My mobile air conditioning is not working optimally. What is wrong or how can I improve it?

We would like to ask you to follow these steps:
- Check if the room is exposed to direct sunlight. Close all curtains to keep out the heat;
- Close doors and windows;
- If there are many people in the room, the temperature will rise. This makes it more difficult to reach the desired temperature;
- Check if there is anything in the room that can generate a lot of heat (e.g. a microwave oven).
- Check whether the filter is dusty or dirty;
- Check whether the air inlet or outlet is blocked;
- Check whether the room temperature is lower than the set temperature. Is that the case? Then the unit is not cooling.

If this does not solve the problem, please contact us at service@duux.com
