What Is a Split System Air Conditioner?
A split system air conditioner is one of the most popular types of home cooling. It includes two main components:
-
Indoor unit – mounts on a wall inside your room
-
Outdoor unit – sits outside the house
These are connected via copper pipes and electrical wiring. The split design helps it operate efficiently and quietly while cooling or heating individual rooms.
How Does a Split System Air Conditioner Work?
The system works by extracting warm air from your room, cooling it with refrigerant, and blowing cool air back inside. In reverse cycle models, it can also provide heating.
You may hear this referred to as a:
-
Split system air con
-
Split air conditioning unit
-
Reverse cycle split system
All of them mean essentially the same thing.
What Is Ducted Air Conditioning?
Ducted air conditioning is a central cooling (and heating) system installed in your roof space. It pushes air through a series of hidden ducts into each room of your house through discreet vents in the ceiling or wall.
Unlike split systems, ducted systems cool your entire home using a single unit.
How Does Ducted Air Conditioning Work?
Air is drawn into the central unit, cooled or heated, and then distributed evenly throughout the home. You can even set up zoned control, so you only cool specific rooms as needed.

| Feature | Split System Air Con | Ducted Air Conditioning |
|---|---|---|
| Installation Cost | Lower upfront cost | Higher initial investment |
| Energy Use | Efficient for single rooms | More efficient with zoning |
| Aesthetics | Visible indoor unit | Only vents are visible |
| Cooling Area | Single room or small zones | Whole-house coverage |
| Control | Individual remotes | Central touchscreen or smart app |
| Flexibility | Install as needed, room by room | Best for full-home installs |

FAQs: Split System Air Conditioning
1. What is a split system air conditioner?
A split system air conditioner uses an indoor and outdoor unit to cool or heat specific rooms. It’s energy-efficient, quiet, and perfect for individual spaces.
2. How does a split system air conditioner work?
It absorbs indoor heat and releases it outside via refrigerant coils. In reverse cycle models, it can also warm the room during winter.
3. Is a split system cheaper than ducted air con?
Yes. A split system has lower installation and operating costs for small areas. Ducted systems cost more but offer full-home coverage.
