Guide to buying a Ducted Reverse Cycle Air Conditioning.

Searching for the perfect fix for your cooling and heating problems?

Imagine a home with a quality and comfortable air conditioning system where the kids enjoy cool air in the living room playing video games, a cozy living room for relaxation after dinner, and a comforting and warming bedroom. This comes with high cost and planning that requires experts in ducted reverse cycle air conditioning, like Scott Brophy from Reef Air.

What is ducted reverse cycle air?

Ducted reverse cycle air conditioning provides efficient cooling and heating comfort to every part of your home at the touch of a button. It is comprised of a central indoor and outdoor unit. The main indoor unit is often mounted under the floor or in the ceiling. Air outlets and sensors are placed in each room and are connected to the indoor unit through air ducts.

Should the cost implication of having ducted reverse cycle air conditioning be considered?

A cooling and heating system like a ducted reverse cycle air conditioning installed in the entire home is the ultimate. However, the installation and yearly maintenance costs are enormous.  It is recommended that you consider installing split-system air conditioners as an option in major rooms in the home for maximum cooling and heating effect, especially during the summer and winter seasons.

What’s ‘reverse cycle’?

Reverse cycle refers to an air conditioner type that possesses heating and cooling functions. A reverse cycle is an air conditioner in which the refrigeration system can reverse from one state to another, generating heat rather than cooling and vice versa. It is two systems in one that operates simultaneously and efficiently. Air conditioners work on a principle called the heat pump principle. Heat is pumped from one location to another.

Below is the refrigeration cycle of an air conditioner

  • The warm air indoor is drawn into the indoor air conditioner unit through a vent over a cold refrigerant. The refrigerant absorbs the heat in the warm air, leaving a cooled air that is sent back into your home.
  • The warm refrigerant evaporates and enters the compressor that is positioned outdoor. The compressor raises the pressure and temperature of the refrigerant.
  • The refrigerant (with high temperature and pressure) passes through a heat exchanger where its temperature and pressure are reduced, resulting in heat transfer. The refrigerant is now cool and liquefied once again.
  • The refrigerant passes through an expansion device that further reduces its temperature and pressure to enable the refrigerant to re-absorb heat. The entire process (1-4) is repeated.

ducted reverse cycle air conditioning FROM REEF AIRWhat are the methods for selecting the perfect ducted reverse cycle air conditioning for your home?

Do you want to install a ducted reverse cycle air conditioning in your new home, or you want it tailored to suit an existing one? You are certainly at the right place. Some experts will guide you through every step towards installing a reverse cycle air conditioning in your home to optimize your home’s air conditioner. Scott Brophy from Reef Air Conditioning will provide you with the best quotes and designs.

Below are the details you should take into consideration before the installation of a ducted reverse cycle air conditioning:

  • Home floor plan: The floor plan provides the room dimensions (including the height of the ceiling), how the rooms are positioned, and the number of levels the building has
  • The purpose of each room (e.g., for cooking, living, or sleeping) should be stated.
  • The number of inhabitants in the home
  • The home’s outdoor space – there should be space outside the house for the installation of the compressor. The compressor should be located such that your neighbours will not be affected by the noise from the compressor.
  • The type of building construction should be known—for instance, a full brick or weatherboard construction.
  • The nature of the ceiling space should be considered, as underfloor ducts might be required for limited ceiling space.
  • The position and dimensions of the doors and windows.
  • The availability of a three phase power supply.
  • The number of insulation in the walls, ceilings and beneath the floor.

Design features to be considered in the installation of a ducted reverse cycle air conditioning.

The structural components of your home require our experts like Scott Brophy from Reef Air Conditioning to provide a range of options outlined below for the installation.

  • Vents of suitable design are fitted into the ceilings and walls of your home.
  • Controls furnished with physically connected cables to your home’s existing wiring are fitted on the walls or ceilings. Depending on the size of your home, there might have more than one controller installed.
  • The controllers utilize sensors to regulate the air temperature in the rooms. An open space might need several sensors.
  • Most ducted reverse cycle conditioning system provides a home to be subdivided into zones for comfort and efficiency. With the creation of zones, the air conditioner can be turned on in all the rooms and floors you want to be cooled or heated at specific times.


Ducts created for ducted reverse cycle air conditioning systems by our experts are done per the ducting industry association, ADMA, the standard for ductwork (AS 4254). Our experts know that ducting is an integral part of this air conditioning system, and the ducts should have high thermal efficiency. This prevents the loss of significant cooling and heating as cooled and heated air moves between each room and the air conditioner. Our customers don’t need to worry about us installing inferior ducting. They are free to check our ducting work to be doubly sure it meets the Australian standard for ductwork.

How energy efficient are ducted reverse cycle air conditioning systems?

A reverse cycle air conditioning system must satisfy the requirements for minimum thermal or energy performance. Newly designed air conditioners have a high thermal efficiency that produces at least three kilowatts (kW) of cooling or heating capacity per kilowatt (kW) of electrical energy consumed. The energy rating of windows and split air conditioners are found on the manufacturer’s label, fitted on the body of the air conditioner but not so for ducted reverse cycle air conditioning.

Purchase and Maintenance cost

The price for a ducted reverse cycle air conditioning system varies with the size of your home. Subject to the inspection of your home, you can only get the best quote and price (inclusive of installation) at Reef Air Conditioning. It cost at least $5,000 for an apartment and up to $10,000 for a typical standalone home. You could budget at least $15,000 for a home with multiple floors. We have enjoyed many referrals from our existing customers and gotten recommendations from online forums for our professional and excellent service.

We look forward to installing a ducted reverse cycle air conditioning system in your new or existing home.

The cost of maintenance depends on:

  • The size, type, energy efficiency, and required time of operation of your ducted reverse cycle air conditioning system
  • The structural details of your home including the floor plan, window sizes, type of insulation, etc.
  • The type of electricity supply (single or three-phase supply) you consume and pay for
  • The temperature in which the thermostat operates. It increases your maintenance cost by 10-15% for each degree of temperature Celsius (either lower or higher)

Measures to reduce your maintenance cost

Following our several years of experience in the air conditioning business at Reef Air Conditioning, the below maintenance cost-saving measures should be adhered to:

  • Shut all outside doors and windows during the operation of your ducted reverse cycle air conditioning system.
  • Ensure you shade your home windows to keep the heat away in hot summer and trap the heat inside cold nights.
  • Turn on your air conditioner as early as possible when you expect a sunny day; commence heating early if you expect the day to be cold.
