Fan mode for air conditioners: functionality and benefits

How does fan mode work?

When you turn fan mode on, the fan works but the compressor is turned off. This means that the air conditioner neither cools nor warms the air; it simply moves it around within the room. Depending on the model, the fan speed can be set to different levels (low, medium, and high).

Unlike cool mode, which turns the compressor on to lower the temperature, fan mode keeps the air circulating to maintain ventilation without increasing energy consumption. This makes it an efficient alternative when there is no need to cool the air.

There are different types of fans within air-conditioning systems, in accordance with their technology and use:

• Helicoidal or axial fans: these move large bodies of air with low pressure, which is ideal for improving circulation.
• Radial or centrifugal fans: this type of fan moves the air outwards, while its blades can be angled forwards or backwards, depending on the design.

Advantages of fan mode

This mode offers various benefits besides the simple act of ventilation. It is perfect for the moderately warm days in early or late summer because it moves the air around without the need to turn on the cooling system. It is also useful for lowering humidity in closed spaces to make a more comfortable environment.

This function also helps to optimise the performance of the air-conditioning system, reducing unnecessary wear and tear on the compressor for a longer working life.

Main benefits of the fan mode

We can therefore summarise some of the most important advantages as follows:

• Energy saving: it consumes a lot less power because the compressor is not running.
• Better ventilation: it prevents the air from going stale, moving it about evenly.
• Lower humidity: it helps to reduce the feeling of humidity and prevent condensation without lowering the temperature.
• Less noise: it makes less noise than cold or heat modes.
• Longer-lasting equipment: it reduces the wear and tear on the compressor, ensuring that your air conditioner lasts longer.
• Odour removal: it freshens up the air in stuffy rooms.

As we mentioned previously, this mode is particularly useful on warm days when there is no need to cool or heat the air, but only to make it circulate more. It is also an efficient way to lower the cost of your electricity bills.

Alternatives to air conditioning: types of fans

If you want a more economical and portable option, fans are an excellent choice. There are various types with specific features:

Tower fans

These are compact, stylish, and ideal for small spaces. They often include functions such as oscillation and ionising.

Standing fans

With adjustable height and powerful air streams. They are versatile and easy to move between rooms.

Ceiling fans

Fixed and very efficient, they move the air evenly around the whole room.

Desktop fans

Small and portable, they are ideal for desks and small spaces.

Bladeless fans

Modern and safe, they create a constant flow of air without visible blades.

Industrial fans

Bigger and more powerful, they are perfect for larger spaces such as warehouses or factories.

Nebuliser fans

This kind of fan contains a water chamber to create a refreshing cooling sensation.

The choice will depend on your needs and the space you are going to use it in, even if each option has its pros.

Choosing the most efficient option

The choice between your air conditioner’s fan mode and other fans will depend on the type of space and level of comfort you are looking for.

If you want to improve air circulation without changing the temperature and optimise your energy consumption, fan mode is an excellent alternative. It is ideal for rooms with good natural ventilation because it can move the air around without turning the compressor on. It can also help to maintain a cool atmosphere without dryness, which is more comfortable on warm days.

On the other hand, if you want a more portable, flexible, and affordable solution, your most convenient option would probably be a fan. There is a wide range of models available, from standing fans to towers or ceiling fans, to adapt to different spaces and needs. Their low energy consumption makes them an efficient alternative for cooling rooms without spending a lot of money.

The key is to find the perfect balance between comfort, consumption, and sustainability. For example, in cooler areas, fan mode improves air circulation without the need for cooling. In warmer regions though, its use in cooler times of the day—along with nebulising fans—will enhance the refreshing feeling. If you live in an area somewhere between these, the combination of fan mode and fans will guarantee energy efficiency with no loss of comfort.

In short, choosing a solution that minimises energy impact and is more convenient is the first step towards a more efficient and comfortable home.
