During summer, the last thing you want is a sweaty, uncomfortable home. Air conditioners are the perfect way to keep your home nice and cool while you enjoy the sunshine and maybe an ice cream or two. Installing an air conditioner is a tricky process that should be done by a professional, so you can cool down faster. 

An average hourly rate for air conditioner installation in Australia is $80. This, of course, depends on the job they are tasked to complete. It costs, on average, $5,000 to install an air conditioner into your home. This price varies depending on the size of the house, how many windows you have and the type of air conditioner you’re planning to install.

Whether you need to install a split system, ducted, portable unit or window units, or even repair the air conditioner that you currently have, the prices may increase or decrease. This guide will be the first step to you cooling your home down, just in time for summer!

Do I need to hire an aircon installer?

There are many different types of air conditioners out there, and sometimes you may think you can install it yourself. However, a licensed electrician is the safest and legal option for those who want to install an air conditioner into their home. Of course, a portable air conditioner can be installed by yourself, but it’s best to hire a professional for the following installations and repairs:

  • Ducted system

  • Window units

  • Central cooling

  • Split system

  • Pipe repairs

In Australia, the Australian Refrigerator Council requires you to hire a licensed electrician or plumber to install or repair an air conditioner into a building. They must hold a full Refrigeration & Air Conditioning licence or a restricted license; the latter only allows them to install split system aircons. 

What are some questions to ask an electrician?

Before you hire an electrician to install or repair an air conditioner in your home, there are a few questions that you definitely need to ask, to make sure you’re getting the best possible professional for the job. 

  • Do they have a full Refrigeration & Air Conditioning licence?

  • How many tradies will be present whilst the installation or repair takes place?

  • Do they have insurance?

  • What services do they provide?

  • Do I need a permit to have this air conditioner?

  • What is included in their service fees?

Before you hire the professional, be sure that all tradies present in your home are licensed. Some tradies are certified air conditioner installers, some may be plumbers with certified training in installation and repair, and some have training but no license. Be sure to confirm these before you hire, as your installation process needs to be legal and at the best quality. 

Air conditioner installation and repair prices for different types of services

Prices for air conditioner installation can vary from service to service. Some electricians are paid by the hour, but others charge based on the air conditioner brand, type, wattage and any other services added to the original job requested.

FAQs about air conditioner installation services

Some ducted units require water to operate properly as they use water to cool the condenser.
Ducted and central air conditioners are a real energy hog. A window unit AC uses 500 to 1440 watts, while a 2.5-ton central system uses about 3500 watts. A floor fan uses only 100 watts on the highest speed, and ceiling fans use only 15 to 90 watts depending on speed and size.
Generally speaking in summer thermostats should be set 24°C–26°C. Every 1°C lower can increase running costs by up to 15%.
It depends on the type of air conditioner you’re going to install. Typically, it takes a few hours to a whole day for an electrician to install an air conditioner.
It really depends on how often you maintain your aircon. The average life expectancy of an air conditioner is well over 10 years. Be sure to get your aircon checked up and tuned to increase its expectancy.
In order to keep your aircon at its fullest capacity, it’s safest to service it once a year. This allows the piping to stay clean, manages any leaks and recalibrate the refrigeration settings.
