Using a Portable Air Conditioner – What to Keep in Mind? General information

A portable air conditioner is a quick and convenient way to ensure thermal comfort in your home or office. However, to fully utilize its capabilities, it is worth knowing a few basic rules regarding its use. Proper placement and operation of the device can not only improve its effectiveness but also significantly impact energy bills.

Place the air conditioner in the right spot

The location where you set up the mobile air conditioner has a significant impact on its efficiency. It is best to place it near a window, as the exhaust hose should be as short and straight as possible. Make sure there is adequate space around the device – both in front and behind. This way, the air conditioner can freely draw in air and cool it effectively.

Avoid placing the air conditioner in sunny spots – direct sunlight can increase the temperature of the device's casing, reducing its efficiency. It is also advisable to cover windows with blinds or curtains to minimize room heating.

Another important issue is the availability of electrical power – while our devices have long power cords, it is best to find a spot close to an outlet – this way, you will reduce the risk of tripping over the cord or accidentally unplugging it, not to mention the aesthetic aspects or the need to use extension cords.

Seal the exhaust hose outlet properly

The exhaust hose is the component responsible for expelling hot air from the room. To avoid losing cool air and letting hot air in from outside, it is essential to properly seal the window or door through which the hose passes. The best solution is to use special sealing kits – available for both tilt and sliding windows.

By sealing, we increase the efficiency of the air conditioner and limit the amount of outside air that would need to be cooled again.

With our portable air conditioners, you will, of course, receive a complete set of the exhaust hose for expelling hot air outside along with mounting elements and sealing tape.

Set the appropriate temperature

Many users set the air conditioner to the lowest possible temperature, expecting quick cooling of the room. However, this is a mistake – such action increases energy consumption without significantly affecting the cooling time.

It is recommended to set the target temperature at 22–24°C, which is optimal for comfort and savings. It is also important not to cool the room too intensely – the temperature difference between the interior and the environment should not exceed 6–7°C to avoid thermal shock when leaving the room.

Ensure good air circulation

Good air circulation in the room is essential for the effective operation of the air conditioner. Curtains, furniture, or other objects blocking airflow can significantly reduce its effectiveness. Make sure nothing obstructs the air intake grille.

In larger rooms, it is worth considering using models equipped with a powerful fan or even a separate standing fan to help evenly distribute cool air throughout the space.

Close doors and windows

To maintain a low temperature in the room, remember to close doors and windows. Otherwise, the air conditioner will have to work harder to maintain the set parameters – which will result in higher energy consumption and a shorter lifespan for the device.

If you have several rooms in your home, use the room air conditioner in one closed room instead of trying to cool the entire open space – this solution is much more efficient.

Use programming and night mode functions

Many models of portable air conditioners, including those offered by Termofol, have programming functions and ECO or night modes. Utilizing these options allows you to maintain a comfortable temperature without unnecessary energy consumption.

The night mode often reduces noise levels and automatically adjusts the temperature to provide optimal sleeping conditions. The timer allows you to turn on the air conditioner before you return home – without the need for the device to run all day. You can also control the air conditioner using the TERMOFOL SMART app and WiFi. All models in our offer are equipped with a WiFi module, which significantly increases the usability of the devices – you can turn on the device remotely, for example, when leaving work, and enjoy a cooled apartment as soon as you step through the door!

Cleaning the filters of the portable air conditioner

A portable air conditioner, like any other device, requires maintenance. Air filters should be cleaned every few weeks – too much dust can restrict airflow and reduce cooling effectiveness. It is advisable to set a reminder in your calendar so you don’t forget this task.

Regular cleaning not only improves efficiency but also affects the air quality in the room – which is particularly important for allergy sufferers.

Importantly, cleaning the filters in our portable air conditioners is not a complicated task; it takes literally a few moments, and all you need is a bit of running water and a dry cloth.

 

A portable air conditioner is not only convenient but also a real help in maintaining comfort during heatwaves. However, to operate effectively and economically, it is worth following a few simple rules: set it up properly, ensure sealing, set a reasonable temperature, and take care of its maintenance. In Termofol's offer, you will find efficient, mobile air conditioners with eco-friendly refrigerant R290, which are perfect for apartments, homes, offices, or holiday apartments.
