Before purchasing a new air conditioning system, it’s important to consider not only the upfront price, but also the potential ongoing expenses of using a particular system. Understanding costs and how they can be influenced by available features, installation, operation, maintenance, and your local climate can help you select the right system for your home.

The popularity of reverse cycle air conditioners in Australia in recent years hasn’t been driven solely by their efficiency, but also by their affordability. This guide will take you through the potential costs of this system and the factors that can influence them. Overall, we’ll help you make an informed choice when purchasing your reverse cycle air conditioner.

How Does a Reverse Cycle Air Conditioner Work?

A reverse cycle air conditioner is a type of air conditioning system that can both heat and cool a space within your home. It is available as both multi-split and single-unit systems to suit different home layouts and room requirements.

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

Costs Involved with Reverse Cycle Air Conditioners

Like any other type of air conditioner, a reverse cycle air conditioner involves expenses beyond the initial cost of purchasing the unit. Understanding these potential expenses can help you plan your budget and choose the most economical system for your home.

When you’re considering purchasing a reverse cycle air conditioner, you should take these key factors into account:

•       Running expenses
•       Installation process
•       Maintenance requirements
•       The expense of repairing or replacing an existing air conditioner,
•       How your local climate may influence your air conditioner usage

Running Costs

The operating costs of a reverse cycle air conditioner depend on several different factors, all of which should be evaluated before making your purchase.

• The specific type of reverse cycle air conditioner you have: Ducted, split system and multi-split system air conditioners can all operate as reverse cycle air conditioners. Since they function differently and are designed for different applications, their running costs will vary.
• The size of the space being heated/cooled: Smaller rooms and spaces generally need less heating and cooling than larger areas, which can affect your electricity bills. The size of the area being heated or cooled can also influence which reverse cycle air conditioner is most suitable for you. Generally, split system air conditioners are effective for precisely heating and cooling a specific room or area, while ducted air conditioners provide coverage throughout the entire home.
• Energy efficiency: Australian air conditioners use a star rating system to indicate efficiency. An air conditioning system with a higher energy efficiency rating will generally use less electricity than one with a lower rating, affecting overall running costs.
• Heating vs cooling usage: Generally speaking, operating the cooling function of your reverse cycle air conditioner can cost more per hour than using the heating function.

Installation

Similar to running costs, the cost of installing a reverse cycle air conditioner depends on the particular air conditioning system you purchase. However, installation expenses can also be affected by the preparation required for your home and the features included with the system.

• Reverse cycle ducted air conditioners will generally be more expensive to install than split system or multi-split system air conditioners. This is because ducted installation requires substantial modifications to your home and its structure, particularly when installing ductwork across several rooms
  
  
• Reverse cycle split system air conditioners are generally less expensive to install than ducted or multi-split systems, as they require only one indoor unit and one outdoor unit to be installed.
• Reverse cycle multi-split system air conditioners cost more to install than a single split-system air conditioner, but they provide greater coverage throughout a home. Multi-split systems can also provide significant installation savings compared with ducted systems. However, the final installation cost can vary depending on how many indoor units you choose to install in your home.

Maintenance

Regardless of the particular reverse cycle air conditioning system installed in your home, it’s essential to stay on top of its maintenance. This helps ensure your system continues operating efficiently while also extending its lifespan and reducing the likelihood of unexpected repair expenses in the future.

Upgrading Outdated Air Conditioning Systems

The cost of replacing your existing air conditioning system can vary significantly, depending on your home’s current air conditioning setup and your preferred upgrade options. Although there may be a considerable upfront expense, replacing an older air conditioner can be a cost-effective choice because of technological advancements and improved efficiency in newer models.

If you’re considering replacing your old air conditioner, you may be able to benefit from government rebates available in your state and reduce your expenses. AML Air Conditioning & Electrical may also have rebates and promotions available to help you save money.

Local Climate

Your local climate will influence how you use your reverse cycle air conditioner and, consequently, affect your running costs. You will generally spend less on heating or cooling your home with air conditioning if you live in an area with a mild climate compared with living somewhere that experiences extreme heat and/or cold.

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

Installing a reverse cycle air conditioner can be a worthwhile addition for maintaining comfortable indoor temperatures. Regardless of the air conditioner type, several factors can influence the overall running costs of your system over time.

Lifespan

Thanks to continued advancements in air conditioner technology, many modern systems can have a longer lifespan than their older counterparts. A properly maintained older system may last around 10-15 years, while a newer model can typically operate for 15 to 20 years.

However, despite their longer lifespan, newer air conditioning systems can offer lower running costs because of improved energy efficiency. Modern systems may also need less maintenance, as they can be less susceptible to breakdowns and have replacement parts that are more readily available than those for older models.

Maintenance and Cleaning

Regular professional servicing and cleaning can help keep the running costs of your reverse cycle air conditioner lower. Failing to maintain and clean your system can reduce its effectiveness and force it to work harder to maintain comfortable temperatures throughout your home. It can also increase the chance of breakdowns and more frequent repair requirements.

Scale and Design of Your Home

Heating and cooling a larger home will generally require a more extensive system and can result in higher running costs compared with a smaller home or apartment.

Your home’s design can also influence both the upfront installation price and ongoing operating expenses. Certain building materials and layouts may require more complex installation work, which can increase the overall cost.

Additionally, a home with limited insulation and single-glazed windows will generally have higher air conditioning running costs than a property with effective insulation and double-glazed windows. This is because insulation and double glazing can significantly improve heat retention and cooling performance, meaning your air conditioner may not need to work as hard to maintain your preferred indoor temperature.

Additional AC Features

While the main purpose of a reverse cycle air conditioner is to heat and cool your home, many systems include additional features that can influence their running costs.

• Dehumidifier: If your air conditioner includes a dehumidifier, it can reduce moisture levels in the air. This can be helpful during heavy or humid summer weather, while also helping reduce conditions that encourage mould growth inside the home.
• Humidifier: A humidifier function in your air conditioner adds moisture to the air within your room. This can be useful during hot and dry conditions and may help reduce dry mouths and eyes when heating your home.
•  Air purifier: Some reverse cycle air conditioners include an air purification function. These systems can help filter dust, bacteria and other airborne pollutants.
•  Smart features: Depending on the model, your air conditioner may offer smart functions such as Wi-Fi controls, eco mode and sleep mode. Some systems may also include motion sensors that can adjust heating and cooling based on where people are located within a room.

Local Climate

Your local climate directly affects how often your air conditioner operates and, consequently, your running expenses. If your area experiences extreme temperatures, you may need to use your air conditioner more frequently and at higher settings, resulting in greater electricity consumption and higher energy bills.

Split System vs Ducted Reverse Cycle Air Conditioning Prices

Split systems and ducted reverse cycle air conditioners can provide similar heating and cooling functions, but they are designed to deliver climate control in different ways. Each system has distinct advantages, disadvantages and applications, making them more suitable for particular home layouts, occupant requirements and climate conditions. As a result, the costs associated with each system can vary depending on the setup.

What is a Reverse Cycle Split System Air Conditioner?

A reverse cycle split system air conditioner can heat as well as cool the air inside a room or area of your home. However, when designed as a split system, the outdoor unit (which removes heat from your home and brings in cool air) is connected to several indoor units.

This configuration allows split systems to provide climate control for separate rooms without requiring several outdoor units. For homes with multiple occupants who have different temperature preferences, this can be a practical option.

Advantages

• Precise climate control: A split system air conditioner gives you accurate control over heating or cooling within a space. Multi-split system configurations can also provide more control across individual rooms and areas of your home than ducted systems.
• Lower installation and running costs: Split system reverse cycle air conditioners generally have lower installation and operating costs compared with ducted systems.
• Easier maintenance: Split systems are simpler and occupy less space than ducted systems, which can make maintenance easier over time.

Disadvantages

• Limited coverage: A split system air conditioner can be less suitable for larger rooms/homes than a ducted system, as air needs to travel farther to heat or cool an area.
• Aesthetics: The indoor and outdoor units may conflict with your home’s design, providing a less attractive appearance than a ducted system.
•  Noise: Split system air conditioners are generally louder than ducted air conditioners, which can be troublesome for light sleepers and people with sensory sensitivities.

Case study: Split System Reverse Cycle Air Conditioning

Carlos lives in a two-bedroom apartment in Sydney. Although his apartment is relatively small, the living area can be particularly affected by Sydney’s hot summers and cool winters. Since he spends considerable time there, this can make the apartment uncomfortable.

For Carlos, a reverse cycle split system air conditioner would likely be a suitable option for heating and cooling his apartment. The smaller space means the air conditioner will not need to work as hard to maintain his comfort, making it more economical for Carlos than a reverse-cycle ducted air conditioner.

How Does a Reverse Cycle Ducted Air Conditioning System Work?

A reverse cycle ducted air conditioner is a centralised air conditioning system that uses a network of air ducts to heat and cool an area. Ducted systems can provide climate control throughout an entire house.

Advantages

• Great for large homes: A ducted air conditioning system can be installed throughout your entire home, providing climate control across your house
• Discrete aesthetic: Reverse-cycle ducted air conditioning systems are installed within the ceilings and floors of your home. Only the vents remain visible, and these can be customised to match your home’s decor.
•  Quiet operation: Ducted systems operate more quietly than split systems, making them less disruptive to your everyday life

Disadvantages

• Higher installation and running costs: A reverse cycle ducted air conditioning system generally has higher installation and operating costs than a reverse-cycle split system air conditioner. This is because installation is more complex, particularly across larger areas.
• Less precise temperature control: A ducted air conditioning system may not provide the same precise room temperature control as split systems. Although some ducted systems include zoned control, this feature is not available on every system.
• Maintenance needs: Reverse cycle ducted air conditioning systems have more complex configurations than split systems, which can make maintenance and repairs more complicated than with a split system setup.
