What is Reverse Cycle Air Conditioning?
A reverse cycle air conditioning system is a versatile unit that provides both heating and cooling in your home. Unlike traditional air conditioners, which only cool the air, reverse cycle ACs can heat your home in winter while keeping it cool during summer. Therefore, they an energy-efficient solution for year-round comfort.
Victorians often ask, “Which air conditioning system is best?” The answer depends on your home size, layout, and needs. Ducted systems are perfect for whole-house climate control, offering even temperature distribution, while Multi Split ACs allow you to control individual rooms for flexibility and cost savings.
Additionally, modern reverse cycle ACs often include features like air purification and humidity control, which help reduce allergens and create a healthier indoor environment, something many homeowners in Melbourne are looking for.
Leading brands offering these features include Mitsubishi Electric, Hisense, Panasonic, Daikin, and Fujitsu, making it easier to enjoy comfort, cleaner air, and optimal humidity throughout the year.
How Do I Choose the Right Size Reverse Cycle Air Conditioner?

If you’re looking for an energy efficient AC in Victoria, choosing the right system can help cut running costs and improve comfort. The size of an air conditioner refers to its rated heating and cooling capacity, usually listed in kilowatts (kW). Reverse cycle ACs have both a heating and cooling size, which can be different.
Choosing the right size is crucial:
🏡 A system that is too small may struggle to heat or cool your home on the coldest or hottest days, taking longer to reach a comfortable temperature.
🏡 By contrast, an oversized system can cost more to purchase and run, may be less efficient, and can cause large temperature swings that reduce comfort.
🏡 Every household is unique, so the right size depends on your home layout, insulation, and energy needs.
What Should I Consider Before Installing a New Air Conditioning System?
Before investing in a new heating and cooling system, think about the efficiency and characteristics of your home:
How efficient is my home?
⚡️ Check for draughts around windows, doors, and vents. Sealing these can lower energy costs.
⚡️ Inspect insulation in walls, floors, and ceilings. Proper insulation reduces heating and cooling requirements.
⚡️ Consider your house construction (brick, weatherboard, etc.), which affects energy needs.
How does my local climate affect my AC choice?
⛅️ Victorian homes often use more energy for heating than cooling, so look for units with higher heating efficiency.
⛅️ Use the zoned energy rating label to compare efficiency for your climate.
⛅️ Ask your installer which models suit your location.
How does my house orientation impact heating and cooling?
🏠 Consider sun exposure and shade; it can reduce or increase heating needs.
🏠 Large single-glazed windows can cause heat loss in winter or heat gain in summer.
What room factors should I consider?
1️⃣ Size: Length, width, and ceiling height. Rooms above 2.4 m need more energy.
2️⃣ Airflow: Important if the system will serve multiple rooms.
3️⃣ Room priorities: Focus on primary living spaces like living rooms, family rooms, lounges, and open-plan areas. Covering too many or too few rooms can impact cost and comfort.
Are energy-efficient air conditioning systems expensive to run in Victoria?
Modern reverse cycle systems are among the most popular energy-efficient AC options in Victoria for homeowners. In fact, the costs depend on the type of system, its energy rating, and how it’s used.
Moreover, energy-efficient reverse cycle ACs, like Glower’s Ducted, Split and Multi Split systems, are designed to keep running costs low while maintaining comfort. These systems use advanced compressors and smart temperature controls to reduce electricity usage without compromising performance.
For example, a typical energy-efficient AC in a Victorian home may use between 1 to 3 kWh per hour, depending on the size of the unit and your usage habits. By contrast, choosing a high EER (Energy Efficiency Ratio) system and using timers or smart controls, homeowners can significantly reduce running costs.
Many Victorian households also benefit from government incentives and rebates for energy-efficient systems, further improving the value of upgrading to a modern AC.
