Guide to Reverse Cycle Air Conditioning Cost in Australia

Before purchasing a new air conditioning system, it’s important to consider not just the upfront price, but also the potential ongoing costs of using a particular system. Being aware of costs and how they can be affected by available functions, installation, running, maintenance, and your local climate can help you choose the right system for your home. 

The popularity of reverse cycle air conditioners in Australia in recent years hasn’t been just from their efficiency, but also their affordability. This article will walk you through the potential costs of this system and what can impact them. Overall, we’ll help you make an informed decision when purchasing your reverse cycle air conditioner.

What is a Reverse Cycle Air Conditioner? 

A reverse cycle air conditioner is a type of air conditioner that can both heat and cool a space within your home. It comes as both multi-split and singular unit systems to adapt to any home’s structure and room numbers.

Also known as heat pump technology, reverse cycle air conditioning reverses the refrigerant cycle to provide both heating and cooling from the same unit. This helps prevent the need to use or install fans and separate heaters within your home.  

Costs Associated with Reverse Cycle Air Conditioners

As with any type of air conditioner, a reverse cycle air conditioner will have costs beyond the purchase of the unit itself. Being aware of the potential costs can help you budget accordingly and find the most cost-effective unit for your home.

When you’re thinking about buying a reverse cycle air conditioner, you should consider these major factors:

  • Running costs
  • Installation procedure
  • Maintenance needs
  • The cost of replacing or repairing an old air conditioner,
  • How your local climate will impact your air conditioner usage  

Running Costs 

The running costs for a reverse cycle air conditioner are determined by several different factors, all of which should be considered before purchase.

  • The specific type of reverse cycle air conditioner you have: Ducted, split system and multi-split system air conditioners can all be reverse cycle air conditioners. As they each operate in different ways and have different use cases, the price of running them is different
  • The size of the space being heated/cooled: Smaller spaces and rooms require less heating and cooling than larger spaces and rooms, which in turn affects your electricity bills. The size of the space being heated or cooled can also determine which type of reverse cycle air conditioner may be best for you. Generally, split system air conditioners can be good for heating and cooling a particular room or space with precision, while ducted air conditioners allow for whole-house coverage.
  • Energy efficiency: Australian air conditioners operate on a star rating system for efficiency. An air conditioning system with a three-star energy efficiency rating than one with a two-star rating, affecting the running cost. 
  • Heating vs cooling usage: Generally speaking, using the cooling function of your reverse cycle air conditioner is more expensive per hour than the heating function. 

Installation

As with running costs, the cost to install a reverse cycle air conditioner will depend on the specific air con system you purchase. However, it can also be impacted by the amount of work needed to prepare your home for the new system and its functions.

  • Reverse cycle ducted air conditioners will generally cost more to install than either split system or multi-split system air conditioners. This is because installing a ducted system requires significant changes to your home and its structure, especially when adding ducts to multiple rooms. 
  • Reverse cycle split system air conditioners cost less to install than either ducted or multi-split systems, as they only have a single indoor and outdoor unit to install. 
  • Reverse cycle multi-split system air conditioners cost more than a single split-system air conditioner, but offer wider coverage of a home. Multi-split system air conditioners also offer considerable installation cost savings compared to ducted systems. However, the installation price can ultimately vary depending on the number of indoor units you want to install in your home. 

Maintenance

Regardless of the specific reverse cycle air conditioning system you have installed in your home, it’s important to keep up with its maintenance. This ensures that your system will keep running efficiently while also extending its lifespan, preventing any unexpected repair costs in the future.

Replacing Old Air Conditioning Systems

The cost to replace your old air conditioning system can vary considerably, based on your home’s existing air conditioning infrastructure and your desired upgrade path. While there may be a high initial cost, replacing an older air conditioner can be a cost-effective solution due to technological improvements and increased efficiency of newer models. 

If you’re thinking of replacing your old air conditioner, you can take advantage of the government rebates on offer in your state and save money. We also have our own rebates and promotions available to save you money.  

Local Climate

Your local climate will affect how you use your reverse cycle air conditioner, and in turn, impact your running costs. You will likely spend less money heating or cooling your home via air conditioning if you live in a mild climate area, compared to living in a climate with extreme heat and/or cold.

What Impacts the Cost of Running a Reverse Cycle Air Conditioning System in Your Home

Installing a reverse cycle air conditioner can be a valuable addition to ensure your climate comfort. Regardless of the type of air conditioner, there are multiple factors that will impact the running cost over time. 

Lifespan

Thanks to advances in air conditioner technology, many modern air conditioners have a longer lifespan than their older counterparts. A well-maintained older system can have a lifespan of 10-15 years, while a newer model can last from 15 to 20 years. 

However, even with a longer lifespan, a newer air conditioning system can have lower running costs due to greater energy efficiency. Newer systems may also require less maintenance, as they can be less prone to breakdowns and have parts that are more readily available compared to older models.  

Maintenance and Cleaning

Regular professional maintenance and cleaning can help keep the running costs of your reverse cycle air conditioner low. Neglecting maintenance and cleaning can cause your air conditioner to be less effective and make it work harder to keep your home climate-controlled. It can also cause your air conditioner to break down and require repairs more often.

Scale and Design of Your Home

Heating and cooling larger homes will, in turn, require a more extensive setup and also lead to increased running costs, compared with a smaller home or apartment. 

Your home’s design can also impact both the initial cost of installation and running costs. Different home materials may require more complicated installation procedures, resulting in a higher cost. 

Additionally, a home constructed with less insulation and single-glazed windows will incur higher air conditioner running costs than a home that is fully insulated with double-glazed windows. This is because home insulation and double-glazing can significantly improve heating and cooling retention in your home, so your air conditioner won’t have to work as hard to keep the climate how you like it. 

Additional AC Features

While a reverse cycle air conditioner’s primary function is to heat and cool your home, it can come with a number of features that impact its running costs. 

  • Dehumidifier: If your air conditioner is equipped with a dehumidifier, it will reduce the amount of moisture in the air. This can be useful on days when the weather feels heavy or muggy in summer, as well as prevent mould growth in the home. 
  • Humidifier: A humidifier function in your air conditioner will add moisture to their air in your room. Adding moisture can be helpful on hot and dry days, as well as prevent dry mouth and eyes when heating your home.
  • Air purifier: Some reverse cycle air conditioners feature an air purifier. These can filter out dust, bacteria and other pollutants.
  • Smart features: Depending on the model, your air conditioner may have smart automations such as wifi controls, eco mode and sleep mode. Some models even come equipped with motion sensors, which can adjust the heating and cooling in a room based on where a person is situated. 

Local Climate

Your local climate has a direct impact on your air conditioner’s usage, and in turn, your running costs. If your local climate experiences extreme heat or cold, you are more likely to use your air conditioner more frequently and at a higher level, leading to higher power consumption and bills.

Split System vs Ducted Reverse Cycle Air Conditioning Costs

Split system and ducted reverse cycle air conditioners may perform similar climate control actions, but are designed to do so in distinct manners. Each system has different advantages, disadvantages and use cases, aligning themselves more with specific house designs, occupant needs and climate function. As a result, the costs can vary between the two setups. 

 

What is a Reverse Cycle Split System Air Conditioner?

A reverse cycle split system air conditioner can both heat and cool the air within a room or space in your home. However, when structured as a split system, the outdoor unit (which expels heat from your home and draws in cool air) is connected to multiple indoor units.

This design allows split systems to provide climate control for individual rooms without the need to install multiple outdoor units. For homes with multiple occupants with varying climate needs, this can be a beneficial choice.

Advantages

  • Precise climate control: A split system air conditioner allows you to control heating or cooling in a space with precision. Multi-split system setups can also allow for greater control within individual rooms and areas of your home than ducted setups
  • Lower installation and running costs: Split system reverse cycle air conditioners tend to have both lower installation and running costs than ducted systems
  • Easier maintenance: Split systems are less complex and take up less space than ducted systems, making maintenance easier in the long run

Disadvantages

  • Limited coverage: A split system air conditioner setup can be less effective for larger rooms/homes than a ducted system, as air is required to travel further to heat or cool a space
  • Aesthetics: The indoor and outdoor units may clash with a home’s design, and offer a less pleasing aesthetic than a ducted system. 
  • Noise: Split system air conditioners tend to be noisier than ducted air conditioners, which can be problematic for light sleepers and those with sensory issues. 

Case study: Split System Reverse Cycle Air Conditioning

Carlos lives in a two-bedroom apartment in Sydney. While his apartment is on the smaller side, the living area can be particularly vulnerable to Sydney’s hot summers and cool winters. Since he spends a lot of time there, this can make the apartment uncomfortable. 

For Carlos, a reverse cycle split system air conditioner is probably the best option for heating and cooling his apartment. The smaller space means the air con won’t have to work as hard to keep him comfortable, making it more cost-effective for Carlso than a reverse-cycle ducted air conditioner. 

What is a Reverse Cycle Ducted Air Conditioning System?

A reverse cycle ducted air conditioner is a centralised air conditioning system which uses a series of air ducts to heat and cool a space. Ducted systems can be used to climate control an entire house. 

Advantages

  • Great for large homes: A ducted air conditioning system can be fitted throughout your entire home, ensuring climate control throughout your house
  • Discrete aesthetic: Reverse-cycle ducted air conditioning systems are fitted into the ceiling and floors of your home. Only the vents will be visible, and these can be customised to complement your home’s decor. 
  • Quiet operation: Ducted systems are quieter than split systems during operation, making them less intrusive to your daily life

Disadvantages

  • Higher installation and running costs: A reverse cycle ducted air conditioning system will have higher installation and running costs than a reverse-cycle split system air conditioner. This is due to the more complex installation, especially over larger areas. 
  • Less precise temperature control: A ducted air conditioning system may not have the precise room temperature control that split systems offer. While some ducted systems offer zoned control, this is not a universal feature. 
  • Maintenance needs: Reverse cycle ducted air conditioning systems involve more complex setups than split systems, making maintenance and repairs more complicated than a split system setup.

Case study: Ducted Reverse Cycle Air Conditioning

Bob and Cheryl are a retired couple who have just bought a four-bedroom home. They have a large living area, and their bedrooms are quite large. Bob and Cheryl frequently have guests over in summer and winter, and tend to use each room of the house frequently.
