Find out moreThe cheapest air conditioning refers to systems with the lowest operational costs over time, considering energy consumption and maintenance requirements. Efficient air conditioning systems provide optimal cooling or heating while consuming minimal energy. In air conditioning, efficiency is measured by how effectively the system converts electrical energy into cooling or heating power, often expressed as the Energy Efficiency Ratio (EER) or Coefficient of Performance (COP).
Australia's most cost-effective and efficient air conditioning systems are typically split system reverse cycle air conditioners with high energy star ratings. Due to their energy-efficient operation, these systems offer affordable purchase prices and low running costs. Conversely, central ducted systems are generally the most expensive to run, particularly in larger homes, due to their higher energy consumption and the need to cool or heat larger spaces.
The main factors influencing the electricity consumption of air conditioning systems include the unit's size and efficiency rating, the area being cooled or heated, insulation quality, outdoor temperature, and usage patterns.
An air conditioning system is a mechanical device designed to control the enclosed space's temperature, humidity, and air quality. Its primary purpose is to create a comfortable indoor environment by removing heat and moisture from the air. Air conditioning systems work on the principle of vapour compression, where a refrigerant circulates through the system, absorbing heat from indoor air and releasing it outside. There are various air conditioning systems, including split systems, ducted systems, window units, and portable air conditioners, each suited to different needs and spaces.
The main types of air conditioning systems include:
The cost differences are primarily due to variations in energy efficiency, installation complexity, and the area they can effectively cool or heat.
The cheapest air conditioning systems are typically window units and portable air conditioners. These systems are less expensive due to their simpler design and easier installation process. However, it's important to note that the cheapest purchasing systems are often not the most cost-effective. Cheaper units generally have lower energy efficiency ratings, which can lead to higher electricity bills over time.
Some of Australia's more affordable air conditioning brands include Kelvinator, Midea, and TCL. These brands offer budget-friendly options without compromising too much on quality. While they may not have all the advanced features of premium brands, they provide reliable cooling solutions for many households. It's important to note that even within these brands, a range of models can have varying efficiency ratings and features.
Efficient air conditioning systems provide the desired cooling or heating effect while consuming minimal energy. The most efficient systems typically have high Seasonal Energy Efficiency Ratio (SEER) ratings and employ inverter technology.
According to a 2020 study by Energy Rating Australia, reverse cycle split system air conditioners with seven or more stars can use up to 70% less energy than a 2-star model of the same capacity. For example, a 7-star 2.5kW split system air conditioner can use as little as 270 kWh per year, compared to over 900 kWh for a 2-star model of the same size.
Energy efficiency in air conditioning systems refers to the cooling or heating output ratio to the energy input. Features that contribute to energy efficiency include:
The cost of running an air conditioner in Australia varies significantly depending on the type of system, its size, efficiency rating, usage patterns, and local electricity rates. According to a 2021 study by Canstar Blue, the average cost to run a medium-sized (5kW) split system air conditioner in Australia is approximately $0.25 to $0.35 per hour.
This can translate to annual costs for residential units ranging from $200 for efficient systems used moderately to over $1,000 for less efficient systems used frequently. Commercial units, typically more extensive and used more intensively, can cost significantly more to run.
These figures are based on average electricity rates and usage patterns across Australia. Actual costs may vary depending on specific circumstances and location.
The cost of running an air conditioner in Melbourne varies seasonally due to the city's variable climate. During summer, a typical 5kW split system air conditioner might cost around $0.30 to $0.40 per hour, based on average usage patterns and a power consumption 1.5kW/h.
Electricity rates in Melbourne average around $0.20 to $0.30 per kWh, which significantly influences the final cost. During peak summer months, a household might spend $2 to $3 daily on air conditioning, assuming 6-8 hours of use. However, actual costs can vary widely based on individual usage patterns and the specific efficiency of the unit.
The running cost for a split air conditioning system in Australia typically ranges from $0.20 to $0.50 per hour, depending on capacity, SEER rating, usage patterns, electricity rates, and maintenance.
A split air conditioning system comprises indoor and outdoor compressor units connected by refrigerant lines. These systems are generally more efficient than window or portable units, especially when equipped with inverter technology.
Ducted air conditioning systems in Australia typically cost between $1 to $3 per hour, making them one of the more expensive options. This higher cost is due to their larger capacity and the need to cool or heat multiple rooms or an entire house.
Ducted systems distribute conditioned air through a network of ducts to various rooms in a building. While they offer whole-home comfort, their running costs can be significantly higher than other air conditioning systems.
Portable air conditioners in Australia typically cost between $0.40 to $0.70 per hour to run, making them one of the more expensive options in terms of operating costs relative to their cooling capacity.
Portable air conditioners are self-contained units that can be moved from room to room. While they have lower upfront costs, their energy efficiency is generally lower than split or ducted systems, resulting in higher running costs for the amount of cooling provided.
Australia's most expensive air conditioning systems are typically large ducted systems, especially those with lower energy efficiency ratings. These air conditioner systems can cost upwards of $3 per hour to operate during peak times. The high running cost is due to their large capacity, the energy required to distribute air throughout a house, and the tendency to cool or heat unoccupied spaces.
Factors influencing air conditioning running costs include:
Consider upfront and long-term costs to choose the most energy-efficient air conditioning system. Look for systems with high energy star ratings and lower running costs. Consider the space size to be cooled and choose an appropriately sized unit. Split systems often offer a good balance of purchase price and running costs for single rooms or open-plan areas.
