We're very sorry to hear that your mobile air conditioning seems not to be working as it should or as it previously did. In general it is good to know that a mobile air conditioning can't compete with the cooling results of an integrated air conditioning with an outside unit; with a mobile airco you can expect a result of a max. temperature decrease of around 3 to 5 degrees Celsius. This also depending on a lot of external factors. Regular maintenance can help prevent issues and ensure an optimal performance.
If your mobile air conditioner is not cooling effectively, here are some steps you can take to troubleshoot and potentially resolve the issue:
- Check the Basics:
- Ensure the air conditioner is plugged in and the power switch is on.
- Make sure the thermostat is set to "cool" and the temperature is lower than the current room temperature.
- Inspect the Filters:
- Dirty filters can restrict airflow and hinder cooling. Clean or replace the filters according to the instructions in the user manual.
- Examine the Exhaust Hose:
- Ensure the exhaust hose is properly connected and free of kinks or obstructions. It should extend out of a window or door to expel hot air.
- Room Conditions:
- Close (and keep closed) all doors and windows to prevent warm air from entering the room. Also, check if the room is exposed to direct sunlight and consider closing curtains to reduce heat.
- Check for Refrigerant Issues:
- If the unit is old or has been leaking, it might have low refrigerant, which requires professional service to recharge.
- Check for Error Codes:
- Check the user manual for any error codes displayed on the unit and follow the specific troubleshooting steps provided.
Also good to consider and check:
- Does the room not exceed the maximum volume indicated on the packaging?
- Are there any heat sources in the room, such as appliances that are on?
- Is there no way to hot air can come in the room? Like when the window kit is not closed completely?
- Is the air inlet of the air conditioner free of obstacles?
- Are the air conditioner's filters dirty or aren't they cleaned recently?
- Is the sun shining continuously on the room/area?
- Is it a poorly insulated room?
Finally, check if the air conditioner is blowing out cold air by holding your hand in front of the outlet for five minutes after switching on. Is the air cold? Then your air conditioner is working properly. If the air is not cold, this may indicate a malfunction.
If these steps do not resolve the issue or clarify expectations, it may be necessary to contact the store where you purchased the air conditioning to start up the warranty process.
