Air Conditioning Options

As you probably know, the Australian summertime can be extremely hot. When I moved to Australia from England, I knew it would be warm, but I wasn't ready for the intense heat. I had bought a home on the outskirts of Sydney. It was a great place but unfortunately, it didn't have an HVAC system. I moved in during the winter time, so this wasn't a problem. However, when the weather began to warm up, the interior of my home became very uncomfortable. I called in an HVAC contractor who explained my options before installing a modern HVAC system which keeps my house nice and cool.

The Applications of Reverse Cycle Heating and Cooling

by Herminia Lopez

If you're looking to take climate control within your home to the next level, a reverse cycle heating and cooling system is the way to go. As opposed to traditional AC systems, it achieves both heating and cooling efficiency for your premises. The system is also highly customizable, providing individualized control for multiple rooms. This makes such systems a great option for office and commercial spaces.

It is important to understand more about reverse cycle heating and cooling in order to select the best systems for your premises.

How reverse cycle heating and cooling works

The reverse cycle works on the heat pump principle. During this process, the AC system uses a fan to draw hot air from the premises and to pass it over a cooling liquid (the refrigerant). The resulting cool air is then redirected into the premises to offer cooler conditions.

The refrigerant, which is now warm because it has absorbed heat, is pumped to a heat exchanger that is located outside the premises. The heat exchanger allows heat to escape and enables the refrigerant to cool again. The process is thus repeated.

With reverse cycle systems, this process can be reversed and used for both heating and cooling. This means that warm air within the premises can be cooled, and cool air can be warmed, all by the same system.

Benefits of reverse cycle systems

Energy efficiency

Homes and premises use a lot of energy when heating and cooling their homes. Reverse cycle heating and cooling is an energy efficient solution at keeping your premises climate-controlled. The system is highly efficient at heating and cooling air as desired by the operator.


Reverse cycle systems are highly reliable and dependable solutions. Once installed and properly maintained, they can last for a long time.


Reverse systems can be used in homes, offices, schools and other commercial buildings. They come in both small and large sizes, and can be adapted to many different areas.

       What to consider when selecting a reverse cycle system

When considering installing a reverse system, you should take into account the nature of your premises and what your specific needs are. Consider the following important factors:

  • The floor plan of the premises: consider the number of rooms in the building, the number of levels, and how the rooms are structured.
  • Size and positioning of doors and windows
  • The number of people in the premises
  • How much outdoor space is available: a compressor will need to be installed outside the premises. Adequate space should therefore be available.
  • The quality and availability of power supply for the system.
