Coming into summer, many Australians are looking at buying a new air-con, and with this comes questions – what size aircon do I need? How much power does an aircon use? What are the different types of aircon? With so many factors to consider, we’ve put together this handy blog to explain some of your aircon questions, so you can purchase your new air conditioner with confidence. What size aircon do I need? The size of the air conditioner you need depends on the size of the room you want to put it in. If you have a large, open plan space with high ceilings, this will require more energy to cool than if you’re just looking for an aircon to cool your small guest bedroom. Finding the right fit for your space The table on the right shows the approximate capacity of the air con you’ll need in relation to room size. Where you live and how hot it is also has an impact – for example people living in Cairns will need an aircon with a bigger capacity than those in Hobart. Room Size Near Capacity Small (up to 20m2) 2 – 2.5kW Mid-size (20–40m2) 2.5–5kW Large (40–60m2) 4–6kW Extra-large (60+m2) 5–9kW How much power does an aircon use? How much power your aircon uses largely depends on the type, wattage and star rating of the model you have. As mentioned before, where you live also has an impact on the energy it takes to power the aircon, along with how much time it’s on for. What are the different types of aircon? If you live in a warmer, tropical climate like Far North Queensland, a cooling-only air conditioner can be a practical and energy-efficient option for your home. Because these regions experience long periods of heat and humidity with minimal need for heating, focusing on cooling performance and moisture control is key. If space is limited, portable air conditioners such as window or wall types can be a convenient option for apartments, smaller rooms or rental properties. Compact and easy to install, these systems can also be practical if you plan on moving house in the future. It’s also worth considering models with air purification filters, inverter technology and modern refrigerants designed to improve efficiency and maintain consistent temperatures while reducing energy consumption. With so many factors to consider, buying the right aircon for your home can be tricky. Thankfully, the team at your Local Betta are here to help!
