Choosing the right air conditioning system can make all the difference to your comfort and energy bills – especially in the warm, coastal climate of the Gold Coast. If you’re renovating or building a new home, the big question often comes down to this: Central vs Split systems – which one truly fits your lifestyle?

Let’s break it down with insights from over 38 years of hands-on experience at DEEPCHILL, a trusted air conditioning contractor on the Gold Coast.
What is a Central air conditioning system?
Central air conditioning, also known as a ducted or multi-split system, uses one outdoor unit to power multiple indoor units throughout the home. Often used in large homes, villas, or commercial properties, a central system offers seamless temperature control through hidden ducts or ceiling cassettes.
Key Features:
- Single outdoor unit powering up to 60 indoor units
- Energy efficiency through inverter technology that adjusts power output
- Flexible indoor unit options: wall-mounted, ceiling cassettes, or concealed ducts
- Quiet and aesthetic with minimal visible indoor components
Central systems are perfect for homes over 100m², or homeowners looking for whole-home cooling with advanced controls and a polished interior look.

What is a Split system?
Split systems are the most common choice for smaller homes, single rooms, or when budget is a key factor. These units consist of one indoor unit paired with one outdoor condenser.
There are two types:
- Single-unit split systems: One indoor and one outdoor unit
- Multi-split systems: One outdoor unit supporting up to 5 indoor units
Key Features:
- Affordable upfront cost
- Quick installation
- Ideal for room-by-room control
- Basic cooling features without complex integration
While split systems are great for targeted cooling, they’re less suited for larger homes or households looking for streamlined design.
