The average air conditioner cost in Sydney sits between $2,000 to $8,000 (inc. unit and installation) but you can skew to either end of the range if you opt for a budget-friendly single-room unit or a more robust ducted system. Be sure to choose the right size unit for your space and keep in mind which rooms do or don’t need the help of an aircon during the hottest months.

Let’s face it, Sydney summers without A/C can be tough.

There’s only so many day trips you can organise to Bondi Beach before you realise you need a way to cool your home that’s more effective than a fan.

As the mercury starts to rise, it’s essential to have some type of AC in your home, and thankfully the range of options on the table mean there’s something for every household budget.

Extreme heat calls for more than a sea breeze, and installing an air conditioner that’s reliable and energy efficient can be just what you need to keep cool on those sweltering, scorching days.

But how much is a new A/C unit going to cost in Sydney?

Well, this comes down to the type of air con system you get and how large the system is. This still leaves plenty of variation between the cheapest unit and the most premium residential system, but we’ve got you covered.

That’s why we’re breaking air conditioner costs as well as key considerations for your Sydney home. Ready to make the right choice for your home and cool off? Let’s get into it.

Is getting an air conditioner worth it?

The answer to this question is a personal decision.

If you’ve struggled through Sydney’s hotter months, or ducked to the local Westfields just to enjoy a little A/C, then the answer is likely “yes”.

Going back a few years, many Australian homes were constructed without air conditioners. In Sydney in particular, where the climate isn’t just warm but humid, fans alone can’t always provide the levels of comfort you need – which has fuelled an explosion in A/C installation.

Keep in mind, an air con system does more than just cool things off. Here are a few other benefits that A/C can add to your home.

Asthma attack prevention

Running an aircon not only reduces humidity in your home, but it can also lower the amount of mold, mildew, and other airborne allergens such as pollen – all of which can cause asthma attacks.

A more secure home

Since you’ll be keeping your doors and windows closed when the AC is turned on, it becomes harder for someone to break in. We’re not saying that you shouldn’t get security services for your home, but this is just another reason to love A/C.

Improved air quality

Many modern air conditioners come with advanced filters that protect against pollutants, irritants and even small pests and parasites that can frustrate you and your pets.

Better sleep

Did you know people actually sleep better in colder conditions? We don’t need to tell you how important a good night’s sleep is to your general well-being, with a modern A/C unit helping you wake up feeling fresher and ready to take on the challenges of the day.

Keep your electronics cool

It’s not just your body that will thank you when the temperature drops, because the electronic gadgets and appliances in your house will work better in an air conditioned house, too. Electronics like computers, laptops, and TVs are prone to overheating, and that can damage their performance and efficiency.

What factors affect air conditioner cost in Sydney?

Alright, enough about the benefits of air con.

You’re here for prices, numbers and cold hard data and we’re going to give it to you.

For the most part, the price of A/C will come down to:

  • A/C system type
  • A/C system size

For example, a single room split-system unit will be more affordable than a whole house ducted system.

The more components a system has, the larger the system, the more costly it could be as well. Again, consider that a ducted system, which can include quite a bit of ductwork along with the compressor and supporting parts, will cost more to install compared to a split system aircon that takes up minimal space in the room(s) you choose.

The good news is that air cons come in all different sizes and cost brackets, so you’ll be able to cool off without overheating your budget.

How much does an air conditioner system cost?

We’ve summarised the average cost for some of the most popular aircon types in Sydney to help you budget for this home upgrade.

PLEASE NOTE: Installation is often charged separately and can cost on average $60 to $110 per hour.

Air Conditioner Type Average Cost
Portable (small space) $200 to $400
Portable (large space) $600 to $1,400
Ducted (small home) $4,000 to $7,000
Ducted (large one-storey home) $7,000 to $10,000
Ducted (two-storey home) $9,000 to $15,000
Split System $1,700 to $5,500

HUNTERCON TIP: The best way to know the cost for your home is to call a professional installation expert. They will be able to help you determine the best system type and size to most efficiently cool your home. In fact, undersizing your unit to save on upfront costs can actually cause it to work harder to cool your home, impacting your energy bill and putting extra wear and tear on the aircon itself.

What is the cost of running air conditioners for cooling?

Now that we’ve given you enough reasons to get excited about buying an aircon, let’s look at what it will cost you.

In the table below, we’ve broken out the average cost per hour for a variety of different room cooling methods. You’ll notice that the cost of running a fan is the cheapest, but the cooling and coverage is nowhere near to what you can get with even the smallest aircon. In contrast, you’ll pay for the convenience of a whole-house ducted system, but this could be a more efficient (and comfortable) option overall.

Air Conditioner Type and Room Average Cost per Hour
Reverse Cycle – 20 m2 room $0.25 – $0.35
Reverse Cycle – 36 m2 room $0.36 – $0.70
Reverse Cycle – 50 m2 room $0.70 – $0.96
Portable Refrigeration Device (any room size) $0.45 – $0.55
Variable Speed Fan (any room size) $0.02 – $0.05
Ducted Reverse Cycle (whole house) $2.45 – $3.45

How much does it cost to use an air conditioner for heating?

Some aircon systems can also be used to warm spaces, which makes them more versatile in the cooler months when you’d rather heat things up.

In this table, we’re comparing some of the different heating costs by type to give you a better idea of the investment.

PLEASE NOTE: Some of the pricier options are actually less efficient and less effective at warming larger spaces.

Heater Type Average Cost per Hour
Air Conditioner $0.13 – $0.36
Electric Radiant Heater $0.35 – $0.40
Electric Panel Heater $0.40 – $0.45
Gas Heater $0.43 – $0.51
Ducted Heat (whole house) $1.45 – $2.12

4 ways to keep your air conditioner running efficiently

By now you can see that modern air conditioners are affordable and practical for all household budgets, but that doesn’t mean you can’t save even further. Here are a few of our favourite ways to help you minimise the costs of running your air con once you have it installed.

#1 – Maintain a consistent temperature

One of the best ways to reduce the impact of air cons on your electricity bills is to keep a consistent temperature throughout the day. While this might sound counterintuitive, keeping your air conditioner warmer in summer and colder in winter can ensure that it isn’t working too hard, resulting in a hike in your energy consumption. The best temperatures to go by are 24°C in summer and around 19°C in winter.

#2 – Add some shade

While it can be tempting to take advantage of both your air conditioner and the cross breeze at the same time, it can wreak havoc on the efficiency of your air con. This can have a negative impact on your electricity bills.

The best way to keep your bill under control is to close the doors and curtains and turn off any lights that are not being used. This will reduce the heat absorption in your house, making it easier for your air cons to operate. Likewise, using the same practice in winters can trap in more heat, making it friendlier for your energy bills.

#3 – Perform regular maintenance

One of the most important things for the efficiency and performance of your air conditioner is to have it maintained by a professional at regular intervals. Ensure the filter is replaced as needed or cleaned regularly, usually quarterly. Dust the vents and any exterior components. Just like any other appliance, keeping your air conditioner well maintained will help reduce the overall cost of running it.

#4 – Insulate your home

This option is a little difficult if you’re renting. However, if you have your own home, then this is something you should definitely explore. Adequate insulation of your home will reduce how much effort your air con will need to put in to cool or heat an area. If you’re in the process of building your home then it’ll be easier to insulate it correctly. Alternatively, you can have adequate insulation installed even in an existing property.
