A split system air conditioner unit typically costs from around $700 to $3,000+, depending on its size, efficiency, features and brand.

Online prices can be confusing. Some units cost a few hundred dollars, while others run into the thousands, even when they look similar. The main differences are capacity, energy efficiency, build quality and controls. For single-room cooling and heating, wall-mounted split system air conditioners are a common option.

This guide covers the cost of split system air conditioning units only. Installation is quoted separately by installers and not included here.

Split System Cost by Capacity

One of the biggest factors affecting split system air conditioner prices is capacity.

Air conditioner capacity is measured in kilowatts (kW). Generally, higher-capacity systems cost more because they are designed to condition larger spaces.

The table below provides a general guide to common split system sizes, suitable room sizes and relative price positioning.

Capacity Typical room size* Best suited to
2.5 kW Up to about 20 sqm Lower end of the range Bedrooms, home offices, small studies
3.5 kW About 20 to 30 sqm Low to mid range Larger bedrooms, small lounge rooms
5.0 kW About 30 to 45 sqm Mid-range Open-plan living areas, family rooms
7.1 kW About 45 to 60 sqm Upper mid-range Large living areas, combined living and dining
8.5 kW and above 60 sqm plus Top of the range Large open-plan spaces, high ceilings, western sun

*Room size is a general guide only. The right air conditioner size can also depend on factors including insulation, ceiling height, window size, room orientation, local climate and the number of people using the space.

These figures are intended as general guidance only and are not GENERAL Australia recommended retail prices. Actual air conditioner prices are determined by individual retailers and stockists.

It is also important to remember that air conditioner prices do not increase at exactly the same rate as capacity. Moving up one capacity size may not result in a proportionally large increase in purchase price.

However, choosing an air conditioner that is too small for the space may affect comfort and performance.

For a better size estimate, use our Air Conditioner Room Size Guide. This puts the air conditioning split system cost in context.

What Affects Air Conditioner Cost

Two split system air conditioners with the same capacity can have very different prices.

This is because air conditioner cost is influenced by more than just the size of the system. Features, energy efficiency, technology and functionality can all affect the purchase price.

A higher star rating under the Zoned Energy Rating Label (ZERL) usually means stronger efficiency, which can affect running costs. Reverse cycle models also cost more than cooling-only units because they provide both cooling and heating from one system.

Inverter performance is another factor. A better inverter can adjust output more smoothly, helping the room stay comfortable without the unit constantly switching on and off.

Filtration and air-quality features can also increase air conditioner cost. These features may help capture dust, reduce odours or improve indoor air quality, depending on the model.

Smart controls, app access and sensor features such as human sensor control add convenience. They make it easier to manage comfort without adjusting the unit manually every time.

Warranty length matters too. A longer warranty gives clearer protection and more confidence in the product.

How Much is a Split System from GENERAL?

So, how much is a split system from GENERAL? GENERAL sits in the quality end of the market, with pricing set by authorised retailers and installers at the point of sale rather than by a fixed public RRP.

The practical way to get a figure is to work out the capacity your room needs, then ask a stockist for a price on the right model. GENERAL’s Lifestyle range wall-mounted split systems are a cost-effective wall-mounted option, available in cooling-only and reverse-cycle models across capacities from 2.50 kW cooling up to 9.50 kW cooling.

Features include Economy Mode, Human Sensor, Powerful Mode, Low Noise Mode, Weekly Timer, Apple-Catechin Filter, Long-Life Ion Deodorisation Filter and inverter technologies such as i-PAM and V-PAM.

Cheaper Unit or Lower Running Cost

The purchase price of an air conditioner is only one part of the cost. A cheaper unit may look better upfront, but it may use more power over the years you own it.

The ZERL helps you compare estimated annual energy use between models of the same capacity. It also shows performance across hot, average and cold climate zones, which matters because air conditioners work differently depending on where you live.

A more efficient unit can cost more at the start but still be the better long-term choice if it uses less energy over time. That is why it is worth comparing both the unit price and efficiency before deciding.

FAQs

What is the average cost of split system air conditioning in Australia?

Split system air conditioner prices in Australia can range from around $700 for smaller, basic models to $3,000 or more for larger or feature-rich systems.

The typical split system cost of a household 3.5 kW unit usually sits in the low to mid-range of the market. However, the final price depends on factors including capacity, energy efficiency, features, brand and retailer pricing.

Installation costs are additional and are usually quoted separately by an installer.

Why does the price of an air conditioner vary between models?

The price of air conditioner models varies mainly because of efficiency rating and whether the unit is cooling-only or reverse cycle. Inverter performance, air filtration, smart controls and warranty length can also change what you pay.

How much does aircon cost to run?

Aircon running cost depends on capacity, star rating, climate zone and hours of use. The Zoned Energy Rating Label (ZERL) gives an estimated annual energy use figure you can compare between models. For the full explanation, read about Energy-efficient Split Systems and Running Costs.

Does a bigger split system always cost more?

Yes, unit price usually rises with capacity. But bigger is not always better. An oversized unit costs more to buy and may cycle inefficiently, so sizing the system to the room is the better approach. Use our Air Conditioner Room Size Guide to narrow it down.

Getting an Accurate Split System Price

Your air conditioner cost price depends on the capacity required, the model selected and the features and energy efficiency you choose.

A stockist can confirm the current price on a specific model. The installer should quote installation separately, as site access, electrical work and placement can change the final installed cost.
