Split System and Ducted Air Conditioning

Split System Air conditioning vs Central Air Conditioning for Commercial Space

The main difference between air conditioning split systems and ducted air conditioning is how air is distributed throughout the space.

Split System Air Conditioning

    • They require a dedicated indoor unit in every separate room requiring conditioned air.
    • Each indoor unit has a small fan that pushes the cooled or heated air directly into the living space.
    • Such systems are great for cooling and heating open-concept homes with a few rooms or rooms where doors can be left open, allowing air to travel and cool or heat these spaces.
    • Such systems can have multiple heads in residential homes or commercial environments to service more than one room.

Split system air conditioning are ideal for cooling and heating open-concept homes with few rooms or rooms with doors left open. Ducted air conditioning are best for large spaces or commercial buildings that are relatively expansive. Split system air conditioning are more energy-efficient and cost-effective than ducted aircon units.

Split system air conditioning have two main components: an indoor unit and an outdoor unit. The indoor unit is typically mounted on a wall or ceiling inside the room or cooled/heated area, while the outdoor unit is placed outside the building. Refrigerant lines connect these two units. Split system air conditioning cool rooms independently, allowing for personalised temperature control in different areas. Each indoor unit has its own controls and can be operated independently.

Ducted Air Conditioning

Ducted air conditioning offers zoning and control, which allows for flexibility. Zoning allows the user to set the climate of each room individually. This provides greater control over the airflow around the home and allows flexibility to use the system to suit living arrangements.

Some zoned ducted systems allow users to divide a space into four dedicated air-conditioned zones. Ducted air conditioning zone control options offer the best in airflow control, flexibility, and energy efficiency. The following are some benefits of installing a ducted air conditioning system:

Improved energy efficiency: Ducted air conditioning systems allow cooling or heating only the areas that are used regularly, which reduces energy consumption and saves money on utility bills.

Customisation options: This system provides greater control over the airflow around the commercial or residential space. It also provides flexibility to use the system to suit individual arrangements.

Increased HVAC system life: The zoning feature can help extend the life of the HVAC system by reducing wear and tear on the equipment.

Quieter heating and cooling: Ducted air conditioning systems can help reduce noise levels by allowing users to turn off the air conditioning in unoccupied rooms.

Regulating temperature and airflow: Zoning works by regulating the temperature and airflow in different home rooms, providing greater comfort and control.

Increased energy savings: A zoned AC system can signify increased energy savings with more control over each zone, including turning zones off when not in use.


It is recommended to use ducted air conditioning for larger or commercial spaces for better temperature management and greater control. However, the better option for commercial space cooling or heating depends on factors such as the size of the space, zoning requirements, energy efficiency goals, installation considerations, and budget. It’s advisable to consult with commercial/residential air conditioning experts who can assess the specific needs of the commercial space and provide recommendations based on those requirements.
