When Melbourne’s summer heat kicks in, air conditioning isn’t a luxury — it’s a necessity. But with electricity prices on the rise, many homeowners are wondering: Which air conditioning system is the most cost-efficient to run?

In this guide, Melbourne Aircon Specialist breaks down the running costs of different air conditioning types, helping you choose a system that keeps your home comfortable without draining your wallet.

1. Factors That Affect Air Conditioner Running Costs

Before comparing systems, it’s important to understand what influences their operating expenses:

• Energy Efficiency Rating (EER & COP): Systems with higher ratings consume less electricity for the same cooling output.
• System Size: Oversized or undersized units waste power. Proper sizing ensures maximum efficiency.
• Electricity Tariffs: Victorian households pay an average of $0.25–$0.35 per kWh. This directly affects running costs.
• Climate and Usage: Frequent use during Melbourne’s humid summers naturally increases energy bills.
• Maintenance: Poorly serviced aircons work harder, consuming up to 30% more electricity.

2. Comparing Running Costs by System Type

Let’s look at how much different types of air conditioners cost to run per hour or per season in Victoria.

Quick Tip: Reverse-cycle split systems are the most energy-efficient option for both cooling and heating in Victoria — especially when paired with solar energy or rebates through the Victorian Energy Upgrades (VEU) Program.

3. The Cheapest Air Conditioning System to Run

Reverse-Cycle Split Systems take the crown for energy efficiency and running cost.
Why? They use electricity to transfer heat rather than generate it, offering 300–600% efficiency.

In simple terms — for every 1 kWh of electricity used, you get up to 6 kWh of heating or cooling output. That’s why modern VEU-approved systems are so popular among Victorian homeowners.

4. The Most Expensive Systems to Run

Gas Ducted Heating and older non-inverter ducted systems are typically the most expensive.
They rely on gas or high-energy compressors that consume far more power. Plus, they lack the zoning flexibility that allows you to cool only the rooms you’re using.

If you’re still using a ducted gas system, now’s the time to consider switching to an electric reverse-cycle ducted aircon — and claim rebates under the VEU Program.

5. How the VEU Program Helps You Save

The Victorian Energy Upgrades (VEU) Program rewards homeowners who replace inefficient gas or electric systems with energy-efficient models.

6. Tips to Reduce Your Air Conditioning Running Costs

Even the best systems need proper maintenance to perform efficiently. Follow these simple tips:

• Clean filters every 2–3 months
• Schedule a professional tune-up annually
• Seal doors and windows to prevent air leaks
• Use zoning to cool only occupied rooms
• Pair your system with solar panels for maximum savings
