Energy Efficiency Ratings


Energy and efficiency ratings are important for consumers of air conditioners in Australia. Consumers view Energy Star ratings as pivotal pieces of information in providing a comparative evaluation of energy efficiency.

The information has to do with the amount of energy that an air conditioning appliance consumes in a year. This information is on the basis of an appliance’s normal use at home.

Consumers rely on this information to know the products to buy and the ones to avoid. The Australian government plays a huge role in ensuring that standards of energy efficiency in air conditioning units are put in place.


Australian law stipulates the standard that air conditioning units must reach for approval to be in the market. The air conditioning units approved by the Australian government to be sold and provided to consumers have the Energy Star label. The air conditioners with the most efficient energy consumption ratings have the TESAW award. The TESAW award is sponsored by the government and it is presented annually.


The efficiency of air conditioning depends on various important factors. The elements include: maintenance, age, system type, and internal components. In order to measure the efficiency of air conditioning units, the following measurements are used: Energy Efficiency Ratio and Coefficient of Performance.

The Energy Efficiency Ratio has to do with the measurement of an appliance’s cooling performance. Normally, it is measured in kilowatts. Cooling capacity refers to the amount of heat that a room emits. On the other hand, heating capacity refers to the amount of heat added.

The Coefficient of Performance refers to the energy efficiency of a unit when releasing energy in a room. Normally, the heat from an air conditioning unit has a higher amount of efficiency compared to other methods of heat emission.


Air conditioners have to show the Zoned Energy Rating Label. This is a vital factor that manufacturers and suppliers have to put into consideration when importing and supplying air conditioners. Essentially, the Zoned Energy Rating Label is an efficiency rating for 3 climate zones in Australia and New Zealand. The importance of this rating information is that it allows consumers to learn more about the products they are buying. With this information, they are able to choose a product that has a high level of performance and that which saves energy. Typically, air conditioning units that consume high amounts of energy are disadvantageous for consumers because they are costly in the long run. Whenever consumers go to the market to shop for air conditioners, there are specific elements they are looking for. If they find them in a brand, they consider it and buy from them.


It is without a doubt that most homes in Australia have air conditioning units. For those who don’t have, they would definitely want to have one. Since Australia is a hot weather climate, the need for air conditioning is massive in most Australian homes. It is a part of their lives. They have to find a way of cooling their homes. As heavy consumer of air conditioners, Australians have a better understanding of the brands that offer the best air conditioning units. They rate air conditioners based on their distinct features and quality of functionality.

Based on the above-mentioned basis for rating, the brand that most Australians prefer in regards to air conditioning is Mitsubishi Heavy Industries. The brand has a five-star rating for offering the best overall satisfaction level compared to other brands like Kelvinator and Panasonic. As the brand rated highly in most categories, most Australians prefer it for their air conditioning needs. Of course, this is a challenge to other brands manufacturing air conditioners. They have to meet the needs and preferences of consumers for them to increase their ratings.

Indeed, the demand for air conditioners cannot be underestimated in hot climatic regions. That is why standards of energy efficiency are imperative. Saving energy and consideration of high quality performance are paramount. Consumers want to use products that will not only meet their needs but also be safe to use. For this reason, the government has to come in and provide the necessary standards and regulations for maintaining energy efficiency.
