When buying air conditioners and other home appliances, one of the key things that experts advise on is checking energy efficiency. That is because of numerous benefits that come with investing in energy-efficient air con. But what is energy-efficiency in an air conditioner? Unfortunately, most buyers do not understand what it is and why it is important. This energy-efficient air conditioner guide goes into details to elaborate on what energy-efficiency is.

We have also listed the type of energy-efficient air cons in the market as well as the pros and cons of investing in this type of air con installation.

Types Of Energy-Efficient Air Cons

The term energy efficiency is widely used by most of the air conditioner manufacturers. In fact, most of them are using these labels to advertise their products. So what does it mean? Energy efficiency simply means that the machine is using less energy and still provide better output than the traditional models.

Energy efficiency in machines is achieved by doing more with less. You can either have the same out as the alternative machine but use just a fraction of the energy that could have been used by the tradition model. To achieve high energy efficiency, manufacturers are using cutting edge technologies that reduce air cons’ energy consumption by a significant amount.

As you have seen with most brands, the energy efficiency of an air conditioner is rated by energy stars. The number of stars (star rating) on the label shows how energy efficient the machine is. Most of the air cons are rated between 1 to 6 stars. So a machine with 6 stars is highly rated and offers incredibly high energy efficiency. However, there are addition 4 stars for extra-efficient air conditioners. There are some super energy efficient air cons that can hit a 10-star rating. But that does not mean 1-start rated air con is bad.

Types Of Energy-Efficient Air Cons

There are two main types of air conditioners- evaporative and refrigerate. The latter excels in high humidity environment such as tropical climate while the former excels in cooling dry air. So to reduce energy consumption, you need to consider the kind of environment that you live in. You can select the right air con that suits your needs. If you are in a region where high humidity is experienced year-round, get a refrigerate type and vice versa. That’s how you save in energy bills.

There is a number of energy efficient air con that you pick from in Australia. These are machines that have been improved using cutting edge technology. Here are some of the best types of energy-efficient air cons you can get in Australia:

  1. Split-system air con- they are very common in Australia due to their flexibility and high performance. They have to units- indoor unit (evaporator) and the outdoor unit (compressor and condenser).
  2. Duct air conditioners- if you have a large home, there ate energy efficient ducted air cons to select from.
  3. Window air cons- if you are cooling single rooms, you have plenty of high energy-efficient window air cons to pick from.

4 Energy-Efficient Air Con Initiatives

One of the shocking findings is that more than 40 per cent of the Australian household energy consumption is from HVAC appliances. That is according to the 2011 Federal government report. Therefore, choosing energy efficient air conditioner is crucial in for the Australians. There are a number of energy-efficient AC initiatives that are helping buyers select the best air cons in the market. Here are just a few of them:

The E3 Program

The Australian government and New Zealand government are collaborating in running the Equipment Energy Efficiency (E3) program. The program undertakes a number of activities including education, training, energy rating labelling and setting minimum energy performance (MEPS). The aim is to help buyers get appliances with good energy efficiency.

Right Size AC

No matter the measures you have taken to get a highly efficient machine, size is a critical factor to consider. If the air con unit is too large, there is wastage. If it is too small, it works hard and thus reducing efficiency. You must get a perfect size for your house to reduce energy wastage.
