There are two Mitsubishis, and it matters
Mitsubishi air conditioners come from two separate companies, and that is the single most important thing to know before you compare Mitsubishi quotes.
There are two separate companies selling air conditioners in Australia under the Mitsubishi name:
- Mitsubishi Electric
- Mitsubishi Heavy Industries, usually shortened to MHI
They share a name and a similar three-diamond logo because of common historical roots, but today they are independent companies and direct competitors in split systems and commercial VRF. Their products, warranties, dealer networks, prices and independent ratings are all different.
If two of your quotes say “Mitsubishi”, they may not be the same brand at all. Ask for the model number, not just the badge.
Quick way to tell them apart on a quote:
- Mitsubishi Electric model numbers usually start with MSZ (wall-mounted splits) or PEA (ducted)
- Mitsubishi Heavy Industries model numbers usually start with SRK, DXK or FDUA, and the ranges are named Bronte, Avanti and Ciara

The short version
Mitsubishi Heavy Industries has the stronger public independent result. It states that CHOICE named it Australia’s best air conditioner brand for 2026 (MHI’s announcement). On efficiency the two are close: on the Government’s energy register their best bedroom-size splits rate 5 and 5.5 stars for cooling.
Mitsubishi Electric’s strength is breadth It offers more indoor unit styles, which matters if you need a floor console, a cassette or a specific ducted configuration. On warranty there is nothing between them: both give 5 years parts and labour on residential systems.
Neither is a bad choice. Both are established brands with national service networks.
Which should you choose?
Choose MHI if:
- You want the brand with the best current independent record
- You are conditioning a large or long open-plan area, where the Bronte range’s long-throw airflow helps
- You need a very small capacity. The Ciara range starts at 1.5kW
- Owner reviews carry weight with you

Choose Mitsubishi Electric if:
- You need a specific indoor unit style that MHI does not offer
- Your installer knows the brand well and stands behind it
What matters more than which Mitsubishi
Both brands sit at the premium end. Before you agonise over the choice, make sure the basics are right, because they will affect your outcome more:
- The capacity is correct, based on a heat load assessment, not floor area. Our sizing guide
- You have checked the installer’s licences. How to check
- You have comparable quotes to weigh up. The same model can vary by hundreds of dollars between installers
A reminder about installation only a licensed technician can install an air conditioning system. Anyone installing or servicing a refrigerated air conditioner needs a Refrigerant Handling Licence from the Australian Refrigeration Council. Handling refrigerant without one is an offence. You can check any installer’s licence on the national register at lookforthetick.com.au. Our guide to choosing a reliable installer covers what else to check.
