When it’s springtime, you’re going to rely on heating and cooling for those unpredictable rainy/windy days in Melbourne! A multi-split air conditioner is an amazing pick for quick temperature changes (such as humidity highs and lows) throughout the day. But the best part? It heats multiple rooms instead of a single one.
If you’ve never bought a split system before, it can be overwhelming weighing up the different types, but the goal of this article is to make this easier.
Let’s check out the benefits of installing a multi head split system in your home or business building. We’ll talk about installation costs, energy efficiency, and why it’s so versatile throughout all seasons.

A split system has two parts: the condenser and the heat exchanger. The heat exchanger blows cool air into the room, and the condenser converts high-pressure gas into a liquid.
Featuring an outdoor unit (and multiple indoor units), a multi-head system cools/heats rooms simultaneously, and you only need to install one outdoor unit to do this.
How does this compare to a single split system? A single indoor unit is connected to an outdoor one, so the installation process isn’t as tricky, but a multi head has a lot more flexibility for heating and cooling capabilities.
In the rooms you’ve installed a multi-split (lounge room, study room or bedroom), the temperature is completely customisable for each space. Control, schedule, and set!
Some rooms will be warmer than others, and some might not have any heating or cooling when they’re not in use. Easily zone off rooms to conserve energy for more control over your environment. For example, while you’re at work, turn on the heater before you arrive home. It’s the perfect way to feel cosy on those cold nights or refreshed after a long day.
The Super Multi NX from Daikin offers:
A multi-split heats/cools areas of your space only when necessary, and you’ll save a lot more on energy costs with individually controlled, targeted cooling as you see fit.
Cut back on any energy consumption and stop wasting money on unused rooms. Multi-splits also have programmable fan speeds and thermostats. Overall, they’re a smart and sustainable choice for residential and commercial properties wanting the benefits of heating/cooling without a hefty energy bill.
The R32 refrigerant in Daikin models, for example, cuts back the Global Warming Factor, so it’s a lot more environmentally friendly.
Do you want a new air conditioner that doesn’t have tons of hurdles to set up? In comparison to a ducted system, a multi-split is easier to install as it doesn’t need extensive property renovations to install any ductwork.
All that needs to be done is a small hole has to be drilled in the wall to connect the indoor and outdoor units. If you have limited space, you’ll have the freedom to install it in a variety of ways due to its smaller size.

Sensitive to noise? Although there are more indoor units installed, surprisingly, they’re very quiet since there’s only one outdoor compressor (the loudest part of an AC).
When you compare them to traditional window units or central AC systems, a multi-split is a lot less disruptive. You’ll sleep a lot better during the night or nap during the day without distracting buzzing sounds.
The Mitsubishi PUMY-SP Series, for example, includes a Quiet Mode so sound levels are under 10 dB(A), so it’s a great option for apartments or townhouses. Quiet Mode is configured through the outdoor units control board so the system can run night-time hours or designated periods. It’s also a versatile design suitable for small to medium-sized homes and business spaces.
As well as keeping you cool or warm, a multi-split system removes allergens and pollutants from the air inside. Air filters trap pollen, dust and other airborne particles before they circulate.
Suffer from allergies or respiratory problems such as asthma? A multi-head AC also reduces the level of moisture in the air, preventing mildew or mould growth. Your home or business area will be healthier and more comfortable for everyone.
A multi-split option is also extremely versatile. Install different types for each of your spaces. For example, a quieter AC unit for your home office or a higher-capacity one for your lounge room.
From ceiling to cassette, bulkhead to floor standing, you’re not limited to one design.
The Mitsubishi PUMY-SP Series has over 27 indoor models with multiple capacities available. Its newer, more compact size fits into the narrow unit space of apartments or offices with a height of less than a metre.

How do you know if a multi-split is your best choice? If you need a whole-home solution but lack the roof space for ducted air conditioning or want to avoid complex ductwork installations, a multi-split is worth the investment!
But with that said, it might be less cost-effective for single rooms compared to single splits and may have higher maintenance costs.

The Super Multi NX (R32) offers multi-room air conditioning of up to 5 rooms! With a wide variety of indoor units available, it is easy to select a model that matches what you’re looking for.
The ideal temperature can be maintained, so running costs are kept low; only rooms requiring air conditioning are switched on.
The new Super Multi NX also features R32 refrigerant to deliver more efficient cooling and heating with less harm to the environment. Choose from bulkhead, wall-mounted, ducted and cassette designs.

Best for heating/cooling up to 14 rooms, small block sizes with limited outdoor space or larger properties, Daikin’s VRV IV-S incorporates the latest technology from VRV commercial air conditioners. Expect remarkable energy efficiency, quiet operations and long piping runs of up to 100m (24kW Model) for a flexible condenser placement.
The compact size and horizontal discharge design of the VRV IV-S outdoor unit make it an ideal solution for the modern home. Design options include bulkhead or ducted.
