Systems We Install

Chief Electricians air conditioning system install

Over the years we have worked with hundreds of different split air conditioning brands and products. With our first-hand experience, Chief Electricians will always recommend products from either Mitsubishi or Bonair’s range of split air conditioning systems to be installed in Melbourne. Their proven designs & reliability means you will have a system that can operate in Victoria’s ever-changing weather conditions and harsh ocean-facing environments.

A split air conditioning system uses two units working together: an inside unit and a compressor/ condensing unit outside. It works by expelling the hot air inside your house to the outside and replacing it with circulated cool air. Inside the system, you’ll find a compressor, a fan, an evaporator coil and a refrigerant. It is the most efficient way to change the temperature in your property.

The main differences between a split system and a central air conditioning system is the price, amount of maintenance, the overall look of each system & the complexity. A ducted system requires an installation that can be done throughout the rooms of the property with ducting, vents and other items requiring to be installed. A split system is less complicated and can be installed in a wider variety of situations that are easier to manage for homes or businesses.

Ducted air conditioning systems are designed to cool and heat an entire home. They have an outdoor unit, and a central indoor unit, usually installed in the ceiling or under the floor. Air ducts run from the indoor unit to air outlets and sensors in each room.

A ducted air conditioning system can be a prohibitive cost. Before you spend many thousands of dollars to have a system installed (and hundreds of dollars per year to run it), consider other cooling and heating options, such as separate split-system air conditioners.

A split heating and cooling system like those provided by Mitsubishi provides a customizable experience that gives you the power to create the perfect indoor temperature from room to room while allowing you to save money in the process. These systems are also easier to install than ducted systems, and they utilize energy more efficiently.

A split system works by using a single heating and cooling unit that connects to units and thermostats placed in desired rooms. This means you can change the temperature in one room without affecting another which helps slash utility bills.

When it comes to saving money and using energy efficiently, split systems from companies like Mitsubishi stand head and shoulders above traditional ducted systems. This is because systems that use ducts require you to heat or cool your whole home or business when you change the thermostat, even if you just wish a single room was warmer or cooler. A split only uses energy to target the specific zones you choose. You lose less energy because you’re going straight from the source to the desired area, versus having the warm or cool air travel through ducts.

A ducted air conditioning system can make your house far more comfortable to live in, but its running costs can be high.

The purchase price of a ducted system. Choice states that you’d be hard-pressed to purchase a ducted reverse-cycle air conditioning system for less than $5000 (including installation).

That’s the entry level cost for a small home such as an apartment. For a typical freestanding house, the cost can easily reach $10,000 or more, depending on the size and type of system you choose. For a large or multi-floor home you’re probably looking at $15,000 or more.

When it comes to running costs of a ducted system, Craig Gibson on hi, wrote that assuming an electricity usage rate of 35c/kWh you can expect to outlay in the region of $3/hour to keep cool in summer, and $1.85/hour to stay warm in winter. These figures will also depend on the energy efficiency of your system and how many zones or rooms you want cooled/heated.

An interesting blog by Petro Home Services sets out that split systems do not require ductwork, making it the more convenient cooling option for older buildings with thick walls. It basically keeps your room temperature at a constant temperature, unlike an air conditioning unit that goes on and off throughout the day. In the winter, the system works in reverse by absorbing heat from the outside air and moving it indoors to heat your home, too.

Their compact size allows for greater flexibility in temperature zoning—air conditioning is limited to the rooms in which the air handlers are located. These systems tend to run quieter than central air conditioning systems and are easier to install.

A ducted air con system is one that’s installed in the ceiling with a series of ducts taking cool air to different rooms in your house. You can control which rooms are on at any one time and you can choose to install a system that heats as well as cools. 

A split system is generally designed for one room only. If all you want is air con in, say, your bedroom, this is a great way to achieve that. 

Their compact size allows for greater flexibility in temperature zoning—air conditioning is limited to the rooms in which the air handlers are located. These systems tend to run quieter than central air conditioning systems and are easier to install.

Choice states that the running costs and electricity used for a ducted aircon mainly depend on:

  • The type and size of your system
  • The energy efficiency of your system
  • The time you’re operating the system for
  • The construction of your home (floor plan, level of insulation, size of windows, etc.)
  • The electricity tariff you’re paying
  • The temperature you choose on the thermostat: each degree Celsius lower (cooler) you set it to in summer, and each degree higher (warmer) in winter, will increase the running costs by 10-15%.


Red Energy states that it can cost more than $3.00 per hour for a reverse-cycle unit that’s ducted to cool your entire house. If you run the system on most days over summer, the cost can quickly add up set out that the wall-mounted split system air conditioner is an ideal combination of cooling and heating – two systems in one. The compact indoor fan coil unit is quiet and unobtrusive in operation and blends into any modern decor. Multi-head split systems allow for several rooms to be cooled and heated independently from a single external unit.

On the other hand,, very quickly identifies a ducted system as quite an investment. Costs can range between $8,000 to $15,000. The type of ducted air conditioner required in your home is based on a lot of different factors. Ducted air conditioners are individualistic in their design and installation, so therefore the costs are more.

HiPages help explain some of the considerations to be made when choosing which type of system best suits your home.


Both ducted and split air con systems will do the job of cooling for you. The main things you need to consider are how many rooms you want to cool/hear and how much you want to spend.


If you only want to cool your living room, a wall mounted split system may be ideal for you. When choosing the system, you’ll first need to determine how large an area needs to be air conditioned and match that with the capacity of the system.


For an average 25 square metre bedroom, a 2.5-kilowatt (kW) system will usually be enough, but if you want to cool a 70-75 square metre living room, you’ll need a 7kW system.


A ducted air con system operates from a central location and warm or cool air is sent to the various rooms of the house via a network of ducts. A system like this is far more expensive than a split system, but if you want air conditioning throughout the house, it’s still less expensive than individual split systems for each room of the house.




Furthermore, CleanBC provide a list of extra considerations that will help you in deciding which heating/cooling option is suitable for your home.


The type of heat pump you choose will depend on a number of factors:

  • Size and layout of your home: Mini-split/ductless heat pumps can be used in homes of various sizes, but they are ideal for smaller homes or homes with an open plan layout.


  • State of your ducts: It’s important to check the ducts of your old heating system. Depending on their size, airtightness, and layout, a contractor may need to do some modifications and repairs prior to installing any new high efficiency heating system.


  • Interest in removing ducts: The ductless design of a mini-split heat pump makes them ideal for installation in homes that do not already have central ducted heating – for example, in homes with electric baseboards or when switching from a boiler system with radiant heating to a heat pump system. If you are interested in removing the ducting in your home to provide you with more headspace or a more efficient utilization of space, installing a mini-split/ductless heat pump will allow you to do so.


  • Zonal heat: The design of a ductless heat pump allows for zonal heating – that is, the ability to set different temperatures in different areas of your home. Zonal heating is an efficient and effective way of providing just the right amount of heat to the areas that are most commonly occupied in the home – such as common living spaces, home offices, bedrooms, and using less heat in areas that are not frequently used. Zonal heating is also useful for homes where the occupants have different heating preferences or for areas of the home that need separate heating controls – like a home with a rental suite.


  • Outdoor temperature: The heat pump you choose should be compatible with your region’s climate. Some models perform better than others in colder winter temperatures.



Mitsubishi Heavy Industries describe some benefits of using split systems to cool small spaces such as units or apartments. Single or Multi Split Systems are typically used in apartments due to the space limitations. Apartments tend to have smaller living spaces and limited outdoor space. This means that they need smaller capacity units to deliver the desired room temperature.




Craig Gibson from HiPages outlines how split systems are ideal for small spaces and rooms such as apartments. Split systems are the most common type of air conditioner worldwide and consists of two elements – an indoor head unit that blows air into your room and an outdoor compressor unit and an indoor unit connected by pipes.


Expect to cool one or two rooms with a split system or opt for a multi-split system where one outdoor unit drives to two or more indoor units.




Strata Community Association NSW provide further useful information about the logistics of installing a split system for apartment owners.


If you are considering installing a permanent split or ducted air conditioning system, gaining the approval of your strata’s owners corporation first is a must as this forms what is called a minor renovation under the new strata laws. To do this, you need to submit a proposal that includes the details regarding the system you seek to install – the brand, size, where you wish to locate the air conditioning unit, and so forth.


The owners corporation should be able to tell you whether there already exists a by-law about air conditioning and how it applies to your installation plans. If the air conditioning unit will require changes to common property – the drilling of holes into walls for piping, for example – a specific by-law may need to be written up before you can commence with the installation.


Maintenance and repairing of the air conditioning system, once installed, will likely be your individual responsibility. However, whether this is the case will be clarified during the approval process.


Source: outline the rough price that a split system air conditioner and install will cost. Although the upfront installation costs are more significant than a portable unit, these systems are usually one of the most cost-effective options in the long run.

How much it will cost you depends on the price of the units themselves, as well as a tradesperson’s fees to install them. Split air con units can vary dramatically in price from $600 to $5500, depending on:

  • the brand and model
  • size and capacity (measured in kilowatts – see what size you need)
  • smart features such as sensors, eco modes, Wi-Fi and app compatibility

This is carried out by a professional installer that is insured and registered to carry out the work.


You will need a professional to do the install to ensure your home and contents insurance is protected as any DIY work could void the warranty of the unit. It could also cause issues with your insurance should your installation prove faulty.


If you are installing multiple units in your property in one day, expect to pay less for your installation as the technician is onsite, so the costs for multiple units on average will be lower.



CanStarBlue provide a useful insight into approximate prices for mini split system operating prices in Melbourne as of the end of 2020.


Split system air conditioners are one of the most popular types of cooling and heating systems as they are fairly easy to install and comparatively affordable to purchase.


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.


It generally costs $0.13 – $0.36 per hour to use a reverse cycle air conditioner to warm a room.


This means, assuming you run your air conditioner, cooling for 2.5 hours every day for a year, the cost will be around $250-350 per unit. If using your reverse cycle split system to heat for 2.5 hours a day, you can expect to pay $130-360 per unit per year.





Additionally, Mitsubishi Heavy Industries provide information on the hourly running costs of their split system units.


The average modern reverse cycle air conditioner costs only around $0.13 – $0.36 per hour to run.


This comes in cheaper than most common household appliances including a clothes dryer ($0.50 – $3.14 per hour), vacuum cleaner ($0.41 – $0.82 per hour) iron ($0.41-$0.82 per hour) and even the humble microwave ($0.28 – $0.53 per hour). Cheaper than you thought, right?


Backed by Government research, reverse cycle air conditioners with high energy ratings, such as our industry leading 7 star rated 2.0kW Avanti PLUS® model, are the most energy efficient and cost effective solution for most heating spaces. While the upfront cost may be slightly higher, these units allow you to heat a space quickly and efficiently – saving you money in the long run!



The Good Guys offer information on the appropriate size room for 2.5kW split system units as well as a range of other sizes.


When buying air conditioners, your first consideration is likely to be how powerful the device needs to be to adequately cool your home. Air conditioner capacity is rated by BTU (British Thermal Unit) and power output in kilowatts. Buying the right size unit is very important as air conditioners that are too big will use more energy, while under-sized ones will not cool the room sufficiently.


When selecting the right size air conditioner for your space, the below applies:

  • For a room 10m2 to 20m2, a 2.6kW unit should cool the room;
  • For a room 20m2 to 30m2, a 3.5kW unit should cool the room;
  • For a room 30m2 to 45m2, a 5-6kW unit should cool the room; and
  • For a room 45m2 to 65m2, a 7-8kW unit should cool the room.




CanStarBlue give further information about how effective a 2.5kW system will be in your home.


When shopping for a new air conditioning unit there is more to consider than just the cost of the unit itself. The kilowatt capacity for the size of room that it’s tasked with cooling is much more of a priority. You could be saving yourself the heartache of a high electricity bill by carefully choosing the best air conditioner for the space it’s intended for 10-25 square metres – A small kitchen, bedroom, study, small lounge, small office – 2.5kW



The Victorian Building Authority (VBA) is the authority that regulates the building and plumbing industries, they also licence and register plumbers including those authorised to install or replace air-conditioners.

These practitioners are also required to hold a refrigerant handling licence and either hold an electrician’s licence (A grade) or engage a Registered Electrical Contractor (REC) registered by Energy Safe Victoria (ESV).

When installing a reverse cycle air-conditioner a VBA plumbing practitioner registration and a refrigerant handling licence is required and any electrical work must be completed by an REC. When replacing or repairing a reverse cycle air-conditioner VBA registration and a refrigerant handling licence is required and any electrical work must be completed by an REC. Note: if a system is disconnected and replaced with a new system of equivalent power and current in the same location without alteration to existing cables; the electrical work can be undertaken by the holder of a Restricted Electrical Workers Licence (REL) with the classification – Refrigeration and air-conditioning.

Remember Installing an air‐conditioning system is not a do‐it‐yourself job – you must use a suitably licensed person otherwise you are putting yourself and your family at risk. Anyone having an air‐conditioner installed or replaced is reminded to ensure the practitioner is appropriately licensed to perform this work. At the completion of the installation you must be given an ESV Certificate of Electrical Safety (COES) and a VBA Plumbing Compliance Certificate. Only properly trained, licenced and insured installers can provide you with these mandatory certificates that ensure your warranty for the appliance and the installation is guaranteed. You can check the licence status of an electrician using ESVConnect at: and VBA Plumber qualifications at: explains that even though split system air conditioners can be installed in waterfront properties near the beach, this can come with risks and damage to your air conditioning system.


In coastal areas, exposure to salt can result in coil damage that shortens the life of the equipment.

Environmental factors, such as airborne vapors from chemical plants and paper mills, cause substantial damage to HVAC coils each year. In coastal areas, however, the main cause of finned coil damage comes from Mother Nature.


Naturally occurring atmospheric conditions such as wind and hail from storms and erosion from sand blown in from the beach are contributing factors. But the exposure to salt air in these regions is by far the most destructive component to finned coils.


Condenser coil degradation impacts the entire mechanical cooling system. As the coil surface deteriorates, the coils can no longer transfer heat according to design specifications, thereby decreasing efficiency.


Head pressure begins to increase, causing nuisance shutdowns from the high-pressure limit system. Compressors and condenser fans must work harder, drawing more current and possibly shortening their life. This results in increased energy costs and premature component failure. Consequently, the equipment owner will see higher operating and repair costs.



UnderStand Solar explain how split systems air conditioners can be powered by solar panels installed on your house, depending on whether your property is located on or off-grid.


Can you use solar panels to run air conditioner units? In a word, yes. If your home is connected to the grid and your solar installation is net metered, it is possible to use solar energy to cool your house. Many homes already do this!


However, in another word: maybe. An AC unit requires a lot of electricity. If you live off-grid and have no method of backup power, your solar/battery system will need to be quite large.




Additionally, provides information on how effect solar panels can be at powering an air conditioner through a hot Australian summer.


If you have a home with good thermal performance, yes. You can get through a heatwave without spending a penny on grid electricity. The battery is a luxury though – as the vast majority of the savings will be from the solar panels.


If you want to reduce such a home’s impact on the grid on extreme days, then the most cost-effective way to do that is to improve the thermal efficiency of your home (gaps, glazing, insulation) and get the most efficient air conditioner you can.


If you combine that with a reasonably sized solar power system, your home can be transformed from being part of the problem to becoming part of the solution when these increasingly common heatwaves hit.
