Wall mounted split systems are Australia’s most popular solution for heating and cooling single rooms. They’re easy to install, efficient to run and come in a range of designs.

Split systems are comprised of an indoor unit which is installed on an interior wall and an outdoor unit which is placed on an exterior wall of your home. Split systems provide a stylish and convenient solution to heating or cooling single rooms.

Our wall mounted units are available in a range of capacities to suit any home, with both reverse cycle and cool only models available.

How it works in super simple terms?

  1. A cold liquid called a refrigerant, passes through an external coil, absorbing heat from the air outside.
  2. The refrigerant is pumped by a compressor, down through chambers and into a condenser coil.
  3. As the refrigerant is compressed, it warms up, creating hot air.
  4. This hot air is pushed into the room by a fan from the indoor coil, to warm the area.
    To cool down your home, the reverse cycle air conditioner simply reverses the flow of the refrigerant.


Some benefits of wall mounted reverse cycle split systems are;

  • Being such a compact system in most cases we can install wall mounted systems after construction or in most established homes.
  • They are reverse cycle, keeping you cool in summer and nice and toasty in winter!
  • They are super efficient, In fact, modern reverse cycle air conditioning systems are becoming more efficient over time, particularly in terms of energy consumption and cost, making them a very good investment in comfort and health. And as electricity prices continue to rise, air conditioner efficiency is becoming increasingly important. They’re efficient even in the most extreme conditions with the systems we install made for Australian harsh climate. For example, one kW of electricity consumed, will generate three or more kW of heating or cooling.
  • Better for the environment with new technology and innovation being pushed every day. More split systems today are using the new R32 refrigerant with 66% lower global warming potential factor than R22 which is the common older, phased out refrigerant type.




Wall mounted AC FAQS

Where can I install a wall mounted system?

As mentioned above wall mounted systems have a lot of installation flexibility given the compact size of the systems. In most cases systems are installed on an external wall in order for us to run our piupe work and electrical outside easily. In saying that we do install split systems with restricted external wall space on internal walls, however in most cases a condensate pump is needed to pump the condensation when running on cooling from the indoor system and outside.

Can I install multiple indoor units to one single outdoor unit?

Yes, you definitely can! This is a lot more common in apartment style properties or houses during construction so pipe work and other services can be ran easily to the outdoor unit. The type of system is called a Multi head system and we install a lot all over Perth. If you have an established property in some cases this type of system can be quite hard to install although always possible given the layout and application.

What is an inverter?

An inverter in relation to air conditioning terms is a type of air conditioning system that incorporates a power conversion circuit which provides optimum power control and extremely efficient operation by changing the frequency of the power supply to the compressor which varies the cooling heating capacity, so even though you get accurate, smooth and flexible operation, you use less electricity than conventional units.

Please note that energy savings are only realized when the system is correctly sized. Undersized inverter systems will cost more to run than a correctly sized system. Inverter systems run much more efficiently at 30 to 70% of their full capacity.

What temperature should I run my system on when installed?

As a guide, somewhere between 22 and 24 degrees Celsius. Try to avoid setting your system on the coldest or warmest temperature, this will increase your electricity bill tenfold and your system will be working round the clock to try and reach the set temperature.

What is a back-to-back installation?

A back to back wall mounted split system installation is generally the most cost effective option. The indoor unit is mounted backing onto an exterior wall. The outdoor unit is directly behind it. Both the indoor and outdoor unit are, as the name suggests, back to back. One key thing to remember is all systems require a minimum pipe run, ensure your system has a 3m pipe run where possible in order for maximum unit efficiency.

Why is my aircon leaking water externally?

This is a common worry among clients, generally in the winter. When your reverse cycle system is running on cooling the outdoor unit will generally drip from the bottom drain exit on the system, this is a normal condensation process as the outdoor coil is cold when running on heating. This is the opposite when running on cooling, the indoor system will be the unit with excess condensation of water, however this will still be drained externally due to the connection of a length of drain.

It is very important that when servicing your split system annually the refrigeration mechanic cleans the drain line and checks for blockages.

Will be system need re gassing in the future?

Unlike the automobile air-conditioning system, all residential and commercial refrigerant is non-combustible and will not need topping up unless there is a refrigerant leak on the system.

Do you offer warranty? – All of our workmanship is backed by a 5 year workmanship warranty giving you peace of mind that our technicians are awesome!

How energy efficient are reverse cycle wall mounted air conditioning units?

The average reverse cycle air conditioner costs around $0.25 – $0.35 per hour to run for cooling purposes, depending on the size of the room. A medium-sized room of 36sqm would cost $0.36 – $0.70 per hour to run. In large areas (50sqm), it will cost between $0.70 and $0.95 per hour.

Below the prices are usage assumptions for air con use, which take into account the energy efficiency of a device according to the Climate Zone you live in. For example, you’ll see that a Brisbane household will use much more than one in Melbourne, since the system has to work harder to balance out the hot external temperature.

When running your system on heating, It generally costs $0.13 – $0.36 per hour to use a reverse cycle air conditioner to warm a room.

The table below reveals the annual costs of using your air con to heat, rather than cool. The usage figures below the costs reflect the demand for heating in each state, as well as how energy efficient an appliance can be depending on the climate zone. In this scenario, a Melbourne household uses significantly more hot air con than a Brisbane one, since it’s much colder there year-round

As per Canstar Blue study;

Canstar Blue highlights that on average using your air conditioner in winter will generally cost you between $0.13 -$0.36* per hour to use a reverse cycle split system air conditioner to warm a room.
