Midea
Midea might not be as much of a household name in Australia as Rinnai, but globally, it’s massive. Midea is one of the world’s largest air conditioning manufacturers, supplying systems to over 200 countries. Their systems are especially popular with homeowners who want smart, energy-efficient tech at a lower price point.
They’ve gained traction in the VEU program too — offering models that are both affordable and rebate-eligible, making them a solid pick for budget-conscious Victorians.
Popular in Victoria for: Apartments, small to medium homes and anyone prioritising upfront savings without compromising on tech.
Both Rinnai and Midea offer VEU-eligible systems that work well in Victorian homes. Here's a closer look at what they bring to the table.
✅ 1. Reverse Cycle Split Systems
These are wall-mounted units that handle both cooling in summer and heating in winter — a must-have for Victoria’s unpredictable weather.
Rinnai offers the J Series and T Series, available from 2.5kW to 8.0kW. These models are known for their quiet operation, Wi-Fi control and high efficiency.
Midea rolls out options like the GAIA, EOS, Xtreme and Venus Series, ranging from 2.6kW to 8.0kW. Their systems are also Wi-Fi ready, sleek in design and known for faster temperature response.
✅ 2. Multi-Split Systems
Multi-split air conditioners let you connect 2–6 indoor units to one outdoor compressor, which means less space outside and individual control in each room. In fact VRF multi-split systems let you connect up to 12 indoor units. Hence, this system works well for large commercial spaces. However, you cannot go above the capacity of the outdoor unit when connecting indoor unites.
Anyway, when it comes to cooling or heating multiple rooms efficiently, multi-split systems are a smart pick—and both Midea and Rinnai offer great options.
Midea has two standout models: MULMI0513B and MULMI0618B. These are designed for Aussie homes that face both scorching summers and chilly winters. They’re highly energy-efficient, offer fast heating and cooling and come with extended warranties. With inverter tech and built-in Wi-Fi, they balance performance and affordability, making them ideal for families looking for long-term comfort and savings.

Rinnai also has excellent multi-split systems like the MON6H18B (ideal for up to six rooms) and MON5H13B (suited for five rooms). These models are great for larger households, offering strong performance while keeping indoor spaces comfortable and quiet. Rinnai’s systems are reliable, energy-efficient and perfect for families who want more control over the temperature in different rooms.
✅ 3. Ducted Reverse Cycle Systems
If you want climate control for the entire home with minimal visual clutter, ducted systems are the way to go.
Rinnai’s D Series is a favourite for full-house temperature control. It comes with zone control and impressive star ratings.
Midea also offers ducted options that are budget-friendly, quiet and packed with inverter features — great for families wanting to upgrade without breaking the bank.
Both Rinnai and Midea offer energy-efficient air conditioners with lower energy consumption which leads to lower power bills. And the best part is that both the brands have models that are eligible for the Victorian Energy Upgrade rebate. Yay! This means that upon switching to these VEU-approved models, you get a significant discount. So, your overall cost of getting a new air conditioner drops and you continue saving on energy bills month after month.
Now, if you’re trying to figure out which one performs better, keep an eye on two key things:
✅ Star ratings – for both cooling and heating
✅ COP (Coefficient of Performance) and EER (Energy Efficiency Ratio) – These tell you how efficiently the system turns electricity into heating or cooling.
For example:
- Midea’s Multi-split model has an EER rating of up to 3.94 and a COP rating of up to 4.62.
- Rinnai’s reverse cycle ducted systems have an average COP rating of 3.71 and an average EER rating of 3.35, making them highly efficient for both heating and cooling large spaces. These values reflect consistent energy performance across all models
So, no matter which way you lean — both brands help you save in the long run.

But there are a few important differences that can help you make the right call based on your needs, budget and long-term goals.
