Thinking about buying a new air conditioner? If you live in Canberra, it’s a smart move. With scorching summers and freezing winters, a reliable system isn’t just a luxury - it’s a year-round necessity. But with so many options out there, it’s easy to feel overwhelmed. This guide walks you through what to consider before proceeding, helping you choose the right unit for your home, climate, and budget. 

Canberra gets really hot… and really cold

Canberra isn’t just hot in summer - it’s freezing in winter too. With summer highs soaring into the 30s and frosty mornings in the minus range, temperature extremes are part of life here. Many older homes still rely on outdated heaters or fans that struggle to cope. So while you might be chasing warmth now, it pays to think ahead and invest in a system that can handle both seasons.

It’s hard to stay comfy all year

Winter is creeping in, and if your current system’s already struggling, it’s only going to get worse. Then summer hits, and you're back to tossing and turning through hot, restless nights. It’s frustrating. Your home should be your comfort zone, not a battle with the weather. But buying a new air conditioner can feel overwhelming. With so many types, features, and price tags on the market, how do you know what’s actually right for your home? What if you choose the wrong one, waste your money, and still end up uncomfortable?

Here’s what you need to know before you buy

Buying an air conditioner doesn’t have to be stressful. With a bit of guidance, you can find the perfect unit that keeps your home comfortable through all seasons - and doesn’t chew through your power bill. Here are some practical considerations to keep in mind.

1. Choose the right size for your space

When it comes to air conditioning, bigger isn’t always better. A unit that’s too powerful will cycle on and off too quickly, wasting energy. Too small, and it’ll run constantly without cooling or heating effectively. 

The best approach? Use a sizing guide or speak with a licensed technician who can recommend the right capacity based on your room size and layout.

2. Think about energy use

A more efficient unit might cost more upfront, but it can save you hundreds over time. Look for the star rating - more stars mean better energy performance. And in a city like Canberra where you’re using your system all year, energy efficiency really counts.

3. Know the types of air conditioners

Not all air conditioners work the same way, and the right type depends on your home’s layout, your budget, and how often you plan to use it. 

  • Split systems are the most popular choice for heating or cooling a single room or open-plan area. They include an indoor wall-mounted unit and an outdoor compressor. They’re relatively affordable to install, easy to maintain, and ideal if you want to control the temperature in just one or two spaces. 
  • Ducted systems are designed to heat or cool your entire home through a network of ducts and vents. While the upfront cost is higher, they offer seamless climate control, hidden components, and zoned settings - so you can adjust different areas of the house individually. A great option for larger homes or growing families. 
  • Portable air conditioners are the budget-friendly and flexible option. They’re compact and can be moved from room to room, but they typically don’t perform as well as permanent systems. Best for short-term solutions, renters, or when installing a fixed system isn’t possible. 

Before you decide, think about how many rooms you need to heat or cool, how often you'll use the unit, and whether your needs might change in the future.

4. Check for extras like installation and warranty

Some deals look cheap, until you realise installation isn’t included. Always ask if the price covers setup, and make sure there’s a solid warranty in place. A reliable installer should also offer support if anything goes wrong after the job’s done.

5. Local tip: Canberra weather requires a reverse cycle function

Canberra’s climate swings from scorching summers to icy winters, so it makes sense to choose an air conditioner that can do both. Reverse cycle air conditioning isn’t a type of unit, but a feature that lets your system switch between heating and cooling as needed.

You’ll find reverse cycle technology in split systems, ducted systems, and even some portable units. It works by reversing the refrigeration cycle – cooling your home in summer and pulling in warmth during winter. It’s an efficient, space-saving way to stay comfortable year-round, and a smart choice for Canberra homes.
