Ducted Reverse Cycle Air Conditioning


Ducted reverse cycle air conditioners are designed to heat and cool your entire home. They provide precise climate control and are the ultimate solution for your heating and cooling needs.

Reverse cycle systems also allow for zoning, which means you can adjust the amount of air flow into each room, or even turn rooms off, allowing for greater efficiency and more precise temperature control.

Who should use a ducted reverse cycle system?


Ducted reverse cycle systems are great for anyone wanting the ability to heat and cool their entire home. They are not intended to be paired with existing ducted systems (eg. gas heating or ducted evaporative systems). In some cases, reverse cycle systems can be paired with wall split systems if there are rooms that are semi-detached or have limited ceiling space.

Ducted reverse cycle systems also require ample ceiling space for the indoor unit and ductwork, and a well ventilated space outside for the outdoor condenser.

Some other things to consider are:

  • The layout of your home: how many levels are there? What are the dimensions of the rooms (including ceiling height)?
  • The size, position and orientation of windows and doors.
  • The type of construction (eg. brick, weatherboard).
  • The amount of insulation in the ceiling, under the floor and in the walls.
  • The number of people living in your home.
  • The main use of each area (for example, sleeping, living, cooking).
  • Large systems might require a three-phase power supply, which will be an extra installation cost if you don't already have it.

What are the upfront and ongoing costs associated with running a ducted reverse cycle system?


To install a ducted reverse cycle system it can cost between $5,000 and $20,000 (or more!) - depending on the size of the system, zoning, outlets, ducting requirements and even smart controllers. When choosing a reverse-cycle system, it’s important to choose a system that has the capacity to effectively do its job, so it’s both energy-efficient and the best value for money.

Running costs of a system vary depending on usage and the space that needs to be heated/cooled. For example, an air conditioner that uses 5kW of electricity would use approximately $1.90/hr based on an electricity rate of $0.38/kWh.

Reducing the cost of running a ducted reverse cycle system


No one wants to spend a small fortune heating and cooling their home, so there are a few ways to reduce your running costs.

Firstly, ask for an inverter system when making your purchase. Inverter systems ramp the fan’s power up and down as required, in response to temperature fluctuations in the room. This type of system will reduce energy usage, as opposed to a system that is constantly operating at full capacity.

Secondly, consider adding zones to your system. This allows you to pick and choose which rooms you want to target, without having to pay to heat/cool the whole house.

Thirdly, as with most things in life, good practice goes a long way. It might seem counter-intuitive, but setting your system to a consistent cooler temperature in winter or warmer temperature in summer means that your air conditioner doesn’t need to work as hard. Another simple practice is closing your blinds and doors to reduce heat absorption on warmer days, and trap in the warm air when it’s cool outside.

Finally, consider adding solar. Installing solar panels can significantly reduce your running power costs, especially in Adelaide’s scorching summers. Using the power generated from your solar system means you won’t need to draw (as much) power from the grid. In some cases you might even get paid for using your A/C if your solar is feeding back into the grid!

Features to consider


  • Zoning
  • Ducting (more on that below)
  • Smart home functionality
  • Noise-efficiency
  • Air distribution (avoiding hot or cold spots in your home)
  • Value for money
  • Aesthetics (you may consider - or require - a different approach to standard ceiling outlets and remotes)

Standard v R15 ducting


Ducting is the insulated tubing that carries air from the indoor unit in your roof space to the outlet in each room. Ducting has an insulation rating, which is measured as an ‘R-Value’.

  • R1.0 is cheaper but less efficient
  • R1.5 is more expensive but more efficient
  • R1.5 is required in Climate Zones 4 & 6.
