Comparing zoning options for your ducted air conditioning
Discover the right balance of comfort and efficiency for your home layout.


Understanding Ducted Air Conditioning Zoning
Zoning divides your home into independently controlled sections. This enhances personal comfort while boosting energy efficiency by not conditioning unused rooms.
As a critical part of home electrification, switching from gas to a zoned ducted system allows you to accurately manage air volume and maintain consistent temperatures year-round using renewable energy.
Homeowners typically choose between three tiers of control based on their home layout, such as managing the distinct thermal needs of a double-storey house versus a single-storey open plan.
Choosing the right setup for your home
Before diving into the specific tiers, it is important to understand that zoning is essentially the “brain” of your ducted air conditioning system.
Selecting the right level of zoning depends largely on your home’s layout. For example, a multi-storey house has significantly different thermal requirements than a single-storey, open-plan home.
No Zoning
A standard ducted system treats the entire home as one large zone controlled by a single central thermostat. Every outlet receives the same air volume simultaneously. This is cost-effective but potentially inefficient for larger properties where some rooms remain empty. The system runs until the central thermostat area reaches the set temperature, regardless of hot or cold spots in outlying rooms

Simple Zoning
Simple zoning allows you to group rooms into sections that can be toggled on or off via the wall controller. It requires a master zone, typically the living area, to remain open to maintain the minimum airflow needed to protect the compressor. Most standard units can only scale down to 40% capacity, so this zone ensures the system stays within safe operating limits.

Temperature Controlled Zoning
Premium zoning provides individual thermostat control for every room using localised sensors and motorised zone barrels. This system modulates air volume precisely to maintain room-specific temperatures within 0.5-degree increments. It is critical for double-storey homes where heat rises. It requires advanced compressors that can scale output down to 20% to efficiently condition small areas.

The Benefits of First-party Control
First-party control means the zoning technology and the air conditioner are made by the same manufacturer, as seen with Actron Air’s integrated systems, ensuring seamless communication and native performance.
Integrated systems avoid the glitches of mismatched third-party controllers that struggle to sync with different unit brands. This unified approach provides a single warranty point, ensuring a factory-trained technician can service every component from sensors to the compressor.
