So how do we keep our homes cool and our bank accounts happy? That's where the art of balancing comfort and energy costs comes into play.

In this guide, we'll dive into the ins and outs of air conditioning systems, discuss the factors that affect energy costs, and provide you with a treasure trove of tips to optimise aircon usage. We've got you covered, from setting a new air conditioner to the right temperature to leveraging energy-saving features.

 

What are Air Conditioning Systems?

Picture this: It's a scorching summer day, and the heat outside temperature already feels like a relentless wave crashing down on you. Enter air conditioning, your trusty ally against hot, sweaty discomfort. But what exactly is air conditioning?

In a nutshell, air conditioning alters the temperature, humidity, and overall air quality within a space to create a more comfortable environment. It's like having your personal weather control system in your home or office. The magic of air conditioning lies in its ability to remove heat and moisture from the air and indoor humidity and leave you with cool, crisp, and refreshing air to breathe.

 

Types of Air Conditioners Commonly Used in Rental Properties

Regarding air conditioning options commonly used in rental properties, there are several types to choose from. Let's explore some of the most popular ones:

Ducted Air Conditioning

Ducted air conditioning systems are often preferred for larger rental properties or those with multiple rooms. These systems consist of a central unit that cools and distributes the air through a series of ducts, delivering cool air to each room through vents. Ducted air conditioning offers whole-house cooling with the ability to control individual room temperatures.

 

Split System Air Conditioning

Split-system air conditioners are popular for residential and rental properties. They consist of two main components: an indoor unit that blows cool air into the room and expels heat. Split systems are versatile and efficient. They are often installed on walls or mounted on the ceiling.

 

Window/Wall Air Conditioner

Window or wall air conditioners are compact units typically installed in a window or an opening in an external wall. They are a cost-effective option for smaller rental properties or individual rooms. These units cool the air and expel heat through the back or sides. They offer easy installation and can be a convenient solution for localised cooling.

 

Portable Air Conditioner

Portable air conditioners are versatile units that can be moved around and placed in different rooms. They typically have a ceiling fan and a vent that exhausts hot air from a window or through a wall. Portable air conditioners offer flexibility and suit tenants who cannot permanently modify the property.

Each type of air conditioner has advantages and considerations depending on the property size, layout, and individual preferences.

 

Factors Affecting Energy Costs

Now that we've acquainted ourselves with the different air conditioning systems, it's essential to understand the factors influencing energy costs. By being aware of these variables, we can make informed decisions to optimise our aircon usage and keep our energy bill in check.

 

Outdoor and Indoor Temperature

Outside and indoor temperatures significantly impact your air conditioning's energy consumption. On scorching hot days, when the mercury rises, your aircon works harder to cool the air to your desired temperature. The greater the difference between outdoor and indoor temperatures, the more energy your air conditioner will consume.

 

Humidity Levels

Humidity levels can also affect how your air conditioning system operates. High humidity makes the air feel sticky and uncomfortable, prompting your aircon to work harder to remove heat and moisture from the air. This increased workload can lead to higher energy consumption and, subsequently, higher energy bills. Keeping humidity and consistent temperature levels in check can help optimise energy usage.

 

Energy Consumption and Power Bills

Unsurprisingly, the more energy your air conditioning unit consumes, the higher your power bills will be. Energy consumption depends on factors such as your unit's cooling capacity, the system's efficiency, and how long and frequently it is used. Being mindful of energy consumption and finding ways to reduce it can lead to significant savings on electricity bills.

 

Impact of Heating and Cooling on Energy Bills

While air conditioning provides cool relief during hot days, heating your rental property during colder months can also affect energy costs. Heating systems, including reverse cycle air conditioners, consume energy to move warm air into your space. Balancing the usage of heating and cooling throughout the year and optimising temperature settings can help manage energy bills.

 

Energy Efficiency of Air Conditioning Units

Your air conditioning unit's energy efficiency is critical in determining how much energy it costs. High-efficiency units are designed to deliver optimal cooling while minimising energy consumption. Look for units with a high Energy Efficiency Ratio (EER) or a good star rating to ensure you get the most out of your aircon without draining your wallet.

 

Optimising Aircon Usage for Energy Savings

Now that we understand the factors that affect energy costs, it's time to explore practical tips and strategies to optimise our aircon usage. By implementing these techniques, we can strike the perfect balance between staying comfortable and saving energy. Let's dive right in!

 

Setting the desired temperature:

• Balancing comfort and energy costs: Finding the sweet spot between comfort and energy efficiency is crucial. Avoid setting your air conditioner to extremely low temperatures, as it significantly increases energy consumption. Instead, opt for a temperature that keeps you comfortable without overworking the aircon.
• Recommended temperature ranges for different seasons: During the hot Aussie summer, aim for a temperature range between 23 °C and 26 °C (73 °F and 79 °F) to achieve a cool and comfortable indoor environment. In winter, adjust your reverse cycle air conditioner to a cozy temperature range of 18 °C to 20 °C (64 °F to 68 °F) for heating.

 

Using energy-saving modes and features:

• Energy-saving mode on air conditioning units: Most modern air conditioning units come equipped with an energy-saving mode. Activate this mode to optimise energy usage by adjusting the cooling output and fan speed based on the desired temperature. It helps maintain a comfortable environment while reducing energy consumption.
• Utilising smart thermostats and AC controllers: Upgrade your aircon experience with smart thermostats and AC controllers. These intelligent devices offer features like sleep mode and economy mode, which automatically adjust temperature settings and fan speeds to conserve energy without compromising comfort. Some even utilise human sensors and remote control functionalities to optimise energy usage based on occupancy.

 

Leveraging natural ventilation and other cooling options:

 

Regular maintenance and air filter cleaning:

• Importance of clean air filters for energy efficiency: Regularly clean and maintain your air filters to ensure optimal energy efficiency. Dirty filters restrict airflow, making your aircon work harder to cool the air. Cleaning or replacing filters, as the manufacturer recommends, helps maintain proper airflow, reducing energy consumption.
• How dirty filters can impact energy consumption: A dirty filter can increase energy consumption by up to 15%. It affects the cooling efficiency of your aircon and strains the system, leading to higher energy bills. Make it a habit to clean or replace filters every few months to keep your aircon running smoothly and efficiently.

By implementing these aircon optimisation strategies, you can enjoy a comfortable indoor environment while controlling electricity costs and bills.
