Costs vary depending on property complexity, ductwork requirements, and optional features.

3. Single Split Systems

• Ideal for small flats or individual rooms.

• Hidden ductwork delivers cool or warm air to multiple rooms.
• Ideal for high-end homes or commercial properties.

• Installation is more involved, often taking several days.

Ducted systems provide whole-building comfort, enhancing property value while remaining discreet.

6. VRF / VRV Systems

• Variable Refrigerant Flow or Volume systems.

• Highly energy-efficient with zoned control capabilities.
• Installation requires experienced engineers and longer project timelines.

VRF/VRV systems are the premium solution for complex commercial buildings and large-scale residential properties.

7. Additional Cost Considerations

Even with a base system selected, additional factors may influence the final cost:

• Electrical Upgrades - Older properties may need rewiring or new circuits.
• Ceiling or Floor Modifications - For ducted systems, some building work may be required.
• Smart Controls & Apps - Wi-Fi-enabled thermostats and automation.
• Maintenance Contracts - Optional service plans to extend system life.
• Energy Efficiency Incentives - High-efficiency units may qualify for lower running costs.

Discuss these options with your installer for a clear understanding of total investment.
