Understanding the Energy Star Rating when buying an air conditioner

By December 21, 2020Air Conditioning

Everyone has seen the energy star ratings stuck on the front of appliances, but not everyone knows exactly what they mean. You may shrug these off as being overly technical – but the system is actually quite easy to understand. Let’s take a look!

Why Are The Stars There and Where Did They Come From?

The energy star rating system is a joint government and industry initiative that was established to help consumers make more informed decisions about how energy efficient the products they were buying are. By increasing awareness and transparency about energy consumption, the program also succeeded in increasing demand for more efficient products, thus driving the quality and environmental sustainability of the technology.

The system was introduced in the late 1980s, first in New South Wales and Victoria. It wasn’t until 1992, however, that it became compulsory for products sold all around the country. This was when it became regulated by the Australian government.

Is the Energy Star Rating System the Same For All Appliances?

You will have seen the energy rating sticker on everything from fridges to dishwashers to air conditioners. But are they all the same? The answer is no. Why? The most simple explanation is that every appliance uses energy differently – a 4-star AC unit will not consume the same amount of energy as a 4-star TV.

What Does The Energy Star Rating On An Air Conditioner Mean?

You may have noticed that the rating system on air conditioning systems are a little harder to read because they have two stickers – one for heating and one for cooling (if the unit is a cooling only device, and then it will only have a blue sticker).

As you may have guessed, the more stars, the more energy-efficient the unit is. The maximum possible rating for each side is 10 stars. If the product is rated above 6 stars for heating or cooling, it will show a ‘super efficiency rating’, which goes up to 4 stars (6 + 4 = 10).

However, there is more to it than this. Not all air conditioners are the same: some are larger than others and require more power. So how do you compare the star rating relative to other units? You look at the numbers below each rating system.

These are the capacity output and power input readings – basically how much heating and cooling the unit can produce and how much power it needs to run respectively. When comparing a star rating, you’ll want to be comparing systems that have similar capacity output and power input readings.

So How Do You Choose The Right System?

This may all seem a little confusing, especially when you throw money into the mix. Obviously, you will want to choose the most energy-efficient system possible, but this will also mean spending more money. So how do you choose the right system?

It’s important to remember that units with lower ratings aren’t poor quality units. For a product to be rated at all, it needs to pass rigorous efficiency tests, so the base rating of 1 star is actually quite efficient. It only gets better from there. So it’s really up to you!
