Commercial Multi-Split System Installation
When your business needs efficient air conditioning across multiple rooms or zones, a multi-split system is the ideal solution. Connecting one outdoor unit to several indoor units, multi-splits provide individual climate control for different areas without the need for multiple outdoor compressors.
At Thompson Cooling, we design and install multi-split systems for commercial properties across Brisbane and the Gold Coast. From office suites and medical practices to retail stores and cafés, we deliver tailored solutions that balance comfort, efficiency, and cost-effectiveness.
For smaller single-room solutions, see our Commercial Single Split Installation.
Why Choose a Multi-Split System for Your Business?
Multi-split systems are the perfect step up for businesses that need more flexibility than a single split system. They allow each indoor unit to be controlled independently, so you can customise comfort in different rooms or areas.
Advantages include:
- One outdoor unit servicing multiple indoor units
- Independent temperature control for each room
- Energy savings by only cooling or heating spaces in use
- Flexible installation with a range of indoor unit styles
- Space-saving solution compared to multiple single splits
For even larger buildings, explore our VRF/VRV Systems.
