Split System and Multi Split Air Conditioning in Ballarat
A split system heats and cools a single room from one wall-mounted unit. A multi split runs several indoor units from a single outdoor unit, giving you room-by-room comfort through the house while keeping just one unit outside. Kingdom Climate Solutions installs split system and multi split air conditioning across Ballarat and Central Victoria. Every install is designed around your home, sized properly and finished cleanly.

How It Works
1
System Setup
A single, powerful outdoor unit is connected to multiple indoor units via refrigerant pipes.
2
Independent Room Control
Each indoor unit operates independently, allowing different temperature settings in different rooms or zones.
3
Heat Transfer
The outdoor unit circulates refrigerant to and from the indoor units, transferring heat as needed, either removing it for cooling or supplying it for heating.
4
Demand Management
The outdoor unit adjusts its performance to meet the combined heating or cooling demand of all active indoor units.
Pros
- Allows independent climate control for different rooms or zones.
- Saves outdoor space by requiring only a single outdoor unit.
- Energy-efficient, especially with modern inverter technology that adjusts output to demand.
- Customisable comfort for your family across multiple rooms.
- Versatile installation options for indoor units (wall, floor, ceiling).
- Potential eligibility for government rebates.
Cons
- Higher upfront cost compared to installing single split systems for each room.
- May be less effective than a ducted system for very large, open-plan areas.
- The indoor and outdoor units are visible, which may appear to be visually unappealing
- Condensate drains for indoor units need to be managed and can sometimes be visually unappealing.

Reverse Cycle Air Conditioning Function

Drawing in External Heat
Even in low temperatures, the external unit draws heat from the air outdoors.Heat Transfer Mechanism
The system compresses and expands the refrigerant, which helps move heat to the indoor unit.
Evenly Dispersing Warm Air Indoors
Heated air is distributed across the room by the indoor unit’s fan.

Air Extraction from Indoors
The indoor unit pulls warm air from the room.
Refrigerant-Based Heat Transfer
The refrigerant transfers the heat to the outdoor unit.
Expelling Heat Outside
The outdoor unit vents heat outside, letting cool air flow back into the room.
When a Split or Multi Split Suits Your Home
Split system installation is the right fit for single rooms, extensions, and homes without the roof space for ducting. A multi split takes it further, conditioning several rooms with independent control in each, so one bedroom can run cooler than the living room and unused rooms can be switched off.
For whole-home comfort where roof space allows, see our ducted reverse cycle systems. For a single room where the units can sit on the same wall, a back-to-back split system is the simplest install.
Reverse Cycle Heating and Cooling from One System
Every split and multi split system we install is a reverse cycle split system. It heats in winter, cools in summer and runs on electricity, which is why it is a common choice for households moving away from gas while keeping control room by room.
Modern inverter technology adjusts the system’s output to hold your set temperature efficiently, sized to the rooms it serves.
Frequently Asked Questions
What is the difference between a multi split and a back-to-back split system?
A back-to-back system runs one indoor unit from one outdoor unit and suits a single room. A multi split runs several indoor units from one outdoor unit, so you can condition several rooms while keeping just one unit outside.
How much does it cost to install a split system?
It depends on the number of indoor units, the brand and the run lengths in your home. We confirm the price after a free on-site assessment so there are no surprises.
How many rooms can one multi split system run?
Most systems connect three to six indoor units to a single outdoor unit, depending on the model and the capacity your home needs. We size this during the assessment.
Can a multi split replace gas heating?
Yes. A reverse cycle multi split heats and cools, so it is a common choice for households moving away from gas while keeping room-by-room control.
Do the indoor units run independently?
Yes. Each indoor unit has its own control, so different rooms can run at different temperatures, and unused rooms can be switched off.
