A reverse cycle air conditioner, also known as a heat pump, refers to a refrigeration cycle that can provide both heating and cooling solutions. This is done by reversing the refrigeration cycle so that the system can heat in winter and cool in summer.
During the heating season, the refrigerant absorbs heat from the outside air and transfers it to the inside of your home. During the cooling season, the refrigerant absorbs heat from the inside of your home and transfers it to the outside air. The entire system is efficient, adaptable, and flexible.

Heating and cooling a house makes up about 50% of the average Victorian household’s energy use, having an energy efficient system helps you reduce energy costs and greenhouse gas emissions.

In this article, we will discuss the basics of reverse cycle air conditioners, including how they work, what features and types they have.

How does a reverse cycle air conditioner work?

The mechanism of a reverse cycle air conditioner is so simple to understand. Think of like a heat sponge. In the winter, it slurps up even the tiniest bit of heat from outside and release it into your home. Then, in summer, it grabs that stuffy indoor heat and throws it outside, leaving you in a cool atmosphere.
So, how does this magic happen? It’s all about this thing called a heat pump. It’s like a two-way system of getting out for heat. It has two coils – one inside, one outside – and a special fluid called refrigerant that absorbs heat and release it.

Cooling Mode:

• The inside coil gets super cold and gobbles up heat from your indoor air.
• The refrigerant, now carrying all that heat, zips over to the outside coil…whoosh! It lets go of the heat and blows it outside.

Heating Mode:

• Just think of it as running the whole thing backwards! The outside coil snatches up any warmth lurking in the outside air (even if it feels chilly!).
• That warm refrigerant head inside, releases the heat into your home, and gets ready to find more warmth outside.

Reverse cycle is the more energy-saving and versatile than traditional old AC. It transfers heat around instead of making it from burning electricity, kind of like recycling warmth or coolness. That means less energy consumption and lower bills get to feel you calmer.

Types of reverse cycle air conditioners

There are three types of reverse-cycle systems available: split systems, ducted (whole of house) systems and multi-head units.

01. Split Systems: These are the most common type of reverse-cycle system. They consist of a single outdoor compressor unit connected to a single indoor unit, typically mounted high on a wall. Split systems are ideal for efficiently heating or cooling a specific room or open-plan living area. For single rooms, a split system is a better choice.

02. Ducted (Whole-of-House) Systems: As the name suggests, a ducted system provides heating and cooling throughout your entire home. It has a central outdoor unit connected to a network of ducts hidden in your ceiling or floor. Air is distributed into each room through discreet vents, allowing you to control the temperature of the whole house. For whole home heating and cooling, then a reverse cycle ducted air conditioner is a better choice.

03. Multi-Head Units: These versatile systems offer a middle ground between split and ducted systems. A single outdoor compressor unit powers multiple indoor units installed in different rooms. This allows you to independently heat or cool various zones within your home for customized comfort.

Why should I replace my current heating system with a reverse cycle system?

Warmth in winter, refreshing chilly coolness in summer, and savings on your energy bills. Sound impossible? Not with reverse cycle systems! Here’s the deal:

  • Electric Heaters: Cheap to Buy, Expensive to Run.
    They might be tempting, but those portable electric heaters are energy vampires. Ditch them, and you’ll see instant savings.
  • The Gas Trap. Gas heating used to be the affordable choice. But now, with renewable energy powering our grid and super-efficient reverse cycle tech, gas is outdated. Reverse cycle systems heat your home just as well (if not better!) without the pollution of gas systems.
  • The Reverse Cycle Advantage: Heating, Cooling, and Savings! Not only can a reverse cycle unit keep you warm, but it also flips into AC mode for those scorching summer days. Think of it as the ultimate comfort machine for any season.

Think again! Getting rid of your gas connection costs around $800, but you can include this in your loan. Youll also save around $350 each year by not having a gas supply charge. Plus, youll be saying goodbye to gas infrastructure on your property for good.
