they are still at the forefront of technology with their full range of residential models coming with DC twin-rotary compressor and DC hybrid inverter.

Their DC Twin-rotary compressor ensures accurate compressor rotation minimising noise and vibration – so the sound of the outdoor unit is hardly noticeable. This is a fantastic feature for modern homes where the outdoor unit is placed close to your neighbour’s boundary as you don’t want your neighbours complaining when you run your air conditioner. The twin rotary compressor also ensures power is used more effectively
MHI’s highly efficient compressor, combined with a Neodymium motor that uses powerful, rear earth magnets, MHI air conditioners can deliver a higher motor efficiency while producing much less operational noise. The PAM (Pulse Amplitude Modulation) control used in MHI air conditioners helps minimise the loss of electricity and boost the efficiency by allowing the unit to reach temperature quickly before slowing down the compressor. This provides the highest levels of power for when you need to get cool (or warm) fast, while PWM (Pulse Width Modulation) ensures the desired room temperature is maintained with optimum energy efficiency. Both these features explain why MHI has a higher energy rating than other leading brands.
To be kind to the environment, all inverter models run on R410A non-ozone depleting refrigerant. They also all come with a built in filter function that produces better airflow and improved air quality throughout the house.
There’s a huge range of options whichever type of air conditioner you decide is right for you, and MHI and Air and Water provide plenty of advanced features that will compliment your home as well as contribute to your household’s energy efficiency
