FAQs - Air Conditioning Brisbane

Most air conditioning installs take a single day, although larger ducted air conditioners can stretch to two days.

Split system

In a split system, the indoor unit is mounted high on the wall, and the outdoor unit is placed in a discreet location so that it doesn’t disturb anyone.

Ducted system

For ducted systems, the indoor unit is typically installed in the ceiling cavity, although it can also be installed underneath the floor if necessary. As with split systems, the outdoor unit is placed in a discreet location, away from living areas.

As a leading Brisbane air conditioning company, we recommend premium air conditioners from Panasonic, Daikin, and Mitsubishi. These high-quality air conditioning systems are more efficient and economical, and last longer. In addition, these brands have the highest star ratings which is a key factor in determining the energy efficiency of your new Brisbane air conditioning system.

Our installation process

To determine the ideal air conditioner for your property, we may need to review information such as your architectural or house plans, the pitch of your roof (or the space below your flooring), and whether there is asbestos present. We may also need to understand your floor plan and internal structure, the available power supply, the number of windows and doors, how many people are on the property, and potential heat loads from electrical appliances.

We’ll obtain any of the information we need after our initial chat with you.

Existing properties

  1. We’ll chat to you about your needs, and if necessary, visit your property for a quick inspection
  2. We’ll recommend an air conditioning system for you, based on your needs and preferences
  3. We’ll arrange a date to install the air conditioner, and complete the install within a day (1-2 hours for a split system).
  4. We’ll provide you full instructions on how to run your air conditioner, and your warranty information

New builds

  1. We’ll chat to you about your needs, and inspect your architectural plans (if you have them). We can also work directly with your builders, if you’d prefer.
  2. We’ll recommend an air conditioning system for you, based on your needs and preferences
  3. We’ll arrange a date to install the air conditioner. For new builds, the install is quickest and cheapest immediately after the roof and electrical work are complete, and we’ll work with your builders to accomplish this. We’ll complete the install within a day (2-3 hours for a split system).
  4. We’ll provide you full instructions on how to run your air conditioner, and your warranty information

We love installing air conditioners in new builds, because it’s usually much easier to conceal the system and place vents in the optimum positions (for ducted systems). Ideally, we’ll install the system during the “frame” stage of the build, when the roof and electrical work have been finished. First we install the ducting, the indoor unit, the connecting cables, and the copper piping. Once done, we’ll tackle the outdoor unit, the vents, and the central control system.

Air conditioner replacements or upgrades

If you have an older air conditioner, you could be wasting a substantial amount of money on electricity. Newer systems have better technology and more efficient refrigerants like R32, which can drastically improve their efficiency.

To determine whether your system is worth replacing, we’ll visit for an inspection. If it’s a ducted system, we’ll pay attention to components like the ducting, vents, and the indoor and outdoor units. If it’s a smaller split system, we’ll review the system as a whole to give you our opinion on whether it’s worth replacing.

Once we have what we need, we can make a recommendation for you, provide an official quote, and get started on the work if you’re happy. This work also includes disposal of your existing air conditioner, including old ducting and the unit themselves.

What size air conditioner do I need?

Split system

When selecting a split system for individual rooms/areas, this is a rough guide to follow:

  • 10m2 to 20m2 room = 2.6kW unit
  • 20m2 to 30m2 room = 3.5kW unit
  • 30m2 to 45m2 room = 5 to 6kW unit
  • 45m2 to 65m2 room = 7 to 8kW unit


Calculating the required size of a ducted air conditioner is a little more tricky, and requires three steps:

1. Determine the total floor area of the space that needs to be cooled:
This is usually the living areas and bedrooms. We’ll use 100m2 for our example.

2. Calculate the total wattage for the air conditioner
To calculate the required wattage for the AC system, you’ll need to do the following:

  • For properties with a ceiling height of 2.4 metres: multiply the total floor area by 150 (watts)
  • For properties with a ceiling height of 2.7 metres: multiply the total floor area by 160 (watts)
  • For properties with a ceiling height greater than 2.7 metres: multiply the total floor area by 175 (watts

Let’s say your property has a ceiling height of 2.7 metres. Our calculation would be 100 x 160, which comes to 16,000 watts.

3. Convert to kilowatts
Now, all we need to do is convert our number to kilowatts. To do so, simply add a decimal point three places from the end of the number. In our 16,000 watts example, this would convert to 16.000 kW, in which case you’ll need a 16kW system.

How much does air conditioning cost?

The cost of a new Brisbane home air conditioning system is based on a number of different factors, including:

  • The type of system being installed: ducted systems are more expensive than split systems because they usually cater for larger properties
  • The amount of space being cooled: the more rooms/space you want to cool, the bigger the air conditioner, which increases the price.
  • The brand of the air conditioner: premium brands cost more money, but they’re more efficient and durable
  • The energy rating of the air conditioner: you’ll pay more for split systems that have a good energy rating, but you’ll save on electricity bills over the long run.
  • The amount of piping and cable needed: some properties (for example two storey homes) will need more refrigeration piping and electrical cable, which will add a little extra to the cost.
  • The amount of ducting needed (for ducted air conditioners): again, larger properties will require more ducting, which adds to the cost.
  • Whether the switchboard needs to be upgraded: if the electrical switchboard needs to be upgraded, this adds to the price.

Because there are so many factors involved in air conditioning, the cost can range anywhere between $750 to $20,000 plus.

How much does air conditioning cost to run?

An average modern air conditioner costs between $0.25 to $0.95 per hour to run on cooling mode, depending on the size of the room.1

What type of air conditioner do I need?

As with the price of air conditioning, the ideal system is determined by a number of different factors:

  • The amount of space being cooled: if you’re just wanting to cool one or two rooms, a split system (or multi-split system) is the cheaper and more efficient option. If you’d like a system that cools three or more rooms, and that can be managed from a single controller, a ducted system is the better choice.
  • The amount of control you’d like: modern air conditioners have smart capability, which means they’re able to be controlled from personal devices such as phones, tablets, and laptops.
  • Energy efficiency: air conditioners with a good energy star rating tend to be a little more expensive. But you’ll be recouping some of the high cost with reduced power bills.
  • The noise of the system: if you prefer quieter air conditioners, the air conditioning installer will likely recommend a quieter brand.
  • The look of the system: some people don’t like the look of wall-mounted split systems, and might prefer to opt for a discreet ducted system instead.

What are the benefits of air conditioning?

  • Improved sleep—good quality sleep is critical to our health. An air conditioner can easily regulate the temperature to help you sleep better.
  • Reduces the risk of dehydration and heatstroke—the Australian climate can be punishing in summer, and air conditioners can help us to stave off dehydration and heatstroke.
  • Air purification—air conditioners use advanced air filters to purify the air that you breathe, which alleviates hayfever, asthma, and leads to better health.
  • Better home security—windows must stay closed while air conditioning is on, which naturally improves home security.
  • Fewer insects—with the windows closed, fewers mozzies and flies will be able to get in.

Benefits of ducted air conditioning

  • Ducted air conditioners are hidden away in the ceiling and garden, keeping your home pristine.
  • Ducted systems are more energy-efficient for bigger properties.
  • Many modern ducted systems are super quiet—you won’t know they’re there.
  • Ducted systems offer a high level of control, particularly if you have smart features enabled.
  • A ducted air conditioner can increase the value of your home.

Benefits of split system air conditioning

  • Split systems are much cheaper than ducted systems, and are quick to install
  • Some modern split systems can be extremely quiet.
  • Split systems are easy to maintain. You’ll just need to clean the filters every 1-2 months, to keep air quality high.


What is reverse cycle air conditioning?

Reverse cycle air conditioning allows you to both cool and heat your home. Reverse cycle air conditioning is a great alternative to a heater, even for Brisbane’s milder winters.


What is inverter technology?

Modern air conditioners use inverter technology, which allows the system to control the speed of the compressor. For older systems, the compressor only has two modes: on and off. This means that it has to run at full speed until the set temperature is achieved, before turning off again—an inefficient way of doing things. Inverters allow the compressor to run at the exact speed needed to regulate the temperature, without having to exert itself.

Inverters have allowed air conditioning systems to become around 30% more efficient.
