What Is a Reverse Cycle Air Conditioner? Everything You Need to Know

If you're buying an air conditioner in Australia, you've probably come across the term 'reverse cycle' — but what does it actually mean? This guide explains everything clearly so you can make a confident purchase decision.

What Does Reverse Cycle Mean?

A reverse cycle air conditioner (also called a heat pump) can both cool and heat your home. In summer, it works like a standard air conditioner — extracting heat from inside and releasing it outside. In winter, it reverses the process — extracting warmth from the outdoor air (even when it's cold) and moving it inside to heat your space.

This is different from a cooling-only air conditioner, which can only run in cooling mode and cannot be used for heating.

How Efficient Is Reverse Cycle Heating?

Reverse cycle heating is one of the most efficient forms of heating available. For every 1 kW of electricity consumed, a modern reverse cycle unit produces 3–6 kW of heating energy. This is because it moves heat rather than generating it, unlike electric radiant heaters or gas heaters that convert fuel to heat directly.

Can a Reverse Cycle Unit Work in Cold Weather?

Yes — modern units can extract heat from outdoor air even when temperatures drop below 0°C. Most Australian reverse cycle units are rated to operate down to -15°C ambient. For Sydney's climate, this is never a concern.

Split System vs Ducted Reverse Cycle

• Split system — consists of one indoor wall unit and one outdoor compressor. Best for single rooms or open-plan areas. Easier and cheaper to install.
• Ducted system — one central outdoor unit connected to ducts throughout the home. Heats and cools every room. Higher upfront cost but more seamless in appearance.

What to Look For When Buying

• Capacity (kW) — must suit the room size. As a rough guide, allow 0.1 kW per square metre plus 25% for direct sun.
• Energy star rating — two separate ratings (cooling and heating). More stars = lower running costs.
• Inverter technology — all modern units feature this; it adjusts compressor speed for more efficient operation.
• WiFi control — control from your phone with many current models.
