An Air Conditioning Installation Cost Guide for Your Home

An Air Conditioning Installation Cost Guide for Your Home

The type of unit and the time is taken to install it will affect your overall air conditioning installation cost. However, as a guideline, plan on spending $2,400 to $5,400 and up for a ducted system, and between about $600 to $749 for a split system. The installation cost should be considered along with the actual purchase cost and the system’s running costs.

The three most common types of air conditioning system available are:


These cool just one room due to their limited output, although as they can be used anywhere, you have a power outlet, they are versatile.

Split system:

The coverage of these affordable systems is on a per room basis, and you can read more about how they work here. They use an external condenser and an internal head unit and are the most common type in use today.

Ducted system: 

It will cost you more to buy and install a ducted system, although as they are fitted into the wall cavity and ceiling of your home, your entire home is effectively cooled or heated. 

Several factors determine the size of the air conditioning unit you’ll need:

Home size: 

A larger capacity A/C system is needed for a larger home. And it may cost you more if you live in a multi-story home, as you may need several units to handle different zones.

Ceiling height and number of windows:

A more powerful unit may be needed if you have high ceilings, and also if you have a lot of windows, as up to 40 percent of the heat lost in your home escapes through the windows.

Your technician should be licensed.

Unless your air conditioner company only installs split system units, he will need to have a Refrigerating and A/C license, as required by the ARC (Australian Refrigeration Council)

Keep in mind your final air conditioning installation cost, and quotes are affected by various factors:

Size and type of unit

Amount of cable ducting, connecting cable, and refrigeration piping required.

Meter board upgrade, if applicable.

A small portable unit may cost you around $500, or you should expect to spend around $900 on a new slit system. However, it’s also possible to pay several thousand dollars or more. The unit’s kilowatt capacity also determines the price; a portable unit may be more cost-effective if you live in a studio apartment or other smaller space.

The cost of installation

The number of units being installed can affect this cost, as can the type of unit, how easy it is to install it in your home, and even where in the country you live. In general, a commercial system installation will cost you between $80 and $140 per hour, plus GST, while for installation in your home, expect to pay between $60 to $110 plus GMT.

Expect to pay the following to install a wall hanging split system:

2.5kw – 3.5kw inverter system $600

5kw – 6kw inverter system $650

7kw – 8kw inverter system $700

9kw- 9.9kw inverter system $750

8.0kw ducted reverse cycle Samsung air conditioning unit $5400

Getting a quote from several different companies is always recommended before having any installation work. A few different quotes will give you an idea of how much the work typically costs and let you know what those rates currently are. Ensure you understand the charges and exactly what is included, and of course, your chosen technician should always be insured and licensed. It’s always a good idea to ask the heating and cooling company to give you some referrals from previous customers.

All prices quoted above should be used as a guide only and can vary over time and between localities, although at the time this was written, the figures were accurate.
