Midea vs Rinnai: Which Air Conditioning System Is Right for Your Home?
And why these two brands are dominating the rebate scene in Victoria
Why You Keep Hearing About Midea and Rinnai
If you’re looking to install air conditioning in multiple rooms in Victoria, you’ve probably come across Midea and Rinnai as the top options. You might be wondering:
“Why these two? What makes them special?”
Here’s the answer: they’re energy-efficient, approved under the Victorian Energy Upgrades (VEU) program, and they generate more VEECs – which means you get more air conditioning rebates in Victoria and pay less overall.
So if you’re looking to keep your home comfortable and your costs low, these brands are at the top of the list for good reason.
What’s a Multi-Split System?
A multi-split air conditioning system is a clever setup that lets you heat or cool multiple rooms (up to six) using just one outdoor unit. It saves space, reduces clutter, and gives you the freedom to control the temperature in each room individually.
Ideal for:
● Families with different comfort preferences in each room
● Renovators replacing old gas systems
● Homes with limited outdoor space

How Rebates Factor In
Because both systems are approved under the Victorian Energy Upgrades (VEU) scheme, they qualify for government rebates on air conditioning.
However, Midea often generates more VEECs due to its higher efficiency ratings. That means your rebate could be larger, which lowers your upfront cost even more.
This is especially important for households replacing old gas heaters or outdated electric systems – the more efficient your upgrade, the more support you get.
