Here in Sydney, we experience a wide-ranging climate, with sweltering summers and winters that, while not as bad as many other parts of the word, can get quite chilly.

On top of this, many houses here (particularly older ones) are poorly insulated, which can make them feel icy cold in winter and quite stuffy in summer.

Because of this, it’s likely that you will need an air conditioner that both heats and cools to stay comfortable all year around. The solution? Reverse cycle air conditioning.

Reverse cycle air conditioning is ideal in Sydney because it has both heating and cooling capabilities, so it’s the most energy efficient option available.

A reverse cycle air conditioning is a unit that has both heating and cooling capabilities. This is the most energy efficient way to control the climate in your home in both winter and summer as you will only need to install a single system, rather than separate ones for different seasons.

Everything You Need to Know About Reverse Cycle Air Conditioning in Sydney

How Do They Work?

The way that reverse cycle air conditioning (also known as heat pumps) work is quite simple. They function in a similar way to a refrigerator in that they have an internal coil and external coil, which are connected by piping that is filled with refrigerant.

When the unit is being used to warm a room, refrigerant is pumped from the compressor to the internal coil as a high pressure, producing heat, the refrigerant is then passed through the external coil expelling any cold air picked up at the internal coil.

When the unit is in cooling mode, the role of the two coils is reversed by reversing the flow of the refrigerant.

What Are The Benefits of Using a Reverse Cycle Air Conditioning?

There is a number of benefits of using a reverse cycle air conditioning:

● They are one of the most energy efficient ways to control the climate in your home
● They provide both heating and cooling, so you only have to buy a single system
● They remain cool to touch at all times because they have no exposed elements or flames
● They also filter and dehumidify the air
● They are flexible, with a range of configurations and features to suit the needs of any home
● They run very quietly
● They are better for the environment
● They are extremely sturdy and will last for many years

What Kinds of Reverse Cycle Air Conditioning Are There?

The are different types of reverse cycle air conditioning to choose from, and deciding which is best for your home will depend on a few things, like how big your home is and how many rooms you wish to heat/cool.

Split Systems

This is the kind of system where the condenser is fixed externally outside the home and the head unit is fixed inside the home.

These are connected by piping, which carries the refrigerant. The indoor unit is usually fitted to a wall.

Split systems are area-specific, meaning they are limited to cooling/heating a single room so they are best suited to small properties or apartments. If the ability to heat or cool multiple rooms is needed, a multi-split system may be the better option for you.

Why should you choose a wall-mounted AC system?

When it comes to choosing an AC system, there are so many different options. From complex ducted air con to simple window AC units, there is a different opportunity to suit the unique needs of every customer.

Today, let’s take a closer look at wall-mounted split system air conditioners and their many benefits.

What is a wall-mounted AC unit?

Wall-mounted, split system AC units, are the most popular type of AC units for homes and are designed to cool and/or heat either small or large residential areas.

A split air conditioner consists of an outdoor unit and an indoor unit. The outdoor unit is installed on or near the exterior wall of the room that you wish to cool.

This unit houses the compressor, condenser coil and the expansion coil or capillary tubing. The sleek-looking indoor unit contains the cooling coil, a long blower and an air filter.

If you require multiple rooms or various room temperatures, multi-split systems function the same as a split system; however, comprise of a single outdoor unit connected to multiple independent indoor units.

Let’s explore why wall-mounted AC systems are an excellent choice for your property.


Wall-mounted AC systems tend to be one of the most economical options for those looking for a cost-effective solution to aircon needs.

While window units or even portable units appear to be far cheaper, split systems will save money significantly in the long run, due to their increased energy efficiency.

Although centralised HVAC systems tend to offer lower running costs, when you factor in the initial outlay for installation, a wall-mounted unit is often the most affordable option.


For many, the aesthetics of their home or building is an important factor. The sleek design of the new wall air conditioner means that it can be easily placed in almost any room and look great.

Modern wall mounted units are designed to be slimmer and smaller than their older counterparts and far more aesthetically pleasing than the bulky window and portable units.

Unlike central HVAC systems that can require considerable disruption for installation, a wall-mounted unit causes very little damage to decor and aesthetics during installation.


Another great benefit of wall mounted air con units is that there is a great variety of options available.

Many reputable and established manufacturers offer a range of wall-mounted appliances, in different sizes, capacities and efficiencies.

Many models also feature timers and other advanced features to allow you to maximise energy savings and reduce your electricity bills even in the height of summer.

Multi-Split Systems

Multi-split systems are systems with more than one indoor unit connected to a single outdoor unit.

These systems can have up to seven internal units, and each one can be controlled independently. This means that specific rooms can be set at different temperatures, all from a remote.

They are great for larger homes, or homes that wish to be able to control the temperature in several rooms.

Ducted AC Systems

Ducted systems consist of a heat pump, which is located outside or in a roof space, ducting that distributes the warm or cool air throughout a house, and vents that blow the conditioned air into a room.

This type of air con will require a certain amount of cavity space for installation, so may not be suited to every home.

They are best suited to larger homes or commercial spaces looking to control the temperature throughout the entire building. Some ducted systems even allow for separate zones, meaning you have temperature control of individual rooms.
