Corrosion Resistant Materials

Specially formulated layers assist in improving the durability of the aluminium section from harsh Australian weather.

Humidity Protections

The unit is covered by a protective coating on the circuit board to ensure longevity and durability.

Inverter Technology

A DC PAM control minimises electricity loss while boosting efficiency, allowing the unit to reach the preferred temperature quickly

Wide Operation Range

Units can operate in ambient outdoor temperatures as low as -20˚C in heating mode and as high as +46˚C in cooling mode, allowing for installation in areas where the weather can reach extremes.

Improved Heat Exchange

A uniquely designed heat exchange has been developed to improve refrigerant distribution and increase the effectiveness of the system.

Very quiet, powerful and effective

A few weeks ago, I substituted my noisy,40 DB on the quiet setting, Panasonic AC split system bedroom unit for a Mitsubishi unit. And wow what a difference. It is virtually silent (19db) when the fan is on the low setting and the unit is very powerful. I have quite a few AC units across several houses and I’m happy with the 9 Mitsubishi units, less happy with the Daikins and dislike and distrust the Panasonic units and their customer service.

Top of the line brand!

We have used plenty of MHI’s and many of our family and friends have done the same. Their after sales support is second to none. After reading some of the below reviews, it’s obvious people are using electricians to install air conditioners! We have only ever used qualified Refrigeration and Air Conditioning Tradesman, electricians aren’t licenced to service, repair or do warranty work on A/C’s anyway. Our installers tell us that a lot of problems with A/Cs come from a bad install anyway.

Great System

Has all the features I wanted, good quality and very well priced compared to similar units. The unit is very quiet and you hardly hear it running. The remote is easy to use and it cools the house quickly. Highly recommend this brand and comes with a 2 year factory warranty. I also received $100.00 cash back, which made the system even more affordable.
