How to choose an air conditioner? This is one of the most frequently asked questions by homeowners, because it’s not just about cooling in summer or keeping warm in winter, but about investing wisely in year-round comfort, energy savings and climate efficiency.
Whether you’re upgrading your old unit or installing one for the first time, the right choice can make all the difference in your home’s performance and your power bills.
In this guide, we’ll walk you through how to choose an air conditioner that suits your space, your climate, and your energy goals.
1. How Does the Weather Affect Your Needs?
Victoria’s climate can swing dramatically from scorching summer days to chilly winter nights. That’s why reverse cycle air conditioners are a top pick for most Victorian homes. They offer both cooling and heating in one system, giving you maximum flexibility without doubling your energy use.
For regions like Melbourne, Geelong, or Ballarat, where winters are colder, heating performance is just as important as cooling power.
2. Why is Energy Efficiency Important?
With rising electricity costs, energy efficiency is more important than ever. Energy-efficient air conditioners don’t just reduce your power bill, they’re better for the environment.
Look for systems with High star ratings, Inverter technology and Zoning capabilities.
Efficient systems may cost more upfront, but they’ll pay off in lower power bills and may qualify for rebates.
3. Why the Capacity of Your Air Conditioner Matters?
Choosing the right size system is key. The larger your space, the more power you’ll need. Here’s a rough guide:
Installing a unit that’s too small means it will constantly overwork and underperform. Too large? You’ll waste energy and money.
4. How to Choose a Right Air Conditioner?
Although there is no universal solution, each system has different characteristics and is best adapted according to the space. These are the main ones:
Split System: Best for single rooms, easy to install, and highly efficient
Multi-Split: Connects multiple indoor units to one outdoor unit
Ducted System: Ideal for larger homes needing full-house climate control
Portable Units: Good for renters or short-term cooling
Window Units: Affordable for small rooms, but limited features
Some of the top brands in Australia (2025 update) are: Mitsubishi Heavy Industries, Daikin, and Panasonic.
5. What Rebates are Available in Victoria?
The Government offers energy upgrade incentives and rebates in Victoria that can save you hundreds when installing a new system.
- Victorian Energy Upgrades: Discounts applied at point-of-sale for energy-efficient systems
- Solar Victoria Rebates: Up to $1,000 for heating and cooling upgrades
