What Temperature Should I Set My Air Conditioner in Summer

Asking what temperature to set your Air Conditioner on during summer has become a frequently asked question. Every person getting an air conditioning installation in Melbourne wants to know the perfect temperature their AC unit should be at during the summer.

Ideally, it is recommended to set your air conditioner’s temperature between 23°C to 24°C for maximum comfort levels, and between 25°C to 27°C for maximum energy saving, but that is if you do not consider the weather factor. When you consider the weather conditions of the area you are living in, the ideal temperature defers. Therefore, it is important to take into account the weather conditions before tuning your air conditioner unit to maintain a specific temperature for your home.

If you are feeling confused at this point, worry not, more explanation is on the way. In this post, we’ll be looking into some of the ways in which you can find the perfect temperature for your air conditioner unit to run on. We’ll also discuss a few points of action in case your Air Conditioner is not able to maintain the right temperature.

Things to Consider When Setting The AC Temperature

Often, people step into their homes and immediately set the AC to drop the temperature to their usual 18°C to 21°C. While a lower temperature can make you feel more comfortable, it’s not always the best level to maintain for your Air Conditioner, or for your house. Whenever you are setting the temperature on your Air Conditioner, make sure to consider the following things.


Based on your lifestyle preferences, your ideal temperature may not be the same at your home or at your workplace. In fact, your ideal temperature is the highest temperature that your body still feels comfortable at. For many people, this temperature is around 24°C.

However, not everyone feels the same ambience at the same temperature. The differences could be because of many factors such as the place they are born, their body fat, their usual lifestyle and much more. Therefore, it is important to find out your ideal temperature first, so that you can decide to what level you can make your Air Conditioner work.

Energy Efficiency

Without a doubt, it is important for you to take into account the energy bills your air conditioner is generating while you are deciding the most comfortable temperature your Air Conditioner can work on. If you are blindly lowering the temperature to what makes you feel best, then you must not care about your Air Conditioner’s health and the energy bills you are paying.

But if in case you are worried about your energy bills, then keep in mind that every temperature increase on your Air Conditioner can save 10% on your energy usage. Therefore, to keep your energy bills in control, make sure you know your ideal temperature first, and then set the AC temperature to a level closer to it, so that you can be comfortable as well as save on your energy bills.

Weather Condition

The season you are in and the weather conditions in your area play a vital role when it comes to setting up the temperature on your AC. If it’s too hot in summer, your Air Conditioner can definitely bring down the level of heat in your home providing great comfort. However, you cannot set the same level of temperature during winter, mainly because the weather conditions are already very cool.

Is Your AC Not Cooling Like It Should?

Air Conditioners are without a doubt a vital piece of equipment these days. The heat has increased significantly over the years and without a working air conditioner, surviving this heat is a matter of life and death. This is why people spend a lot of money and time on aircon servicing.

If your air conditioner is not cooling like it should, then its recommended that you get your air conditioner serviced as soon as possible. However, let us look at some of the common reasons why your air conditioner might not be working as efficiently as before.

Clogged Filters

One of the most common reasons behind inefficient air conditioning is clogged filters. Over time with usage, the AC filters accumulate dirt, pet and human hair, pollen, and dust. These particles clog your filters causing your air conditioner to restrict the flow of air. The result is inefficient cooling.

Clogged filters can also lead to interference in the functioning of your AC system’s indoor evaporator coil and outdoor condenser unit. This in turn can damage your AC unit and may lead to increased repair costs than expected.

The Refrigerant Low or Leaking

All Air Conditioner units use a chemical called refrigerant. This chemical is used by the AC unit to transfer heat from indoors to outdoors. There are many types of refrigerant available in the market, and you can pick any that suits your AC unit. But the point is that if the level of this refrigerant is low in your AC system, it may not be effectively cooling the indoors.

There are two main reasons for this to happen. One is that the refrigerant might have been undercharged during the air conditioner installation in Melbourne, and the chemical may have been all used up. However, the second reason is more common and is usually a result of a leak in the system. If the second reason is the cause, then it is recommended that you consult professional air conditioner servicing immediately.

Coils are Frozen or Dirty

As you keep on using your Air Conditioner, the coils within the system stay humid and this can cause mould and mildew to grow on it. This can cause the low efficiency of the system. Another case is that the coils within your AC unit might have been frozen. This mainly happens because of low refrigerant levels in the unit and can also result in inefficient cooling.
