WHAT YOU SHOULD KNOW ABOUT AC UNIT ENERGY RATINGS?

Though the idea of Energy Rating Labels is pretty old, the Australian government recently took it to the next level by introducing a new format for energy efficiency labels. These are based on 3 climate zones in Australia, which makes sense since climatic conditions play a huge role in energy efficiency levels of appliances.

If the same AC unit is expected to work as efficiently in Perth or Albany as compared to Brisbane or Sydney, it wouldn't be fair, would it? 


If you’ve been looking for a new AC unit, you may have spotted the new labels on some AC units but most of them still display the old one. Either way, it’s important for every Australian to know about AC unit Energy Ratings to get the best results and savings from their unit. If you need some advice on the latest energy efficient AC models in the market, you could consult professionals that conduct air conditioner installation Melbourne or in your city. 


Energy efficiency levels are important to know due to a few reasons:

  1. How much your AC is costing you to run

  2. If it's time for repairs or replacement

  3. How much environmental damage is your AC consumption causing


The answers to the first two will give you an accurate answer to the third. 

Star Ratings

AC units are given star ratings based on their features, technology and brand. 1 star is the worst while 6 stars used to be the best at one point. Today, you will find ACs with 8 or 10 stars even.   


The basic idea is - the more stars there are, the higher the efficiency of the model. 

Energy Efficiency Ratio

If you’ve ever heard or read about EER, that stands for energy efficient ratio, especially with relation to air conditioners. EER is calculated by dividing AC unit capacity with the power being used by the unit to operate.  


If you wish to know how well your AC unit is doing and if it's living up to its rating, here’s another formula. Find its energy consumption or rating (not star) number and divide it by 4. The answer is equal to how much it costs to run per year. 


New energy efficiency labels and zones

The three zones in Australia are simply categorized as hot, average and cold.


It goes without saying that any AC unit in the hot zone would have a harder time than in the cold. 


All residential split ACs and window ACs will be required to carry the new labels. Manufacturers of large ducted air conditioners may display their energy efficiency rating via the new label, but it's not mandatory. 


Daikin, LG and Panasonic are the leading energy efficiency AC models currently. If you need guidance on which model, size and type of AC to purchase, get in touch with an air conditioner installation Brisbane, air conditioner installation Sydney or air conditioner installation Perth to help you make an energy efficient decision. Similarly, if your current unit is giving you sleepless nights, thanks to high bills or insufficient cooling, get the experts to look at it. An AC unit that needs cleaning or repair will consume more electricity than needed.

  A decision you have to make every year when the outside temperature rises is -What temperature should I set my air conditioner?  According to the Department of Energy, 78° Fahrenheit is the sweet spot for air conditioners in Australia.

It is never one solid digit that works everywhere for every ac unit.  Knowing what setting works for you will take some fiddling and experimenting. You also need to prioritise whether you want to focus only on energy consumption or want a balance between a comfortable temp and the bills.
