Sunshine Coast Multi-Split Air Conditioning
If you want different temperatures in different rooms — without a wall full of outdoor units — multi-split air conditioning is the way to go. At Allchin Airconditioning & Refrigeration Electrical, we install and service multi-split systems across the Sunshine Coast from our Caloundra workshop.
These systems connect several indoor units to a single outdoor compressor, so you can cool (or heat) each room on its own schedule. They're ideal for homes, apartments or commercial spaces with limited exterior space. We work with leading brands like Daikin, Fujitsu and Panasonic, and we’ll help you pick the best layout for your space.
Whether it’s a new build, a retrofit or an upgrade, we’ll make sure the system is installed properly, zoned smartly and built to last. Give us a call on

Multi-Split Air Conditioning for Zoned Comfort
Multi-split air conditioning gives you all the flexibility of split systems — with none of the outdoor clutter. Each room can have its own unit and temperature setting, while everything runs off one outdoor system. We’ve installed these setups in family homes, rentals, offices and everything in between.
You can even mix and match indoor units — a wall mount in one room, a cassette in another, a slim console elsewhere. We’ll help you design a system that works for your layout, budget and lifestyle, and handle the electrical and zoning work at the same time.
We also handle servicing, breakdowns and upgrades for existing multi-split systems. If your airflow’s dropped off, your system’s noisy or you just want to add another room to your setup, we can make it happen — quickly and cleanly.
Frequently Asked Questions
How does a multi-split air conditioning system work?
A multi-split system uses one outdoor compressor to power several indoor air conditioning units. Each indoor unit can be set independently, so different rooms can have different temperatures at the same time.
This setup reduces outdoor clutter and works well in homes or offices where space is limited. The units are connected via refrigerant piping and wiring, and the system balances load so that energy is used efficiently across all connected units.
What are the benefits of multi-split air conditioning?
Multi-split systems save space, reduce noise and give you full control over each room’s temperature. You can cool or heat just the areas you're using, which can lower power bills.
They also keep the exterior of your home looking clean, with only one outdoor unit instead of several. For homes with family members who like different temperatures — or businesses with varying room sizes — they offer real flexibility.
Can I mix different types of indoor units?
Yes. One of the big advantages of multi-split systems is that you can mix and match. You might install a wall-mounted unit in the bedroom, a cassette in the lounge and a slimline console in the hallway — all connected to the same outdoor system.
This allows for smarter interior design choices while keeping all areas comfortable. The main requirement is ensuring all chosen units are compatible with the same outdoor model.
How many rooms can a multi-split system support?
Most systems can handle between two and five indoor units, though some high-capacity models go even higher. The number depends on the brand, model and the total capacity of the outdoor unit. It’s important not to overload the system — running too many indoor units at once can reduce performance.
A licensed technician will calculate the correct capacity based on room sizes, insulation and usage patterns.
