People more often think about buying a reverse cycle air conditioner in the summer. During the hot season, it is easy to forget about heating in the winter months. Nevertheless, it is better to take this nuance into account in advance. Air conditioning with heating function is the most profitable solution. 
Most regions of Australia have seasonal temperature fluctuations. Even living in a mild climate, people face night frosts. In some areas, increased humidity is added to temperature differences, in others, too dry air is a problem. Excessive dust leads to additional stress on the lungs. 

More efficiency with reverse cycle air conditioning

The reverse cycle air conditioning system allows you to change modes with the touch of a button on the remote control. This solution saves space. People do not need to install two types of equipment.

Reverse cycle air conditioners are also more energy-efficient compared to standard heaters. Read about all the benefits later in this article.

Winter heating with reverse cycle air conditioning

A conventional electric or gas heater generates thermal energy from scratch. It takes a lot of time. A large amount of natural resources is also consumed. In addition to not very high efficiency, users of this type of equipment are forced to agree to high operating costs.

A reverse cycle air conditioner operates in a completely different way. The system collects heat from the outside air and pumps it into the room. Air undergoes additional filtration. It does not mean that heating is possible only at a favorable temperature outside. The mechanism works like this:

  • The refrigerant passes through an external coil and absorbs heat from the outside air
  • The same refrigerant is pumped through the compressor into the fan coil inside the house
  • Heat is generated in the room

Modern models can effectively heat homes at -15 ֯ C outdoor temperature.

Best Air Conditioner – Review of 2020

Reverse cycle air conditioning: kill two birds with one stone

When it comes to choosing home appliances, it is always preferable to buy a machine that can perform several functions. The term reverse cycle implies that one piece of equipment can carry out two opposite operations. In other words, it can cool the indoor air in summertime and warm it up in winter. So you get cooling and heating equipment by installing just one electric device. It is a great option for our climate zone where summer is hot and long, but winter is short and mild.

How can one system perform two different functions?

A reverse cycle air conditioning is deliberately designed to operate in two modes. Besides standard cooling function, it can carry out a reverse operation by heating the surrounding air. By inverting the refrigeration cycle, this device provides both types of air conditioning. Altering the cooling process into heating is performed by a built-in inventor. That is why they use such labels as inventor or non-inventor, the latter meaning that the unit performs cooling operation only. When used in heating mode, the inventor reverses the cycle in both components of the system:

  • the indoor evaporator coil performs as a condenser coil and emits heat,
  • the outdoor condenser functions as the evaporator and releases cold air outward.

Moreover, reverse cycle systems have several advantages besides standard cooling and heating options.

Pros of implementing reverse cycle system

Reverse cycle air conditioning efficiency

When choosing an air conditioner, the primary criterion that comes to mind is its energy consumption. With long and hot summers in our region, cooling the air inside the premises can considerably affect electricity bills. Reverse cycle system provides efficient use of electricity by producing three kW of desired effect consuming only one kW of energy regardless of which mode is used. Furthermore, modern models have many useful settings that allow noticeably reduce energy consumption whenever it is possible.

Reverse cycle air conditioning adaptability and flexibility

Thanks to a built-in thermostat and smart technology, you can customize indoor air conditions as needed. A whole range of settings allows choosing not only the temperature and the fan’s speed but also gives control over energy usage and the indoor air humidity. The system can dehumidify the air with dry function and decrease energy usage with economy function. The latter can either regulate the thermostat by a few degrees or using a built-in sensor to detect the presence of people in the room and reduce the production of cool or heat accordingly.

Air purifying function provides a healthy environment

Some split type systems have air filters that efficiently trap undesired particles, thus reducing dust in the air. The more advanced models can even eliminate unpleasant odors by decomposing them and absorb harmful particles such as bacteria and viruses. These features provide comfortable air conditions for those who suffer from various allergies and asthma.

Reverse cycle air conditioning noiselessness

Another factor that deserves consideration while choosing an air condition system is how much noise it produces when in use. Keeping that in mind, some manufactures of reverse cycle systems employ advanced technologies that significantly decrease humming sound across the system components.


There are two advantages to utilizing a reverse cycle system as a means of heating. Though electric heaters are inexpensive, they are not efficient from the energy consumption point of view. So, in the long run, they become expensive to operate. Using an air conditioner as a heater, on the contrary, considerably saves energy. The second benefit of implementing a reverse cycle system is the lessened amount of greenhouse gas emitted into the air. It yields only one-third of harmful emissions produced by a typical electric heater.

What is the difference between split and ducted systems?

The only distinction between these two types of reverse cycle system is your intention. If you intend to set up a climate control in one room, the split type air conditioner is a reasonable option. In this case, the indoor component of the system is placed on one of the walls, which in turn, will discharge hot or cold air inside that room only. If you intend to equip the entire house or several zones of the building with climate control, then duct type system is preferable. In that case, the indoor component is installed in the roof space, which in turn, will pump the desired type of air into several vents located in the ceiling duct across the house.

What is reverse cycle?

Air conditioner with heating and cooling function, allows you to switch modes with one button. In heater mode, the reverse cycle extracts heat from the outside air and draws it into the room.

What’s the difference between split system and reverse cycle?

The reverse cycle is an air conditioner with a heating function. A split system is a type of air conditioner. Split systems can be either with a reverse cycle or without it.

How does reverse cycle work?

A reverse cycle air conditioner draws in heat from the outside air to heat the air inside. This approach is more energy efficient than traditional heaters.

Is reverse cycle heating efficient?

A split system with a reverse cycle has an efficiency of 300–600%. Ducted systems are not as efficient as wall units because a larger fan is used and energy is lost through the ducts.
