The three main types of air con controllers in Australia and which type is 'best'?
5 December, 2025
Key Takeaway
Most Australian homes still use control systems designed decades ago, which is why comfort and efficiency often fall short. There are three main types of controllers: basic zone push buttons, integrated controllers and smart controllers. Each offers a very different level of comfort, accuracy and energy efficiency.
1. Basic zone push button systems
These systems are the oldest and most common type in Australia. Many installers still use them because they are inexpensive and familiar.
What they are
• Simple push buttons on a wall
• Usually control only two zones
• Airflow is either fully on or fully off
• No individual room control
• No sensors inside the rooms
Why they exist
Around 30 to 60 percent of Australian homes use this system because it has changed very little since the 70s. It is cheap, simple and requires almost no configuration.
Where they fall short
• You cool or heat large areas you are not using
• Hot and cold spots are common
• No temperature visibility for each room
• Almost no way to fine tune comfort
• Inefficient for larger or modern homes
This system works, but only at the most basic level.
2. Integrated controllers
This is the next step up and makes up roughly 30 to 40 percent of the market.
What they are
• A single wall mounted controller that manages both the air con unit and zones
• Often allows 4 to 8 zones
• Most don't offer airflow adjustments
• Slightly more flexible than push button systems
Why people choose them
They are seen as an upgrade from basic zoning because:
• You can name zones
• You can open and close zones separately
• Control feels more modern than push buttons
Where they still fall short
• Zones are still large groups, not individual rooms
• Most cannot control Airflow
• The system still reads temperature from one hallway location
• Comfort varies room by room
• The whole home is still treated as one temperature target
Integrated controllers feel modern on the surface, but the underlying logic is similar to basic zoning. They help, but not enough.
3. Smart controllers
Smart controllers are the newest category and they represent the direction the industry is moving.
What they are
• Mobile first control
• Room by room zoning
• Temperature sensors inside real rooms
• Precise airflow control
• Automations based on time, weather or routines
• Remote access from anywhere
• Clear visibility of what is happening across the home
Why they matter
Smart controllers solve the comfort and efficiency issues that older systems simply cannot fix.
They allow you to:
• Cool or warm only the rooms you are using
• Avoid cooling empty spaces
• Fix hot and cold spots
• Automate comfort around your day
• Reduce energy waste from overrunning
• Achieve a more stable temperature with less effort
Where they excel
Smart controllers shift air conditioning from a “whole house” approach to a “room by room” approach. That is the difference between comfort that feels random and comfort that feels effortless.
So what is the “best” air con controller?
When people ask for the “best” air con controller, they usually think they are choosing between different looking panels. The real difference is in how the controller understands your home.
Basic and integrated controllers treat the home as one space.
Smart controllers treat the home as a collection of rooms, each with unique comfort needs.
The future of air conditioning is not about adding more buttons.
It is about giving each room a voice and letting the system respond intelligently.
