Air Conditioner

How do you set the right temperature on air conditioner?


Aussie summer is in full swing and you may be wondering how to stay cool. One thing many of our clients ask us is how they can set the right temperature on their air conditioner unit. Often, you may find that your space is either too warm or too cold.

I believe that air conditioning is an art. When done right, it makes life so much easier. If you don’t know how to set the right temperature though, you’re not going to enjoy your environment.

If this is something you’ve struggled with, my post may help you find your (temperature) sweet spot. I will also help you figure out how to improve your energy efficiency while staying comfortable.

If you find that your air conditioner system is not helping you stay cool no matter what you try, I’ll also dive into why this may be the case. In these instances, the best solution may be regular air conditioning maintenance.

What is the “right” temperature?

Based on your preferences, your ideal temperature may not be the same at home or your workplace. Here, your set temperature is the highest temperature setting at which you still feel comfortable. 

For most people, this is around 24℃. If you prefer a higher temperature, your consumption will be more efficient. Every temperature increase saves around 10% on your energy use.

How does my air conditioner unit maintain the set temperature?

Your set temperature represents your unit’s cut-off point. Basically, whether you have a system set at 24℃ or lower, the air coming off your coil will be the same.

What’s different is that a lower temperature will require your system to work harder to keep you cool. It will need to push more air to maintain this temperature, resulting in greater energy consumption.

A higher temperature means that your air conditioner system won’t have to work so hard.

What do I need to do?

Maintaining the perfect set temperature now comes down to temperature difference. The difference in correctly-sized systems should be between 10℃-12℃.

If your ideal temperature is 24℃, for instance, your fan coil will need to cool down to 14℃. Here, your air conditioner unit will circulate room-temperature-air using the fan coil until it reaches this temperature.

For a better idea of what I’m talking about, take a look at the image below.

Is your air conditioner unit not cooling your space properly?

Sometimes, it may seem that you can’t find the perfect set temperature.

Whatever you do, your space just doesn’t feel cool enough. Unfortunately, it could mean that there are issues with your condenser coil and fan coil.

I’ve seen that this is usually the case when routine maintenance has not been undertaken. Beyond just inefficient energy consumption, it can pose other problems.

A blocked condenser coil can, for instance, push warm liquid into the indoor fan coil. It will then cycle back to the suction line, requiring it to be cooled. It can also affect your outdoor compressor. An overheated suction line can cause your compressor to burn out.

Coil blockage can also lead to dirty filtration and disrupt airflow distribution, both of which can cause condensation to build up. Ultimately, it will destroy your compressor and burn your unit’s motor.

This means more money spent and a space that doesn’t cool no matter how low you turn your air conditioning.


Commit to regular maintenance to enjoy the perfect temperature

Your air conditioner needs to help you live your best life. If you don’t understand how to figure out the perfect set temperature or if your unit has not been serviced, this is much more difficult.

Maintaining your air conditioner and figuring out the right temperature for your space can also keep your costs lower in the long run. It’s good for you, your wallet, and the environment—a win-win-win.

At Alliance Climate Control, our team of trained technicians offer a specialised maintenance programme for every system. We help you make sure your air conditioner is helping you enjoy a cool space without costing too much.
