Buying the right air conditioner for your home can be confusing. With so many different options, features and sizes, it’s hard to choose the right one. However, it is important to make the right decision, as a unit that is too small or too large for your room will lead to inefficient operation. 

Throughout the year, it’s important to spend the time to select the correct residential air conditioning system so you can have the optimum temperature in your home as efficiently as possible.

In this guide, we will run through some of our most important tips on how to choose an air conditioner that will prove a cost-effective and efficient solution for your home.

How to Choose an Air Conditioner For Your Home

Upgrading your home’s air conditioner involves analysing various factors, from the layout of your home to any major heat sources and the type of units that will be most suitable.

Measure your home’s size and layout

Before speaking to an air conditioning specialist, it’s a good idea to know the number and size of rooms that require cooling; the direction your home is facing, whether it’s the east, west, etc, and whether or not your ceiling has insulation. These are all important factors when picking the right unit.

Choose a trusted and awarded brand

Look for air conditioning units that have a stamp of approval. The Reader’s Digest Most Trusted Brand is based on consumer opinions on which brand is most trusted. Fujitsu General has been voted the Most Trusted air conditioning brand from 2018-2022 and was awarded Highly Commended from 2023-2025. In 2024, Fujitsu General was also rated Finder’s Most Loved and Best Value Brand for a third year in a row. Now, in 2025, Fujitsu has proudly won the productreview.com.au Best Appliance Brands award.

Consult with a specialist

Make sure your system is installed by an appropriately licensed technician, as the refrigerants can be harmful to you and the environment. We have a list of Fujitsu Authorised Partners where you can request a quote by entering your postcode. It’s also important that the installer has an ARCtick licence.

After installation, the installer is required to provide a demonstration, showing how to correctly use the air conditioning unit and controller. This will help you understand the optimal temperature settings, how to set up weekly timers to cool the home when required, and how to change reverse cycle units from cooling to heating mode at the change of seasons.

Factor in energy efficiency for cost savings

With the rising cost of living, energy efficiency is a priority concern for many buyers of air conditioning systems, particularly in the approach to the summer months. Fujitsu General units incorporate a range of energy-saving measures, from motion sensors to detect when a room is occupied, to hybrid heat exchangers to optimise efficiency and Economy modes that limit fan speeds as much as possible while maintaining the desired temperature.

Each unit also has a star rating for heating and cooling modes. The better the star rating, the more energy efficient the unit performs. 

Explore units with smart features

Smart air conditioners are those which offer a higher level of compatibility and connectivity for improved comfort and flexibility. Some of our units are equipped with anywAiR technology. The Lifestyle Next range is equipped with smart climate control functionality. Using the myanywAiR Next app on your smart device,  you can program a range of functionalities remotely, including timers and schedules.

Use the Fujitsu Assist Product Selector Tool

The Fujitsu Assist Product Selector Tool is an ideal place to start exploring different air conditioners for your home. Using the tool, you can compare features and functionalities of different units and find recommendations for your home based on the size and layout of your home.

Invest in a Fujitsu General for a Comfortable Home

Selecting the right air conditioner for your home shouldn’t be confusing. Knowing how to choose an air conditioner size that is right for your home involves consideration of a range of factors, including room sizes, home layouts and unit types. Engaging a specialist is the easiest way to find out what air conditioning units will be most suitable for your home. However, you can also do your research using resources such as the Fujitsu Assist Product Selector Tool.
