Mitsubishi Electric and Mitsubishi Heavy Industries aren't related

Mitsubishi Electric and Mitsubishi Heavy Industries (MHI) are two completely separate companies. Their Australian arms are separate Pty Ltd companies, and their Japanese parents are separately listed. Not parent and subsidiary. Not related. Different Australian Business Numbers (ABNs), different product families and different after-sales contacts. Mix them up and you get the wrong warranty contact and the wrong parts.

We've left the MHI after-sales number blank on purpose. We couldn't verify a published after-sales number for MHI's Australian company (MHIAA), and a plausible-looking number in that cell would be worse than a gap.

Why does it matter on a real job?

It goes wrong in four ways. The wrong warranty contact, the wrong parts, the wrong service agent, and the wrong spec on a quote.

None of those are abstract. Ringing Mitsubishi Electric about an MHI unit gets you nowhere slowly, and specifying an M series where the job was quoted on a Bronte is a different machine at a different price.

The trade already treats them as separate. Major wholesalers carry both as two distinct brands, with separate product pages and separate cassette and ducted ranges. So the mix-ups mostly happen on the customer side and in generic stuff online.

Do the warranty cards cover what you'd assume?

Not always. Mitsubishi Electric's card only covers the M, S and P series, and leaves out VRF. So a City Multi job isn't covered by the card you might have on file.

MHIAA keeps it short. The unit has to be installed by a licensed ARCtick installer, or the warranty is voided.

We couldn't find MHIAA's commercial warranty terms published anywhere. If you're quoting commercial MHI work, ask the distributor before you price the risk, not after.

Rethinking which brands you carry?

It's a bigger decision than the margin on the next job, because it decides who you ring when something goes wrong in year four.

Who this is for: small and medium HVAC contractors in Victoria. If you're a homeowner after a rebate or a repair, you need a licensed contractor, not us, and yours can point you the right way.
